RG 179 Type FEP Coaxial Cable 75 Ω

This 75 Ω coaxial cable features a seven-strand silver-plated conductor, FEP insulation, silver-plated copper braid and a black FEP outer sheath. It provides stable high-frequency transmission, excellent chemical resistance and reliable performance across an extended temperature range.

Key Highlights

75 Ω characteristic impedance · Silver-plated conductor · Silver-plated braid · FEP insulation and sheath · Up to +180°C · Excellent chemical resistance · Low-temperature flexibility · Compact 2.54 mm diameter · Stable dielectric performance · RoHS compliant

Application
Construction
Technical Data
Dimensions
Packaging

Designed for broadband and high-frequency signal transmission in equipment requiring compact dimensions, stable electrical characteristics and resistance to elevated temperatures or aggressive chemicals.

Typical applications include:

Broadband transmission equipment
RF signal and communication systems
Industrial measurement instruments
Electronic testing equipment
High-temperature communication devices
Chemical processing and laboratory equipment
Compact internal coaxial connections

The FEP insulation and sheath make the cable particularly suitable for applications exposed to acids, solvents, chemicals and extreme operating temperatures.

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.
