Wholesale TY-DFW-7A branch box Supplier, Factory

The TY-DFW-7A branch box uses molded components and a building block assembly structure to ensure high dimensional accuracy and convenient installation. The box adopts a fully insulated structure and does not require an additional grounding system. This feature is particularly important in environments where electrical safety is critical. Insulation not only protects internal components, but also improves the overall efficiency of the electrical system, ensuring that energy losses are minimized. The thermal insulation performance of the box combined with the specially designed ventilation structure can effectively prevent condensation and frost from forming inside, avoiding damage to electrical components.

Product Description

Product Overview

The TY series fiberglass cable branch box developed by Teyi Electric Co., Ltd. is suitable for power distribution and control of power, lighting and power distribution equipment in power systems with rated frequencies of 50, 60Hz and rated voltages of 380V (660V). It is suitable for various harsh environments, substations (stations), industrial and mining enterprises, and outdoor public places such as urban roads, garden residential areas, high-rise buildings, and airports. It is especially suitable for use in factories with corrosive gases such as petroleum and chemical industries, as well as places with high salt fog such as coastal areas and islands.

SMC fiberglass cable branch box is made of new high-performance materials, which has advantages that ordinary materials do not have, especially its environmental protection, beautiful appearance, no light pollution, which is in line with the trend of creating an energy-saving and environmentally friendly society advocated by today's society. The box has many advantages such as strong insulation, electrical strength, resistance to electrical tracking, aging resistance, chemical corrosion resistance, flame retardant insulation, good toughness, etc., and has very strong mechanical strength, the safety performance of metal boxes, safety performance and interchangeability, and is a product for today's urban and rural power grid transformation projects.

TY series low-voltage cable distribution (line) boxes, street lighting control boxes and other products are used in three-phase AC 380/220V, 50Hz, rated current 630A and below power systems, that is, for distribution and control of power distribution equipment, suitable for various types of transmission and distribution substations, industrial and mining chemical enterprises, urban and rural residential areas, multi-story buildings, airports, docks and other outdoor public places.

Box Structure and Features

The box components are made of fully insulating polymer composite materials (SMC) through high-temperature molding. The entire box is assembled by interlocking functional components with high manufacturing precision. Its structure is novel, compact and easy to assemble. It also has unique rainproof and ventilation design features.

The box has very good electrical performance, insulation index, dielectric strength, tracking resistance index, and aging resistance index are very good. Even in a very humid and harsh environment, there is almost no condensation, and it has very strong structural strength. With the safety performance of a metal box, even if the circuit inside the box fails or is damaged by external force, the box will not be electrified. It is particularly suitable for use in densely populated areas without protective nets.
