Hauv cov qauv tsim qauv tshiabhluav taws-resistantCables,Hla-Txuas Polyethylene (XLPE) insulatedCables tau siv dav. Lawv nthuav tawm cov khoom hluav taws xob zoo, cov khoom siv neeg siv tshuab, thiab ib puag ncig ruaj khov. Tsiag ntawv los ntawm kev ua haujlwm siab kub, kis loj kis tau, thiab kev teeb tsa yooj ywm thiab txij nkawm, lawv sawv cev rau kev txhim kho ntawm cov cable tshiab.
1. Cable Tus Qauv Coj
Cov Qauv Coj thiab Cov Qauv: Tus thawj coj qauv tau txais tus kiv cua-qauv thib ob ntawm cov qauv kev coj ua Compact Hauv cov txheej txheem tsis tu ncua, txheej hauv nruab nrab muaj ntawm ib lub xaim, txheej thib ob muaj rau cov xov hlau, thiab cov txheej txheem txuas ntxiv sib txawv ntawm rau cov xov hlau. Cov txheej txheej sab nraud yog sab laug-tes tso tseg, thaum lwm cov txheej txheem nyob sib nrug sib npaug. Cov xov hlau yog ncig ncig thiab ntawm sib npaug sib luag, ua kom muaj kev ruaj khov nyob rau hauv cov qauv stranding no. Compact qauv: los ntawm kev ua haujlwm, tus neeg xyuas pib ua kom du, tsis txhob muaj kev pom ntawm thaj teb hluav taws xob. Ib txhij, nws tiv thaiv cov ntaub ntawv ib nrab ua los ntawm kev nkag mus hauv cov hlau core kev sib cais, ua tiv thaiv cov dej noo noo thiab ua kom muaj qee yam ntawm kev hloov zuj zus. Cov neeg taug kev muaj peev xwm zoo siv tau yooj yim, kev ntseeg tau, thiab muaj zog siab.
2. Cable Rwb Thaivwb Txheej TxheejKev tsim ua
Lub luag haujlwm ntawm cov txheej txheem rwb thaiv tsev yog kom ntseeg tau tias qhov kev ua tau zoo hluav taws xob thiab tiv thaiv kev ntws ntawm cov neeg saib xyuas los ntawm kev xau sab nraud. Ib qho qauv extrusion yog ua haujlwm, nrogXLPE Khoomxaiv rau rwb thaiv tsev. XLPE muaj kev ua tau zoo tshaj rau polyethylene, muaj cov hluav taws xob hluav taws xob tsis sib xws (ε) thiab qis dielectric ploj tau tangent (tgΔ). Nws yog qhov zoo tshaj plaws cov khoom siv rwb thaiv tsev zoo tshaj plaws. Nws ntim tsis kam coefficient thiab tawg teb lub peev xwm tseem tsis tau hloov dua tshiab txawm tias tom qab xya hnub ntawm kev nkag siab hauv dej. Li no, nws yog dav siv hauv cable rwb thaiv tsev. Txawm li cas los xij, nws muaj qhov tsawg melting point. Thaum siv nyob rau hauv cables, overcurrent los yog luv-taws-circuitity yuav ua rau muaj qhov kub, ua rau kev softening thiab deformation ntawm polyethylene, uas ua rau rwb thaiv tsev puas tsuaj. Txhawm rau khaws qhov zoo ntawm polyethylene, nws undergoes hla kev sib txuas, ua rau muaj kev ntxhov siab ib puag ncig, ua cov khoom siv rwb thaiv tsev zoo tshaj plaws.
3. Cable stranding thiab qhwv tsim
Lub hom phiaj ntawm Cable Stranding thiab qhwv yog los tiv thaiv cov rwb thaiv tsev, thiab tiv thaiv kom tsis txhob muaj lub ntsej muag xoob thiab muab tso rau xoob xoob thiab ua kom muaj kev sib dhos ntawm cov tub ntxhais. Tusnplaim-retardant wrapping sivmuab qee cov nplaim hluav taws-retardant.
Cov ntaub ntawv rau cable stranding thiab qhwv: qhwv cov khoom siv yog lub ntsej muag zoo-retardantTsis-Woven FabricSiv tawv, nrog lub zog tensile thiab nplaim taws retardancy Performance index tsis muaj tsawg dua 55% cov pa oxygen. Tus muab tub lim cov ntaub muag khoom siv-retardant inorganic ntawv (cov hlua roj av), uas yog mos, nrog cov pa oxygen uas tsis muaj tsawg dua 30%. Yuav tsum muaj rau cable stranding thiab Wrapping muaj xws li xaiv qhov dav ntawm cov tub ntxhais lub cheeb tsam thiab lub ces kaum kev, raws li qhov kev sib tshooj lossis cov ntaub qhwv. Daim ntaub qhwv tau sab laug. Cov tawv ntoo-nplaim taws-retardant yuav tsum rau cov nplaim taws-retardant. Cov cua sov tsis kam ntawm cov chaw ua haujlwm yuav tsum phim lub cable ua haujlwm kub, thiab nws cov lus yuav tsum tsis cuam tshuam nrog tusrwb thaiv tsev cov ntaub ntawv.Nws yuav tsum tau tshem tawm yam uas tsis muaj kev puas tsuaj rwb thaiv tsev.
