Cua turbines ua haujlwm nyob rau hauv ib puag ncig hnyav, uas feem ntau muaj qhov kub thiab txias (kwv yees li -40 degree C txog 50 degree C) thiab raug ultraviolet hluav taws xob ntau tshaj plaws. Yog li ntawd, kom ua tiav lub neej kev pab cuam, tshwj xeeb cable siv yuav tsum muaj peev xwm tiv taus qhov kub thiab txias ntawm -40 degree C thiab tiv thaiv ultraviolet hluav taws xob. Rau kev txav ntawm cov kiv cua, lub cable yuav tsum muaj qhov zoo tshaj plaws torsional thiab khoov yooj yim thiab lub vojvoog me me.
Cables kuj yuav tsum tau tiv taus roj, tub yees, roj, tshuaj corrosive thiab hnav. Yog hais tias cua teb yog onshore los yog offshore, lub cable yuav tsum tau resistant rau high salinity. Rau cov laj thawj kev nyab xeeb, ntxiv rau cov kev xav tau saum toj no, lub cable kuj tseem yuav tsum tau ua kom tsis muaj nplaim taws. Qee zaum, lwm yam khoom xws li cov pa luam yeeb tsawg, cov khoom siv xoom-halogen (LSZH) thiab EMI tiv thaiv kuj tseem yuav tsum tau.
Hauv cov ntsiab lus, cov kab hluav taws xob siv hauv cov ntawv siv cua tshuab yuav tsum tau ua raws li cov hauv qab no:
(1) Hlau: Yuav kom ua kom yooj yim tshaj plaws, nws raug pom zoo tias cov kws tsim qauv tsim tsuas yog siv ntau cov hlua ntawm cov xov tooj ntawm cov mos mos tooj liab. Nyob rau hauv kev khoov thiab winding daim ntaub ntawv, luv concentric strand siv yog siv; Nyob rau hauv daim ntawv thov ntawm torsion winding, ntev concentric stranded hlau yog siv. Cov hlau uas muaj thaj tsam ntau dua 6mm2 (10AWG) yuav tsum muaj cov qauv xaim sib txuas.
(2) Rwb thaiv tsev: txhawm rau txhawm rau ua kom qhov kub thiab txias, cov roj hmab thermoplastic (TPE), ethylene-propylene roj hmab (EPR, ib hom EPM lossis EPDM) lossis silicone roj hmab (SiR) feem ntau yog xaiv los ua cov ntaub ntawv rwb thaiv tsev los tiv thaiv ozone corrosion. thiab kev laus los ntawm cua sov. PVC / nylon rwb thaiv tsev kuj tau siv dav vim nws lub zog dielectric siab.
(3) sheath: cable sheath tuaj yeem yog thermosetting tebchaw xws li polyvinyl chloride (CPE), polychloroprene (neoprene), chloro-sulfonated polyethylene (CSPE) hluavtaws roj hmab; Nws kuj zoo ib yam li cov khoom siv thermoplastic xws li TPE, TPE-PVC alloy thiab polyurethane. Cov ntaub ntawv no tiv taus cov roj, roj thiab cov kuab tshuaj corrosion, thiab muaj qhov ua tau zoo ntawm qhov kub thiab txias. Cov cuab yeej no ua rau nws zoo tagnrho sheathing cov ntaub ntawv rau cua fais fab cables.
