JSZW12A-10NFR Voltage Transformer

This product is an indoor dry-type, three-phase four-wire unit with epoxy‑resin cast insulation, equipped with high‑voltage fuse protection and featuring ferroresonance suppression. It is intended for use in 10 kV power systems operating at 50 Hz for voltage and energy measurement as well as relay protection, or to supply operating power and zero-sequence voltage to ring main units, serving as a complementary component for 10 kV ring main cabinets.

JZZV1-10 Combined Instrument Transformer

This product is a combined-type instrument transformer, primarily intended for use in power systems with a rated frequency of 50 Hz and a rated voltage of 10 kV or less, for purposes such as electrical energy metering, current and voltage measurement and monitoring, and relay protection. The device features tightly sealed terminals that provide both anti‑tampering and waterproof protection. It conforms to the State Grid's standardized external dimensions for 10 kV combined instrument transformers and can be equipped with an electronic tag for remote identification of transformer parameter information.

LMJZ-Φ160 Current Transformer

The LMJZ-Φ160 current transformer features a core‑passing design and potting‑type insulation, and is mounted on the solid‑encapsulated pole of a 35 kV switchgear for new energy applications. Its measurement accuracy can reach up to Class 0.2S, with a standard accuracy class combination of 0.5/5P20, thereby meeting the requirements for line current measurement and protection signaling. The product boasts a simple, robust, and reliable overall structure, lightweight construction, and compact footprint, making it well suited for 35 kV switchgear in new energy systems and capable of operating under a wide range of environmental conditions.
