SiHF-J Cable for High Temperature Appliance Connections
SiHF-J cable is a 300/500V multi core silicone rubber cable used for the connection of electrical appliances in demanding temperature conditions. It is suitable for fixed or limited-flexing installations without mechanical stress, including high temperature areas such as steelworks and low temperature environments where ordinary PVC cables may become unsuitable.
Key Features
- Wide temperature range: Designed for fixed installation from -60°C to +180°C, making it suitable for both cold and high heat environments.
- Silicone rubber insulation and sheath: Provides good thermal stability and flexibility compared with standard PVC appliance cables.
- Class 5 tinned copper conductor: Flexible stranded tinned copper supports easier routing and reliable conductivity in equipment connections.
- Resistance to industrial media: Insulation and sheath are resistant to most oils, acids, lyes and oxidants.
- Multi core construction: Available from 3 cores to 25 cores for appliance wiring, control connections and equipment installation.
- Flame retardant performance: Flame retardant according to IEC 60332-1-2.

FAQ
What is SiHF-J cable used for?
SiHF-J cable is used for connecting electrical appliances and equipment in high temperature or low temperature environments, especially where the cable is not exposed to mechanical stress.
What temperature can SiHF-J Silicone 180 cable withstand?
The cable is rated for fixed installation from -60°C to +180°C, making it suitable for both cold environments and heat-exposed industrial areas.
Is this cable resistant to oil and chemicals?
Yes. The product information states that the silicone rubber insulation and sheath are resistant to most oils, acids, lyes and oxidants.
What is the difference between SiHF-J and ordinary PVC appliance cable?
SiHF-J uses silicone rubber insulation and sheath, allowing it to perform in higher and lower temperature environments than standard PVC appliance cables. It is also designed for industrial conditions where heat and chemical exposure may be present.
