Xlpe Cable Manufacturing Process

Cable manufacturing process in demirer kablo includes wire drawing stranding insulating outer sheating is the last stage of cable manufacturing process.

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. 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. Ccv and vcv in the dry state dry curing dry cooling can produce medium and high voltage cable. Electrical cable is by drawing stranding covered of three kinds of process to complete specifications are more complex higher repeatability.

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. In this post we re going to talk about the common and crucial steps of cable manufacturing. 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. Polyethylene has been and still is used as a cable insulant but as a thermoplastic material its applications are limited by thermal constraints.

First of all let s clarify two nouns. 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. 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. Xlpe insulation can be modified to limit the amount of by product gases generated during the cross linking process.

Cross linked polyethylene is produced from polyethylene under high pressure with organic peroxides as additives. Especially there are always multiple conductors stranded together we ll explain why in the following content within a single. 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. Under heat and pressure the cross linking takes place.

Generally we call a single conductor a wire while a cable is two or more insulated wires wrapped in one jacket. Jul 01 2012 alvern cables manufacturing process relicab cable manufacturing private limited wire cable making process factory manufacturing process demirer kablo.
