Product Description

Product Overview

ZW7-40.5 outdoor high-voltage Ac vacuum circuit breaker is athree-phase Ac current transformer with a rated voltage of 40.5kV, 50Hzand an external outdoor power distribution device. lt is mainly used toopen and dose the load current, overload current and short circuit currentin the power system of the distribution network. lt is suitable for protectionand control in substations and power distribution systems of industrial andmining enterprises, suitable for rural power grids and frequently operatedplaces, and especially suitable for the needs of urban and rural power aridtransformation.

Working Environment

1. Ambient air temperature: upper limit +40℃, lower limit -30℃ (general 
area), -40℃ (alpine area); 
2. Altitude: ≤ 1000m (if the altitude increases, the rated insulation level 
will increase accordingly); 
3. Wind pressure: no more than 700Pa (equivalent to wind speed 34m/s); 
4. Earthquake intensity: no more than 8 degrees; 
5. Pollution level: Grade IV; 
6. Maximum daily temperature difference: no more than 25℃
