China Compact Substation Switchgear Manufacturers, Suppliers, Factory

Lugao is a voltage transformer manufacturer with 15 years of professional experience. This voltage transformer is designed and manufactured based on IEC 61869-1/3. 220kV Inductive Voltage Transformer is for Turnkey Substation use,outdoor rated distribution class inductive voltage transformers are of compact single-phase designs and intended for connection between phase and ground (single bushing) to provide critical voltage measurement information. Hermetic sealing of the design is accomplished using a gas cushion above the oil to prevent free-breathing outside moisture-laden air.

LuGao is a Indoor Epoxy Resin Casting Current Transformer manufacturer. Indoor Epoxy Resin Casting Current Transformer adopts epoxy resin as the main insulation and strengthens the external insulation.The primary winding and part of the secondary winding are cast into one by resin, and the other part of the secondary winding is exposed on the iron core.

LuGao stands as a dedicated 40.5KV High Voltage Outdoor SF6 Gas Circuit Breaker manufacturer,SF6 Gas Circuit Breaker pts the fully enclosed structure, and the secondary winding is sealed in the epoxy resin casting body to ensure the insulation performance. The LW8-40.5Y SF6 Circuit Breaker boasts a robust mechanism with a service life exceeding 3000 operations, ensuring long-term reliability.Its sealing performance is dependable, employing imported sealing rubber pads.The dynamic seal incorporates a "V"-type sealing ring with a spring pressure compensation structure, and the secondary terminal board, provided by a cooperative enterprise, ensures an annual air leakage rate of less than 1%.Additionally, the built-in current transformer adopts a fully enclosed structure, with the secondary winding sealed in epoxy resin casting to ensure optimal insulation performance.

Experience superior protection with Lugao's 33KV 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's GW4 35kv Outdoor Vertical Operate Type Three Phase Disconnect Switches are suitable for high-voltage busbars, circuit breakers, and other electrical equipment. They function as switches when high-voltage lines are operating without load. They are primarily made of copper, with aluminum alloy conductive tubing used for the grounding blades. Exposed metal parts are hot-dip galvanized. They offer excellent performance at an affordable price.

The 110kV Porcelain Housed Station Class Metal oxide Surge Arrester produced by Lugao are mainly used to limit lightning overvoltage and operational overvoltage. They are electrical protection devices for substations and power plants. The product complies with domestic and international standards such as GB and IEC, and has passed type tests and multiple reliability certifications. Each lightning arrester has undergone strict factory tests, including tests for power frequency withstand voltage, partial discharge, and DC reference voltage. Lugao is designed for sufficient reserve inventory, which can meet the large-scale requirements of customers.
