These Outdoor Oil Filled 10KV Current Transforme manufactured by Lugao.This type of CT typically consists of a primary winding that is connected to the high voltage power line, and a secondary winding that is connected to a measuring instrument, such as a meter or protective relay. The transformer’s job is to step down the high voltage current into a lower value suitable for the measuring instrument to handle.

Lugao takes pride in being Gw1-24 Outdoor High Voltage Isolating Switch manufacturer,Gw1-24 Outdoor High Voltage Isolating Switch, as listed here, is specifically designed for switching stub lines and ring main lines, as well as transformers. Additionally, it can be equipped with MV HRC fuse links to serve as a short-circuit protection function. This versatile switch is suitable for various applications, including switching operations under on-load conditions, providing flexibility and functionality in a range of high-voltage scenarios.

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's GW4 Series 220kV disconnectors are double-column, horizontal rotary disconnectors suitable for outdoor environments, featuring high mechanical strength and excellent corrosion resistance. These 220kV disconnectors are primarily used for high-voltage side isolation in substations. During inspection or maintenance, the disconnector creates an air-insulated break, ensuring physical separation of the isolated equipment from the energized system. They can also be used with an earthing switch for safety locking.
