DFT6-12(40.Cable Distribution Box - Reliable Power Supply Equipment from China Suppliers and Factory
Product Application
Distribution networks in urban industrial communities, residential areas, commercial centers, mining areas, airports, railways, wind power plants, switch stations, and large enterprises such as steel, petrochemicals, cement, and other occasions. It is particularly suitable for urban road and power grid renovation projects, which can greatly save investment in electrical equipment and cables.
Product Features
The cable distribution box is an outdoor type, with a fully insulated, fully sealed, and fully shielded structure that does not require insulation distance. It is also resistant to heavy pollution, condensation, and water flooding, meeting outdoor all-weather operating conditions.
Small footprint, easy to relocate, beautiful appearance, and easy to coordinate with the surrounding environment.
The box material is made of high-quality stainless steel plate and lined with anti-corrosion cedar board, which has strong corrosion resistance, durability, and a service life of 30 years.
The internal cabinet adopts miniaturized SF6 gas filling cabinet or environmentally friendly gas cabinet, and all high-voltage live parts of the switchgear are enclosed in an airtight box.
Adopting flood resistant touchable cable heads, which can withstand flood invasion and greatly ensure power supply reliability.
Easy to install distribution network automation, achieving primary and secondary integration.
The structure is flexible and can form distribution schemes ranging from simple to complex, meeting various configuration requirements in secondary substations and switching stations.
