The concept of silicone wire
Silicone rubber, the insulation layer of silicone wire (SIF), has a wide operating temperature range of -110°C to 350°C. Compared with ordinary organic rubber, it has superior heat and cold resistance and is widely used.
In addition, due to its excellent voltage resistance, electrical insulation, volume resistance, arc resistance, flame retardancy and other characteristics, it is widely used in various fields.
Silicone rubber has extremely superior resistance to the main causes of aging of ordinary organic rubber, such as ultraviolet rays, radiation, ozone in the air, chemical resistance, steam resistance, antibacterial and antifungal resistance,
and also has the characteristics of being odorless, tasteless and non-toxic.Therefore, silicone wires are widely used in underground cables, various O-rings, ship wires, building window Gast and many other uses.
Analysis of uses according to the types of silicone wires
SRG-W (Silicone rubber wire for internal wiring of insulating devices)
is a heat-resistant wire with silicone rubber insulation layer and glass fiber braid reinforcement on the outside.
It has cold and heat resistance characteristics in the range of -60~200°C.
This wire is used in places that require flexibility between low and high temperatures, such as home appliances, residential facilities, office equipment, and automotive electronic parts.
KC-W (internal wiring of devices that require better flexibility than SRG-W)
is a heat-resistant wire insulated with silicone rubber, which has excellent flexibility and is used for high-voltage wires.
Application: lighting fixtures, heating equipment, electrical appliances, lighting cables, etc.
GB-W (Industrial Heater Connection Wiring)
This wire is used for connection wiring in high-temperature areas, such as wiring of metal pipe heaters, commercial cooking equipment, and other environments that generate ultra-high heat.
Muliti Cable (composite multi-core cable)
uses silicone rubber and Teflon insulated multi-core wires to combine into the required multiple strands, and then uses copper wire braiding, glass fiber braiding, aluminum tape braiding, etc. to design cables of various shapes.
This composite cable is widely used in lighting equipment wiring, various industrial machinery, heavy electrical equipment and other fields.

※ The above allowable current is the theoretical allowable current under normal temperature conditions, so temperature compensation is required in actual applications.
The safety factor should be 20% or more (actual application value = theoretical current value * 0.8)
