ZCW10-40.5L Type Outdoor Enclosed Combined Electrical Apparatus

 Overview

ZCW10-40.5L Type Outdoor Enclosed Combined Electrical Apparatus is a complete set of combination electrical appliances that use air as the external insulation SF6 gas as the arc extinguishing medium. The control and protection of 72.5 KV transmission and distribution systems for three-phase AC can also be used for connecting circuit breakers and opening and closing capacitor banks. Suitable for urban substations, enterprise substations, and mountainous substations with tight land use.

 Structural Characteristics

 The circuit breaker is an outdoor small floor tank structure, equipped with a CT35 spring operated mechanism; The mechanism is installed in conjunction with the main body, with simple installation, convenient debugging, reliable operation, and suitable for frequent operation; The institution has a lifespan of over 10000 times;

 Adopting a compressed air arc extinguishing structure, the breaking capacity is particularly strong, with a cumulative breaking of 12 times at 40kA, setting a record for the highest in China;

 Reliable sealing performance Using sealing gaskets, the dynamic seal adopts a "V" - shaped sealing ring with spring pressure compensation structure, and the secondary wiring board of the transformer is matched by a joint venture enterprise, with an annual air leakage rate of less than 0.5%;

 The internal current transformer is made of microcrystalline alloy with high magnetic permeability, with an accuracy level of 0.2 or 0.2 seconds. According to user needs, 12 transformers can be attached. Suitable for a 50 kilometer long unloaded line without reignition.
