Cables Siv

Lub cable yog tsuas yog tsim ntawm plaub nram qab no. 1 Cov cwj pwm ua: Ua cov khoom siv hluav taws xob (tooj liab los yog txhuas). Raws li cov txheej txheem tsim ntawm cov cai rau kev nplua nuj ntawm lub cable, txhua tus tub ntxhais yuav raug tsim los ntawm kev sib tw ntawm ib tus hlau los yog ntau lub xov hlau. 2 Insulating layer: Insulating khoom siv rau cov hlua yuav tsum muaj kev ywj pheej siab, siab tawg hluav taws xob, lub dielectric tsawg thiab dielectric tsis tu ncua. Insulating cov ntaub ntawv uas siv rau hauv cov cables xws li roj-impregnated paper, polyvinyl chloride, polyethylene, crosslinked polyethylene, thiab roj hmab. Cables feem ntau tso cais los ntawm cov khoom siv hluav taws xob xws li roj xaim hluav taws xob cov kab hluav taws xob, cov kab hluav taws xob polyvinyl chloride, cov kab txuas sib txuas ntawm polyethylene, thiab cov zoo li. 3 Cov ntaub thaiv ntim pov thaiv: tiv thaiv cov kaus poom los ntawm cov khoom cua, noo, noo noo, tshuaj, lub teeb, thiab lwm yam. Rau qhov yoojyim damped yooj yim, txhuas los yog txhuas extruded sealing lub tsho yog siv. 4 lub hau npog tiv thaiv: tiv thaiv lub rooj sib tsoo ntawm kev kho mob. Kev siv cov galvanized steel, steel hlau los yog tooj liab, tooj hlau hlau qhwv ib ncig ntawm sab nraum lub tsho (hu ua armored cable), armored cable tib lub sij hawm ua hluav taws xob tiv thaiv hluav taws xob thiab tiv thaiv sab nrauv electromagnetic. Yuav kom tsis txhob txhuam cov hlau thiab steel hlau nyob ib ncig ntawm cov xov xwm puag ncig, lawv feem ntau coated nrog asphalt los yog qhwv rau hauv txheej ntawm impregnated jute los yog extruded polyethylene, PVC tsho.

Peb muaj cov cua kub ntsws hlab ntsha, xws li cov cua kub ntsws hlawv hluav taws xob / phab ntsa phab ntsa ntswj hlawv / phab ntsa phab ntsa cua kub yawm hlawv / pvc kub yaug hlab hlaub thiab lwm yam. Yog tias koj xav siv cable, peb yuav qhia nws raws li koj qhov kev nthuav dav cov ntaub ntawv.
