Mont-Ele - Switchgears and Relays

Mont-Ele has been working in the transport sector since 1972. Nowadays it is one of the leading companies in the international market for turn-key projects for DC traction substations, supplying all DC section, DC Switchgears, rectifiers.

The new automation and control division allows full management of the substation with the latest control technologies.

DC traction substation

Thanks to more than 35 years of experience and to the skill team, Mont-Ele can supply a turn-key system for the DC section, starting from engineering, production, manufacturing, DC system integration, test, installation and starts-up, up to service after commissioning, becoming leader supplier for the DC section.

We can supply turn-key DC systems, for railway, metros, tramways and trolleybuses (3kV - 1,500V - 750V DC systems).

DC switchgears withdrawable solution

Mont-Ele has engineered and manufactures the range of products called "railway energy". The DC metal-clad switchboards, are standard modular units in total withdrawable solution, which allow various configurations for the feeding of traction systems (tramway - underground railway - trolleybus - etc) at a voltage of 575-750-1500Vdc.

The standard modular units, even if standardized,  can be adapted to suit the needs of projects of any type; mainly, they allow the utilization of components made by different manufactures, to satisfy costumers’ preferences as to standards, spare parts, applications, etc.

The DC distribution switchboards are in accordance with EN 50123-6 and IEC 61992-6 standards. It includes DC switchgears as feeder cubicles, rectifiers, negative and measure, on-load disconnectors, filter units, two-pole disconnector units, with withdrawable execution and the internal arc fault.

Our engineering department designs all the equipments according to client requests and according to international standards, finding the best solution for saving space and guarantee easy maintenance and high safety.

DC protection relays

The multifunction protection relays ME-MPS offer a wide range of possible applications in DC system for railway, tramway and metro applications. The protection relays, connected with suitable measure sensors, guarantee an high degree of protection, control and diagnostic of the line and of the plants where installed.

The ME-MPS21 is able to recognize the fault type that has caused the interventions analyzing and recording the input variables, optimizing the interventions and consequently improving the reliability and availability of the traction plant.

It is according to international standards IEC 60255 - IEC 61000 - EN 50263 - IEC 60068.

DC switch disconnector

The MOS DC switch-disconnectors are designed and produced with electrical and mechanical characteristics, equipped with special snuffer chambers, suitable to be installed in metal-clad cubicles or switchboards. They offer a wide range of possible applications in the railway traction system ( railway underground, tramway and trolleybus) for a rated voltage up to 3600Vdc. In particular, they can be used for the following applications:

• First line switch disconnectors
• Second line switch disconnectors
• DC feeding line disconnectors
• Earthing switches
• DC switch disconnectors for tunnel
<;i>Current switch disconnectors
• Voltage switch disconnectors

Voltage transducers - current transducers

The measure transducers for voltage and current measure on DC systems are used on railway, underground and tramway traction systems, in naval and industrial sectors.

The engineering of measure devices, both in terms of constructive solutions, components choice and performances, hold in consideration the significant experiences dues by Mont-Ele in the applications and in the operation of traction systems.

The transducers are composed by: transmitter unit, receiver unit and fibre optic link, connected through plastic 1,000 micron without St connector fibre optic, that allows a total galvanic isolation.

Prefabricated substations

The prefabricated transportable substations completely designed and manufactured by Mont-Ele, are complete conversion units. Particularly suitable for solving the space problems, they allows to make up for the time and costs for construction.

Furthermore, they are suitable for assembling on street or rail trucks, can be used as itinerant emergency substations, to solve problems of energy availability.

Integrated quality system

Mont-Ele is certified by the international Quality Management System TÜV according to UNI EN ISO 9001:2008 (quality) , UNI EN ISO 14001:2004 (environment) and BS OHSAS 18001:2007 (safety)
