Cathodic Protection Cable
 Kynar

Where improved corrosion resistance is required as in many deep well applications, dual jacketed Kynar/HMWPE cable is recommended. Historically, anode cable is the most cause of failures is deep well anode systems. As cathodic protection anodes discharge current, high levels of chlorine gas can be generated. Chlorine gas is detrimental HMWPE insulation and the deterioration of the insulation will lead to failure of copper cable and loss of the anode in cathodic protection circuit.

With the dual insulated cable, the outer insulation jacket consists of standard HMWPE, which provides excellence physical properties such as abrasion resistance. The inner jacket consists of a homogenous wall of natural PVDF flouropolymer (Kynar), which provides excellence resistance to chlorine attack. Kynar is also resistant to many other detrimental chemicals such as hydrochloric and sulfuric acid as well as petroleum hydrocarbons.

Application

A direct earth burial, DC lead, cathodic protection cable for use in deep anode groundbed installations, designed to withstand corrosive gases.
