For decades, the fossil energy industry - and especially oil and gas production - has relied on Marechal® to establish the electrical safety of its installations. Our Ex connectors are used on operating platforms, Pipelines and refineries, and our products are well tested for a wide range of applications, such as load breaks, self-ejections or connection of boxes and outlets for automation and equipment management.

Today, it is difficult to reconcile an efficient process with a reduction of the costs on oil extraction. MARECHAL ELECTRIC has understood this and has products to meet the needs of this important branch of industry. From offshore oil rigs in the Gulf of Mexico to oil sands in northern Canada, we can count on our products to bring this essential resource to market.


We offer industrial electrical plugs and socket-outlets for:

  • Oil refineries
  • Natural gas prospecting
  • Production of natural gas
  • Refining crude oil
  • Offshore Oil Platforms
  • Oil wells
  • Storage of hydrocarbons
  • Hydraulic fracking

Solutions to your needs

Ensuring operator and infrastructure safety
Operators can connect and disconnect electrical outlets or in line coupler sockets without any supervision or special electrical training. Just press the button once to cut the power and eliminate the risk of electric shock; the plug is ejected automatically, disconnecting the appliance. Marechal® offers a range of electrical connectors and boxes that ensure the safe and efficient operation of a refinery, pipeline or gas pipeline.

Cost reduction
As gas and petroleum refineries strive to increase production in a market that is constantly changing, operating time, availability and safety are paramount to suppliers of electrical equipment. Marechal® sockets are used to simplify the processes and to optimize them. We are striving to develop industrial power sockets that enable oil and gas refineries to produce petroleum products reliably in the world at the lowest possible cost.

Improving performance and quality
Marechal® meets this market demand with products that improve yield and quality. From wellheads to final storage through to compressor stations, our power and Ex connectors are widely used in the fossil fuel market segment. 

Compliance with European standards for industrial sockets
The plugs and sockets as well as socket-outlet boxes and junction boxes in this range are meant for use in hazardous areas in compliance with the ATEX 2014/34/EU Directive and as per the IECEx in zones 1 and 2 (Gas) and zones 21 and 22 (Dust).

We advise you

DXN/DX DECONTACTOR™ plugs and sockets are designed for hazardous areas, with ‘de’ protection mode. They comply with the ATEX 94/9/CE Directive. They can be used in zones 1 & 2 (Gas) and zones 21 & 22 (Dust). They are certified according to IECEx standards.

Our multicontact connectors can hook up equipment to a power supply and transmit data. The silver-nickel alloy used for the butt contacts provides exceptional conductivity and longevity (can withstand several thousands of operations).

Thanks to their silver butt-contact technology, single-pole power connectors SP/SPeX admit a permanent current of 700 A / 1000 V ac or 1500 V dc. They are waterproof IP66/IP67 and have a reliable mechanical and electrical interlocking with pilot contact circuit.
