Screened Continuous-Flex High-Temperature Silicone Control Cable 0.6/1 kV
This screened high-temperature control cable is designed for continuous movement in cable tracks exposed to extreme ambient temperatures. It combines Class 6 tinned-copper conductors, FEP core insulation, an overall tinned-copper braid and a flexible silicone outer sheath for dependable control transmission and electromagnetic interference protection at temperatures up to +180°C.
Key Highlights
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.
Recommended for continuously moving control and auxiliary power circuits where high temperatures and electromagnetic interference occur together.
Typical applications include:
- Cable tracks in steel mills and metal-processing plants
- Conveyor systems operating near furnaces
- Blast-furnace feeding lines
- Heat-treatment and casting equipment
- Moving machinery installed near motors and electrical drives
- Automated production equipment in electrically noisy environments
- High-temperature material-handling systems
- Control circuits requiring electromagnetic shielding
- Machinery exposed to sustained radiant heat
The overall tinned-copper braid helps reduce electromagnetic interference entering or leaving the cable. Final screening performance depends on braid coverage, termination method, grounding and installation conditions.

THE FACTORY
BEHIND EVERY METER
Founded in 2007 in Foshan, Guangdong, Hulk Electric has grown from a regional producer into a globally recognised manufacturer of customised industrial cable solutions. Our 10,000㎡ facility runs on Toyota Production System lean principles, operated by 150+ skilled professionals producing over 300,000 metres every month.
Every cable you see on this page — including the HK-TRVV series — is engineered, extruded, tested, and shipped from that single facility. No trading company sits between you and the extrusion line.
Source Factory
Direct manufacturer — no middlemen, no markups. You deal with the engineers who run the line.
Deep Customization
Conductor, shielding, jacket compound, colour coding, certification — built to your exact spec.
7-Day Sampling
Rapid samples for new specifications. 15-day lead time on standard production orders.
Global Compliance
35+ certifications covering UL, CE, TÜV, IEC, RoHS and REACH for every major market.
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.
