Scope
Cov cables raug tsim thiab sim ua raws li IEC60502 Fais Fab Cables nrog Extruded Rwb thaiv tsev thiab lawv cov khoom siv rau cov ntsuas hluav taws xob ntawm 1kV (Um1.2 kV) txog 30kV (Um 36kV).
Kev tsim kho thiab khoom siv
1) Tus coj
Cov neeg ua haujlwm feem ntau yog cov chav kawm 2 ntawm kev cog lus cicular lossis lub voj voog tus qauv ntawm tooj liab lossis txhuas.
2) Conductor Screen
Tag nrho cov kab hluav taws xob ntawm cov ntsuas hluav taws xob siab tshaj 1.8 / 3kV yog muab nrog kev tshuaj ntsuam xyuas tus neeg xyuas pib uas tsis yog kev xav thiab muaj cov kab xev ib nrab lossis ib txheej ntawm extruded semi-conducting compound, los yog kev sib xyaw ntawm ob.
3) rwb thaiv tsev
Rwb thaiv tsev yog ib txheej ntawm extruded cross-linked polyethylene (XLPE).
4) Rwb thaiv tsev Screen
Rau cov kab hluav taws xob ntawm qhov ntsuas hluav taws xob siab tshaj 1.8 / 3kV, kev tshuaj ntsuam xyuas hluav taws xob muaj cov khoom tsis yog xim hlau ib nrab ua ke nrog cov txheej hlau thiab muaj cov kab xev semi-conducting los yog txheej ntawm extruded semi-conducting compound .. Cov rwb thaiv tsev extruded npo yog ib txwm dawb strippable (yooj yim tshem tawm) hom tab sis tuaj yeem muab nrog kev sib koom ua ke raws li kev thov.
Cov khoom siv hlau feem ntau yog siv rau ntawm tus kheej cores rau qhov ntsuas hluav taws xob siab tshaj 1.8 / 3kV thiab ntawm cov tub ntxhais sib dhos rau qhov ntsuas hluav taws xob 1.8 / 3kV thiab muaj cov kab xev dawb annealed tooj liab. los yog tooj liab daim kab xev npo ib txheej ntawm tooj liab hlau, txhuas hlau los yog corrugated aluminium sheath tuaj yeem muab tau raws li qhov kev thov.
5) Sab hauv los yog sib cais Sheath (rau armored cables)
Ib txheej ntawm PVC puab npog yog siv nyob rau hauv lub armor, yog tias tsis muaj qhov screen.
Thaum kev tshuaj ntsuam xyuas hlau thiab cov cuab yeej muaj cov hlau sib txawv, ib qho extruded cais sheath ntawm PVC yog muab nyob rau hauv thiaj li yuav cais cov sib txawv hlau.
6) Hlau Armor
Cov armor, yog tias xav tau, muaj ib txheej ntawm cov xov hlau puag ncig lossis ob daim kab xev ntawm galvanized steel lossis aluminium lossis lwm yam hlau tsis sib nqus. Ib leeg tub ntxhais cables feem ntau yog armored nrog txhuas (lwm yam uas tsis yog-sib nqus hlau), vim hais tias tsis yog-sib nqus armor yog ib qho tseem ceeb rau ib tug tub ntxhais cable siv nyob rau hauv AC Circuit Court.
7) Outer Sheath
Tag nrho cov cable yog ib txwm muab nrog ib qho extruded PVC tawm sheath, xim dub (chav kawm ST2). Lwm cov ntaub ntawv tuaj yeem muaj raws li kev thov, xws li PE, polyethylene, nplaim hluav taws kub lossis hluav taws kub retardant PVC thiab lwm yam.
8) Core Identification
Ntau cov conductors raug txheeb xyuas raws li IEC60502.
PobKhoom siv :
Ntoo nruas, steel ntoo nruas (fumigation)
Cable ntev hauv txhua lub nruas: 500m / 1000m lossis raws li qhov xav tau ntawm cable ntev.
Cim npe nrov: 26/35kv kab
