What is the silicone rubber insulated power cable?
Silicone rubber insulated power cable is a kind of special cable in low voltage power cable. The product replaces polyvinyl chloride with cross linked polyethylene as silicone rubber, which changes the product's characteristics.
The rubber cables are mainly applicable to power transmission lines with fixed rated voltage of 0.6/1KV and below, connection cables for mobile electrical appliances, and transmission and distribution lines that require high temperature resistance, corrosion resistance, wear resistance and softness. The products have heat-resistant radiation, cold resistance, and resistance Features such as acid-alkali, corrosive gas, waterproof, soft cable structure, easy installation, stable electrical performance under high temperature (high cold) environment, outstanding anti-aging performance, long service life, and can be widely used in metallurgy, electric power, petrochemical, electronics, automotive Manufacturing and other industries.
The main performance characteristics of silicone rubber insulated power cable as following:
1. The salient feature of silicone rubber is its high temperature stability. Although the strength of silicone rubber at room temperature is only half of that of natural rubber or some synthetic rubber, silicone rubber can still maintain a certain degree of flexibility at temperatures above 200°C. , Resilience and surface hardness, and no significant changes in mechanical properties;
2. Low temperature performance The glass transition temperature of silicone rubber is generally -70~-50°C, and the special formula can reach -100°C, indicating its excellent low temperature performance;
3. Si-O-Si bonds in silicone rubber are very stable to oxygen, ozone and ultraviolet rays, and have excellent weather resistance without any additives.
4, silicone rubber has excellent insulation properties, corona resistance and arc resistance is also very good;
5. The physical and mechanical properties of silicone rubber at room temperature are worse than that of general rubber. However, its physical and mechanical properties are superior to those of general rubber at high temperatures of 150°C and low temperatures of -50°C.
6, silicone rubber has a medium oil, solvent resistance;
7, gas permeability. At room temperature, the permeability of silicone rubber to air, nitrogen, oxygen, carbon dioxide and other gases is 30-50 times higher than natural rubber.
And for this silicone rubber insulated power cable, Changfeng Cable adopt the high quality non-toxic, odorless, odorless silicone rubber material as the insulation, besides that the material can meet the insulation resistance, good voltage resistance, good breakdown resistance, and also meet the halogen-free low smoke environmental performance requirements to ensure the safety and security when using. Of course, we ZMS Cable can customize the product as the mobile power cable with very high customization flexibility according to your requirements, it can also be customized with silicone rubber insulated power cable with armored structure that can withstand certain mechanical stress to satisfy you well.
