Cov txheej txheem tsim khoom rau MI cables xav tau kev tsim vaj tsev zoo vim lawv qhov kev tsim kho tsis zoo. Ua ntej, tooj liab lossis alloy conductors yog teem rau hauv qhov xav tau teeb tsa thiab kaw nyob rau hauv ib lub seamless tooj liab sheath (los yog stainless hlau los yog alloy, nyob ntawm seb daim ntawv thov). Qhov chaw nruab nrab ntawm cov conductors thiab sheath yog tom qab ntawd tau ntim nrog cov hmoov nplej siab magnesium oxide uas ua haujlwm raws li cov insulator. Cov hmoov no undergoes vibrational compaction kom ua tiav qhov ntom ntom, txheej txheej rwb thaiv tsev.
Thaum lub cable sib dhos ua tiav, nws dhau los ntawm cov txheej txheem hu ua annealing, uas muaj cov cua sov ntawm lub cable kom tshem tawm cov kev ntxhov siab uas tsim los thaum ua cov tooj liab. Annealing kuj tshem tawm cov kab ya raws los ntawm magnesium oxide, optimizing nws insulating zog.
Tom qab ntawd, lub cable tau dhau los ua cov txheej txheem ntawm kev ncab thiab nruab nrab annealing cycles. Lub stretching txo txoj kab uas hla mus rau ib tug tshwj xeeb loj. Intermediate annealing restores ductility thiab tiv thaiv conductor breakage. Txog rau qhov kawg ntawm cov txheej txheem tsim khoom, MI cable xaus feem ntau raug kaw nrog cov khoom sib txuas los tiv thaiv kev ya raws. Thiab lub tsho sab nrauv tuaj yeem coated nrog LSZH rau kev tiv thaiv ntxiv.
Thaum kawg, cov cables tiav tau raug kuaj xyuas kom paub meej tias cov rwb thaiv tsev tsis kam, lub zog dielectric, thiab lwm yam tseem ceeb ntawm cov cable ua tau raws li cov qauv kev nyab xeeb thiab cov qauv kev lag luam. Kev tswj xyuas kom zoo yog qhov tseem ceeb los xyuas kom cov cables ua tiav qhov kev xav tau ntawm cov ntawv thov.
