Continuous-Flex High-Temperature Silicone Control Cable 0.6/1 kV

This continuous-flex high-temperature control cable combines Class 6 tinned-copper conductors, heat-resistant FEP core insulation and a flexible silicone outer sheath. It is engineered for cable tracks and moving industrial equipment operating continuously at temperatures up to +180°C, with short-term exposure up to +200°C.

Application
Construction
Technical Data
Dimensions
Packaging

Designed for control and auxiliary power circuits in continuously moving machinery exposed to extreme ambient temperatures.

Typical applications include:

Cable tracks in steel production and processing plants
Conveyor systems operating in high-temperature zones
Feeding lines for blast furnaces
Moving machinery installed near industrial furnaces
Heat-treatment and metal-processing equipment
Automated production systems exposed to radiant heat
High-temperature material-handling equipment
Industrial control circuits requiring continuous bending

The cable is intended for repeated bending in properly designed cable tracks. Continuous torsional movement requires a separately engineered and tested torsion-rated construction.

Common Questions

BEFORE YOU ORDER

For stocked configurations listed in the ordering table, MOQ is 100 metres per specification. Custom configurations — non-standard core counts, jacket colours, or special compounds — carry a 500 metre MOQ. Samples of 5–10 metres are available free of charge for qualification testing.

Use shielded (P or PP suffix) whenever the cable runs alongside servo drives, VFDs, or inverters, or when carrying encoder, sensor, or analogue signals. Unshielded is suitable for pure power distribution and simple on/off control lines. If in doubt, our engineering team can review your cabinet layout and advise — this is included with any quotation.

Yes. Send us the existing part number or a sample and we will produce a cross-reference specification with matching electrical, mechanical, and dimensional characteristics. Most cross-references are turned around within 3 working days, with a physical sample following within 7 days.

Standard shipments include the CE Declaration of Conformity, RoHS and REACH statements, and the batch test report. UL Recognition (UL 2464 / UL 20549) is available on request for North American projects — specify this at the quotation stage as it affects the material specification.

Standard configurations ship in 15 working days from order confirmation. Custom-engineered specifications typically require 20–25 working days, depending on compound availability. Rapid sampling for new specifications is 7 days. We will confirm the exact date in writing with your order acknowledgement.
