Detailed Description

Overview

ZW10(27)-12 outdoor high-voltage AC vacuum circuit breaker is a three-phase AC outdoor High-voltage Switchgear, mainly used in power distribution systems of rural power grids, urban power grids, mines, railways, and ports with a voltage level of 12kV and a rated frequency of 50Hz. It is particularly suitable for outdoor overhead lines to switch and protect the power grid by separating and combining load current, overload current, and short-circuit current.

Normal use conditions

◆ Ambient temperature from -40°C to +40°C;

◆ Altitude not exceeding 2000m, negotiate with the user for altitude above 2000m;

◆ Wind pressure not exceeding 700Pa (equivalent to wind speed 34m/s);

◆ Daily average relative temperature not exceeding 95%, monthly average not exceeding 90%;

◆ Air pollution level I;

◆ The surrounding air should not be obviously polluted by corrosive gases or flammable gases;

◆ No frequent severe vibration.
