Insulating rubber sheet introduction
Insulating rubber sheets, also known as insulating blankets, insulating mats, insulating sheets, insulating pads, insulating rubber pads, etc., have large volume resistivity and resistance to electrical breakdown. Mesa or floor insulation for work places such as power distribution. Physical and mechanical properties are good, with excellent insulation properties, can work in the environment of dry -35 ~ 100 °C air requirements for high dielectric constant. Through the 43KV test, it works normally at 660V . Strong elasticity, excellent insulation properties , shiny surface.
Insulation rubber sheet features
Physical and mechanical properties are good, with excellent insulation properties, can work in a dry -35 ~ +100 °C air medium demand high working environment. Through the 43KV test, it works normally at 660V. Strong elasticity, superior insulation properties, shiny surface. Widely used in substations, power plants, power distribution rooms, laboratories, and field live work.
Uses and storage methods
It is suitable for the laying of worktables and grounds for electronic sites, laying and installation of grounds for power stations and substations;
Should be stored in a dry and ventilated environment, away from heat sources, away from the ground [and wall more than 20cm. Avoid contamination with acids, alkalis, and oils. Do not expose it outdoors to direct sunlight.
Selection configuration table
The use of different voltage levels of the environment should use different thickness of insulating plastic sheet.
