Product Detail
Cable HALAR/HMWPE for cathodic protection
Brief Introduction
HALAR/HMWPE cable is designed for anode lead wires in a wide
range of environments. One of the major
causes of deep anode failures is the failure of cable insulation. This is
especially evident in areas where brackish water is present in the ground. In
this environment, anodes generate reactive gases such as chlorine and na-cent
oxygen. These gases cause rapid deterioration of conventional HMWPE insulation.
Cathodic protection cable insulated
with HALAR fluoropolymer, is especially suited for deep anode lead wires. HALAR
fluoropolymer is inert to reactive compounds and has an outstanding ability to
prevent the passage of gases. Laboratory and field evaluations indicate that
HALAR fluoropolymer insulated lead wire can extend the life of deep anode
installations.
The cable is
composed of stranded copper wire covered by two layers of insulation. The outer
insulation layer is made from high molecular weight polyethylene (HMWPE). It
exhibits superior dielectric and tensile strength, and provides mechanical
protection to the cable.
The material is also resistant to water
intrusion and is not affected by most organic or inorganic substances. The
inner or primary insulation is composed of HALAR, a fluoropolymer. This
insulating material demonstrates exceptional chemical resistance. In the
presence of chlorine, hydrochloric acid, sulfuric acid, or other strong
oxidizing agents the material remains stable. Further, it will not deteriorate
when exposed to petroleum hydrocarbons which are encountered in numerous
cathodic protection applications.
