 252KV SF6 Circuit Breaker

1. Type: SF6 Type

2. Mode: LW10B-252

3. General Description

    LW10B column type SF6 circit breaker is independently developed by us, including 252KV, 363KV and 550KV products, which are used for making and breaking normal current, fault current and changing over circuit, so as to realize the control and protection of power system.

    Each pole has one break, LW10B-363 and LW10B-550 consists of two breaks, whether including closing resistance or not is up to requirement. For all of these three kinds of products, each pole is equipped with a hydraulic operating mechanism, which can make single pole operation and/or three pole electrically gang operation.

    Complete and strict type tests have been done on the product, type test certificates were issued by CESI, Italy and KEMA.
