In response to safety and accessibility issues, electric mobility has become an increasing concern to local authorities in recent years. In light of the growing demand for fleets of electric vehicles available to all, and more environmentally-friendly public transport, PVI has embarked on the adventure. How has PVI developed its range, and why has it joined forces with MARECHAL ELECTRIC to provide secure and reliable electrically-operated connections?

With more than 20 years’ experience in industrial vehicle production in Gretz-Armainvilliers (Seine-et-Marne), PVI (Power Vehicle Innovation) has focused development on alternative energy sources for industrial vehicles - electrical mobility. It launched its first electric vehicles in 2010:

• OREOS 2X (22 seats) and OREOS 4X (49 seats) electric buses
• Commercial vehicles
• 26T household waste collection vehicle (in 2011).

Today, around fifty of the new generation of 100%-electric industrial vehicles are in use in France. Epvre DELQUIE, Sales Director of PVI, plans to double this figure by the end of 2012.

PVI chose to equip its OREOS buses with DS decontactors. The DS1/DS3/DS6 ranges ensure absolute safety when connecting and disconnecting while recharging the vehicles.

Compactness: 2 in 1 electrical socket

Epvre DELQUIE chose to install MARECHAL® sockets in the OREOS 2X and OREOS 4X electric buses, because they are equipped with unique technology. "The disconnect function is integrated into the socket". This patented system allows the socket to be incorporated into the vehicle recharging panel. The compactness and integrated safety guarantee easy installation into a panel fitted with a lid. In addition to automatic sealing of the IP66/IP67 socket, this panel ensures a second level of protection for the entire connection system.

Simplicity and reliability for local authorities and public service authorities

The DS DECONTACTOR™ socket can be used by anyone, without certification or any special training. Simplicity and reliability are the guiding principles which local authorities have chosen to follow for equipment that is needed 365 days a year. The collaboration between PVI and MARECHAL ELECTRIC provides optimum performance in terms of strength and durability, as well as being ergonomically sound and easy to use.

The year 2012 means the 60 years of development of the company and a new beginning for the brand MARECHAL®.

This new design complies with the Group strategy to go on developing itself with a unique brand by bringing together all entities (production or assembly sites) under one institutional and technological logo:

MARECHAL ELECTRIC (France),

TDI (Spain),

ISV (Germany),

MARECHAL AUSTRALIA (Australia),

HYCON (South Africa),

MELTRIC CORPORATION (USA).

The new design shows the M of the MARECHAL® brand and the technology inside the plugs and socket-outlets: The MARECHAL system combining a crimped braid with a spiral spring produces performance levels and strengths beyond standard receptacle concepts.

The Hanover Fair, the most important industrial fair in Europe, was for MARECHAL ELECTRIC GROUP (MEG) a great success both internally and externally, beyond expectations.

The Group was able to show throughout this event an overview of its unique technology.

The DECONTACTOR technology was highlighted at the show and is available on many products MARECHAL. It represents a reliable and sustainable response for many applications in all industries.

Many customers and people visiting us were able to measure the performance and adaptability of our technology and our solutions to their specific expectations as standard in their industry.

The celebration of 60 years at the event also provided an opportunity to bring together all the Group entities under a single and new visual identity. A new logo and a new design are now common for the whole MARECHAL ELECTRIC GROUP. It aims at increasing the visibility of our brand among all markets in which MEG is known on its own or with partners.

Before the flights, connectivity is grounded !

Whatever the size, activity, use of different aeroplanes of the Air France fleet, the maintenance operations take place within the hangars of Air France Industries in Roissy-CDG95. On a daily basis, the technical teams are faced with demand for electrical power and equipment mobility in order to control all systems and equipment on board the aircraft, including the A380.

A multi-site plug with multiple applications!
MARECHAL Electric’s historic partner since 1953, Air France Industries chose these industrial plugs, sockets and boxes to cover all their requirements on site.

There are three main Air France bases -Roissy/Orly/Toulouse - where plugs and sockets are installed for the following applications:

- Power for the hot and/or cold pre-conditioning of aircraft in areas away from terminals (ground pits equipped with MARECHAL sockets for the connection of mobile units at the foot of the plane),
- mobile lighting banks for the A380 and for safety when parking the aeroplanes, to ensure maintenance, loading and unloading
- electrical power connections for Aeroport de Paris’ fire engines

- The terminals: doors equipped with DS9 on tracks and footbridges with a micro-switch for heating (passenger comfort) or emergency cooling (backup power via mobile devices), in the case of the malfunctioning of the heating and cooling element sleeves for the preparation of the aircraft before before embarkation of passengers,
- The maintenance (connection of tools and docks) of aeroplanes in the Air France Industries hangars (H6 at Roissy for the 6 A380 Air France aircraft)..

Planning and maintenance of power in 3x8
Within the H6 hangar, dedicated to the maintenance of the long-haul AIR FRANCE fleet and more particularly the A380, the maintenance departments comprises approximately one hundred technicians. These technical teams take it in turns for 2 consecutive weeks in groups of 3x8 and use these plugs at medium and high power.

These plugs were deployed:
- on Bollards or in pits

Featuring plugs, computers, telephones, fibre optics, water and air, they were designed to provide the energy necessary for the proper functioning proper functioning of the aircraft’s circuits whilst on the ground. When the pits are closed, they withstand the weight of the aircraft.

- Pits placed in the ground (23 in total in the H6 hangar)
provide the services to several types of smaller aircraft (excluding A380) thus allowing the completion of maintenance within the H6 hangar and to be closer to the parking stand of each of these in the hangar.
> DS2 250A DecontactorTM with latch for secure and quick connection of motors or generators

- Power Distribution Boards
provide power into the aircraft aisles for both hand tools and portable lighting systems
> DN1 30A - 230V

Each of the above applications has its own benefits. In one they provide user safety, electrical performance and reliability whether used frequently or infrequently. Over periods of time they guarantee the user sound connections with time-saving load-break performance be it on the ground or on the access structures around the aircraft.

Impact resistance, pollutants and corrosive liquids

The deployment of distribution boxes and other mobile enclosures necessitate the use of and space for numerous cables both on the hangar floor and on the access rigs. These cables are regularly used on the floor together with their Marechal plugs and sockets. Being designed to withstand harsh environments, they resist the typical wear and tear caused by daily use on the hangar floor offering up to IK09 depending on the socket range.

Moreover, all hydraulic circuits of the aircraft are filled with a liquid called Skydrol. This hydraulic fluid is both fire-resistant and non-corrosive and is widely used in aeronautics.

As the industrial plugs are in contact in numerous areas where Skydrol is present, they have been tested by immersion in it to meet the needs of resistance and sealing (IP66/IP67) to this highly corrosive product.

Major player and worldwide specialist of electrical connections for industry, the service sector and infrastructures, MARECHAL Electric markets a significant range of solutions. The latest solutions, both those forming part of standard ranges as well as those which are customised, meet the requirements and expectations relative to certain applications.

A diverse offer of power connectors, boxes and accessories for all applications within the food industry sector: silos, production lines, packaging components, motors, ... a substantial number of the aforementioned are restricted by humidity and cleaning issues.

When some of these elements are combined, for instance, when producing concentrate fruit juice, the restrictions are greater. In order to respond to these different requirements, many companies within the sector use MARECHAL products…

… for instance the Eckes Granini France Company.

Established in Mâcon in 1936, and boasting a significant range with more than 250 products, the Eckes Granini France Company is only all too aware of its restrictions, which it faces on a daily basis. Following its expansion in 2010, the Company continues to use MARECHAL Electric power connectors on its production site to connect mobile equipment and additionally, confirms the suitability of Marechal power connectors with regards its requirements.

- Pump supply (near tanks),
- Stainless steel box equipment to feed the discharge machines and for preparing the fruit juices
Stainless steel boxes equipped with Decontactor TM DSN1 - 20 A, DSN3 - 32 A and DSN6 - 63 A.

Safety and Waterproof qualities
Within an environment constantly exposed to humidity generated by the production of fruit juices (Joker, Réa and Granini) and high-pressure cleaning, the DSN decontactor is equipped with waterproof qualities standard IP66 / IP67, applied to each connection.

Versions 20, 32 or 63 A boast an additional feature. This feature ensures the safety of the operator at each connection. The protection is useful both with the socket plug connected or the cover closed.
Everybody is able to use it. The socket plug is released by simply pressing the button above the power connector. Operators can rapidly and in a single action also manipulate 63 A connections.
The guarantee of safe installation, flexible in terms of configuration and progressive in terms of maintenance...the decontactor simultaneously serves multiple functions in complete confidence.

Resistance to cleaning and impact

The materials selected to cover the socket and connector allow for durability. In essence, the MARECHAL electrical power connectors are equipped with a PBT (polybutylene terephthalate) coating, with glass fibres. This guarantees resistance to corrosion and impact.
The decontactors include nickel-silver butt contacts and metal jumpers, which guarantee high, consistent electrical performance even after hundreds of operations.

One of the biggest challenges of building the longest non-estuarial road tunnel in the UK is making sure that people have sufficient time to escape from the twin tunnels in the event of a fire. For the Hindhead Tunnel, that means finding a way to maintain the power supply to the extractor fans despite extremely high temperatures.
The Hindhead Tunnel is a major construction project with a total cost of over £370 million. Running for 1.2 miles and with a maximum depth of 65 metres, the twin tunnels pass beneath the Devil’s Punchbowl, near Hindhead in Surrey, to complete the dual-carriageway link on the A3 bypass between London to Portsmouth. For users, the tunnel promises faster journey times; for local residents the tunnel will significantly reduce the traffic congestion that blights this area of out-standing natural beauty.
Work started on the project in January 2007 and the tunnel is scheduled to be open for traffic in July 2011. Among the state-of-the-art equipment that is being installed are safety and communication systems such as high-quality lighting and ventilation, as well as CCTV surveillance and radio re-broadcast systems. Maintaining power to these systems, and in particular to the extractor fans, is of paramount importance. Although the fans are routinely used to extract exhaust fumes from the tunnel at busy periods, they are also vital for extracting smoke in the event of a fire. Every minute that these fans can keep the tunnels clear of smoke, gives users more time to be safely evacuated.
The installation of the ventilator system is governed by safety regulations which state that the extractor fans must be capable of operating for a minimum of two hours even when the temperature reaches 250°C. Typically, this would mean that each fan would be hard-wired.
However, hard-wiring has its down-sides: Not only does it take a qualified electrician considerable time to install each fan, but it takes time, and a relatively high cost, for a qualified electrician to disconnect and reconnect the hard-wiring every time that maintenance is required. This means that lanes must be closed, and fans must be taken out of operation for unacceptably long periods even for routine maintenance.
The Hindhead Tunnel needed to address these issues to find a solution which would improve safety in the event of a fire, and minimise downtime and costs during routine maintenance.
In France, industrial connector specialist, MARECHAL had been considering the same problem. Their goal was to develop a connector technology which would combine very high-temperature operation with fast, safe connection and disconnection, even by operators without electrical qualifications.
For inspiration, MARECHAL turned to their existing plugs, outlet sockets and distribution boxes, developed for use in some of the most challenging applications. The result was wall-mounted socket-outlets and plugs capable, operating for up to two hours in temperatures of 400 degrees Centigrade, and with full compliance to the IEC EN 12101-3 fire safety standard.
The sockets comply with other standards too: They are sealed to IP55, which protects against dust and water from compromising their electrical performance; and they are rated to IEC EN 50102 standard, level IK09, which is the second-highest level of protection against shocks, allowing the sockets and plugs to withstand an impact energy of 10 joules from an object with a radius up to 50mm. This new high-temperature connector technology also allows the extractor fans in the Hindhead Tunnel to meet the IEC EN 60204-1 standard for electrical machinery, and the AC22 load-break requirements of the EN 60947-3 switch standard.
The original installation of mounting the sockets onto the tunnel wall, and fitting plugs onto the power cables to the fans, is carried out by a qualified electrical contractor. The power cable is wired onto steel terminals mounted on a fire-resistant ceramic base, and the socket-outlet is pre-wired to the same terminals using fire-resistant cable.
However, unlike the conventional alternative of hard-wiring the extractor fans, once the socket-outlets and plugs have been wired-in, the fans can be connected and disconnected safely in seconds, even by operators with no electrical qualifications. This is due to a number of safety features which are built into the MARECHAL technology.
An automatic locking mechanism ensures a secure connection as soon as the plug is inserted into the outlet socket, whilst a quick-release, load-break button on the top of the socket triggers springs in the socket casing, and on the contacts, to break the connection at speeds which prevent arcing. This allows the plug to be disconnected from the socket in seconds, even by operators with no electrical qualifications. The load-break switch also eliminates the need for a pilot cable or for additional switches. When the plug is disconnected, the socket’s safety shutter shields the live contacts preventing operators from accidentally touching them.
In addition to the considerable maintenance advantages that the new connector technology provides, there is the further advantage of an extended operational lifetime. Inside each socket, spring-assisted conductor terminals provide resistance to shock whilst the braided butt contacts are tipped with solid alloy of 85% silver and 15% nickel to prevent corrosion. These features can extend the expected lifetime of the connectors to 15 years or more, regardless of how many times that it is connected and disconnected, even in the harsh environment of the tunnel. They also ensure that the connection can be broken when the plugs have not been removed for a long time. This is a common problem with force-fit contacts which can become cold-welded over time, making it difficult to remove the plug from the socket.
By breaking with tradition and being the first project to replace conventional hard-wiring with the latest high-temperature connector technology, Hindhead Tunnel has gained greater flexibility and a significant cost-saving during maintenance as well as giving users valuable time in which to escape from the tunnel in the event of a fire.
