Product Description

Insulated PVC sheathed fais fab cable, Cov cables yog siv rau kev xa hluav taws xob thiab kev faib khoom nrog cov ntsuas hluav taws xob ntawm 0.6/1, 1.8/3, 3.6/6, 6/10, 8.7/10, 8.7/15, 12/20, 21/ 35, 26/35 KV TSI.
1. XLPE insulated, PVC sheathed fais fab cables (YJV, YJLV) yog tsim rau sab hauv tsev, tunnels, kav, thiab faus rau hauv av (tsis raug rau txhua yam quab yuam)
2. XLPE insulated, steel daim kab xev armored PVC sheathed fais fab cables (YJV22, YJLV22) yog tsim rau sab hauv tsev, qhov, cov yeeb nkab nkag, thiab faus rau hauv av
3. XLPE insulated, steel hlau armored PVC sheathed fais fab cables (YJV32, 42, YJLV32, 42) yog haum rau shafts, dej, qhov chaw nrog poob, thiab muaj peev xwm tiv taus sab nraud quab yuam)

Cov lus qhia rau kev siv

A) thaum lub sijhawm ua haujlwm ntawm cov cable, qhov siab tshaj plaws tus neeg xyuas pib yuav tsum yog 70 ℃ rau PVC rwb thaiv tsev thiab 90 ℃ rau XLPE rwb thaiv tsev.
B) Qhov kub siab tshaj plaws ntawm tus neeg xyuas pib thaum lub sijhawm luv luv (qhov ntev tshaj plaws tsis pub tshaj 5 vib nas this):
PVC rwb thaiv tsev - 160 ℃ rau tus neeg xyuas pib hla ntu ≤300mm2, 140 ℃ rau tus neeg xyuas pib hla ntu> 300mm2;Crosslinked PVC rwb thaiv tsev ntawm 250 ℃.
C) Thaum tso cov cables, qhov kub ntawm qhov chaw yuav tsum tsis pub tsawg tshaj 0 ℃, thiab qhov tsawg kawg nkaus tso cai rau lub vojvoog yog raws li hauv qab no:
Ib leeg tub ntxhais cable: unarmored 20D, armored 15D
Multi-core cable: 15D rau unarmored, 12D rau armored
Qhov twg: D- qhov tseeb sab nraud ntawm cable.
D) Cable tawg quab yuam:
Aluminium tub ntxhais cable: 40 × S (N)
Copper tub ntxhais cable: 70 × S (N)
Lus Cim: S yog tag nrho cov ntu ntu ntawm tus neeg xyuas pib

Khoom qauv nta

1. Muaj qhov kub thiab txias tsis kam: XLPE rwb thaiv tsev siv tshuaj lom neeg los yog lub cev txoj hauv kev los hloov cov qauv ntawm polyethylene molecules rau hauv cov qauv peb-seem.Cov qauv kev sib txuas ntawm peb sab muaj qhov ua kom sov zoo thiab tuaj yeem siv rau kev ua haujlwm ntev ntawm qhov kub ntawm 90 degrees Celsius, lub neej ntev tuaj yeem ntev li 40 xyoo.
2. Nws muaj kev rwb thaiv tsev zoo: kev ua haujlwm ntawm polyethylene tsis tsuas yog khaws cov rwb thaiv tsev ntawm kev sib txuas ntawm polyethylene, tab sis kuj tseem muaj kev txhim kho ntxiv hauv rwb thaiv tsev.
3. Cov khoom siv kho tshuab siab: hardness, nruj, hnav tsis kam thiab cuam tshuam tsis kam tau raug txhim kho
4. Tshuaj tiv thaiv: XLPE nws tus kheej muaj zog acid thiab alkali tsis kam thiab roj kuj
5. Kev tiv thaiv ib puag ncig: Txij li cov khoom ntawm kev sib txuas ntawm polyethylene combustion yog dej thiab cov pa roj carbon dioxide, ib puag ncig muaj kuab paug tsawg, thiab nws ua tau raws li cov kev cai ntawm kev nyab xeeb hluav taws.
6. Qhov siab tshaj plaws ntsuas kub ntawm tus neeg xyuas pib yog 90 ° C, thiab qhov kub siab tshaj plaws ntawm tus neeg xyuas pib thaum lub sij hawm luv luv (qhov ntev tshaj plaws tsis pub tshaj 5S) tsis tshaj 250 ° C.
