HMWPE Cable
HMWPE Direct Burial Cable
The cable utilized in a cathodic protection system is a critical component of any cathodic protection system. MESA provides cable manufactured specifically for cathodic protection applications from a variety of cable manufacturers. The industry standard cable for direct burial is a stranded copper conductor covered with an insulation of high molecular weight polyethylene (HMWPE). The thick insulation provides both electric isolation and mechanical protection. During installation, this cable can withstand considerable mechanical abuse without compromising the conductor. The HMWPE insulation is chemically resistant and protects against most organic and inorganic substances.
Application:
A direct earth burial DC feeder cable for use in cathodic protection systems, for storage tanks, pipelines, wells, vessels and metallic structures either buried or water submerged.
Standards:
· Conductor
o Stranded copper conductor conforms to ASTM Specification B-8
· Insulation
o Insulation is high molecular weight polyethylene conforming to ASTM D-1248, Type I, Class A, Category 5, Grades E-4 & E-5. Tensile Strengths J1, J3. Available with high density polyethylene (Type II, III, IV) Class B & C (all colors).
Construction:
· Annealed, uncoated, stranded copper conductor, HMW polyethylene black insulation. Surface or indent printed. Custom printing available.
