It is suitable for power systems with a rated voltage of 10 kV and a rated frequency of 50 Hz or 60 Hz, and is used for voltage detection and supplying operating power for circuit breakers.This voltage transformer features excellent insulation performance, strong moisture resistance, and a long service life.

JSZW-10R VOLTAGE TRANSFORMER

This product model is an anti-ferroresonance indoor voltage transformer adopting an epoxy resin cast-insulated structure. It can operate normally for a long period even under 100% earth-fault conditions in the system. Meanwhile, the protection winding (da, dn) generates a 100 V voltage signal for the protection circuit.It is applicable to indoor AC power systems with a rated voltage of 10 kV and a rated frequency of 50 Hz or 60 Hz, and is used for voltage measurement and relay protection.The product is equipped with a 220 V power winding, which can provide the operating power required by ring main units (RMUs).
