SPL™-HDP Anode

Our proprietary MATCOR flexible linear anode, factory-packaged in a semi-rigid perforated high-density polyethylene housing. This anode is primarily designed for use in concrete, beneath ASTs or in marine environments.  

Housing Specifications

  • Diameter: 1 inch (25 mm) 
  • Weight: 0.1 pound per lineal foot (0.14 kilogram/lineal meter) 
  • Flexibility:12-inch minimum bending radius without damaging the anode or kinking the plastic tube 
  • Jacket: Continuous, permeable, heavy duty, suitable for field handling and for direct burial, made of semi-rigid, perforated high-density polyethylene 
  • The perforation will be sized so as to permit the passage of sand and to allow contact between the sand and the primary anode 
  • The perforation size shall be such that there is no electrical short between the primary anode and cathode 

Primary Anode Properties

  • Composition: Mixed metal oxide or platinum/niobium/copper core 
  • Inert in the presence of chlorine 
  • Life: Dependent upon the primary anode, not backfill 
  • Configuration: Segmented anodes are not accepted—the primary anode will run continuously within the polyethylene tube 

Internal Header Cable Properties

  • Composition: 7-strand copper cable 
  • Insulation: Standard: HMWPE 
  • Chemically abusive soils: PVDF/PE or ECTFE/HMWPE 
  • Connections: Primary Anode to Internal Header Cable: 10-foot intervals minimum 
  • Multi-step and waterproof 


  • None Required
