SiHFC Cable for EMC-Sensitive High Temperature Connections
SiHFC cable is a screened silicone rubber cable designed for the connection of mobile electrical appliances in demanding environments. It is suitable for high ambient temperatures, low temperature conditions, and installations where electromagnetic compatibility is important. The cable uses silicone rubber insulation, a silicone rubber inner sheath, a tinned copper wire braid screen and a red silicone rubber outer sheath.
Key Features
- Screened construction: The TCWB tinned copper wire braid helps reduce electromagnetic interference in EMC-sensitive applications.
- High temperature resistance: Rated for fixed installation from -60°C to +180°C, supporting use in heat-exposed industrial environments.
- Flexible tinned copper conductor: Class 5 stranded tinned copper provides flexibility and stable conductivity for appliance and equipment connections.
- Silicone rubber insulation and sheath: Offers good flexibility and temperature performance compared with standard PVC cables.
- Resistance to industrial media: Insulation and sheath are resistant to most oils, greases, acids, lyes and oxidants.
- Multi core range: Available from 2 cores to 25 cores for different control, signal and power connection requirements.

Why Choose SiHFC Screened Silicone Cable
SiHFC cable is suitable when a standard multi core silicone cable is not enough and EMC protection is also required. Its tinned copper wire braid screen, silicone rubber insulation and silicone outer sheath make it a practical choice for equipment manufacturers, maintenance teams and industrial buyers working with high temperature, low temperature or interference-sensitive installations.
FAQ
What is SiHFC cable used for?
SiHFC cable is used for connecting mobile electrical appliances and equipment in high or low temperature environments, especially where screened cable construction is required for EMC-sensitive applications.
What is the difference between SiHFC and SiHF-J cable?
SiHFC cable includes an inner sheath and a tinned copper wire braid screen, while SiHF-J is an unscreened silicone cable. SiHFC is selected when electromagnetic interference protection is required.
What temperature can SiHFC Silicone 180 cable withstand?
The cable is rated for fixed installation from -60°C to +180°C, making it suitable for both heat-exposed and low temperature environments.
Is SiHFC cable resistant to oil and chemicals?
Yes. The product information states that the insulation and sheath are resistant to most oils, greases, acids, lyes and oxidants.
