Resistors for EMU
An Electric Multiple Unit or EMU is a multiple unit train consisting of self-propelled carriages.
This typology of vehicles doesn’t require a separate locomotive as electric traction motors are incorporated within a number of the carriages.
They are mostly used for passengere trains ad are popular on commuter and
suburban rail networks having the characteristics of fast acceleration and pollution-free operations.
The main features of the resistors for EMU are
High capacity of overload
High insulation level
Natural or forced air cooled
Installations under frame or on the roof
Safety heating shields for the external parts
Resistors for Metro
In recent decades Metros have had significative evolutions in order to be abreast with the times and
are the most effective answer for the big cities to the traffic problems and air pollution.
Reliability, efficiency and reliability are the key points and winning for the products used on this typology of railway vehicles.
The main features of the resistors for Metro are
Low air output temperature
Installations under frame
Natural or fraced air cooled
Safe system for the support of the resistor banks during maintenance operations
Resistor Protection system from the over-temperatures (patented)
The CGC series of Telema contactors are specifically designed for use in a railway environment.
Strong and continuous vibrations, heavy duty cycles, limited space available and
extended temperature range are just some of the criteria that have been taken into account in the design of this product family.
The result is a very thin component, the best in class for similar electrical performances.
According to Telema mission “Global experience, local content”, this new series of contactors can be produced everywhere among Telema group facilities all over the world,
according to specific localisation requirements of every project.
The self-supplied magnetic arc blow-out technology is available for both AC and DC versions, as well as in bipolar and
tripolar versions, in order to get the best flexibility toward the customer needs and his application layout.
Another degree of flexibility to our customers is personalization of interfaces that, where possible, follow the mounting requirements within their frameworks.
The availability of 2D and 3D drawings facilitate the installation checking as well as the early optimization of the arrangements and connections in the design phase.
