Insulation rubber sheet introduction Insulation rubber sheet has good physical and mechanical properties, has excellent insulation performance, can work in a dry -35~+100℃ air environment with high dielectric coefficient requirements. Chinese Name: Insulating Rubber Sheet English Name: RUBBER SHEET Universal Voltage Level: 5-35KV Execution Standard: HG2949-1999 Color Classification: Red, Green, Black Insulation Rubber Sheet Features Passed 43KV test, normal work at 660V. Strong elasticity, excellent insulation performance, and shiny surface. It is widely used in substations, power plants, distribution rooms, laboratories and field live work. Uses and storage methods are suitable for the laying of workbenches and ground in electronic places, and the ground laying and installation of power stations and substations; it should be stored in a dry and ventilated environment, away from heat sources, and away from the ground and walls more than 20cm. Avoid being polluted by acids, alkalis and oils, and do not open air to avoid direct sunlight. Selection configuration table Insulation pads of different thicknesses should be selected in the use environment of different voltage levels.
