High and Low Voltage Switchgear HXGN-12

LZZBJ9-10C(175b4)

This series of current transformers features an epoxy‑resin‑cast, fully enclosed insulation design. They are suitable for use in power systems with a rated frequency of 50 Hz or 60 Hz for electrical energy metering. These transformers eliminate oil contamination and fire hazards, reduce maintenance requirements, and meet the demands of oil‑free operation.

LZZBJ4-35

The LZZB current transformer is an epoxy‑resin‑cast, fully enclosed device, primarily intended for power systems with a rated frequency of 50 Hz or 60 Hz and a rated voltage of 35 kV or lower. Its core function is to provide high‑accuracy current signals for energy metering, current measurement, and relay protection. This model features excellent dynamic and thermal stability, high accuracy, and a large capacity.

LZZB9-10A

The LZZBJ9-10A current transformer is primarily designed for indoor power systems with a rated frequency of 50 Hz and a rated voltage of 10 kV or less (with a maximum operating voltage of 12 kV). Its core functions are to accurately measure current and electrical energy in the circuit and to provide reliable signals to relay protection devices. This model is widely used in indoor switchgear—such as center‑mounted switchgear and cubicle switchgear—as well as in complete high‑ and low‑voltage equipment sets.
