Overview

Description: Sichuan customized 35KV high-voltage isolation switch is not suitable for places with flammable substances, explosion hazards, chemical corrosion, and severe vibration. Explanation: When the above environmental conditions cannot meet the usage requirements, it shall be resolved through negotiation between the user and the manufacturer. This series of products meets the requirements of standards and IEC standards, with good seismic resistance and the ability to meet the requirement of a seismic intensity of 9 degrees.

Product Details

Sichuan customized 35KV high-voltage isolation switch

This series of products includes the following varieties:
1) Divided by the presence or absence of a grounding switch: ungrounded, single grounded (left and right grounded), and double grounded;
2) Grounding switches are classified into types I, II, and III based on their ability to withstand short-circuit currents;
3) Divided by usage area: ordinary type, anti fouling type, anti fouling type, and high-altitude type.
This series of products meets the requirements of standards and IEC standards, with good seismic resistance and the ability to meet the requirement of a seismic intensity of 9 degrees.
