DETERIORATION OF 600-VOLT CABLE SHEATHS BY FLOTATION-TYPE CORROSION INHIBITORS

Abstract

Failure of cathodic protection systems has been attributed to the deterioration of sheathing of electrical conductor cables immersed in flotation- type corrosion inhibitors. Cable manufacturers and distributors were asked to recommend a sheath material for cathodic protection cables in floating dry-dock ballast tanks. Materials suggested were polyethylene, polyvinyl chloride, neoprene, and a butadiene-acrylonitrile copolymer. Quantities of cables sheathed with these materials were ordered and tested with stock cables obtained from Naval supply sources. A butadiene-acrylonitrile copolymer was found to be superior to all others after 300 hr of immersion in typical flotation-type corrosion inhibitors. The next most resistant was the polyvinylchloride sheath, followed closely by a Navy stock neoprene and a homogeneous polyethylene serving as both jacket and insulation.
