12KV Fixed AC Metal Enclosed Switchgear rmanufactured by Lugao.specifically designed for secondary distribution applications.This air-insulated switchgear represents a balance of economic considerations and advanced functionality, incorporating an SF6 gas load break switch in conjunction with either a Vacuum Circuit Breaker (VCB) or Gas Circuit Breaker (GCB).With a focus on cost-effectiveness and versatility, the HXGN-12 type switchgear stands as a dependable solution for a variety of needs within secondary distribution systems.

12KV Ring Main Unit Switchgear Panel manufactured by Liugao.The HXGN15-12 metal-clad ring main unit switchgear, of the intelligent type, is designed for application in a three-phase AC system with a rated voltage of 12kV, a rated frequency of 50Hz, and a rated current of 630A.It serves the purpose of ring network electricity supply and radiation terminal power supply, particularly in cable line sectionalizing and branch connection scenarios.The switchgear is equipped with an SF6 gas insulating multiloop power unit and a feeder terminal device (FTU) imported from Korea.Notably, it features advanced functions such as remote signaling, telemetry, remote control, and fault current detection.Primarily utilized as a distribution automation system, it proves beneficial for city power supply load centers and cable supply applications.

Experience superior protection with Lugao's Polymer Housing Metal-oxide Surge Arrester, designed for medium/high voltage AC networks. Ideal for transformers, including those in arc furnace applications, and railway vehicles, this arrester shields against atmospheric, switching overvoltages, and Very Fast Transients (VFT). Featuring a robust, maintenance-free design that complies with IEC60099-4 and IEEE C62.11 standards, Lugao's surge arrester ensures stable, reliable performance in the most demanding environments.

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 Power Co.,Ltd. has a specialized workshop dedicated to producing high-voltage SF6 gas circuit breakers. Its design technology is industry-leading. The LW series SF6 circuit breakers utilize a single-pressure arc extinguishing chamber and self-energized arc extinguishing technology, using sulfur hexafluoride gas as both an insulating and arc-extinguishing medium. A separate arc extinguishing chamber generates airflow during the opening process, cooling the arc and interrupting the current.
