Its exceptional suitability for applications in metallurgy and electric arc steel-making, where frequent operations are essential, sets it apart. Compliant with the GB 1984-89 "AC High Voltage Circuit Breaker" standard, LiuGao invites you to experience cutting-edge solutions that redefine reliability and performance in indoor vacuum circuit breakers.

LuGao stands at the forefront as a committed manufacturer of outdoor SF6 circuit breakers, showcasing cutting-edge engineering.The 220KV SF6 Heavy Duty High Voltage Circuit Breaker is meticulously designed with a fully enclosed structure, ensuring superior insulation performance by sealing the secondary winding in an epoxy resin casting body. This breaker is not just reliable;it's a powerhouse with a robust mechanism, delivering a service life of over 3000 operations for unparalleled long-term reliability.Dependable sealing performance is guaranteed, thanks to the use of high-quality imported sealing rubber pads.The dynamic seal incorporates a "V"-type sealing ring with a spring pressure compensation structure, and the secondary terminal board, sourced from a trusted cooperative enterprise, maintains an impressively low annual air leakage rate of less than 1%.LuGao invites you to embrace groundbreaking innovations that redefine the benchmarks of durability and reliability in outdoor SF6 circuit breakers.

Lugao takes pride in being a YB6-11/15/33/0.4KV Export Type American Prefabricated Box Substation manufacturer.The cable branch box features a compact structure, significantly reducing volume compared to European-style substations of similar capacity (1/3-1/5 the size).This design optimizes floor space utilization, providing an efficient solution. The Type American Prefabricated Box Substation adopts a whole-sealing and fully insulated structure, eliminating the need for insulation distance.This ensures enhanced personal safety through effective insulation measures. High-voltage wiring is versatile, accommodating both looped network and terminal configurations with high reliability and flexibility, adapting to various network setups. The transformer within the Type American Prefabricated Box Substation delivers excellent performance with low loss, minimal noise, low temperature rise, high overload capacity, robust impact resistance, and a high anti-short circuit capacity. The cable head offers two options: a 200A elbow connector and a 600A "T" type fixed cable connector. Both can be equipped with fully insulated ZnO lightning conductors.The 200A elbow connector is compatible with load plugs and features insulation switch functionality, adding to its versatility.

Lugao exports over 100 vacuum circuit breakers annually, demonstrating exceptional product quality. VS1 Fixed Type 24KV/36KV Indoor Vacuum Circuit Breaker are used in three-phase AC 50Hz indoor power distribution systems, quickly interrupting short-circuit currents and primarily protecting electrical equipment. The VS1 is compact and easy to install, requiring only regular inspection of contact wear.

Lugao's independently developed and produced Three-Phase High Voltage 35KV 40.5KV Vacuum Circuit Breaker With Transformer is suitable for inter-city power distribution networks, ensuring safe operation of the power grid and providing short-circuit protection. It has good sealing performance and is easy to install and maintain. It has been praised by customers at home and abroad.
