LuGao stands as a dedicated outdoor vacuum circuit breaker manufacturer,DC Carrying Current Handcart Vacuum Circuit Breaker）is a control and protection device designed for the rated voltage of 24KV and 50HZ AC three-phase high-voltage distribution networks.Its primary function is to interrupt and close load currents, overload currents, and short-circuit currents in power lines.This breaker is well-suited for protection and control applications in substations and power distribution systems of industrial and mining enterprises. The circuit breaker adopts a column type and dry structure, ensuring reliable insulation, a long electrical life, and maintenance-free operation.These features make it particularly suitable for locations with frequent operation requirements.Additionally, it is well-suited for installation and use in rural power grids with limited overhaul and maintenance capabilities.It can also serve as a segment switch in the power grid, and with the addition of a controller, it can achieve automation in the distribution network.

Lugao's Oil Immersed High Voltage 330 KV Current Transformer is designed to operate in high-energy, high-heat environments. Encased in a steel tank filled with cooling and insulating oil, the oil-immersed transformer uses convection to circulate the oil, ensuring efficient cooling. This current transformer features proven techniques and decades of reliable operation. A hermetically sealed stainless steel bellows on top protects the transformer oil from moisture, extending its lifespan. An oil level gauge on the bellows allows for easy monitoring of oil volume. The base, treated with spray painting or hot galvanizing, provides high corrosion resistance. Backed by Lugao's advanced R&D, robust production capabilities, and extensive application in various industries, this transformer guarantees reliability and performance.
