ZCW□-126/L Open-type Sulfur Hexafluoride Composite Apparatus

 Overview

 1.1ZCW□-126/L Open-type Sulfur Hexafluoride Composite Apparatus is a complete set of combination electrical apparatus that uses air as the external insulation SF6 gas as the arc extinguishing medium. The control and protection of 126kV transmission and distribution systems for three-phase AC can also be used in situations where circuit breakers and capacitor banks are connected. Suitable for urban substations, enterprise substations, and mountainous substations with tight land use. This product has the following characteristics:

 1) Organically combine circuit breakers, isolating switches, grounding switches, current transformers, SF6 voltage transformers, lightning arresters, busbars, and other components on a grounded steel structure bracket, resulting in a compact structure.  

 2) It occupies only 30% -50% of the space of the split type, and has the characteristics of saving land and reducing project costs.  

 3) The entire interval is prefabricated in the factory, assembled and debugged before leaving the factory, and transported to the installation site as a whole to shorten the installation cycle.  

 4) Adopting high-performance arc extinguishing chambers, SF6 voltage transformers, and composite insulator lightning arresters, with minimal maintenance and high reliability

 5) Prefabricated self-supporting busbars in partition factories do not require steel frames or insulators.  

 6) Flexible layout and can be used for various wiring methods.  

 1.2 ZCW10 is equipped with an optimized self powered arc extinguishing chamber and CT10-A spring operated mechanism.  

 1.3 ZCW10 complies with national standards GB1984-2003, GB11032-89, GB1985-2004, and meets the requirements of IEC 62271-100:2001, IEC 99-4, IEC 62271-102:2002, and IEC 60694:2002. All other components inside meet their respective national standard requirements.
