Insulated shoes require the outsole to be made of insulating rubber material, and there should be no metal parts or abnormal electrical parts. If necessary, metal parts should be insulated. Ensure safe and reliable insulation.
In the production process of insulating shoes, rubber or PU injection, Y bottom adhesion and molding are generally used.
According to China’s national standard, insulated shoes have a test voltage of 6000V, which is suitable for electrical workers in dry indoor environments. Because of their good air permeability, they are popular with wearers. But now abroad, the highest European standard can reach 18000V.
Traditional insulating shoe products are fabric-surfaced low-voltage insulating rubber soles, and there are safety shoes or cotton safety shoes that can withstand 5000V and 15000V test voltages.
In the treatment of the outsole of insulated shoes, many products are covered with a wear-resistant layer outside the insulating layer, which is distinguished by color. This is a general distinction. After wearing for a period of time, when the wear-resistant layer is worn out and the insulating layer is exposed, it means that the shoe cannot be used as an insulating shoe.
In the insulated shoes produced by a small number of domestic enterprises, all the outsoles are made of insulating materials, so there is no need to distinguish between insulating and non-insulating layers by color.
Low-voltage rubber-soled insulated shoes can be used by indoor electricians in dry working environments. High-voltage insulating cloth-covered rubber shoes are suitable for use when electric workers are working around and laying wires, but the cloth surface must be kept dry. The cloth-covered rubber-soled insulation strip is higher than the general rubber-soled insulation safety shoes, and it should be a material with good insulation performance.
