OPPC pole line hardware,pole line hardware Structure: a. joint box is made of forging aluminum alloy, anti-corrosion, high-mechanical, belong to non-magnetic, so decrease the loss of magnetic-lag and eddy current. b. joint box is mechanical sealed, operate easily, open repeat, simple maintained. c. for terminal splice closure, it can choose the below box which splice one time or the upper and the below box splice two times. The opening location of below box can choose side or bottom. Classify:According to the cable connection, there are middle joint box and terminal joint box.  Model No and mark: For instance: Within mechanical sealed 24 cores,110KV line OPPC terminal joint box’s mark: GC-JD 110/24 Mainly technical requirements 1 Usage circumstance 1.1 Ambient temperature:-40°C~+70°C 1.2 atmospheric pressure:70 kPa~106 kPa 1.3 insulated abutment anti-dirtiness grade:three grade 2 Usage life:25 years 3 Electricity Function 3.1insulation resistance With the 2500V megger to test the insulation resistance not less than 5000 trillion ohms 3.2 Withstand voltage intensity Insulated abutment make a test for 1min power frenquency AC breaking-down test not puncture.
