THW waya chinhu chinogoneka chemagetsi waya zvinhu zvine zvakanakira zvekupisa tembiricha kuramba, kupfeka kuramba, yakakwirira voltage simba, uye nyore kuisa.THW waya inoshandiswa zvakanyanya mukugara, kutengeserana, pamusoro, uye pasi pevhu tambo tambo, uye kuvimbika kwayo uye hupfumi hwave humwe hwezvinhu zvinofarirwa waya mumaindasitiri ekuvaka nemagetsi.
Chii chinonzi THW waya
THW waya imhando ye-general-chinangwa tambo yemagetsi iyo inonyanya kuumbwa neconductor yakagadzirwa nemhangura kana aruminiyamu uye chinhu chekudzivirira chakagadzirwa ne polyvinyl chloride (PVC).THW inomirira Plastics High-temperature-resistant Aerial Cable.Iyi waya inogona kushandiswa kwete chete kune indoor kugovera masisitimu asiwo kune pamusoro uye pasi pevhu tambo tambo, ine huwandu hwakawanda hwekushandisa.THW waya inoshandiswa zvakanyanya muNorth America nedzimwe nzvimbo uye inozivikanwa zvikuru.
Zvimiro zveTHW waya
1.Kupisa kwekushisa kwepamusoro, THW wire inoshandisa PVC zvinhu sevhavha yekudzivirira, iyo inoita kuti waya ive nepamusoro-soro yekudzivirira uye inogona kumira kupisa kwekushanda kwepamusoro uye mutoro wezvino.Naizvozvo, waya yeTHW yakanyatsokodzera kushandiswa munzvimbo dzepamusoro-tembiricha.
2.Kupfeka kupikisa, sheath yekunze yeTHW wire yakagadzirwa nePVC zvinhu, izvo zvinogona kunyatsodzivirira waya kubva pakupfeka uye kukanganisa.Iyi waya haina kukanganiswa nekunze kwemuviri kana kemikari zvinhu uye inogona kuchengetedza kuita kwayo kwakanaka kwenguva yakareba.
3.High voltage capacity, THW wire ine high voltage-bearing capacity uye inogona kushanda zvakachengeteka pasi pemamiriro epamusoro.Waya iyi inokwanisa kumira nevoltage yakawanda ye600V, iyo inokwanisa kusangana nezvinodiwa zvevakawanda zvekugara uye zvekutengesa zvikumbiro.
4.Easy kuisa, THW wire inenge yakasununguka, zvichiita kuti zvive nyore kwazvo kuisa uye waya.Nekuda kwekusagadzikana kwayo uye kuchinjika, waya yeTHW inogona kukotama uye kumonyoroka zviri nyore, zvichiita kuti kuisirwa kuve nyore.
Kushandiswa kweTHW waya
1.Residential uye kushandiswa kwekutengeserana, THW wire ndiyo chikamu chikuru chematunhu emukati uye kugovera zvirongwa zvezvivako, zvinowanzoshandiswa pakupa magetsi emidziyo yakasiyana-siyana yemumba yakadai semarambi, zvigadziko, terevhizheni, uye air conditioners.
2.Overhead cable mitsara, nekuda kweTHW wire ye-high-temperature resistance uye kupfeka kusagadzikana, inogona kumira zvakanyanya mamiriro ekunze uye kunze kwekunze kwezvakatipoteredza, saka inoshandiswa zvakanyanya mumitsetse yetambo yepamusoro.
3.Underground cable lines, iyo insulation layer yeTHW wire inogona kudzivirira tambo kuti isasangana nemvura kana mamwe mamiriro ekunze, saka inowanzoshandiswa mumitsara yetambo yepasi.Waya iyi inogona kuramba hunyoro uye nharaunda dzakanyorova uye zvakare inogona kudzivirira waya kubva mukuora uye kupera.
THW waya VS.THWN waya
THW waya, THHN waya uye THWN waya zvese zvakakosha single core waya zvigadzirwa.THW waya uye THWN waya dzakanyanya kufanana pakutaridzika uye zvinhu, asi mumwe musiyano wakakosha pakati pawo mutsauko wekudzivirira uye jekete zvinhu.Waya dzeTHW dzinoshandisa polyvinyl chloride (PVC) insulation, nepo THWN waya dzinoshandisa giredhi repamusoro rethermoplastic polyethylene (XLPE) insulation.Kana ichienzaniswa nePVC, XLPE iri pamusoro mukuita, ine mvura iri nani kuramba uye tembiricha kuramba.Kazhinji, tembiricha yekushanda yeTHWN waya inogona kusvika 90 ° C, nepo iyo yeTHW waya ingori 75 ° C, kureva kuti, THWN waya ine yakasimba kupisa kupisa.
THW waya VS.THHN waya
Kunyangwe ese mawaya eTHW neTHHN akaumbwa newaya uye matanda ekuvharisa, mutsauko wezvinhu zvekudzivirira unotungamira kukuita kwavo kwakasiyana mune zvimwe zvinhu.Waya dzeTHW dzinoshandisa polyvinyl chloride (PVC) zvinhu, nepo THHN waya dzinoshandisa yakakwirira-tembiricha epoxy acrylic resin (THERMOPLASTIC HIGH HEAT RESISTANT NYLON), iyo inoramba yakagadzikana pakupisa kwakanyanya.Pamusoro pezvo, waya dzeTHW dzinowanzo kupfava kupfuura waya dzeTHHN kuti dzienderane nezvakawanda zvekushandisa.
THW waya uye THHN waya dzinosiyanawo mukupihwa zvitupa.Ose ari maviri UL neCSA, iwo maviri makuru ekumisikidza zvitupa masangano muUnited States neCanada, anopa chitupa cheTHW uye THHN waya.Nekudaro, iyo certification maitiro evaviri akasiyana zvishoma.THW waya inoda kupihwa UL Certified, nepo THHN waya ichida kuzadzisa zvinodiwa neUL neCSA certification agency.
Kupfupisa, THW waya chinhu chinoshandiswa zvakanyanya waya, uye kuvimbika kwayo uye hupfumi hwave humwe hwezvinhu zvinofarirwa waya zveindasitiri yekuvaka uye indasitiri yemagetsi.THW waya ine mashandiro akanaka uye inogona kusangana nezvinodiwa zvezviitiko zvakasiyana, zvichiunza nyore uye kuchengetedzeka kuhupenyu hwedu neindasitiri.
