Cov ntaub ntawv dav dav
Nqe lus piav qhia:
Nws yog tsim los ntawm kev sib xyaw, plasticization thiab granulation nrog cov polyethylene tsawg-density raws li cov cob qhia yooj yim sib xyaw nrog tus neeg sawv cev sib txuas thiab lwm yam khoom ntxiv. Nws tsis muaj cov khoom tsim kev puas tsuaj xws li cov hlau hnyav thiab muaj cov khoom siv zoo heev, hluav taws xob thiab hluav taws xob thaum tshav kub kub nrog cov txheej txheem ruaj khov nrog rau qhov chaw du. Nws yog siv los ua rwb thaiv tsev rau MV Fais Fab Cable.
Specifications:
XLPE Compound rwb thaiv tsev rau MV cable txog 35kV.
