Cov qauv yooj yim ntawm cov hlau thiab cable suav nrog tus neeg xyuas pib, rwb thaiv tsev, tiv thaiv, hnab thiab lwm yam.
1. Tus Neeg Coj
Kev Ua Haujlwm: Tus neeg coj hluav taws xob yog ib feem ntawm cov hlau thiab cov hlua uas xa cov hluav taws xob (sib nqus), cov ntaub ntawv thiab ua tiav cov haujlwm tshwj xeeb ntawm kev hloov pauv hluav taws xob electromagnetic.
Khoom siv: Muaj cov hlau tsis muaj txheej, xws li tooj liab, txhuas, tooj liab alloy, txhuas alloy; hlau-coated conductors, xws li tooj liab tinned, nyiaj-plated tooj liab, nickel-plated tooj liab; hlau-clad conductors, xws li tooj liab-clad hlau, tooj liab-clad txhuas, txhuas clad hlau, thiab lwm yam.
2. Kev rwb thaiv tsev
Kev Ua Haujlwm: Cov txheej insulating yog qhwv ib ncig ntawm tus neeg xyuas pib lossis txheej ntxiv ntawm tus neeg xyuas pib (xws li daim kab xev mica refractory), thiab nws txoj haujlwm yog cais tus neeg xyuas pib los ntawm kev nqa lub zog sib xws thiab tiv thaiv kom tsis txhob muaj hluav taws xob xau.
Cov ntaub ntawv siv rau kev rwb thaiv tsev extruded yog polyvinyl chloride (PVC), polyethylene (PE), cross-linked polyethylene (XLPE), low-smoke halogen-free flame retardant polyolefin (LSZH/HFFR), fluoroplastics, thermoplastic elasticity (TPE), silicone roj hmab (SR), ethylene propylene roj hmab (EPM/EPDM), thiab lwm yam.
3. Kev Tiv Thaiv
Kev Ua Haujlwm: Cov txheej tiv thaiv siv rau hauv cov hlau thiab cov khoom siv cable yeej muaj ob lub tswv yim sib txawv kiag li.
Ua ntej, cov qauv ntawm cov xov hlau thiab cov cables uas xa cov nthwv dej electromagnetic siab (xws li xov tooj cua zaus, cov cables hluav taws xob) lossis cov hluav taws xob tsis muaj zog (xws li cov cables teeb liab) hu ua electromagnetic shielding. Lub hom phiaj yog los thaiv kev cuam tshuam ntawm cov nthwv dej electromagnetic sab nraud, lossis tiv thaiv cov teeb liab siab hauv cov cable los ntawm kev cuam tshuam rau lub ntiaj teb sab nraud, thiab tiv thaiv kev cuam tshuam ntawm cov khub hlau.
Qhov thib ob, cov qauv ntawm cov xov hluav taws xob nruab nrab thiab siab kom sib npaug lub zog hluav taws xob ntawm qhov chaw ntawm tus neeg xyuas hluav taws xob lossis qhov chaw rwb thaiv tsev hu ua kev tiv thaiv hluav taws xob. Hais lus nruj me ntsis, kev tiv thaiv hluav taws xob tsis xav tau lub luag haujlwm ntawm "kev tiv thaiv", tab sis tsuas yog ua lub luag haujlwm ntawm kev sib xyaw lub zog hluav taws xob. Lub ntaub thaiv uas qhwv ib ncig ntawm lub cable feem ntau yog grounded.
* Cov qauv thiab cov ntaub ntawv tiv thaiv electromagnetic
① Braided shielding: feem ntau siv cov hlau tooj liab liab qab, hlau tooj liab tin-plated, hlau tooj liab nyiaj-plated, hlau txhuas-magnesium alloy, daim kab xev tooj liab tiaj tus, daim kab xev tooj liab nyiaj-plated, thiab lwm yam kom raug braided sab nraum lub hauv paus insulated, khub hlau lossis cable core;
② Daim kab xev tooj liab tiv thaiv: siv daim kab xev tooj liab mos los npog lossis qhwv ntsug sab nraum lub cable core;
③ Cov ntaub thaiv hlau sib xyaw ua ke: siv cov ntawv ci txhuas Mylar daim kab xev lossis cov ntawv ci tooj liab Mylar daim kab xev los qhwv ib ncig lossis ntsug qhwv cov xov hlau lossis cov tub ntxhais cable;
④ Kev tiv thaiv kom tiav: Kev siv tau ntau yam los ntawm ntau hom kev tiv thaiv. Piv txwv li, qhwv (1-4) cov xov hlau tooj liab nyias nyias tom qab qhwv nrog daim kab xev Mylar txhuas. Cov xov hlau tooj liab tuaj yeem ua rau muaj kev cuam tshuam ntawm kev tiv thaiv;
⑤ Kev tiv thaiv sib cais + kev tiv thaiv tag nrho: txhua khub hlau lossis pawg hlau yog tiv thaiv los ntawm daim kab xev txhuas Mylar lossis hlau tooj liab braided sib cais, thiab tom qab ntawd cov qauv tiv thaiv tag nrho yog ntxiv tom qab cabling;
⑥ Kev qhwv tiv thaiv: Siv cov hlau tooj liab nyias, daim kab xev tooj liab tiaj tiaj, thiab lwm yam los qhwv ib ncig ntawm cov hlau rwb thaiv tsev, cov hlau khub lossis cov hlau cable.
* Cov qauv thiab cov ntaub ntawv tiv thaiv hluav taws xob
Kev tiv thaiv semi-conductive: Rau cov xov hluav taws xob ntawm 6kV thiab siab dua, ib txheej nyias nyias semi-conductive tiv thaiv raug txuas rau ntawm qhov chaw ntawm tus neeg xyuas hluav taws xob thiab qhov chaw rwb thaiv tsev. Txheej tiv thaiv tus neeg xyuas hluav taws xob yog ib txheej extruded semi-conductive. Kev tiv thaiv tus neeg xyuas hluav taws xob nrog qhov seem ntawm 500mm² thiab siab dua feem ntau yog tsim los ntawm daim kab xev semi-conductive thiab txheej extruded semi-conductive. Txheej tiv thaiv rwb thaiv tsev yog cov qauv extruded;
Kev qhwv hlau tooj liab: Cov hlau tooj liab puag ncig feem ntau yog siv rau kev qhwv ua ke, thiab txheej sab nraud yog qhwv rov qab thiab khi nrog daim kab xev tooj liab lossis hlau tooj liab. Hom qauv no feem ntau yog siv rau hauv cov cables nrog cov hluav taws xob luv luv loj, xws li qee cov cables loj 35kV. ib lub xov tooj fais fab;
Cov ntaub qhwv tooj liab: qhwv nrog cov ntaub qhwv tooj liab mos;
④ Cov ntaub thaiv txhuas corrugated: Nws siv cov extrusion kub lossis daim kab xev txhuas longitudinal qhwv, vuam, embossing, thiab lwm yam. Hom kev tiv thaiv no kuj muaj kev thaiv dej zoo heev, thiab feem ntau yog siv rau cov xov hluav taws xob siab thiab ultra-high-voltage.
4. Lub hnab looj tes
Lub luag haujlwm ntawm lub sheath yog los tiv thaiv lub cable, thiab lub hauv paus yog los tiv thaiv cov rwb thaiv tsev. Vim yog qhov chaw siv hloov pauv tas li, cov xwm txheej siv thiab cov neeg siv xav tau. Yog li ntawd, cov hom, cov qauv thiab cov 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 huab cua sab nraud, qee lub zog kho tshuab, thiab ib txheej tiv thaiv dav dav uas xav tau kev tiv thaiv kev sib khi dav dav (xws li tiv thaiv kev nkag ntawm cov pa dej thiab cov pa phem); Yog tias muaj lub zog sab nraud loj lossis dais qhov hnyav ntawm lub cable, yuav tsum muaj cov qauv txheej tiv thaiv ntawm cov hlau armor txheej; qhov thib peb yog cov qauv txheej tiv thaiv nrog cov kev cai tshwj xeeb.
Yog li ntawd, cov qauv sheath ntawm cov hlau thiab cable feem ntau muab faib ua ob qho tseem ceeb: sheath (lub tes tsho) thiab lub sheath sab nraud. Cov qauv ntawm lub sheath sab hauv yog qhov yooj yim, thaum lub sheath sab nraud suav nrog cov hlau armor txheej thiab nws cov txheej sab hauv (kom tiv thaiv cov hlau armor los ntawm kev puas tsuaj rau cov hlau sheath sab hauv), thiab lub sheath sab nraud uas yog los tiv thaiv cov hlau armor txheej, thiab lwm yam. Rau ntau yam kev xav tau tshwj xeeb xws li hluav taws kub retardant, hluav taws tsis kam, tiv thaiv kab (termite), tiv thaiv tsiaj (nas tom, noog peck), thiab lwm yam, feem ntau ntawm lawv tau daws los ntawm kev ntxiv ntau yam tshuaj rau lub sheath sab nraud; ob peb yuav tsum ntxiv cov khoom tsim nyog hauv cov qauv sheath sab nraud.
Cov ntaub ntawv siv feem ntau yog:
Polyvinyl chloride (PVC), polyethylene (PE), polyperfluoroethylene propylene (FEP), tsis muaj pa luam yeeb halogen tsawg, nplaim taws retardant polyolefin (LSZH/HFFR), thermoplastic elastomer (TPE)
