Cathodic Protection Cable is a single conductor cable that is intended to carry a DC current to anodes and cathodes in a cathodic protection system. This specification describes a stranded copper conductor with dual insulation.
The primary layer of insulation is composed of KYNAR (also known as PVDF, Polyvinylidene fluoride), a fluoropolymer material that has exceptional chemical resistance in the presence of chlorine, sulfuric acid, and hydrochloric acid.
The outer insulation layer is a low-density, high molecular-weight polyethylene (HMWPE), which exhibits superior dielectric and tensile strength, provides mechanical protection to the primary layer, and withstands considerable abuse during installation.
KYNAR is also inherently flame resistant, making KYNAR cables suitable for applications where fire safety is a concern. In addition, KYNAR has good electrical insulation properties, making KYNAR wires suitable for electrical and electronic applications that require stable and reliable signal transmission.
Construction
Conductor: Stranded Bare or Tinned Copper, conforms to ASTM B-3 & B-8

KYNAR Cathodic Protection Cable by Performance Wire & Cable is made with fluoropolymer insulation with exceptional chemical resistance. KYNAR cable consists of a layer of insulation on the conductor, followed by a layer of HMWPE (high molecular weight polyethylene) insulation.
KYNAR insulation is extremely resistant to chlorine, sulfuric acid, and hydrochloric acid, which the HMWPE alone cannot withstand. HMWPE outer jacketing can provide flexible strength and can withstand much abuse during installation without damaging the conductor. KYNAR wire is available in 8 AWG through 1/0 AWG sizes.
Additional KYNAR Applications and Specifications:
- KYNAR/HMWPE cables are used as deep anode lead wires where chlorine and hydrogen gases are generated.
- The KYNAR cable can be directly installed in fresh, brackish, or salt waters.
- The primary insulation is a homogeneous 20 mil wall of natural PVDF fluoropolymer (Kynar) that shall be extruded around the conductor.
- The jacket is a 65 mil wall of high molecular weight polyethylene (HMWPE) that shall be extruded around the primary insulation, and the jacket conforms to ASTM Spec D 1248.
- For identification purposes, the cable shall be surface printed with “Manufacturer name Conductor size AWG, KYNAR / HMWPE CATHODIC PROTECTION CABLE.”
