IntroductionZW8-12YZD series AC high voltage outdoor prepay controlling device. Applied in the high voltage electrical system as prepay meter or automatic recloser of automation distribution net , AC50Hz, 6~12KV
Packing and shipping
Consist of metering current transformer, voltage transformer, vacuum circuit breaker, arrester, control devices. Metering methods include 3 phases 3 wires type or 3 phases 4 wires type
Control Chamber: Prepay energy meter is installed inside, with the functions of automatic transmission, data process, display ,save , alarm, automatic break. With the controller of anti-electricity stealing software,can realize electricity security effectively and avoid of electricity arrear.
The cabinet is the stainless steel floor structure, once cable inlet and outlet wiring, convenient for installment, small volume. Application surrounding
