Wire and cable y
Y refers to rubber insulation. Insulated rubber products are rubber products with high elasticity but difficult to conduct electricity, which are made of rubber as the main material and added with relevant additives. They can usually be referred to as insulating rubber products.
Application field of cable y
Due to the high elasticity and poor conductivity of insulating rubber products, they have been increasingly used to replace traditional insulating materials such as ceramics, glass, wood, pure water, and are widely used in the electrical insulation protection of magnetic fields, electrical appliances, and circuits. Natural rubber and most synthetic rubber have good physical and mechanical properties and electrical properties at the same time. They are often used as electrical insulators for labor protection, insulating gloves, insulating carpets, circuit wiring plugs, rubber insulating products for television sets, electrical touch switch insulating pieces, high-voltage line insulators, shock insulation pads on cars, battery rubber shells The insulating sheath of wires and cables and a variety of insulating rubber accessories used in national defense and military industry.
Performance requirements for insulating rubber
1. Volume insulation resistance Volume insulation resistance is a very important index to measure the electrical properties of insulating materials. 2. Breakdown voltage The breakdown voltage per unit thickness of rubber insulator is an indispensable technical parameter to measure the electrical insulation performance of insulating rubber products. 3. Dielectric constant Dielectric constant is an electrical parameter to measure the conductivity. The greater the dielectric constant, the more current it passes through, and the worse its electrical insulation performance. 4. Power factor Power factor is an index to measure the heat output and heat loss of an insulator when it works normally. Generally, when the medium has large heat generation and heat loss, the power factor of the medium is large and its insulation performance is poor.
