Features of low-voltage cable branch box:
1. The box structure is divided into SMC composite material combination mode and metal plate production mode.
2. The box of SMC composite material combination mode is made of glass fiber reinforced polyester resin as a whole, and the box is a plate structure, which can be simply assembled with simple tools. The surface of SMC composite box is cast with strip
The edge has the function of preventing small advertisement pasting.
3. The metal box is made of stainless steel plate, aluminum coated zinc plate or ordinary steel plate. The box is formed by bending and spraying outdoor plastic powder. The structure is compact and the appearance is beautiful.
4. The prefabricated cable plug device is adopted, which has the excellent performance of full insulation, full sealing, full waterproof, maintenance free, safe and reliable. The cable plug devices have various varieties, complete specifications, serialized configurations, and convenient disassembly and assembly.
5. The cable branch box adopts the structure of component module assembly and frame assembly, and the bus and feeder are insulated and enclosed.
6. The incoming and outgoing lines shall be insulated closed disconnectors. The incoming and outgoing lines shall be plastic case circuit breakers. The incoming and outgoing lines shall be insulated closed disconnectors. The incoming and outgoing lines shall be knife fused switches
The incoming and outgoing lines of the strip switch (with fuse protection) have no switches, and the outgoing and outgoing lines are knife fuse switches. The incoming and outgoing lines are not equipped with switches.
7. A variety of branching methods, box types and installation methods are provided, and users can choose from flexible solutions
Select to meet the needs of distribution network and users.
Installation, use and precautions of low-voltage cable branch box:
1. Whether the operation method for the installation and connection of cable branch box and cable joint is correct, whether the installation process of cable head is familiar, and whether the sequence of the combination of components inside the cable branch box and cable joint parts is in accordance with the manufacturer
The service life and normal operation of the cable branch box will be directly affected if the installation specification is provided for operation.
2. Before the operation of the cable branch box, check whether the grounding wire of each branch cable is firmly connected with the grounding terminal of the box. At the same time, the box shell must be directly connected to the grounding grid or have an obvious grounding point.
3. After the installation of the cable branch box is completed, the cable components must be tested together according to the relevant test standards and conditions.
