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.

LZZB1-35W

The LZZB1-35W 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 is specifically designed to interface with equipment such as the ZW‑type 35 kV vacuum circuit breaker, offering superior dynamic and thermal stability, high accuracy, and large capacity.

LZJC-10Q

The LZJC-10Q current transformer is primarily designed for indoor power systems with a rated frequency of 50 Hz (or 60 Hz) and a rated voltage of 10 kV or lower. Its core functions are to accurately measure the current and electrical energy in the circuit and to provide signals to relay protection devices.

LXK-Φ（80-240）

The LXK series zero-sequence current transformers are primarily designed for small‑grounded‑current systems with a rated frequency of 50 Hz or 60 Hz and a rated voltage of 35 kV or lower. Their core function is to work in conjunction with DD‑11/60 or DD‑1/60 type relays and signaling devices, enabling the detection of zero-sequence (residual) currents in three‑phase power systems. When asymmetrical faults such as single‑phase-to‑ground occur, these transformers accurately sense the fault current and initiate the operation of protective devices, thereby providing grounding protection and monitoring for cables.

LSY107-10

LMZJ1-10

This current transformer is an epoxy‑resin‑cast, fully enclosed busbar‑type device. It is primarily intended for indoor power circuits and equipment with a rated frequency of 50 Hz or 60 Hz and a rated voltage of 10 kV or lower, where it is used for current and energy measurement as well as relay protection.

LMZ(1.2.3.4.5)D(G)

Low-voltage current transformers for metering are suitable for use as metering devices in 0.4 kV distribution lines within the State Grid Corporation of China system. This type of transformer complies with the standard Q/GDW 10572.1-2020.

LJZN(W)1(2)-10(20.35)G

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 can replace oil‑immersed LB‑type units, eliminating oil contamination and fire hazards, reducing maintenance requirements, and meeting the growing demand for oil‑free operation.
