GBT3048.7 Overhead Cable Electric trace resistance tester
Standards met:
GB_T3048.7-2007 Wire and cable Electrical performance test method_part 07: electric trace resistance test
Product Overview:
Leakage trace: under specified test conditions, solid Insulating material Under the combined action of electric field and electrolyte, the conductive path gradually formed on its surface is called leakage trace.
Electric trace: the process of forming electric leakage trace is electric trace.
The main test principle of the electric trace resistance tester for wires and cables is to output a certain high voltage through the high voltage source. Under the combined action of high voltage and electrolyte, the sample can judge whether the current at the sample's ground terminal exceeds 1A in several cycles, so as to judge the insulation performance of solid insulating materials.
The electric trace resistance tester for wires and cables produced by Shenzhen Sungrow Yueda Technology Co., Ltd. is currently the relatively domestic electric trace resistance tester for wires and cables.

04. Voltage test accuracy:<2%
05. Output current at HV side: ＞ 1A
06. High voltage side output current:>250MA, larger voltage drop<5%
07. Current measurement accuracy: ＜ 1%
08. Spray range:>1M
09. Distance from the sprinkler to the ground: ＞ 600CM
10. Distance between nozzle and sample:>500CM
11. The axis of the nozzle is 45 degrees from the axis of the sample
