Cable Current Transformer JK

Cable current transformers type JK are used in indoor switchgears. They transform high currents up to 5000 A into standardized values for meters, measuring and protection devices. The cable current transformer is designed for installation on fully insulated medium and high voltage cables or for installation on medium and high voltage bushings. This enables a space-saving system design. Primary currents of up to 5000 A can be measured. A specific core padding and the complete casting of all active parts in polyurethane (PUR) ensures that the magnetic properties, and therefore the class accuracy, remain constant for decades. The standard secondary terminal enclosure permits a housing degree of protection up to IP 20. Optionally, secondary terminals can be integrated in a terminal box, providing a housing degree of protection of 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.
