Product Description

252kV Outdoor HV AC SF6 Circuit Breaker  For Distribution  Introduction

The outdoor high voltage SF6 VCB, designed for power distribution at 252kV, is a compact, integrated system that incorporates crucial elements. These elements encompass solid dielectric insulating rods, vacuum interrupters, current transformers, and voltage sensors. The VCB's operation is facilitated by either a permanent magnet drive or an electric motor drive.

The fusion of these elements engenders a unit characterized by simplicity and user-friendliness. This amalgamation ensures easy operation and offers design flexibility. Every component synergizes harmoniously with the others, guaranteeing efficient performance. Notably, even though the control unit is physically distinct, it seamlessly assimilates into the entirety of the VCB system, functioning as a unified entity.

In simpler terms:

The outdoor SF6 VCB, tailored for 252kV power distribution, is a compact unit that brings together vital elements. These comprise sturdy insulating rods, vacuum interrupters, current transformers, and voltage sensors. The VCB can be powered through a permanent magnet or electric motor drive.

The convergence of these parts results in a straightforward, adaptable unit that's easy to use and can be designed according to varying needs. Every piece collaborates seamlessly, ensuring efficient operation. Importantly, while the control unit maintains its separate identity, it smoothly integrates into the entire VCB setup, behaving as a single, unified apparatus.
