High-Temperature Halogen-Free Single Conductor Cable 220°C – Silver-Plated Copper
This 300/500 V high-temperature halogen-free single conductor cable features a fine-stranded, silver-plated Class 5 copper conductor for reliable performance and good solderability at temperatures up to +220°C. It is designed for protected internal wiring that requires heat resistance, flexibility, flame-retardant performance and low corrosive gas emission.
Key Highlights
Up to +220°C temperature resistance · Silver-plated Class 5 copper conductor · Good solderability · Halogen-free high-temperature insulation · 300/500 V rated · 0.25–300 mm² conductor range · Flame-retardant and self-extinguishing · Non-corrosive combustion gases · Good flexibility · PFAS-free · RoHS compliant
This high-temperature single conductor cable is designed for protected internal wiring exposed to elevated ambient temperatures, particularly where dependable soldered terminations are required.
Typical applications include:
- Protected wiring zones in industrial ovens and furnaces
- Heat-treatment and thermal-processing equipment
- Industrial heaters and hot-air systems
- High-temperature control cabinets
- Electrical appliances operating near heat sources
- Generators, transformers and electrical heating equipment
- Sensors, instruments and equipment using soldered connections
- Cable harnesses installed within protected high-temperature enclosures
The silver-plated conductor supports good solderability and reliable electrical contact in high-temperature equipment. The cable is suitable for fixed installation and general flexible wiring but is not intended for continuous-flex movement unless separately qualified.

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.
