ZW8-12 series outdoor vacuum circuit breakers Applications and features : 1.ZW8-12 series outdoor vacuum circuit breakers used CT23-spring Chuneng style parade moving bodies, achievable electric Chuneng, electric hours, switch on, and can also achieve manually operated Chuneng hours, switch on. 2. Use of environmental conditions Environmental temperature : -30 ceiling +40t floor. C Altitude : "1000m Wind pressure : =700Pa (a wind 34m/s) Air filthy degree : III No recurrent violent shock Structure 1.ZW8 series switches composition For the three-phase structure of the overall total box-style Vacuum Miehu Room Spring parade moving bodies Insulation system Conductive circuit Boot, replace Sealed cases

2.ZW8 series switches feature According to user needs insulation can be installed 50/5,100/5,200/5,400/5,630/5 current transformer, a high-pressure pipe, insulation Silastic for composite insulation Built-in multi-tap transformer current use as a current protection As a double-winding currents transformer protection and the use of measurement If retrofitting voltage transformer, automatic coincidence signal controllers, automatic subparagraph controller achievable distribution automation and protection "4 Pity" (telemetry, tele-action, remote control, remote tune) function with a composite signal controllers (Elimination switch in flow). Can install separate switches Sales and delivery conditions With technological upgrading, product data, size and weight may change, Dingxin reservation changes. Check all the information carefully, to accurate, if printing error, if forgiven. Functional specification is a product of specific products. It orders Orders, users must provide the following technical information : 1, circuit breakers type, name and quantity. 2, rated current, rated short circuit operating currents. 3, operating methods, operating voltage. 4, compared with current transformer currents. 5, the use of occasions.
