EC Insulators Silicone rubber and silicone composite insulating technologies are increasingly the materials of choice for electrical power grids because they offer high mechanical and insulation properties, ensure heat and fire resistance and can be used for a wide range of cabling applications in various sectors: utilities, construction, railways, urban lighting, rapid electrical vehicle (EV) charging stations, etc
1. Features of Silicone Rubber
Heat and cold resistance
Since silicone rubber has high bond energy and good chemical stability, its heat resistance is better than that of organic polymers. Furthermore, since the intermolecular interaction force is weak, the glass transition temperature is low and the cold resistance is good. Therefore, its characteristics will not change when used in any area on the earth.
Waterproof
Since the surface of polysiloxane is a methyl group, it is hydrophobic and can be used for waterproofing.
Electrical performance
The number of carbon atoms in the silicone rubber molecule is less than that of organic polymers, so its arc resistance and leakage resistance are very good. In addition, even if burned, insulating silicon is formed, so it has excellent electrical insulation.
Permanent deformation
The permanent set characteristics (permanent elongation and compression set) of silicone rubber at room temperature/high temperature are better than those of organic polymers.
2. Classification of Silicone Rubber
According to the characteristics before vulcanization, silicone rubber can be divided into two types: solid and liquid. According to the vulcanization mechanism, it can also be divided into three types: peroxide vulcanization, addition reaction vulcanization, and condensation reaction vulcanization. The difference between solid and liquid silicone rubber is the molecular weight of polysiloxane. Solid silicone rubber can be vulcanized by anyone of peroxide vulcanization and addition reaction, usually called high temperature vulcanized rubber (HTV) and heat vulcanized rubber (HCR). Although the liquid silicone rubber material vulcanized by addition reaction can be vulcanized at room temperature, it is called liquid silicone rubber (LSR), low temperature vulcanized rubber (LTV) and two-component room temperature vulcanized rubber (RTV) due to the different molding methods and vulcanization temperatures. ).
