Application fit

Is HMWPE Cathodic Protection Cable right for your machine?

The industry-standard direct-burial DC power cable for pipeline cathodic protection rectifier positive headers, negative structure return drains, shallow horizontal groundbeds, storage tank bottom grids and sacrificial magnesium/zinc anode leads.

TBM gantry & advancing tunnel reel

Suitable

Heavy 2.79–3.18 mm (110–125 mil) HMWPE wall resists rock impingement, backfill settlement and trench plowing without conduit.

Immersion & wet locations

Suitable

Ultra-low water permeability (< 0.01 % absorption) prevents soil moisture from reaching the positive DC copper conductor.

Fixed installation

Suitable

Terminated directly in transformer-rectifier cabinets, anode junction boxes and exothermic (Cadweld) pipe bonds.

Furnace, kiln & high-temp zone

Not suitable

For deep-well boreholes saturated with concentrated nascent chlorine (Cl₂) gas, specify dual-layer ECTFE/HMWPE or PVDF/HMWPE.

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why does cathodic protection cable use a 110 mil (2.79 mm) HMWPE wall instead of standard building wire (THWN / RHW-2)?
In an Impressed Current Cathodic Protection (ICCP) positive header cable buried in moist soil, the copper conductor is held at a positive DC potential relative to the earth. Any microscopic pinhole, nick or moisture permeation in ordinary PVC/nylon wire will cause anodic electrolysis that dissolves the copper conductor in weeks. A single-extruded 110 mil High-Molecular-Weight Polyethylene (HMWPE) wall has near-zero water permeability and extreme abrasion resistance.
What does 'ASTM D1248 Type I, Class C, Category 5, Grade E5' mean?
Type I specifies low-density branched polyethylene (0.910–0.925 g/cm³) for low stiffness; Class C specifies ≥ 2 % weather-resistant carbon black; Category 5 specifies the lowest Melt Flow Index (≤ 0.4 g/10 min), which corresponds to the highest molecular weight and highest environmental stress-crack resistance (ESCR); and Grade E5 specifies electrical dielectric purity.
When should I upgrade from single-layer HMWPE to dual-layer ECTFE/HMWPE or PVDF/HMWPE?
Use single-layer HMWPE for surface header trenches, negative pipeline return leads and shallow groundbeds. Upgrade to dual-layer ECTFE/HMWPE or PVDF/HMWPE for individual anode tail leads lowered into deep-well boreholes or saline groundbeds where trapped nascent chlorine gas (Cl₂) attacks polyethylene.
What factory routine tests and certificates are supplied with HMWPE Cathodic Protection Cable?
Every production drum of HMWPE Cathodic Protection Cable undergoes 100 % conductor DC resistance measurement at 20 °C, high-voltage AC/DC dielectric withstand testing, and dimensional verification per NACE SP0169 / ASTM D1248 Type I Class C Cat 5 / ICEA S-95-658, supplied with an EN 10204 3.1 inspection certificate.
