Application fit

Is SiHFC right for your machine?

Specify SiHFC where control, sensor, or drive interconnections run through high-ambient zones up to +180 °C and simultaneously require 360° braided copper EMC screening.

Furnace, kiln & high-temp zone

Suitable

Silicone rubber cores and outer jacket remain elastic from -60 °C to +180 °C around furnaces, steelmaking lines, and glass lehrs.

VFD inverter to AC motor screened feeder

Suitable

Dense tinned copper braid screen (≥ 85 % coverage) suppresses electromagnetic interference on hot-zone instrumentation and servo drives.

Fixed installation

Suitable

Suitable for fixed cable trays, conduits, and open machine frames in foundries, coking plants, and cement works.

Motorised monospiral reel

Not suitable

Silicone elastomer has lower tear resistance than polychloroprene or PUR; do not use on high-tension motorized crane reels.

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

How should the tinned copper braid screen on SiHFC be grounded for best EMC performance?
Terminate the tinned copper braid 360° inside a nickel-plated brass EMC cable gland at the control cabinet entry rather than twisting it into a long pigtail. Full-circumference clamping maintains low transfer impedance at high frequencies.
Why must silicone cables like SiHFC be installed in ventilated raceways above +100 °C?
When silicone elastomers are hermetically sealed in unventilated conduits above +100 °C in the absence of air, siloxane hydrolysis reduces mechanical elasticity prematurely. Open cable trays or ventilated ducts preserve the full +180 °C thermal rating.
What happens to SiHFC insulation if exposed to open flame?
In addition to passing IEC 60332-1-2 flame retardance and IEC 60754 halogen-free tests, combusted silicone rubber leaves behind a non-conductive silicon dioxide (SiO2) ceramic ash around the cores that helps prevent immediate short circuits.
When should I choose SRG-K instead of SiHFC?
Choose SiHFC when electromagnetic compatibility (EMC) copper braid shielding is required. If the primary hazard is mechanical abrasion or hot metal spatter without EMI noise, choose SRG-K with its outer varnished fibreglass braid.
