Insulation insulation level of safety shoes

Insulation, also is to use non-conductive material will charged body isolation or wrapped, to get an electric shock protection of a security measure. A good insulating material is a good way to prevent electric shock of human body is the most basic and the most reliable method. The insulation safety shoes is to protect your feet don't get an electric shock caused by electric current contact. But if you use the insulation level is inconsistent with electricity, insulation material breakdown and may be losing its insulation performance, it would be completely lost its electrical insulation. So for the sake of your safety you chooses the insulation of the safety shoes must be made to match the voltage level. Therefore need to use the insulation safety shoes, first understand the insulation class. Temperature rating of the insulation: A grade E B grade levels F H C N R level allows the highest temperature: 105 120 130 155 180 200 220 240 ( ℃) Winding temperature rise limit: 60, 75, 80, 105, 125, 135, 150, 170 ( K） The performance of the reference temperature: 80 95 100 120 145 155 170 190 ( ℃)
