Tumizani ImeloZingwe za LSZH MV zimaphatikizansopo zingwe za PVC single-core AWA ndi zingwe za XLPE zamitundu yambiri za SWA.
Kapangidwe kameneka kamakonda kugwiritsidwa ntchito pazingwe zamagetsi zothandizira pamagulu amagetsi ndi malo osiyanasiyana.Zida zomwe zikuphatikizidwazo zikutanthauza kuti chingwecho chikhoza kukwiriridwa pansi kuti chiteteze kugwedezeka mwangozi ndi kuwonongeka.
Zingwe za LSZH ndizosiyana ndi zingwe za PVC ndi zingwe zopangidwa ndi zinthu zina.
Chingwe chikagwira moto, chimatha kutulutsa utsi wambiri wakuda ndi mpweya wapoizoni.Komabe, chifukwa chingwe cha LSZH chimapangidwa ndi zinthu za thermoplastic, chimatulutsa utsi wochepa komanso mpweya wapoizoni, ndipo chilibe mpweya wa acidic.
Zimapangitsa kuti anthu azitha kuthawa moto kapena malo oopsa.Choncho, nthawi zambiri amawaika m’nyumba, monga m’malo opezeka anthu ambiri, malo ena oopsa, kapena m’malo opanda mpweya wabwino.

Kuti zitheke komanso kukhala ndi moyo wautali, chingwe chilichonse cha MV chiyenera kupangidwa kuti chigwirizane ndi kuyikapo koma pali nthawi zina pomwe chingwe cha bespoke chimafunika.Akatswiri athu a chingwe cha MV amatha kugwira ntchito nanu kupanga yankho lomwe likugwirizana ndi zomwe mukufuna.Nthawi zambiri, makonda amakhudza kukula kwa chigawo chachitsulo chachitsulo, chomwe chingasinthidwe kuti chisinthe mphamvu yafupikitsa yozungulira ndi makonzedwe a nthaka.
Munthawi zonse, chidziwitso chaukadaulo chimaperekedwa kuti chiwonetse kukwanira komanso kutsimikizika komwe kumapangidwa.Mayankho onse osinthidwa makonda amayenera kuyesedwa kopitilira muyeso mu MV Cable Testing Facility yathu.
