Product Introduction

Product overview

 

HLVP-12 open type vacuum circuit breaker is an indoor high-voltage switchgear, which is suitable for use as a protection and control appliance in a three-phase power system with a rated voltage of 12 KV and a frequency of 50Hz. Due to the special advantages of the vacuum circuit breaker, it is especially suitable for places that need frequent operation under the rated working current or multiple short-circuit current interruptions.

 

 

Performance benefits

 

This type of product is a modular operating mechanism. The main insulation is solid insulation, and the vacuum arc extinguishing chamber is integrally cast in the epoxy resin insulation room. The adoption of this structure greatly improves the insulation performance of the product, and can meet the requirements of environmental conditions such as humidity and high altitude.
