Wrapping thiab filling cov ntaub ntawv
Wrapping yog hais txog cov txheej txheem ntawm wrapping ntau yam hlau los yog cov ntaub ntawv uas tsis yog hlau rau cov tub ntxhais cable nyob rau hauv daim ntawv ntawm daim kab xev los yog hlau. Wrapping yog cov txheej txheem siv dav, thiab cov txheej txheem rwb thaiv tsev, thaiv thiab tiv thaiv txheej txheej yog siv, suav nrog rwb thaiv tsev wrapping, wrapping refractory daim kab xev, hlau shielding, cable forming, armor, braiding thiab lwm yam.
(1)Daim kab xev tooj liab, tooj liab-yas composite daim kab xev
Copper daim kab xev thiab tooj liab-yas daim kab xev muaj lawv cov kev siv nyob rau hauv fais fab cables. Copper daim kab xev yog tsuas yog siv rau hlau shielding txheej, uas plays lub luag hauj lwm ntawm conduction tam sim no thiab hluav taws xob teb shielding, thiab yuav tsum muaj siab purity, zoo mechanical zog thiab zoo li zoo. Copper-plastic composite daim kab xev yog ua los ntawm tooj liab daim kab xev, ua ke nrog cov yas zaj duab xis, siv rau kev sib txuas lus cable shielding, yuav tsum tau xim xim, du nto thiab tsis muaj kev puas tsuaj, muaj zog tensile zog, elongation thiab conductivity.
(2) Yas coated aluminium daim kab xev
Yas coated aluminium daim kab xev yog cov khoom tseem ceeb rau hluav taws xob fais fab, roj av, tshuaj thiab lwm yam kev lag luam ntawm cable, vim nws zoo heev waterproof thiab ya raws rwb thaiv tsev kev ua tau zoo. Nws yog qhwv los yog longitudinally, thiab nruj nreem khi nrog polyethylene sheath los ntawm kev kub siab thiab kub siab los tsim ib qho kev sib xyaw ua ke. Yas coated aluminium daim kab xev muaj cov qauv xim, du nto, superior mechanical zog, siab tensile zog thiab elongation kuj.
(3) Hlau daim kab xev, Hlau hlau
Vim tias lawv cov khoom siv zoo heev, cov kab xev hlau thiab cov hlau hlau tau siv dav hauv cov khaubncaws sab nraud povtseg thiab lwm yam khoom siv thauj khoom hauv cables uas ua lub luag haujlwm tiv thaiv txhua yam. Hlau daim kab xev yuav tsum tau galvanized, tinned los yog pleev xim rau kom txhim khu corrosion kuj. Cov txheej txheej galvanized tuaj yeem ua rau hauv qhov chaw thiab muaj kev ruaj ntseg siab, thaum nws tuaj yeem txi nws tus kheej los tiv thaiv cov txheej steel thaum nws ntsib dej. Raws li cov khoom siv armored, steel hlau yog qhov tseem ceeb hauv lub sijhawm tseem ceeb xws li hla dej hiav txwv thiab dej hiav txwv, ntev-ntev overhead nteg. Txhawm rau txhim kho corrosion kuj ntawm steel hlau, steel hlau feem ntau galvanized los yog coated nrog high-density polyethylene. Stainless acid-resistant steel hlau muaj ntau dua corrosion kuj thiab mechanical zog, haum rau tshwj xeeb hlau thiab cable.
Non-woven npuag daim kab xev kuj hu ua nonwoven npuag, uas yog ua los ntawm hluavtaws fiber ntau raws li lub ntsiab lub cev los ntawm cov nplaum nplaum, uas yog feem ntau siv polyester fiber. Haum rau qhwv los yog hauv ob sab phlu ntawm cables. Cov tsos ntawm fiber ntau faib yog sib xws, tsis muaj pwm, nyuaj impurities thiab qhov, tsis muaj kab nrib pleb nyob rau hauv dav, qhuav thiab tsis ntub.
(5) Fireproof daim kab xev
Daim kab xev hluav taws xob tau muab faib ua ob pawg: daim kab xev hluav taws xob thiab cov nplaim hluav taws xob, uas tuaj yeem tswj cov hluav taws xob rwb thaiv tsev hauv qab nplaim taws, xws li mica daim kab xev thiab ceramic refractory puas daim kab xev; Flame-retardant daim kab xev, xws li iav ribbon, tuaj yeem tiv thaiv kev sib kis ntawm nplaim taws. Lub refractory mica daim kab xev nrog mica ntawv raws li nws cov tub ntxhais muaj hluav taws xob zoo heev thiab kub tsis kam.
Ceramic refractory composite sawb ua tiav cov nplaim hluav taws kub hnyiab los ntawm kev tua hluav taws rau hauv ceramic plhaub rwb thaiv tsev txheej. iav fiber ntau daim kab xev nrog nws cov tsis-combustible, tshav kub resistant, hluav taws xob rwb thaiv tsev thiab lwm yam ntxwv, feem ntau siv nyob rau hauv hluav taws kub retardant cable reinforcement txheej, muab ib tug muaj zog guarantee rau cable kev ruaj ntseg.
Cov dej thaiv kab xev yog tsim los ntawm ob txheej ntawm polyester fiber tsis-woven npuag thiab cov khoom nqus tau zoo heev. Thaum dej infiltrates, cov khoom nqus tau nrawm nrawm kom sau cov kab sib txawv, tiv thaiv kom tsis txhob muaj dej ntxiv thiab nthuav tawm. Feem ntau siv cov ntaub ntawv nqus tau zoo xws li carboxymethyl cellulose, thiab lwm yam, uas muaj cov dej zoo heev thiab kev tuav dej thiab tsim nyog rau kev tiv thaiv dej tiv thaiv ntawm cables.
(7) Cov khoom ntim khoom
Cable filling cov ntaub ntawv muaj ntau haiv neeg, thiab qhov tseem ceeb yog ua kom tau raws li qhov yuav tsum tau muaj ntawm qhov kub thiab txias, tsis yog-hygroscopic thiab tsis muaj kev phiv tshuaj tiv thaiv kab mob. Polypropylene hlua yog dav siv vim nws ruaj khov lub cev thiab tshuaj lom neeg zog, siab mechanical zog thiab zoo kub kuj. Prefabricated yas muab tub lim strips yog tsim los ntawm kev rov ua dua cov yas pov tseg, uas yog ib puag ncig tus phooj ywg thiab kev lag luam. Nyob rau hauv cov nplaim hluav taws thiab hluav taws-resistant cables, asbestos hlua yog dav siv rau nws zoo heev tshav kub tsis kam thiab nplaim retardant, txawm hais tias nws siab ceev tsub kom tus nqi.
