Isolation Switch

The durable isolating switches produced by Sangao Electric are important electrical safety devices used to safely disconnect part of the circuit from the main power supply, making maintenance or repair work out from the risk of electric shock.

Isolating switches play a vital role in various applications, including power distribution systems, industrial machinery and equipment, renewable energy systems, HVAC systems, manufacturing and processing industries, and data centers. By providing clear physical isolation and effectively interrupting the current, isolating switches can protect personnel and equipment from accidental contact with live parts and are an indispensable component for the safe operation of modern electrical systems.

Zhejiang Sangao Electric Co., Ltd.'s featured products include high voltage vacuum load switches, Isolation Switch, high voltage load switches, vacuum circuit breakers, high voltage vacuum contactors, isolating switches, earthing switches, high voltage fuses, lightning arresters and operating mechanisms. These products are widely used in urban and rural power grid transformation, power transmission and distribution projects, sewage treatment, hydropower stations, wind power plants, metallurgy, petrochemicals, mining, railways, residential buildings and power engineering. We maintain close cooperation with well-known technical institutions such as Xi'an Senyuan, Beijing Electric Power Research Institute and Xi'an High Voltage Electric Research Institute.

Outdoor Isolation AC Switch

The Sangao High Quality Outdoor Isolation AC Switch consists of three identical single pole isolation switches, which are installed as a unit through a tubular connecting rod and equipped with a manual operating mechanism. Each single pole isolation switch has an independent iron frame, with two post insulators installed at both ends and contacts mounted on the post insulators. There is a rotating shaft in the middle of the iron frame, and the knife switch is opened and closed with the help of a pull rod insulator. Each pole has two pillar insulators fixed on both sides of the base, with a pull rod insulator, a crank arm, and a rotating shaft in the middle to open and close the switch. The switch can be equipped with an anti-theft operating mechanism or a common operating mechanism.
