VSP5-12 Column mounted vacuum load switchDetailed product description：

The VSP5-12 column mounted vacuum load switch is suitable for outdoor three-phase AC distribution systems with a rated voltage of 12kV and a rated frequency of 50Hz, and is used for opening and closing load currents and closing short-circuit currents.

VSP5-12 column mounted vacuum load switch is suitable for protection and control in substations, industrial and mining enterprises, urban and rural power grids, as well as in automated distribution networks and frequently operated places.

Product structure and features:
1. Excellent breaking performance: By introducing Toshiba technology and catching up with Japanese technology, the expansion design has been carried out to increase the short-circuit current to 20kA. Vacuum arc extinguishing and SF6 gas insulation are used, and the switch has an isolation fracture connected in series with the vacuum arc extinguishing chamber, resulting in superior arc extinguishing and voltage resistance performance. The action sequence between the two is ensured by the mechanism (the vacuum arc extinguishing chamber is first disconnected and then closed, and the isolation knife is first closed and then disconnected).
2. High safety: Both arc extinguishing and insulation media are oil-free media, and explosion-proof devices are installed on the top of the box. Even in the event of an unexpected internal failure, there will be no leakage of high-temperature gases or splashes.
3. Maintenance free: The main circuit and operating mechanism of the switch are sealed in a box with SF6 gas as the medium; The main circuit of the switch is led out using cable heads or our patented corner sleeve.
4. Due to the use of zero gauge pressure SF6 gas insulation, the switch has a compact and compact size, while minimizing the risk of gas leakage. It has manual/automatic operation, making the switch operation flexible. Equipped with electromagnetic operating mechanism and electrical maintenance. Power on closing, power off opening, simple and reliable structure.
5. Flexible installation method: Column mounted lifting or sitting installation can be used.
6. Equipped with an automated distribution interface: It can be equipped with current transformers of various ratios for measurement, protection, and metering, as well as remote control auxiliary contacts.
7. High reliability: With over 30 years of vacuum equipment technology and practical experience from Toshiba in Japan, our company's comprehensive quality management system ensures high reliability in production. The SF6 gas filling pressure is zero gauge pressure, which is not prone to leakage. The reliable sealing technology ensures that the gas inside the switch can work normally for 20 years (based on our operating experience in Japan).
