Outdoor current transformer cable KOKU

Current transformers cable type KOKU are suitable for measuring of phase currents in low voltage switchgear.

A current transformer without primary conductor and primary insulation of its own, which can be mounted over an insulated cable. An uninsulated busbar or low voltage cable serves as the primary conductor.
Series KOKU current transformers can also be used for measuring the phase current at voltages even higher than 0.72 kV (for KOKU 072 G4) or 1.2 kV (for KOKU 1), if the insulation of the high voltage primary conductor fulfils the respective standards for the operating voltage. The secondary winding and ring shaped iron core is cast in resin which has good electrical and mechanical properties.
