(F)DF series low-voltage cable branch box

The (F)DF series low-voltage cable branch box is designed for the characteristics of many user units and complex distribution in low-voltage power transmission and distribution systems. It can greatly increase the outgoing circuit, and improve the safety and reliability of electricity, at the same time to regulate the outdoor low-voltage distribution system management and maintenance of great help. It is especially suitable for three-phase or single-phase power transmission and distribution or single-phase lighting systems in public places such as urban streets, colleges and universities, high-end commercial districts, office buildings, high-end hotels, high-end villas, state agencies, residential quarters and high-rise buildings.

Product Parameters

Performance characteristics

(1) The overall volume of the low-voltage cable branch box and the installation area are reduced by 1/3 compared with similar products.

(2) The low-voltage cable branch box is simple to install and maintain, and there is no fire danger.

(3) The low-voltage cable branch box body can be made of SMC composite material, which has high arc resistance, spark resistance, high-strength mechanical properties, and long service life; it can also be made of metal material, compact structure, beautiful appearance, and sealing Good, safe and reliable, easy to use.

(4) The inlet and outlet switch can adopt strip fuse switch according to customer's requirements, which can connect, carry and break the normal load current, form obvious visible fracture, and can play overload and short circuit protection functions; Molded case circuit breaker can also be used, which has the functions of short circuit protection, overload long delay protection, isolation and safety protection.

(5) The busbar system adopts rectangular busbar made of T2 electrical copper and insulated with heat shrinkable sleeve. Enclosed bus system can also be adopted according to the requirements, and closed non-perforated bus hooking technology can be adopted to ensure the reliable contact of the original hooking.

(6) Considering that the charged body is closed, the cable branch box has the function of reliable electrical grounding during maintenance. Ensure the personal safety of maintenance personnel.
