SIAF Cable for High Temperature Fixed Wiring
SIAF cable is a silicone rubber insulated cable developed for fixed wiring in applications where sustained heat resistance and dependable electrical performance are important. The product range also includes SIA cable with a solid conductor, giving buyers a choice between solid core and flexible core constructions for different installation requirements.
Key Features
- High temperature performance: Rated for fixed installations from -60°C to +180°C, making it suitable for both cold environments and heat-exposed industrial areas.
- Silicone rubber insulation: Provides reliable insulation performance where standard PVC cables may not be suitable because of continuous heat exposure.
- Solid and flexible conductor options: SIA uses a Class 1 solid copper conductor, while SIAF uses a Class 5 flexible copper conductor for easier routing in confined equipment spaces.
- Zero halogen design: Suitable for applications where halogen-free material selection is required.
- Wide size range: SIA is available from 0.5mm² to 10mm², while SIAF covers 0.25mm² to 300mm² for control, wiring and power applications.

FAQ
What is SIAF cable used for?
SIAF cable is used for fixed wiring in high temperature environments such as power plants, processing equipment, packaging machinery, refrigeration systems, foundries, aircraft construction and shipbuilding.
What is the difference between SIA and SIAF cable?
SIA cable uses a Class 1 solid copper conductor, while SIAF cable uses a Class 5 flexible copper conductor. SIA is typically selected for solid core fixed wiring, while SIAF is preferred where more installation flexibility is required.
What temperature can this silicone cable withstand?
The cable is rated for fixed installations from -60°C to +180°C, making it suitable for applications exposed to sustained heat or low temperature conditions.
Is this cable halogen-free?
Yes. The product information identifies the cable as zero halogen, which can be important for projects requiring safer material selection and reduced corrosive gas emission.
