Product Description
Product Overview
The 0.4 kV low-voltage cable distribution box is a complementary piece of equipment for urban grid cableization upgrades, primarily used in public power grids. Based on the needs of transmission and distribution networks as well as end-users, it offers a variety of wiring configurations, enclosure types, and installation methods, allowing users to easily select the most suitable solution from a flexible and versatile range of options. In the construction and renovation of distribution networks, it serves as an ideal replacement for overhead feeders, providing reliable support. It is widely employed in three-phase low-voltage power transmission and distribution systems in outdoor public spaces such as substations and distribution stations, industrial and mining enterprises, streetsides, garden residential communities, high‑rise buildings, airports, and various construction and renovation projects—acting as a complete, standardized device for distributing electrical energy via cables to other users or equipment.
Product Model and Meaning

Main Features
1. The equipment can be installed either floor‑mounted or wall‑mounted, and is suitable for both indoor and outdoor environments, meeting the needs of most application scenarios.
2. The enclosure of the distribution box is made of stainless steel, boasting a sleek and aesthetically pleasing design. The box’s structural design meets all relevant standards and takes into account the potential impacts of both indoor and outdoor environments on the equipment, effectively delivering “three protections and one ventilation” (namely, protection against rain and snow, corrosion resistance, prevention of small insects from entering, and efficient ventilation and heat dissipation). It also features excellent corrosion‑resistance performance. The cable entry and exit points are equipped with an adequate number of cable protection sleeves and cable clamps.
3. The equipment features a complete primary circuit design, allowing users to flexibly select components such as knife switches, knife-fuse switches, and circuit breakers as incoming and outgoing line devices according to their needs.
4. Fully insulated and fully sealed design for reliable performance;
5. Dustproof, fire‑resistant, corrosion‑resistant, and maintenance‑free—suitable for both outdoor use and submersion in water, making it ideal for harsh environments.
6. The combination is extremely flexible, meeting a variety of wiring requirements.
