JKF

CURRENT TRANSFORMERS | INDOOR OPERATION

  • Suitable for installation over fully insulated HV and MV cables
  • Suitable for Installation on bushings
  • Wide range of geometric dimensions
  • Any Installation position

Cable current transformers type JKF are used in outdoor switchgears. They transform high currents up to 4000 A into standardised values for meters, measuring and protection devices.

General description

Cable current transformers type JK are used in outdoor switchgears. They transform high currents up to 4000 A into standardised values for meters, measuring and protection devices.

The outdoor Version of the cable current transormer is designed for Installation on fully insulated medium and high voltage cables or for Installation on medium and high voltage bushings. This enables space-saving System design. Primary currents of up to 4000 A can be measured.

A specific core padding and the complete casting of all active parts in cycloaliphatic epoxy resin suitable for outdoor applications ensures that the magnetic properties, and therefore the class accuracy, remain constant for decades.

The standard secondary terminal box Permits a housing degree of protection up to IP 65.

 

 

Thanks to a wide range of geometric dimensions the cable current transformer can be adapted to customer requirements. Applicable installation options are also available in various designs, as well as any type of installation position.

The transformers are designed according to applicable national and international standards. Designs that meet customer-specific standards are possible on request.
