Electrical Insulation Material - Silicone Rubber Self Adhesive Tape

The insulating material described herein is an electrical insulating material. According to the national standard GB2900.5 insulation material is defined as: "The material used to make the device electrically insulated." This is the material that can stop the passage of current. Its resistivity is very high, usually in the range of 10 to 10 Ω·m. For example, in an electric motor, the insulation material around the conductor is isolated and insulated from the grounded stator core to ensure safe operation of the motor.


Insulation materials are one of the key factors that determine the technical and economic indicators of motors and electrical appliances. One of the important technical and economical indicators of the motor is the mass-to-power ratio, ie kg/kw. Decreasing the ratio has important significance for the motor. According to reports, from 1900 to 1967, the mass of a 1hp (0.75kW) motor was reduced from 40kg to 10kg, and it has now been reduced to a level of 6kg/kW. An important reason for this change is the use of highly heat-resistant insulating materials. Reducing the kg/kW value can save a lot of metal materials and reduce motor costs. If an A-class (105°C) motor is insulated with H-grade (180°C), the volume can be reduced by 30% to 50%, saving 20% of copper, 30% to 50% of silicon steel, and 25% of cast iron. Of course, using the same type of machine, with a higher temperature index insulation material, can increase power or extend the life of the motor. From the perspective of the cost of electrical and electronic products, the cost of insulating materials is about half, which explains the position and role of insulating materials in the electrical and electronic industries.
