Outdoor Disconnectors

GPW4-12, 40.5(D)


Product description
Product Overview
  • GPW4-12, 40.5kV series outdoor high-voltage AC disconnectors is a new designed and manufactured based on the mature experience of domestic existing disconnectors' production and foreign advanced technology.

  • GPW4-12kV, 40.5kV series outdoor high-voltage AC disconnectors with single-pole structure, suitable for power systems with a frequency of 50Hz and a rated voltage of 12kV and 40.5kV. It is used as a circuit breaker when there is voltage and no load. The antipollution disconnectors can meet the requirements of users in heavily polluted areas, and can effectively solve the pollution flashover problem that occurs during the operation of the disconnectors.
