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.
