A high-quality China Garden Tools Motor manufacturers . The hand-held power tools used by electricians are used in a harsh environment, which requires constant movement, high vibration and high noise during use. The power cord is easily damaged by external forces such as dragging, friction or mechanical extrusion, which will damage the insulation strength and cause personal injury or death due to electric shock. To prevent accidents, hand-held power tools should be selected correctly.
1. Choose qualified products with "3C" certification;
2. In general occasions, class II products should be used. This class of equipment has double insulation and is relatively safe to use;
3. When working in a humid place or a place with good electrical conductivity, such as a metal frame, you should use Type Ⅱ or Type Ⅲ products;
4. For working in narrow places such as metal containers, pipelines, boilers, etc., Class III products should be used;
5. If it is necessary to use Class I products, other necessary safety measures should be taken in accordance with safety requirements, such as installation of leakage protectors, safety isolation transformers, etc.
