The LBZ-35W2 (LCWD-35) current transformer is suitable for use in power systems with a rated frequency of 50Hz and a rated voltage of 35kV for energy metering, instrument monitoring, and relay protection. It is particularly suitable for unmanned and oil-free substations to implement telemetry, remote signaling, and remote adjustment. It is an updated product of oil immersed transformers LB, LJW, and LCW (D).

The iron core of LBZ-35W2 (LCWD-35) current transformer is made of high-quality magnetic conductive material, and the secondary wire is uniformly wound along the iron core. The primary and secondary windings are poured in epoxy resin, which has excellent insulation performance and moisture-proof ability. The product is equipped with a ceramic sleeve on the outside, mainly insulated with electric porcelain, epoxy resin and special insulation materials. The product is not filled with oil, so there is no leakage problem, thereby reducing maintenance workload.

The LBZ-35W2 (LCWD-35) current transformer has three cores, namely three cores and three windings, which can be used independently for energy metering, instrument monitoring, and relay protection. It can also be tapped in the secondary to change the rated transformation ratio of the transformer.

Rated voltage: 35kV;
Rated insulation level: 40.5/95/185kV;
Rated secondary current: 5A (or 1A);
Accuracy level: 0.2S, 0.2, 0.5S, 0.5, 10P10, 10P20 can be combined arbitrarily, while the conventional level is 0.2/0.5/10P
