I. Overview
The DFW-40.5 high-voltage cable branch box (switchgear) provides 10 standard combination forms, which can meet the application requirements of most 36-40.5kV distribution networks. The HXGN-40.5 compact switchgear can provide almost any combination of selected functional units.
The DFW-40.5 series has interfaces and user interfaces, providing a complete switch application solution for 36-40.5kV secondary distribution networks.
The stainless steel chamber of the DFW-40.5 series is filled with SF6 gas, completely sealing all live parts and switches, and isolating them from external connections. This fully sealed system ensures that internal switches and all live parts are not affected by external environmental changes, ensuring high reliability, personnel safety, and practical maintenance free.
Compliant with IEC62271-2003 "AC metal enclosed switchgear and control equipment with rated voltage above 1KV and below 52KV"
I. Product Features
This project is mainly aimed at indoor and outdoor SF6 box type fixed metal enclosed switchgear used in 40.5KV ring network power supply, wind power and new energy generation projects.
The switchgear series includes load switchgear, combination electrical cabinet, circuit breaker cabinet (CB Panel), busbar lifting cabinet, metering cabinet, and PT cabinet. In combination applications, each switchgear can be used in any combination.
