Xlpe cable manufacturing process. This paper aims to analyze the quality of insulation in high voltage underground cables xlpe using a prototype which classifies the following usual types of patterns of partial discharge pd. Citation needed this is particularly useful for high voltage cable and extra high voltage cable applications where degassing requirements can significantly lengthen cable manufacturing time. Electrical cable manufacturing process xlpe cable armoured cable power cable urd cable. Xlpe cablesadopt two semiconductor shielding and insulating three layer coextrusion and three layer co extrusion in the production process can ensure product surface highly smooth avoid air gap and impurities to enter.

Generally we call a single conductor a wire while a cable is two or more insulated wires wrapped in one jacket. 1 internal pd 2 superficial pd 3 corona discharge in air and 4 corona discharge in oil in addition to considering two new pd patterns. Under heat and pressure the cross linking takes place. Manufacturing process of xlpe cable in the manufacture of medium and high voltage xlpe cable our plant uses the latest technology available in the fieldby using an integrated high performance extrusion line which consists of a triple layer crosshead and a water free completely dry curing and cooling cdcc gas vulcanizing process.

Cable manufacturing process in demirer kablo includes wire drawing stranding insulating outer sheating is the last stage of cable manufacturing process. 6 35 11kv xlpe cable is used indoor or outdoor in tunnel cable furrow or pipe to be laid underground be applicable to the well water inside and fall in the bad soil. Xlpe insulation can be modified to limit the amount of by product gases generated during the cross linking process. Xlpe and hpte insulated medium and high voltage cable today insulation material that is mainly in use for mv and hv cables is cross linked polyethylene xlpe.

Ccv and vcv in the dry state dry curing dry cooling can produce medium and high voltage cable. 1 false contact and 2 floating ground. Cross linking is the effect produced in the vulcanization of rubber and for materials like xlpe the cross linking process is often described as vulcan ization or curing. Especially there are always multiple conductors stranded together we ll explain why in the following content within a single.

Electrical cable is by drawing stranding covered of three kinds of process to complete specifications are more complex higher repeatability. Polyethylene has been and still is used as a cable insulant but as a thermoplastic material its applications are limited by thermal constraints.
