FAQ
Q: Koj puas xav tau cov txheej txheem ntxiv los tiv thaiv koj cov cables los ntawm kev laus?
Q: Nws puas tseem ceeb yog tias lub cable siv nyob rau hauv qhov chaw kub?
1. Cov khoom siv rwb thaiv tsev
Qhov kub thiab txias ib puag ncig yuav ua rau kom lub thermal aging ntawm cov khoom siv rwb thaiv tsev, ua rau cov txheej rwb thaiv tsev kom tawv, tawg lossis txawm tias tsis ua haujlwm, yog li cuam tshuam rau lub neej ntawm lub cable. Hauv cov ntawv thov kub kub, cov khoom siv hluav taws xob kub tiv thaiv hluav taws xob xws li cross-linked polyethylene (XLPE) lossis chloroprene roj hmab (CR) yuav tsum tau siv, uas muaj thermal stability ntau dua thiab tiv thaiv kev laus.
2. Txo lub peev xwm nqa tam sim no
Nyob rau hauv ib puag ncig kub, qhov kev tiv thaiv ntawm cable nce, ua rau muaj kev kub ntxhov ntau ntxiv, uas cuam tshuam rau lub peev xwm nqa tam sim no ntawm cable. Feem ntau hais lus, lub peev xwm nqa tam sim no ntawm cable yuav raug txo qis hauv qhov chaw kub. Lub derating yam ntawm lub cable tam sim no nqa peev xwm yuav tsum raug xa mus rau, thiab ib tug thicker cable yuav tsum tau tiv nrog tib yam tam sim no thov.
3. Kev pheej hmoo ntawm overheating
Qhov kub thiab txias ib puag ncig tuaj yeem yooj yim ua rau cov kab hluav taws xob kub siab tshaj nws qhov siab tshaj plaws kev ua haujlwm kub, ua rau muaj qhov tshwm sim overheating. Qhov no tuaj yeem ua rau muaj kev puas tsuaj rau cov txheej txheem rwb thaiv tsev lossis ua rau muaj kev phom sij luv luv. Nws yog ib qho tsim nyog los xyuas kom meej tias lub cable tau muab tso rau hauv qhov chaw zoo thaum tshav kub kub dissipation, thiab tsis txhob bundling los yog nteg ntau lub cables ntau heev.
4. Degradation ntawm cov ntaub ntawv sheath
Nyob rau hauv qhov kub thiab txias, cov ntaub ntawv sheath ntawm cable (xws li PVC) yuav maj mam poob elasticity thiab durability, thiab ces tawg los yog nkig. Nws raug nquahu kom siv cov ntaub qhwv nrog cov cua sov zoo dua, xws li chloroprene roj hmab lossis silicone roj hmab, nyob rau hauv qhov chaw kub kub kom ntev lub neej ntawm cov hlua sab nrauv.
5. Thermal expansion thiab mechanical stress
Qhov kub thiab txias yuav ua rau thermal expansion ntawm lub cable, uas yuav ua rau cov neeg kho tshuab kev ntxhov siab hloov, tshwj xeeb tshaj yog thaum lub installation qhov chaw me me thiab muaj ntau cov ntsiab lus kho. Thaum txhim kho, koj tuaj yeem txiav txim siab khaws qee qhov thermal expansion margins thiab siv cov ntaub ntawv nrog qee qhov kev hloov pauv kom tsis txhob cuam tshuam ntawm thermal expansion thiab contraction.
6. luv Circuit Court thiab overload muaj peev xwm
Nyob rau hauv ib puag ncig kub, lub luv luv-circuit kam rau ua ntawm lub cable yuav raug txwv. Yog li ntawd, thaum tsim kev tiv thaiv luv luv, qhov cuam tshuam ntawm qhov kub thiab txias yuav tsum tau txiav txim siab kom tsis txhob teeb tsa qhov luv luv luv tam sim no.
Cov kev ntsuas uas cov cables tuaj yeem coj mus rau hauv qhov chaw kub:
1. Xaiv cov kab hluav taws xob kub uas tiv thaiv kab mob los yog txhim kho cov kab hluav taws xob hluav taws xob (xws li kev txhim kho hauv qhov chaw txias lossis ua kom muaj cua).
2. Tsim cov cable loj raws li cov chaw tsim khoom cable derating yam.
3. Siv lub tsho tsim nyog thiab cov ntaub ntawv rwb thaiv tsev kom ncua kev laus thiab txhim kho qhov kub thiab txias.
Q: Cov kab hluav taws xob puas ua paug rau ib puag ncig?
