China Suppliers TY-DFW Wall-Mounted Cable Branch Box for Outdoor Use in Factories and Substations
Product Overview
The TY series wall-mounted cable branch box developed by Teyi Electric Co., Ltd. is specially designed for 50/60Hz, 380V (660V) power systems and is mainly used for power distribution and control of power, lighting and distribution equipment. This product is suitable for outdoor places such as substations, industrial and mining enterprises, urban roads, residential areas, high-rise buildings and airports, especially for petrochemical plants with corrosive gases and coastal and island areas with high salt fog.
The wall-mounted cable branch box made of SMC's new high-performance material is environmentally friendly, beautiful, and light-free, which is in line with the concept of energy conservation and environmental protection. The product has excellent insulation, electrical strength, aging resistance, chemical corrosion resistance, and flame retardancy, and has both high-strength mechanical properties and the safety of the metal box. It is an ideal supporting equipment for urban and rural power grid transformation.
TY series wall-mounted cable branch boxes are suitable for three-phase AC power systems below 380/220V, 50Hz, and 630A. They can be widely used in various power distribution places such as substations, industrial and mining enterprises, residential areas, buildings, airports, and docks.
Box Structure
The box is made of fully insulating polymer composite material (SMC) and is formed by high-temperature molding. Each functional component is precisely assembled through an interlocking structure, with the characteristics of high manufacturing precision, novel and compact structure, convenient assembly, and integrated unique rainproof and ventilation design.
Its electrical performance is excellent, and its insulation index, dielectric strength, tracking resistance and aging resistance are outstanding. In extremely humid and harsh environments, the box hardly produces condensation, and the structural strength is extremely high. At the same time, it has the safety performance of a metal box: even if the internal circuit fails or is damaged by external forces, the box as a whole remains uncharged, which is especially suitable for crowded areas and places without protective nets.
Features
The product adopts a modular building block assembly structure, and the mold forming process ensures that the dimensions of each component are accurate, and the assembly is convenient and efficient. The box adopts a fully insulated design, with excellent electrical insulation performance, completely eliminating the need for a grounding system.
Innovative thermal insulation materials combined with scientific ventilation structure effectively prevent internal condensation and frost. Its special formula material has excellent chemical corrosion resistance, can resist weak acid, weak alkali, salt spray and rain erosion, and adds anti-ultraviolet ingredients to greatly improve the durability and service life of the product.
The fully sealed box is equipped with professional protection design, with a protection level of up to IP44/IP54. The internal components are reasonably arranged, and the electrical components are easy to install and operate. The product has both lightweight and high strength characteristics, excellent high temperature resistance and flame retardant performance, and the overall structure is stable and reliable.
The compact cabinet structure is matched with a streamlined appearance design. The naturally coordinated color scheme is both beautiful and avoids light pollution, perfectly integrating into various environments.
