High voltage disconnect switch with Anti-Corrosion Technology DS23B 126kV 145kV 225kV 230kV 252kV 363kV 420kV 550kV

Product Introduction

Main Features

• The conductive parts adopt high-conductivity aluminum alloy, featuring good electrical conductivity, high mechanical strength, light weight and strong corrosion resistance, ensuring stable current transmission and long-term reliable operation of the high-voltage disconnect switch.
• The disconnect switch adopts a single-arm foldable telescopic structure, with driving components and balance springs sealed in the conductive tube, which is not affected by the external environment and has a compact and simple appearance.
• The plug-type contact of the high-voltage disconnect switch has self-cleaning performance, and the contact pressure is stable. When short-circuit current passes through, the contact clamping force will automatically increase, ensuring reliable contact and strong short-circuit current bearing capacity.
• The disconnect switch supports one-key sequential control "double confirmation" function expansion, which is convenient for intelligent operation and management.

Main technical parameters

   Among these voltage levels126kV-765kV non-standard custom manufacturing disconnector switch , the rated short-circuit breaking current is 63kA, and customization is available.
