Txoj kab uas hla ntawm qhov siab -voltage conductor feem ntau yog ob peb zaug ntawm qhov qis -voltage conductor. Txhawm rau ua kom yooj yim dua thiab khoov ntawm qhov siab -voltage conductor, tus neeg xyuas pib nrog lub interface loj dua yog tsim los ntawm kev sib tw ntau cov xov hlau uas muaj cov kab me me. Cov tub ntxhais hlau tso tseg los ntawm ntau cov xov hlau ib leeg muaj qhov yooj yooj yim thiab loj curvature. Thaum cov tub ntxhais hlau yog khoov, sab hauv thiab sab nraud ntawm cov kab nruab nrab ntawm cov tub ntxhais hlau tuaj yeem txav mus los sib npaug, thiab cov yas deformation ntawm tus neeg xyuas pib yuav tsis tshwm sim thaum khoov, yog li qhov softness ntawm cov tub ntxhais hlau. Qhov kev ua tau zoo thiab kev ruaj ntseg zoo heev. Yog li ntawd, cov hlua hluav taws xob tsheb, tshwj xeeb tshaj yog siab - cov xaim hluav taws xob, feem ntau yog tsim los ntawm cov khoom siv sib txuas.
Daim ntawv twisting ntawm cov tub ntxhais yuav muab faib ua ob hom, tsis tu ncua twisting thiab irregular twisting.
(1) Tsis tu ncua twist
Cov xov hlau muaj qhov tsis tu ncua, concentric, thiab cov khaubncaws sab nraud povtseg yog twisted nyob rau hauv cov lus qhia sib txawv rau hauv ib txwm twists.
Tsis tas li ntawd, nws tuaj yeem muab faib ua ib txwm stranding thiab txawv txav tsis tu ncua stranding. Cov yav tas yog hais txog kev sib tw tsis tu ncua ntawm cov xov hlau nrog cov kab sib txawv ntawm cov khaubncaws sab nraud povtseg, thiab yav dhau los yog hais txog cov xov hlau uas muaj tib txoj kab uas hla.
Kev sib tw tsis tu ncua kuj tseem tuaj yeem muab faib ua qhov yooj yim tsis tu ncua twisting thiab sib xyaw ua ke tsis tu ncua. Lub tom kawg yog hais txog qhov tseeb hais tias cov xov hlau uas ua rau cov kev sib tw tsis tu ncua tsis yog ib leeg, tab sis cov xov hlau nyias nyias tau sib tw rau hauv cov hlua raws li txoj cai, thiab tom qab ntawd twisted rau hauv cov xov hlau. Cov tub ntxhais, qhov kev sib tw no feem ntau yog siv los txav cov tub ntxhais ntawm cov roj hmab insulated cable los txhim kho nws qhov yooj.
(2) Kev tsis sib haum xeeb
Hais txog qhov twisting ntawm tag nrho cov constituent xov hlau nyob rau hauv tib txoj kev.
Lub stranding ntawm cov tub ntxhais tseem yog tsim los rau lwm yam txheej txheem tsis, xws li stranding pitch, stranding coefficient, stranding kev taw qhia, stranding txoj cai, thiab lwm yam.
Ua raws li cov txheej txheem tsim khoom thiab cov txheej txheem yuav tsum tau ua, txoj kev sib tw ntawm high -voltage wires rau lub tsheb hluav taws xob feem ntau yog qhov qub thiab tsis tu ncua twisting, uas yog qhov zoo rau kev siv tshuab thiab kev tsim khoom.
