In our factory we have a large availability of medium voltage switchgears both of

new construction (brand new) or second-hand (duly revised).

Generally speaking the units available in our stock can be modified or adapted to

the customer’s needs or requirements (for example as current/voltage transformers,

auxiliary control voltages, type of electronic overcurrent protection relays etc.).

Mainly two version of MV switchgears are available:

A) METAL CLAD construction with drawable circuit breakers and with the

relevant fixed cubicle.

Normally for high breaking capacity: more then 16 kA.

B) METAL ENCLOSED construction with disconnecting switch (air insulated

or SF6 filled) on the top and a suitable circuit breaker (vacuum, SF6 filled or

minimum oil type).

The panels include current transformers, overcurrent protection relays, earth

connection for outgoing cables etc.

The standard breaking capacity is 16 kA.
