High electrical power : explanation and industries

What is a high current electrical socket outlet ?

A high current socket outlet has a capacity of more than 150 A in order to be able to connect large equipment and generators, in environments such as: mines and quarries (e. g. excavation machines), ports and shipyards (port equipment and ships), steel industry... What are the industries concerned by this type of socket?

There are various risks for connection to marinas (e. g. dockside boats) and shipyards (cranes, converters/compressors, etc.), but also for connections to mega yachts, military/commercial vessels and tugs:

- Corrosion due to salt,

- Humidity (salt fog),

- UV,

- Public manipulation....

...all of which will affect the power sockets at the ports.

The MARECHAL® solution: PF is one of the most popular solutions for this type of application. Indeed, it is suitable for this sector because of its ease of connection/disconnection and its marine treatment (resistance to corrosion and humidity resistance - IP66/67). 150/250 Amp (DECONTACTOR™ DS) and 700 Amp (single pole) socket outlets are also used.

This concerns applications such as the connection of excavation machines, generators, pumps or conveyor distribution boxes.

Extractive industries (quarries, underground and open-cast mines, tunnel and gallery construction) can generate high-risk situations for users: risks related to dust, stones, mud and water flows. We offer you robust industrial electrical connections for power supply, extraction and processing, which support you on all your sites for greater safety.

The MARECHAL® solution: DECONTACTOR™ DS 250 A for the extractive industry is widely used for the following reasons: waterproofness, ease of use, fast disconnection, robustness; for construction and infrastructure, DS 150/250 Ampere as well as PF and SP unipolar are preferred. All these solutions are particularly appreciated for their safety features.

In steel and metallurgy, it is necessary to connect electrically: furnaces, electromagnets or even gantries.

This type of industry is characterized by a dusty environment and high temperatures.

The MARECHAL® solution: for these sectors, the two most requested solutions are DECONTACTOR™ DS and PF. Their resistance to dust, impact and high temperatures justify this choice.
