High Voltage Cable Branch Box (Outdoor Substation)

Category

High voltage cable branch box(outdoor substation)is widely used in 36KV,24KV ,12KV node connection of cable system. It is main electrical equipment for the cable to be assembled and separated from the outlet of the switchgear. Cable branch box adopts imported high grade rubber insulated tight insulation without naked live parts.

It is widely used in urban industrial district, residential district, commercial center, mining area, large scale enterprises such as steel, automobile, petroleum, chemical industry, cement, and other occasions, It is particularly suitable for urban power grid reconstruction project, which can greatly save the investment of electrical equipment and cables, and improve the reliability of power supply.

Product Highlights
  • High Voltage Cable Branch Box is designed for outdoor maintenance free operation, safe and reliable and its protection degree reaches IP33.
  • The underground branch connector is anti-flood.
  • This equipment complies with the requirements of standard IEC62271-200,IEC62271-100 etc.
