■ using the outdoor hydrophobic solid epoxy resin which can enhance anticorrosion and ageing resistance of the breaker especially in the heavy pollution environments, the Pole and current transformer be insulated seperately by APG process

■ Equipped with permanent magnetic actuator or Miniaturized spring machanism. Direct-acting transmission, less

components, high reliability.

■ HVEW can be equipped with disconnector, and have reliable mechanical interlocking device.

■ With flexible Intelligent controller, HVEW can be applied to relizing distribution network automation functions of

the boundaries circuit breakers, reclosers and section switches, etc.
