Cable, Halar/HMWPE Insulation for Cathodic Protection by Farwest Corrosion
Primary Halar Insulation, Secondary HMWPE Insulation for Cathodic Protection Systems
Application
A direct burial cable for use in cathodic protection deep well installations or other situations where resistance to chlorine gas is required.
The primary ECTFE (Halar) insulation provides chemical resistance properties. The secondary or outter jacket of high molecular weight polyethylene (HMWPE) provides abrasion resistance.
Standards
- Conductor
Stranded bare copper conductor conforms to ASTM Specification B-8. - Insulation
A homogeneous wall of natural ECTFE fluoropolymer (Halar) shall be extruded over the conductor. - Jacket
Insulation is high molecular weight polyethylene conforming to ASTM-D-1248, Type 1, Class A, Category 5, Grades E4 and E5. Tensile Strengths Jl, J3. Available with high density polyethylene (Types II, III, IV) Class B and C (all colors). Surface printed. Custom printing available.
