Monday, 14 May 2018 00:00


    • Description & Features

    BORNA Godaz company has proceeded for supplying kynar (HMWPE/PVDF) cable with high quality and reasonable cost as the largest manufacturer of cathodic protection anodes in different shapes and accessories in Iran. This activity has begun in our company in order to complete cathodic protection products and solving of corrosion protection industry problems in the country, due to the lack of reliable HMWPE / PVDF cable in Iran. The inner layer or the primary insulation is composed of KYNAR, a flouropolymer material that has exceptional chemical resistance in the present of chlorine, sulfuric acid and hydrochloric acid. Also, the outer insulating layer is high molecular weight polyethylene (HMWPE). This material as a single conductor cathodic protection cable exhibits superior dielectric and tensile strength and provides mechanical protection and can withstand corrosive gases and brackish water conditions during installation and performance. It should be noted that these cables have excellent resistance to environments containing of chloride ions , H2S gas as sour gas, oxygen and chlorine gases.

    • Application:

    KYNAR/HMWPE cables are used as deep anode lead wires where chlorine and hydrogen gases are generated. The cable can be directly installed in fresh, brackish, or salt waters. Also, it is used for direct earth burial DC feeder cable for cathodic protection systems, tanks, pipelines, wells, ocean vessels, and metal structures buried or water submerged.

    • Standards:

    Construction of this cable must be conformed to ASTM Spec B-3 , B-8 and ASTM Spec D1248.
