Cathodic Protection Cable (CPC) is used in Cathodic protection systems designed to protect steel, water or fuel pipelines and storage tanks, steel pier piles, ships, offshore platforms and onshore well casings from corrosion. CPC helps make sure your metal lasts as long as possible when exposed to the earth’s electrical charge.

CPC typically consists of a stranded copper conductor insulated from the surrounding soil by one of the following:

  • A single layer of High Molecular Weight Polyethylene (HMWPE) insulation which in most applications is 0.110″ thick (110 mils).
  • A fluoropolymer insulation, usually 0.020″ (20 mils) of Halar (ECTFE) protected by a 0.065″ (65 mils) Polyethylene (HMWPE) jacket is typically used where halogen gases such as fluorine, chlorine, bromine etc. are present and concentrated around the anode and the cable. These types of cables are commonly called “Halar” or “Kynar” Cathodic Protection Cables.

The OVERPIPE® protection plates are made of injected HDPE. They have dedicated features such as:

•  Holes all over the surface (but less than 1% of the total surface) to allow the flow of water to go through and not disrupt the measurement of the cathodic protection. The holes come from molding and not by later drilling which would weaken the plate.
•  Beveled edges and non-slip pins on both sides to facilitate handling and avoid slip and fall accidents.
•  Full body yellow color (UV resistant) as an effective warning signal (different colors possible depending on the nature of the networks).
•  Fully customizable embossed warning message.

The OVERPIPE® protection plates come in various dimensions to fit with the pipe diameter and to grant an extra width on the sides. The plates are assembled by superposition (10 cm / 4 inch overlap) or by juxtaposition and are linked by HDPE clips and caps.
