Insulated safety 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 to ensure safe and reliable insulation. In the production process of insulating safety shoes, PU injection, Y bottom adhesion and molding methods are generally used. According to China's national standards, insulated safety 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 European standard can reach 18000V. Traditional insulating safety shoes are made of cloth-covered low-voltage insulating rubber soles, and there will be safety shoes or cotton safety shoes that can withstand 5000V and 15000V test voltages. In the treatment of the outsole of insulated safety 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 safety shoe. In the insulated safety shoes produced by a small number of domestic enterprises, all outsoles are made of insulating materials, so there is no need to distinguish between insulating and non-insulating layers by color. Low-voltage cloth-covered rubber-soled insulated safety shoes can be used by indoor electricians in dry working environments. The high-voltage insulating cloth-covered rubber-soled safety shoes are suitable for use when electric workers are working around and setting up wires, but the cloth surface must be kept dry. The fabric rubber-soled insulation strip is higher than the general rubber-soled insulation safety shoes, and it should be a material with good insulation properties. All rubber insulated safety shoes have test voltage products such as 5000v.6000v.10000v.15000V. This kind of all-rubber and all-rubber insulated safety shoes is a traditional auxiliary tool in the power sector. Because of its good electrical insulation performance, it is suitable for all kinds of electrical workers to wear except for climbing operations. The disadvantage is that the air permeability is poor, and when the shoes are worn for a long time, the inside of the shoes is damp and uncomfortable.
