Waya wa THW ndi waya wamagetsi wosunthika womwe uli ndi zabwino zokana kutentha kwambiri, kukana kuvala, mphamvu yamagetsi apamwamba, komanso kukhazikitsa kosavuta.Waya wa THW amagwiritsidwa ntchito kwambiri pazingwe zogona, zamalonda, zapamwamba, komanso zapansi panthaka, ndipo kudalirika kwake komanso chuma chake chakhala chimodzi mwazinthu zomwe amazikonda kwambiri pamafakitale omanga ndi magetsi.
Kodi THW waya ndi chiyani
Waya wa THW ndi mtundu wa chingwe chamagetsi chomwe chimagwiritsidwa ntchito nthawi zonse chomwe chimapangidwa makamaka ndi kondakitala wopangidwa ndi mkuwa kapena aluminiyamu komanso zinthu zotsekereza zopangidwa ndi polyvinyl chloride (PVC).THW imayimira Plastics High-temperature-resistant Aerial Cable.Waya uwu ukhoza kugwiritsidwa ntchito osati kokha pamakina ogawa m'nyumba komanso mizere yam'mwamba ndi pansi, yokhala ndi ntchito zambiri.Waya wa THW amagwiritsidwa ntchito kwambiri ku North America ndi madera ena ndipo ndi otchuka kwambiri.
Zithunzi za THW waya
1.Kutentha kwakukulu kwa kutentha, THW waya imagwiritsa ntchito PVC zinthu monga zosanjikiza zotsekemera, zomwe zimapangitsa kuti waya akhale ndi kutentha kwapamwamba kwambiri ndipo amatha kupirira kutentha kwakukulu kwa ntchito ndi katundu wamakono.Chifukwa chake, waya wa THW ndi woyenera kwambiri kugwiritsidwa ntchito m'malo otentha kwambiri.
2.Kuvala kukana, chophimba chakunja cha waya wa THW chimapangidwa ndi zinthu za PVC, zomwe zingathe kuteteza bwino waya kuti asawonongeke ndi kuwonongeka.Waya uyu samakhudzidwa ndi zinthu zakunja zakuthupi kapena zamankhwala ndipo amatha kukhalabe ndikuchita bwino kwa nthawi yayitali.
3.Kuchuluka kwamagetsi, waya wa THW ali ndi mphamvu yothamanga kwambiri ndipo amatha kugwira ntchito motetezeka pansi pazigawo zamphamvu kwambiri.Waya uwu ukhoza kupirira mphamvu yamagetsi ya 600V, yomwe ingakwaniritse zosowa za nyumba zambiri ndi malonda.
4.Easy kukhazikitsa, waya wa THW ndi wosavuta kusintha, zomwe zimapangitsa kuti zikhale zosavuta kukhazikitsa ndi waya.Chifukwa cha kusinthasintha kwake komanso kusinthasintha, waya wa THW amatha kupindika komanso kupindika mosavuta, ndikupangitsa kuti kuyikako kukhale kosavuta.
Kugwiritsa ntchito waya wa THW
1.Kugwiritsidwa ntchito kwanyumba ndi malonda, waya wa THW ndilo gawo lalikulu la maulendo amkati ndi machitidwe ogawa nyumba, omwe amagwiritsidwa ntchito popangira magetsi a zipangizo zosiyanasiyana zapakhomo monga nyali, zitsulo, ma TV, ndi ma air conditioners.
Mizere ya 2.Overhead chingwe, chifukwa cha kutentha kwa THW kwa waya ndi kukana kuvala, imatha kupirira nyengo yovuta komanso zotsatira za kunja kwa chilengedwe, choncho imagwiritsidwa ntchito kwambiri pamizere ya chingwe chapamwamba.
3.Underground chingwe mizere, kusungunula wosanjikiza wa THW waya angalepheretse waya kukumana ndi madzi kapena malo ena kunja, choncho nthawi zambiri ntchito mizere pansi pansi chingwe.Wayawu umatha kukana chinyezi komanso malo onyowa komanso umatha kuteteza waya kuti usachite dzimbiri ndi kutha.
THW waya VS.Mtengo wa THWN
Waya wa THW, waya wa THHN ndi waya wa THWN zonse ndizinthu zoyambira pawaya imodzi.Mawaya a THW ndi mawaya a THWN ndi ofanana kwambiri m'mawonekedwe ndi zida, koma kusiyana kumodzi kwakukulu pakati pawo ndikusiyana kwa zotchingira ndi jekete.Mawaya a THW amagwiritsa ntchito insulation ya polyvinyl chloride (PVC), pomwe mawaya a THWN amagwiritsa ntchito insulation ya thermoplastic polyethylene (XLPE) yapamwamba kwambiri.Poyerekeza ndi PVC, XLPE ndiyopambana pakuchita, yokhala ndi kukana kwamadzi bwino komanso kukana kutentha.Kawirikawiri, kutentha kwa ntchito kwa waya wa THWN kumatha kufika 90 ° C, pamene waya wa THW ndi 75 ° C okha, ndiko kuti, waya wa THWN ali ndi mphamvu yotsutsa kutentha.
THW waya VS.Mtengo wa THHN
Ngakhale mawaya onse a THW ndi mawaya a THHN amapangidwa ndi mawaya ndi zigawo zotchingira, kusiyana kwa zida zotsekera kumabweretsa magwiridwe antchito osiyanasiyana pazinthu zina.Mawaya a THW amagwiritsa ntchito zinthu za polyvinyl chloride (PVC), pomwe mawaya a THHN amagwiritsa ntchito kutentha kwambiri kwa epoxy acrylic resin (THERMOPLASTIC HIGH HEAT RESISTANT NYLON), yomwe imakhala yokhazikika pakutentha kwambiri.Kuphatikiza apo, mawaya a THW nthawi zambiri amakhala ofewa kuposa mawaya a THHN kuti agwirizane ndi zochitika zingapo.
Mawaya a THW ndi mawaya a THHN amasiyananso paziphaso.UL ndi CSA, mabungwe awiri akuluakulu ovomerezeka ku United States ndi Canada, amapereka chiphaso cha mawaya a THW ndi THHN.Komabe, zovomerezeka za awiriwa ndizosiyana pang'ono.Waya wa THW uyenera kukhala ndi satifiketi ya UL, pomwe waya wa THHN uyenera kukwaniritsa zofunikira zamabungwe otsimikizira za UL ndi CSA.
Mwachidule, waya wa THW ndi waya wogwiritsidwa ntchito kwambiri, ndipo kudalirika kwake komanso chuma chake chakhala chimodzi mwazinthu zomwe amazikonda kwambiri pamakampani omanga ndi mafakitale amagetsi.Waya wa THW umagwira ntchito bwino kwambiri ndipo umatha kukwaniritsa zosowa zanthawi zosiyanasiyana, kubweretsa kumasuka komanso chitetezo m'moyo wathu ndi mafakitale.
