The JDZW-24kV voltage transformer from Lugao delivers precise voltage to voltmeters, power meters, grounding relays, and leak detectors, ensuring reliable grounding alarms and leak detection. Ideal for 50Hz and 60Hz power systems with rated voltages up to 24kV, this transformer is perfect for outdoor equipment. Backed by extensive R&D, robust manufacturing capabilities, and a proven track record of successful partnerships, Lugao guarantees high-quality performance and ample stock to meet your needs.

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.

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.

Lugao's GW4 Series disconnectors are easy to operate, install, and maintain. They are used to connect or disconnect high-voltage circuits under load. They can also be used in scenarios such as isolating incoming and outgoing lines at substations. Lugao has the ability to mass-produce them quickly to meet customer needs.

Lugao's 220kV porcelain-insulated Surge arresters are overvoltage protection devices suitable for use in large substations and UHV transmission lines. Lugao utilizes leading edge porcelain sintering technology and a dedicated production line, capable of producing hundreds of units per month. These products fully comply with GB and IEC standards. Each arrester undergoes comprehensive type and factory testing to ensure reliable product quality.
