▸ Product Introduction

Product overview

BSD4-40.5 handcart indoor high-voltage vacuum circuit breaker is an indoor high-voltage switchgear developed by Co., Ltd., with a rated voltage of 40.5kV. It is suitable for industrial and mining enterprises, power plants and substations, and has the function of frequent operation. 

Core characteristics

Design concept: modular operating mechanism and electrical components are adopted, with compact structure and convenient maintenance.

Application scenario: it can separate load current, overload current and fault current, especially suitable for power system environment with frequent operation. 

Operating conditions: The operating temperature range is -15℃ to +40℃, which supports stable operation at an altitude of 1000m (which can be extended to 3500m). 

Technical parameter

Mechanical life: meet the M2 standard, and the electrical life reaches E2.

Arc extinguishing system: the opening and closing state is controlled by linkage between transmission rod and insulator, and auxiliary equipment such as fuse handcart and isolating handcart are equipped. 

The product adopts spring pneumatic operating mechanism, which can run stably without adjustment, and the phase-to-phase insulation performance is significantly improved, which is suitable for the adaptation of 1200mm, 1400mm and 1680mm wide switchgear.
