Product Introduction

Production Introduction

Overview:

ZW30-40.5 Outdoor Vacuum Circuit Breaker is a three-phase AC 50Hz outdoor high voltage electrical equipment, with simple structure, small size, high reliability, easy installation, low noise and other characteristics, used for the division of rated current, fault current or conversion line.

The ZW30-40.5 Outdoor Vacuum Circuit Breaker is equipped with CT17-IV.B spring operation mechanism, and can also be attached to an external current transformer (referred to as CT), which can carry out three-pole splitter fast automatic reclosing operation, which can be applied to frequent operation occasions to realize the measurement, protection, control and operation of the transmission and transformation system.

Advantage:

1. The use of high-performance vacuum bubbles can meet all terminal short circuits, disconnect out of step, out-of-phase ground faults and cable charging current;

2. The rated short-circuit current can be turned off 30 times in a row;

3. The Vacuum < 1.33X10-3Pa;

4. The insulation tie rod material is more reliable with epoxy glass cloth laminate, and the joints are connected by rivets.

5. Long mechanical life, up to 10,000 times, reliable action, frequent operation, low noise;

Common models:
