HGW1 Outdoor Isolation Switch

The HGW1 series outdoor isolating switch is a high-performance medium-voltage device designed for outdoor power distribution networks ranging from 12kV to 40.5kV.

Capable of interrupting small load currents, this product serves as an isolation component for power transmission equipment and small-scale outdoor installations, ensuring safety by disconnecting power during troubleshooting and routine maintenance. Upon disconnection, it creates a clearly visible break, providing on-site personnel with reliable visual confirmation of isolation and minimizing the risk of accidental operation.

HGW1 series outdoor insulating disconnect switch utilizes compression-molded silicone rubber as its primary insulating material. These high-strength insulating components offer excellent resistance to aging, radiation, pollution, and moisture. Compared to traditional porcelain insulators, they are better suited for harsh outdoor environments and extreme climates, including areas prone to salt spray, industrial pollution, or arid conditions.

Its metal components and electrical connectors feature superior corrosion and oxidation resistance, ensuring long-term reliable operation in demanding environments.

HGW1 series outdoor insulating disconnect switch contact system is specially designed to maintain stable contact pressure under various operating conditions while minimizing contact resistance to prevent abnormal temperature rise.

The product supports both manual and electric operation modes to meet diverse technical requirements, ensuring the safe interruption of no-load transformer excitation currents and overhead line capacitive currents.

With a compact design that saves significant space, the unit offers precise mechanical operation and requires minimal routine maintenance, thereby reducing labor costs. It is widely used in applications such as off-grid substations, railway transmission lines, overhead line isolation for rail transit, distribution network upgrades, and environmental monitoring, serving as a highly reliable, high-performance isolation component in modern power distribution systems.
