Ahg70V12/- /3 Solid Insulation Ring Net Cabinet Movement

Product Description

Product overview:
Solid insulated switch is the core of solid insulated ring network cabinet. It is an integrated design of vacuum circuit breaker or load switch, isolation switch and grounding switch. It has a compact structure and adopts front and back arrangement. Reduce the intermediate unnecessary transmission link, save labor, save parts, high transmission efficiency. The primary part adopts the APG automatic gel process, and the vacuum isolation chamber and the isolation and grounding switch of the primary part are completely sealed in special epoxy resin, which is used as the solid sealing pole unit with superior insulation and electrical properties. Solid insulated switch can be integrated as a module and switch cabinet assembly into different functional units; The operating mechanism of the switch and the operating mechanism of the isolation switch and the elastic operating mechanism of the main switch have been realized interlock, and the parts of the mechanism are less, reduce the unnecessary transmission link, high reliability, and the isolation switch can be electric operation according to the needs of users.
. Pole unit integration, high climbing distance, with excellent electric field performance.
. Using vacuum arc extinguishing chamber, knife and brake isolation, grounding switch.
. The switch body has high protection grade and anti-condensation function.
. Main bus outlet and cable outlet adopt standard European joint, easy to assemble cabinet, safe and reliable
. Special epoxy resin insulation material.
a. High mechanical strength.
b. Good cracking resistance, thermal shrinkage, thermal conductivity and aging resistance. c. The high glass transition temperature is greater than 110C, so that the insulation ability of epoxy resin does not decrease under the high temperature operating environment.
The isolation switch can be electrically operated according to the needs of users, which can truly realize the automation of distribution network
Easy maintenance, open the panel for parts replacement and line inspection.
