This article introduces the basis documents for the testing standards of insulation tools for live working, the testing items and standards for insulation tools at different voltage levels, and the testing cycle of live working tools
1. Experimental Items and Inspection Standards for Insulated Tools for Live Working
The testing of live working tools is the only reliable means of inspecting whether the tools are qualified. Even carefully designed tools must pass the test to make a conclusion on whether they are qualified or not.
Tools may cause or leave unexpected defects in various stages such as production, transportation, and storage. Most of these defects can only be exposed through testing
Test standards for insulation tools for live working: The test standards for insulation tools for live working are mainly based on GB 13398 "Hollow insulation pipes, foam filled insulation pipes, and solid insulation rods for live working", GB/T 13035 "Insulating ropes for live working", DL409 "Electric Power Safety Work Regulations", DL/T878 "Test Guidelines for insulation tools for live working", DI/T976 "Preventive Testing Regulations for Live Working Tools, Devices and Equipment" and "State Grid Corporation of China Electric Power Safety Work Regulations"
