Qhia tawm cov lus zais ntawm tooj liab hlau hom thiab kev ua tau zoo
Hom tooj liab hlau yog:
1. Hard tooj liab hlau
Nws yog txias ua tiav los ntawm kev kos duab hlau thiab muaj lub zog tensile siab. Nws yog tsim rau conductors ntawm overhead kis kab, tis kab thiab kev tsim kho kab.
2. Mos tooj liab hlau
Hard tooj liab hlau yog tsim los ntawm cua sov kom tshem tawm cov residual stress generated los ntawm cov txheej txheem txias. Nws yog mos thiab bendable, thiab muaj hluav taws xob conductivity. Nws yog siv los ua conductors rau kev sib txuas lus thiab fais fab cables, conductors rau hluav taws xob machinery thiab ntau yam khoom siv hauv tsev. .
3. Semi-rigid tooj liab hlau
Lub zog tensile yog nruab nrab ntawm cov tawv tooj liab hlau thiab mos tooj liab hlau, thiab yog siv los khi cov kab nyiaj siv ua haujlwm thiab xov tooj cua.
4. Tinned tooj liab hlau
Qhov saum npoo ntawm cov hlau yog tinned los ua kom cov weldability thiab tiv thaiv tus neeg xyuas pib tooj liab los ntawm corrosion thaum PVC los yog roj hmab rwb thaiv tsev extruded, thiab tiv thaiv kev laus ntawm cov roj hmab rwb thaiv tsev.
5. Square tooj liab hlau
Copper hlau nrog ib tug square lossis rectangular cross-section yog cov khoom siv rau kev tsim induction coils xws li transformers loj lossis loj motors.
6. Oxygen-dawb tooj liab hlau
Tooj hlau uas muaj cov pa oxygen tsawg dua 0.001% thiab purity siab heev. Cov ntsiab lus tooj liab yog siab dua 99.99%. Nws yuav tsis tau embritted los ntawm oxygen. Nws yog siv los ua cov xov hlau hauv lub tshuab nqus tsev, cov khoom siv hluav taws xob semiconductor, thiab cov xov hlau zoo heev.
7. Enameled hlau
Tom qab tooj liab hlau yog softened, saum npoo yog coated nrog insulating xim thiab rhuab thiab qhuav. Nws yog feem ntau muab faib ua tej yam ntuj tso cob thiab hluavtaws cob enameled hlau.
8. Copper foil hlau
Ib tug neeg xyuas pib ua los ntawm tiaj tus thiab tsis tshua muaj tooj liab xaim qhwv ib ncig ntawm fiber ntau xaim.
9. Twisting ua ntej thiab tom qab ntawd plating cov hlau
Unplated tooj liab xov hlau yog twisted thiab ces coated nrog txhuas.
10. Copper-clad steel
Feem ntau siv rau coaxial kab teeb liab kis tau tus mob (xws li kev sib txuas ntawm TV teeb thiab VCDs, sab nraum zoov TV kav hlau txais xov, kaw-circuit TV, thiab lwm yam). Cov kab tawv tawv muaj zog tensile ntau dua thiab siv los ua cov cables ntev nyob rau hauv cov cheeb tsam roob, hla cov dej ntws, thiab lwm yam. Rau cov kab hluav taws xob, cov khoom siv hluav taws xob feem ntau muab faib ua 21%, 30%, 40%, thiab lwm yam raws li cov tooj liab tuab.
Kev ua haujlwm ntawm tooj liab hlau:
1. Tus neeg xyuas pib tsis kam
Qhov tsis kam ntawm tus neeg xyuas pib yog ncaj qha proportional rau nws qhov ntev thiab inversely proportional rau nws qhov chaw hla ntu.
2. Kev coj ua
Raws li kev ua haujlwm ntawm tus qauv mos tooj liab hlau nrog qhov ntev ntawm 1m thiab qhov chaw hla ntawm 1mm2 ntawm 20 degree ntawm 1/58ohm (0.017241 ohm), nws yog hu ua 100% conductivity. Qhov ntau dua qhov kev tiv thaiv, qhov qis dua qhov conductivity, thiab ob qho tib si sib txawv.
3. Khoov tsis kam
Ib qho kawg ntawm ib lub xaim yog tsau, thiab ib qho hnyav ntxiv mus rau lwm qhov kawg kom nws vertically downward, thiab tom qab ntawd khoov rov qab mus rau 180 degrees kom txog thaum cov hlau tawg. Qhov ntau khoov, lub zog khoov zog.
4. Lub zog tawg
Hauv kev sim tensile, qhov siab tshaj plaws load hnyav lossis quab yuam siv rau cov qauv ua rau nws tawg.
5. Lub zog tensile
Thaum lub sij hawm ntsuas tensile, lub tensile tawg quab yuam ib cheeb tsam ib cheeb tsam tau ntsib thaum tus qauv tawg.
6. Ntev
Nyob rau ntawm tus txheej txheem kev ncua deb, qhov sib piv ntawm qhov ntev ntawm qhov hnoos qeev tom qab nws ncav cuag rupture mus rau nws qhov qub ntev. Cov conductors yuav muaj qhov sib txawv impedance ntawm qhov kub thiab txias. Feem ntau, 20 degree lossis 25 degree yog siv raws li tus qauv. Qhov kub thiab txias dua, qhov impedance yuav ntau dua. Hauv kev sim tensile, qhov siab tshaj plaws load hnyav lossis quab yuam siv rau cov qauv ua rau nws tawg.
