Puas yog nws zoo dua los xaiv cov hlau mos los yog tawv hlau?

1. Nyob rau hauv txoj kev xav, lub zog hlau yog muaj zog dua. Feem ntau, peb tuaj yeem xyuam xim rau nws. Feem ntau ntawm cov kev sib txuas uas raug hlawv hauv tsev yog tag nrho cov -core tooj liab xov hlau? Kev soj ntsuam ntawm tus kws hluav taws xob Fu: txhua tus tooj liab hlau ntawm ntau- tub ntxhais tooj liab hlau yog nyias nyias, uas yooj yim heev ua rau kev puas tsuaj thiab huab cua oxidation. Hauv kev tsim hluav taws xob hluav taws xob, raws li qhov tsis sib xws ntawm txhua qhov tooj liab, tus nqi calorific kis tsis sib xws, ua rau kev puas tsuaj ntawm qee cov xov tooj tooj liab, ua raws li kev txo qis ntawm conductivity thiab kev txhim kho ntawm cov resistors, uas ua rau muaj ntau ntawm cov khoom siv hluav taws xob. calorific nqi thiab hlawv tawm.

2. Vim hais tias tooj liab hlau yog ua los ntawm ntau-section hlau cov ntaub ntawv, nws yog ntau complex ua, tus nqi nce, thiab tus nqi tsis muaj qhov zoo tshaj plaws. Yog li ntawd, nws yog qhov zoo dua los siv cov hlau tawv. Yog li ntawd, daim ntawv thov ntawm ib tug ib tug nyuaj hlau rau cable nyob rau hauv tsev muaj ntau zoo stability thiab durability, thiab lub zog hlau yog yus muaj los ntawm yooj yim threading thiab installation, thiab tus nqi yog tus nqi ntau dua - zoo dua tooj liab hlau. Pab neeg tsim kho kuj xav hnav cov hlau nyuaj, vim tias cov hlau tawv no kuj siv tau yooj yim dua.

3. Conductivity: feem ntau, cov conductivity ntawm cov hlau tawv thiab tooj liab hlau nrog tib txoj kab uas hla yog tib yam. Txawm li cas los xij, thaum peb xaim, cov hlau tooj liab feem ntau yog yooj yim heev kom tawg ob txoj hlua tooj liab yuam kev. Txawm tias thaum qee tus pib, cov vuam lossis cov neeg siv khoom hloov lub qhov hluav taws xob, lawv feem ntau tev cov hlau ua ke nrog ib nrab ntawm cov hlau hlau. Nyob rau hauv txoj kev no, lub cable tam sim no nqa lub peev xwm ntawm lub cable yog kev puas tsuaj, thiab huab cua oxidation ntawm sab hauv tooj liab hlau yuav txuas ntxiv mus.

Nyob rau hauv sib piv, ib tug ib tug nyuaj hlau nrog ib tug thicker cable txoj kab uas hla yuav tsis muaj xws li.

4. Thaum tshem tawm thiab hloov lub cable, txawm hais tias lub zog xaim yog ua haujlwm nyuaj, nws tuaj yeem xyuas kom meej tias cov xaim xaim tuaj yeem rub tawm tau yooj yim ntawm cov xaim yeeb nkab. Thaum tsim nyog, nws tseem tuaj yeem hloov cov hlau txuas steel hlau thiab rub cov kab tshiab ua ke. Tom qab embrittlement, tooj liab hlau yog ib qho yooj yim heev rau tawg, thiab nws yog feem ntau yuav ua txhaum cov hlau tsis zoo thaum hloov cov hlau.

5. Copper wire yog multi-core wire, thiab qhov nyuaj coefficient ntawm multi strand xaim nyob rau hauv kev siv tshuab yog ntau dua li sheathed hlau, yog li tus nqi ntawm tooj liab hlau kuj siab dua cov hlau nyuaj. Thiab cov hlau tawv tawv tuaj yeem rov ua dua tom qab pov tseg, thaum cov hlau tooj liab tsis muaj qhov no. Ntxiv mus, ib qho tooj liab hlau nyob rau hauv lub tooj liab hlau yog nyias, thiab nws cov kev pab cuam lub neej yog tsis ntev tshaj li ntawm hard hlau.
