Type Test of 1kv waterproof insulation piercing connector 1.Mechanical test The mechanical test is checking the electrical continuity,shear heads and mechanical behaviour,mechanical strength of the main core and the mechanical strength of the tap cores. 2.Voltage test (6kV underwater) The IPC connectors shall be installed on minimum and maximum cross-section for main cores and minimum cross section for tap cores.tightening should be approximately one quarter turn during 1s to 3s. The assembly of modules and cores,maintained in a rigid and appropriate way,is placed at the bottom of a water tank.The water height is measured form the upper part of the module,and the cores are long enough out of the water to avoid flash over. The resistivity of the water shall be less than 200μm and its temperature is recorded for information. The voltage generator shall trip for a leakage of (10.0±0.5）mA After 30 min under the water,the voltage test is applied to the sample with a 6kV A.C voltage for 1 min. The A.C voltage is applied to a rate of approximately 1 kv/s.The satellite connector may be placed either vertically or horizontally. 3.Installation at low temperature The connector shall be loosely installed on the main core and on the tap core with stranded conductor,it is corresponding to the smallest and largest cross-section on the main core and to the largest cross section on the tap core. The connectors and the conductors are placed in an enclosure kept at -10 ℃. After 1h,while still inside the enclosure,the connector is tightened with a torque of 0.7 times the minimum torque. 4.Climatic ageing test 5.Corrosion test 6.Electrical ageing test 7.Visual inspection 8.Marking inspectionThe CONWELL insulated piercing connector is a revolutionary cable connection product that serves as a viable alternative to traditional junction boxes and T-connection boxes. Unlike conventional methods, this connector eliminates the need to cut off the main cable during installation. It enables branches to be easily created at any desired position along the cable without requiring special treatment for wires and clips. This results in a simple and fast operation, making the overall construction process more efficient.
