KYNAR/HMWPE cathodic protection cable is made with a fluoropolymer insulation that has exceptional resistance to chemicals. KYNAR cable consists of a layer of insulation on the conductor, followed by a layer of HMWPE (high molecular weight polyethylene) insulation.
The KYNAR insulation is extremely resistant to chlorine, sulfuric acid and hydrochloric acid, which the HMWPE alone cannot withstand.
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
Conductors are stranded bare or tinned copper conductor conforms to ASTm spec B-3 and B-8
The primary insulation is a homogeneous 20 mil wall of natural PVDF fluoropolymer (KYNAR) shall be extruded around the conductor
The jacket is a 65 mil wall of high molecular weight polyethylene (HMWPE) shall be extruded around the primary insulation, and the jacket conforms to ASTm spec D 1248
