Cable Branch Connection Box
(1)、Introduction
DFP-12/20 cable branch connection box series adopts good features of other products to design it.
According to12/20kV voltage grade,Exterior size is the same as 8.7/15kV voltage grade.it is suitable for 12/20kV series and used for 8.7/15kV series. Function is better than other products of same kind.
The product is widely used in city electric network such as industrial park and residential district and
exhibition hall of high environment demand.
Complete seal, complete insulation, complete screen, dustproof, corrosion resisting and flood prevention
(2)、Application environment condition
1、Altitude no more than 2000m;
2、Air temperture-35~55℃;
3、Air moisture≤95%;
4, Wind speed≤35m/s;
5、 without fierce shaking environment.
(3)、Products series

For example:
DFP-20/630/4-B indicates :20kV,630 4 branches screened separation cable connection box with arrester.
DFPK-10/630/6-X indicates :10kV,630A,6 branches screened separation cable terminal connection
box with load switch and power indicator.
(4)、Structure features
1、Many loops can be combined according to spot condition.
2、The case adopts high quality stainless steel with surface paint spray.
3、Common Type and the type with load switch can be chosen.
4、Screened separation connector and no screened can be chosen in the box.(cable terminal)
5, It can install lightening arrestor protection.
6、It can install power indicator and breakdown indicator.
7、Common color such as green. Other colors and steel color can be chosen.
