Muaj ntau txoj hauv kev kom paub qhov txawv ntawm cov tub ntxhais hlau yog tooj liab lossis txhuas core:
First of all, from the model of the wire, the meanings of the letters in the model are as follows: B—fixed laying; X—rubber insulation; L—aluminum core (copper core without letters); W—neoprene sheath; Y—polyethylene sheath set. Such as: BXW - copper core rubber insulated neoprene sheathed wire; BLXW - aluminum core rubber insulated neoprene sheathed wire.
Secondly, nws yog intuitive kom paub qhov txawv ntawm cov hlau core khoom. Cov tub ntxhais hlau ntawm cov tub ntxhais tooj liab hlau yog ua los ntawm tooj liab, thiab cov hlau tseem ceeb ntawm cov tub ntxhais hlau yog ua los ntawm txhuas. Txij li thaum tooj liab yog golden daj, aluminium yog dawb. Koj tuaj yeem ncaj qha tev tawm ib ntu me me ntawm cov tub ntxhais hlau kom pom cov xim kom paub qhov txawv seb nws puas yog tooj liab lossis txhuas core.
Ceeb Toom: Tam sim no ntau cov xov hlau txhuas txhuas yuav raug coated nrog ib txheej ntawm cov khoom siv daj nyob rau saum npoo ntawm cov tub ntxhais hlau, feem ntau hu ua tooj liab-clad txhuas hlau, uas kuj zoo li daj. Qhov sib txawv yog raws li nram no: ib qho yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, nws yog qhov yuav tsum tau khawb tawm cov txheej txheej ntawm cov hlau, cov tub ntxhais tooj liab hlau tseem yog xim daj, thiab cov tub ntxhais txhuas hlau xaim zoo li dawb; lwm qhov yog kom hlawv nrog lub teeb, cov nplaim ntawm cov tub ntxhais tooj liab hlau yog xim xiav, thiab cov nplaim ntawm cov tub ntxhais aluminium hlau yog xim dawb.
Qhov txawv ntawm txhuas hlau thiab tooj liab hlau:
1. Kev cuam tshuam ntim ntawm tooj liab thiab txhuas hlau yog txawv;
2. Aluminium hlau kuj pheej yig;
3. Qhov hnyav ntawm aluminium hlau yog sib dua;
4. Lub zog txhua yam ntawm txhuas hlau tsis zoo;
5. Cov hlau txhuas yog qhov yooj yim heev rau oxidized ntawm qhov kawg ntawm kev sib txuas, thiab qhov kub thiab txias yuav tshwm sim tom qab oxidation ntawm kev sib txuas kawg.
6. Internal kuj ntawm tooj liab hlau yog me me. Aluminium hlau muaj ib tug loj nyob rau hauv tsis kam tshaj tooj liab hlau, tab sis nws dissipates tshav kub sai dua tooj liab hlau. Feem ntau yog vim muaj peev xwm nqa tam sim no sib txawv thiab sib txawv txhua yam muaj zog. Lub resistivity ntawm tooj liab yog 0.017 thiab cov txhuas yog 0.029. Yog li, tam sim no lub peev xwm nqa ntawm txhuas yog li 80 feem pua ntawm cov tooj liab. Lub zog txhua yam ntawm tooj liab kuj zoo dua.
