Insulating rubber sheet
I. Electrical performance
Excellent insulation
Insulating rubber sheet can effectively prevent the passage of current, and its insulation performance is one of its most important characteristics. It has a high resistivity and can withstand a certain voltage without conducting electricity. For example, in some low-voltage electrical equipment installation environments, such as laying insulating rubber sheets at the bottom of the distribution cabinet, it can prevent operators from accidentally getting electric shocks. Generally speaking, the insulation resistance of qualified insulating rubber sheets can reach very high values, such as 10^8 - 10^12Ω, which is enough to meet the basic requirements of most industrial and civil electrical safety.
Good voltage resistance
It can withstand voltages within a certain range without being broken down. Insulating rubber sheets of different thicknesses and quality grades have different voltage resistance indicators. For example, an insulating rubber sheet with a thickness of 5mm may have a voltage resistance of about 10kV. This allows it to be used as an insulating protective material in some substations, distribution rooms and other places, and can provide reliable insulation protection for operators even when voltage fluctuations occur in the equipment.
II. Physical properties
Good elasticity and flexibility
Insulating rubber sheets are elastic and can buffer external impact forces to a certain extent. For example, in some electrical work areas where people need to walk, it can reduce the impact of people's footsteps on the ground, and it can also act as a buffer when objects fall on it. Its flexibility also makes it easy to lay on various shapes of ground or equipment surfaces. For example, at the bottom of some irregularly shaped electrical control cabinets, the insulating rubber sheet can fit well and provide comprehensive insulation protection.
Anti-slip performance
The surface usually has a certain texture, which can increase friction and prevent people from slipping. In some humid or oily electrical working environments, anti-slip performance is particularly important. For example, in the motor room of a factory, since the equipment may leak lubricating oil, laying insulating rubber sheets can reduce the risk of workers slipping and falling, while ensuring insulation safety.
3. Chemical properties
Chemical corrosion resistance
It has a certain tolerance to many chemicals. It can resist the erosion of some common chemicals such as acids and alkalis. For example, in the electrical workshops of some chemical companies, there may be a small amount of acidic or alkaline gas and liquid leakage. The insulating rubber sheet can resist the corrosion of these chemicals to a certain extent, extend its service life, and continue to maintain its insulation performance.
Aging resistance
It can resist aging caused by natural environmental factors (such as ultraviolet rays, oxygen, etc.) and working environmental factors (such as temperature changes, chemicals, etc.) during long-term use. Generally speaking, high-quality insulating rubber sheets can be used for many years in normal indoor environments without significant performance degradation. For example, in ordinary power distribution rooms, even after years of use, as long as they are properly maintained, the insulating rubber sheets can still effectively play an insulating and protective role.
