MV-CONNEX 10kV to 52kV
TION
The MV-CONNEX range is typically used in ring main
units, circuit breaker switchgear, high voltage motors,
transformers, capacitors, transducers and sealing boxes.
The plug is suitable for all kinds of insulated plastic
cables. In addition to the standard plug and socket
combination, there are many other versions for testing
purposes and special applications.
