Overview
ZW32 series outdoor high-voltage vacuum circuit breakers are outdoor high-voltage distribution devices with rated voltage of 12KV-36KV and three-phase AC of 50Hz.It is mainly used for opening and closing the load current, overload current, short circuit current in power...
Product Details
PRODUCTION INTRODUCTION
The circuit reclosers are recently-developed pole-mounted intelligent vacuum circuit reclosers of a new generation, which absorb the advanced domestic and foreign technologies adopted by our company. It is intelligent, energy-saving, environemntally-friendly and maintenance-free.
This product integrates such functions as control, protection, measurement, fault positioning, online monitoring and synchronous closing. With full functions and high digitalized and intelligent degree, it is a best choice for power distribution equipment network automation and intellectualization process.

ENVIRONMENT CONDITION
1. Ambient air temperature: -25°C~+40°C;
2. Altitude: no more than 2000m;
3. The ambient air may be polluted by dust, smoke, corrosive gases, steam or salt fog;
4. The wind speed does not exceed 34m/s;
5. Vibration or ground motion from the switchgear and control equipment is negligible;
6. If beyond the above normal use conditions, pls discuss with the manufacturer.
Our advantages:
Most parts are manufactured ourselves, like: frame, cabinet, permanent magnet mechanism, insulation part, control panel, etc. That means the process quality control is effectively controlled.
