THHN, THWN uye THW ese marudzi emumwechete conductor waya yemagetsi inoshandiswa mudzimba uye zvivakwa kuendesa simba. Kare, THW THHN THWN yaive waya dzakasiyana dzine mvumo dzakasiyana uye maapplication. Asi Ikozvino, heino generic THHN-2 waya inovhara zvese zvinotenderwa kune ese akasiyana eTHHN, THWN uye THW.
1. Chii chinonzi THW Wire?
Thw wire inomirira thermoplastic, waya inodzivirira kupisa uye inodzivirira mvura. Yakagadzirwa nemhangura conductor uye PVC insulation. Inoshandiswa kune magetsi uye magetsi emagetsi mumaindasitiri, mabhizimisi uye nzvimbo dzekugara. Rudzi urwu rwewaya runogona kushandiswa munzvimbo dzakaoma uye dzakanyorova, tembiricha yaro yekushanda i75 ºC uye voltage yayo yebasa kune ese maapplication i600 V.
Zvakare, iyo acronym THW inoshaya iyo "N" yenaironi-yakashongedzwa. Iyo nylon yekupfekedza inoita senge chidimbu chepurasitiki uye inodzivirira waya nenzira dzakafanana. Pasina iyo naironi yekuputira, THW waya mutengo wakachipa asi inopa dziviriro shoma kubva kune akasiyana siyana nharaunda.

2. Chii chinonzi THWN THHN Wire?
THWN neTHHN vese vachiwedzera iyo "N" muchidimbu, zvinoreva kuti ese iwaya yakavharwa naironi. THWN waya yakafanana neTHHN. THWN waya haipindi mvura, ichiwedzera “W” muchidimbu. THWN iri nani pane THHN mukuita isingadzivirirwe nemvura. THHN kana THWN ese anogona kushandiswa semagetsi uye mwenje maseketi mumaindasitiri, ekutengesa uye ekugara zvivakwa, iwo akanyatso kukodzera kuiswa kwakakosha kuburikidza nemadhakisi akaoma uye kushandiswa munzvimbo dzinoputika kana kusvibiswa nemafuta, girisi, peturu, nezvimwewo uye zvimwe zvinoparadza makemikari zvinhu sependi, zvinonyungudutsa, nezvimwe.
