Safety tools can be divided into two categories: insulated safety equipment and general protective safety equipment. Insulated safety equipment is divided into two categories: basic safety equipment and auxiliary safety equipment.
Electrical insulation tools and safety protection tools are divided into two departments according to their functions and roles:
1. Basic insulation safety tools;
It refers to the insulation strength of safety tools that can withstand working voltage and directly operate high-voltage electrical equipment, as well as tools that come into contact or may come into contact with live objects. Such as capacitor tester, insulation rod, insulation partition, insulation cover, phase detector, portable short-circuit grounding wire, personal safety grounding wire, etc.
2. Auxiliary insulation safety tools;
It refers to the effect that the insulation strength cannot withstand the working voltage. Only used to enhance the safety of basic insulation safety tools to prevent injury to operators caused by contact voltage, step voltage, leakage current, and arc. The safety industrial uses belonging to this category include: insulated gloves, insulated boots (shoes), insulated rubber pads, insulated tables, insulated products, etc.
