ZW20 intelligent high-voltage vacuum Circuit Breaker,also known as outdoor column vacuum switch,the insulation medium is vacuum interrupter and SF6 gas,it is an improved product of ZW20 column Vacuum Circuit Breaker.The spring operating Mechanism of the column vacuum circuit breaker has been miniaturized and its performance is more stable and reliable.ZW20 vacuum circuit breaker adopts direct chain main drive and multi-stage tripping system.The operation is more reliable and stable than traditional domestic devices,which has lower resistance and lower temperature rise.

Model description

Product features

1.Flexible and convenient operation:This product can be used for electric energy storage.Electric opening and closing,manual energy storage,and can operate with remote control in close distance;excellent opening and closing performance,and opening and closing short circuit current 25kA up to 30 times.

2.Low operating power and high reliability:It is the newly designed miniaturized electric spring mechanism.The number of components and the rated power of the energy storage motor(about 40W)have been reduced to the lowest level.

3.Flexible installation method:it can be hoisted on the column or installed on the seat.

4.Maintenance free:The circuit breaker main circuit,secondary components,operating mechanism is sealed in SF6 gas(zero gauge pressure),which is not affected by external environment and it is stable,reliable&maintenance-free.

5.Reliable sealing performance:Adopts mature sealing structure technology with reliable sealing performance.

6.Good insulation performance of inlet and outlet wires:Silicone rubber casing is used to make the sufficient insulation distance between terminal connectors,and with good external insulation performance.

7.Safe usage:The explosion-proof device is installed on the top of the cabinet,there will be no leakage and overflow of high temperature gas or objects over 10 mm even if there is an accident of internal fault,.

8."Four remote controls"function:It can be matched with intelligent controller to realize remote control,remote measurement,remote communication and remote adjustment.
