This series of products is widely used in automatic devices for reactive power compensation of outdoor installations on 10 kV lines.

This device consists of a high-voltage vacuum circuit breaker type ZW43-12Y, an integrated combined metering station and a prepayment meter control cabinet.

This series of 10 kV, 35 kV products is made using the method of complete vacuum filling with imported resin for external use and combines a voltage transformer and a current transformer in a single housing.

This product is intended for use in low-voltage distribution lines with a rated frequency of 50 Hz, transformer power 20-315 kVA, rated voltage 400 V and below for prepayment and metering control purposes.

The complete pole switch with the integration of primary and secondary equipment (ordinary pole type) complies with the requirements of the standardized design scheme set forth in Document No. 151 of the Equipment Department of the State Grid Corporation of China.

The complete pole switch with the integration of primary and secondary equipment (support type with deep integration) complies with the requirements of the standardized design scheme set out in Document No. 151 of the Equipment Department of the State Grid Corporation of China.

The pole switch with the integration of primary and secondary equipment ZW32-40.5 (measurement and control device, comprehensive fault isolation) (hereinafter referred to as the “switch”) is an outdoor distribution equipment used at a voltage of 40.5 kV, three-phase alternating current 50 Hz.

This series of high-voltage vacuum circuit breakers for outdoor installation has such advantages as safety and reliability in operation, ease of maintenance, and a long turnaround time.

The ZW7c-40.5 series outdoor high-voltage AC vacuum circuit breaker (hereinafter referred to as the “breaker”) is a high-voltage outdoor switching equipment of three-phase 50Hz alternating current.
