ETFE Insulated Hlau

Muaj nuj nqi:Tus neeg xyuas pib yog ib feem ntawm cov hlau thiab cable uas xa hluav taws xob (sib nqus) lub zog, cov ntaub ntawv thiab paub txog cov haujlwm tshwj xeeb ntawm kev hloov hluav taws xob hluav taws xob.

Khoom siv:Muaj cov tsis muaj coated conductors, xws li tooj liab, txhuas, tooj liab alloy, aluminium alloy; hlau-coated conductors, xws li tinned tooj liab, silver-plated tooj liab, nickel-plated tooj liab; hlau-clad conductors, xws li tooj liab-clad steel, tooj liab-clad aluminium, aluminium clad steel, thiab lwm yam.

Muaj nuj nqi:Cov txheej txheej insulating yog qhwv ib ncig ntawm tus neeg xyuas pib lossis cov txheej txheem ntxiv ntawm tus neeg xyuas pib (xws li refractory mica daim kab xev), thiab nws txoj haujlwm yog cais tus neeg xyuas pib los ntawm kev coj tus cwj pwm sib txuas thiab tiv thaiv cov dej ntws tam sim no.

Cov khoom siv feem ntau siv rau extruded rwb thaiv tsev yog polyvinyl chloride (PVC), polyethylene (PE), cross-linked polyethylene (XLPE), tsis tshua muaj pa taws halogen-dawb nplaim retardant polyolefin (LSZH / HFFR), fluoroplastics, thermoplastic elasticity (TPE), silicone roj hmab (SR), ethylene propylene roj hmab (EPM / EPDM), thiab lwm yam.

Muaj nuj nqi:Lub shielding txheej siv nyob rau hauv cov khoom siv hlau thiab cable yeej muaj ob lub ntsiab lus sib txawv kiag li.

Ua ntej, cov qauv ntawm cov xov hlau thiab cables uas xa cov hluav taws xob ntau zaus (xws li xov tooj cua zaus, hluav taws xob cables) lossis cov tsis muaj zog tam sim no (xws li cov teeb liab cables) hu ua electromagnetic shielding. Lub hom phiaj yog los thaiv cov kev cuam tshuam ntawm cov hluav taws xob sab nraud, lossis tiv thaiv cov teeb liab siab zaus hauv cov kab hluav taws xob los ntawm kev cuam tshuam nrog lub ntiaj teb sab nraud, thiab tiv thaiv kev sib cuam tshuam ntawm cov hlau khub.

Qhov thib ob, cov qauv ntawm nruab nrab thiab siab voltage fais fab cables kom sib npaug ntawm qhov hluav taws xob ntawm tus neeg xyuas pib nto los yog qhov chaw insulating yog hu ua hluav taws xob tiv thaiv. Kev hais lus nruj me ntsis, kev tiv thaiv hluav taws xob tsis tas yuav muaj kev ua haujlwm ntawm "shielding", tab sis tsuas yog ua lub luag haujlwm ntawm homogenizing hluav taws xob teb. Cov ntaub thaiv npog uas qhwv ib ncig ntawm lub cable feem ntau yog hauv av.

Electromagnetic shielding qauv thiab cov ntaub ntawv

① Braided shielding:Feem ntau siv liab qab tooj liab hlau, tin-plated tooj liab hlau, nyiaj-plated tooj liab hlau, txhuas-magnesium alloy hlau, tooj liab ca daim kab xev, nyiaj-plated tooj liab ca daim kab xev, thiab lwm yam. ;

② Copper daim kab xev shielding:Siv cov ntaub nplaum mos los npog lossis qhwv ntsug sab nraum lub tub ntxhais cable;

③ Hlau composite daim kab xev shielding:Siv aluminium ntawv nyiaj Mylar daim kab xev los yog tooj liab ntawv nyiaj Mylar daim kab xev los qhwv ib ncig los yog vertically qhwv cov hlau khub los yog cable core;

④ Comprehensive shielding:Daim ntawv thov dav siv los ntawm ntau hom kev tiv thaiv.Piv txwv li, qhwv (1-4) nyias tooj liab xov hlau vertically tom qab qhwv nrog txhuas ntawv nyiaj Mylar daim kab xev. Cov xov tooj tooj liab tuaj yeem ua rau muaj kev cuam tshuam ntawm kev tiv thaiv;

⑤ Separate shielding + zuag qhia tag nrho shielding:Txhua tus khub hlau los yog pawg ntawm cov xov hlau yog thaiv los ntawm txhuas ntawv nyiaj Mylar daim kab xev los yog tooj liab hlau braided nyias, thiab tom qab ntawd tag nrho cov shielding qauv yog ntxiv tom qab cabling;

⑥ Wrapping shielding:Siv nyias tooj liab hlau, tooj liab ca daim kab xev, thiab lwm yam los qhwv ib ncig ntawm lub insulated hlau core, hlau khub los yog cable core.

Lub luag haujlwm ntawm lub sheath yog los tiv thaiv lub cable, thiab cov tub ntxhais yog los tiv thaiv lub rwb thaiv tsev. Vim qhov kev hloov pauv ib puag ncig, kev siv thiab cov neeg siv khoom xav tau. Yog li ntawd, hom, cov qauv qauv thiab kev ua tau zoo ntawm cov qauv sheathing kuj sib txawv, uas tuaj yeem muab faib ua peb pawg:

Ib qho yog los tiv thaiv cov xwm txheej sab nraud, qee lub sijhawm cov neeg kho tshuab, thiab cov txheej txheem kev tiv thaiv dav dav uas yuav tsum muaj kev sib khi dav dav (xws li tiv thaiv kev nkag ntawm cov dej vapor thiab cov pa phem); Yog hais tias muaj ib tug loj mechanical sab nraud quab yuam los yog dais lub luj ntawm cable, yuav tsum muaj ib tug tiv thaiv txheej txheem ntawm cov hlau armor txheej; qhov thib peb yog cov txheej txheem tiv thaiv nrog cov kev cai tshwj xeeb.
