DFT6 12 Series Cable Branch Box

DFT6 12 Series Cable Branch Box

 DFT6-12 series cable branch box is a new power supply equipment that we design for coordinating 10kV's power network cable system. It is suitable at the cable node place in 10kV's system, and what It is as the electric energy accepts and distributing. This series cable branch box has unique structure and beautiful appearance, it especially is suitable widely at the place that small build-up area and higher requirement such as city street, residence area, high-rise, airport and wharf, etc.
     The cable branch box is the transfer station that cable conveyed the electric energy, and is used in outdoor with the cable circuit to connect and breakout, branch and continues or changes.

Product features :
      a. Join method is simple and reliable and it is convenient to install.
      b. Full insulation and the structure is completely seals up, exempts maintenance and fight a flood water.
      c. Once only few investment, and can save the investment of switch apparatus and cable.
      d. Small cover area and is easy to coordinate surround environment.
