Electromagnetic voltage transformer

JDZ18-10A

Electromagnetic voltage transformer

The JDZ18-10A electromagnetic voltage transformer is an indoor epoxy resin-cast, pillar-type, all-condition product. It is suitable for use in power systems of indoor installations with a rated frequency of 50Hz and a rated voltage of 10kV or less for relay protection and voltage and electric energy measurement. When the transformer is magnetized under rated voltage, it can withstand a 1-second external short circuit without damage and can be installed in various high-voltage switchgears.

Three-phase five-column anti-resonance voltage transformer for ring main unit

JSZWF-20r

Three-phase five-column anti-resonance voltage transformer for ring main unit

This product is a three-phase, five-column voltage transformer designed to meet State Grid standards. It uses a 4PT anti-ferromagnetic resonance principle, which prevents resonance and allows for long-term operation under various degrees of ground faults. The primary terminal is compatible with American-style 200A large-diameter axial connectors, and a dedicated fuse is installed inside the plug. It is used in indoor AC 50 or 60Hz, 20kV rated voltage power systems to provide a 220V power supply, voltage measurement, and zero-sequence protection.

Three-phase five-column anti-resonance voltage transformer for ring main unit

JSZWF12a-10r2

Three-phase five-column anti-resonance voltage transformer for ring main unit

This product is a large-capacity three-phase five-column voltage transformer designed based on the State Grid's standardized parameters. It adopts the 4PT anti-ferromagnetic resonance principle, and will not produce resonance when the system experiences ground faults of varying degrees, and can operate for extended periods. The primary terminal is compatible with the American-style 200A large-diameter shaft type, and a dedicated fuse is installed inside the plug. It meets the Southern Power Grid's requirements, with a short-circuit impedance of less than 15% when the power supply winding output is 3000VA. It is suitable for indoor AC 50 or 60Hz, 10kV rated voltage power systems, used for providing 220V power supply, voltage measurement, and zero-sequence protection.
