SPL™-GFC Anode

Our proprietary MATCOR flexible linear anode, factory-packaged with coke backfill in a flexible galvanized steel housing. This anode is primarily designed for use in rocky or high soil resistance environments, or in congested areas where interference may be a concern.  

Housing Specifications 

  • Diameter: 1.50 inches (38 millimeters) 
  • Weight: 2 pounds per lineal foot (2.8 kilograms/lineal meter) 
  • Flexibility: 12-inch minimum bending radius without damaging the anode or steel tube 
  • Jacket: Continuous, non-permeable, heavy duty, suitable for field handling and for direct burial, made of galvanized steel material 

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 steel 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 


The steel tube will be tightly filled with coke backfill having the following properties: 

  • Type: Calcined petroleum coke 
  • Fixed Carbon: 99.8% 
  • Moisture: 0.07% 
  • Volatile: 0.02% 
  • Ash: 0.1% 
  • Particle Size: 1.0 millimeter (max.)
