RG 179 Type 75 Ohm High-Temperature FEP Coaxial Cable

This RG 179 type coaxial cable combines a 75 Ω impedance with FEP insulation, an FEP outer sheath and silver-plated shielding for reliable high-frequency signal transmission. It provides excellent electrical insulation, chemical resistance and flexibility across an extended temperature range from -90°C to +180°C.

Key Highlights

RG 179 reference construction · 75 Ω characteristic impedance · Frequency range up to 1 GHz · Silver-plated conductor and braid · FEP insulation and outer sheath · Temperature resistance up to +180°C · Fixed installation down to -90°C · Low and stable dielectric characteristics · Excellent chemical and solvent resistance · Compact 2.54 mm diameter · RoHS compliant

About Hulk Electric

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.

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.
