Isakhiwo esisisiseko socingo kunye nentambo ibandakanya i-conductor, i-insulation, ukukhusela, i-sheath kunye nezinye iindawo.
1. Umqhubi
Umsebenzi: I-Conductor yinxalenye yocingo kunye nentambo ehambisa amandla ombane (magnetic), ulwazi kunye nokuqonda imisebenzi ethile yokuguqulwa kwamandla ombane.
Izinto eziphathekayo: Kukho ii-conductors ezingafakwanga, ezifana nobhedu, i-aluminium, i-alloy yobhedu, i-alloy aluminium; ii-conductor ezenziwe ngesinyithi, ezifana nobhedu olufakwe kwi-tinned, i-copper-plated copper, i-nickel-plated copper; abaqhubi bentsimbi, ezifana nentsimbi yobhedu, i-aluminium ene-copper-clad, i-aluminium enentsimbi, njl.
2. I-Insulation
Umsebenzi: I-insulating layer ihlanganiswe kwi-conductor okanye i-layer eyongezelelweyo ye-conductor (efana ne-refractory mica tape), kwaye umsebenzi wayo kukuhlukanisa umqhubi ekuthwaleni i-voltage ehambelanayo kunye nokuthintela ukuvuza kwangoku.
Izinto eziqhelekileyo ezisetyenziselwa ukufakwa kwe-extruded i-polyvinyl chloride (PVC), i-polyethylene (PE), i-polyethylene edibeneyo (i-XLPE), i-halogen-free-flame retardant polyolefin (LSZH / HFFR), i-fluoroplastics, i-thermoplastic elasticity (TPE), irubha ye-silicone ye-rubber (EPMpyDM), i-epiklea ye-silicone, njl
3. Ukukhusela
Umsebenzi: Umaleko okhuselayo osetyenziswa kwiimveliso zocingo kunye nentambo eneneni unemiqondo emibini eyahlukileyo ngokupheleleyo.
Okokuqala, ulwakhiwo lweengcingo kunye neentambo ezisasaza amaza e-electromagnetic (afana nefrikhwensi yerediyo, iintambo zombane) okanye imisinga ebuthathaka (enjengeentambo zomqondiso) ibizwa ngokuba yi-electromagnetic shielding. Injongo kukuthintela ukuphazamiseka kwamaza e-electromagnetic yangaphandle, okanye ukuthintela izibonakaliso ze-high-frequency kwi-cable ukuba ziphazamise ihlabathi langaphandle, kunye nokuthintela ukuphazamisana phakathi kwee-wire pairs.
Okwesibini, ulwakhiwo lweentambo zamandla ombane ophakathi kunye nophezulu ukulinganisa intsimi yombane kumphezulu we-conductor okanye indawo yokukhusela ibizwa ngokuba yi-electric field shielding. Ukuthetha ngokuthe ngqo, ukukhusela intsimi yombane ayifuni umsebenzi "wokukhusela", kodwa idlala indima ye-homogenizing intsimi yombane. Ikhaka elijikeleza ikhebula lihlala liphantsi.
* Ubume be-electromagnetic shielding kunye nemathiriyeli
① Ukhuselo olulukiweyo: ubukhulu becala sebenzisa ucingo lobhedu olungenanto, ucingo olufakwe kwinkcenkceshe lobhedu, ucingo lobhedu olufakwe kwisilivere, i-aluminium-magnesium alloy wire, itheyiphu eflethi yobhedu, itheyiphu ecwecwe ngesilivere, njl.
② Ukhuselo lweteyiphu yobhedu: sebenzisa itheyiphu yobhedu ethambileyo ukugquma okanye ukusonga ngokuthe nkqo ngaphandle kombindi wentambo;
③ Ukukhusela itheyiphu ehlanganisiweyo yesinyithi: sebenzisa ifoyile yealuminiyam iteyiphu yeMylar okanye ifoyile yobhedu iMylar tape ukusonga okanye ngokuthe nkqo ukusonga iperi yocingo okanye umbindi wentambo;
④ Ukhuselo olubanzi: Ukusetyenziswa okubanzi ngeendlela ezahlukeneyo zokukhusela.Ngokomzekelo, bopha (1-4) iingcingo ezibhityileyo zobhedu ngokuthe nkqo emva kokusonga ngefoyile ye-aluminium ye-Mylar tape. Iingcingo zobhedu zinokunyusa isiphumo sokuqhuba isikhuselo;
⑤ Ukukhusela okwahlukileyo + ukukhuselwa ngokubanzi: isibini ngasinye socingo okanye iqela leecingo likhuselwe ngefoyile ye-aluminium i-Mylar tape okanye ucingo lobhedu oluphothiweyo ngokwahlukileyo, kwaye emva koko isakhiwo sokukhusela sisongezwa emva kwekhebula;
⑥ Ukusonga isikhuselo: Sebenzisa ucingo olubhityileyo lobhedu, iteyiphu ecwecwe yobhedu, njl.
* Isakhiwo sokukhusela intsimi yombane kunye nezixhobo
I-semi-conductive shielding: Kwiintambo zamandla ze-6kV nangaphezulu, umaleko obhityileyo we-semi-conductive okhuselayo uncanyathiselwe kumphezulu we-conductor kunye ne-insulating surface. Umaleko okhuselayo we-conductor ngumaleko ogqithisiweyo we-semi-conductive. I-conductor ekhuselayo enecandelo elinqamlezileyo le-500mm² nangaphezulu ngokuqhelekileyo yenziwe ngeteyiphu ene-semi-conductive kunye nomaleko okhutshiweyo wesemi-conductive. I-insulating shielding layer is extruded structure;
Ukusonga ucingo lweCopper: Ucingo lobhedu olungqukuva lusetyenziswa ikakhulu ukusonga i-co-directional, kwaye umaleko wangaphandle uhlaselwe umva kwaye ubotshwe ngeteyiphu yobhedu okanye ucingo lobhedu. Olu hlobo lolwakhiwo ludla ngokusetyenziswa kwiintambo ezinombane omkhulu wesekethe emfutshane, njengeentambo zecandelo elikhulu le-35kV. intambo yamandla engundoqo enye;
Ukuvalwa kwetape yobhedu: ukugubungela ngeteyiphu ethambileyo yobhedu;
④ I-alluminiyamu sheath ekhutshiweyo: Yamkela i-extrusion eshushu okanye i-aluminium tape yokuvala i-longitudinal, i-welding, i-embossing, njl.
4. Isingxobo
Umsebenzi we-sheath kukukhusela ikhebula, kwaye ingundoqo kukukhusela i-insulation. Ngenxa yemeko-bume yokusetyenziswa ehlala itshintsha, iimeko zokusetyenziswa kunye neemfuno zabasebenzisi. Ke ngoko, iintlobo, iifom zolwakhiwo kunye neemfuno zentsebenzo yesakhiwo se-sheathing nazo ziyahlukahlukana, ezinokushwankathelwa zibe ziindidi ezintathu:
Enye kukukhusela iimeko zemozulu zangaphandle, amandla omatshini ngamanye amaxesha, kunye nomgangatho wokukhusela jikelele ofuna ukukhuselwa kokutywinwa ngokubanzi (njengokuthintela ukungena komphunga wamanzi kunye neegesi eziyingozi); Ukuba kukho i-mechanical force enkulu yangaphandle okanye ithwala ubunzima bekhebula, kufuneka kubekho ulwakhiwo olukhuselayo loluhlu lwezixhobo zetsimbi; eyesithathu yisakhiwo somaleko okhuselayo kunye neemfuno ezizodwa.
Ke ngoko, ulwakhiwo lwe-sheath yocingo kunye nentambo ngokubanzi lwahlulwe lube ngamacandelo amabini amakhulu: i-sheath (i-sleeve) kunye ne-sheath yangaphandle. Isakhiwo esingxotyeni sangaphakathi ilula ngokwentelekiso, lo gama engxoweni yangaphandle ibandakanya umaleko isikrweqe sentsimbi kunye umaleko wangaphakathi lining (ukuthintela umaleko isikrweqe ekonakalisa umaleko esingxotyeni sangaphakathi), kunye nengxondorha yangaphandle leyo ukukhusela isikrweqe umaleko, njl Kuba iintlobo ngeentlobo zeemfuno ezizodwa ezifana idangatye retardant, ukumelana nomlilo, anti-insect (termite), anti-isilwanyana, ukusombulula intaka, anti-izilwanyana ezininzi, njl njl. ukongeza iikhemikhali ezahlukeneyo kwi-sheath yangaphandle; abambalwa kufuneka bongeze amacandelo ayimfuneko kwisakhiwo seshefu yangaphandle.
Izinto ezisetyenziswa ngokuqhelekileyo zezi:
I-Polyvinyl chloride (PVC), i-polyethylene (PE), i-polyperfluoroethylene propylene (FEP), i-halogen ephantsi yomsi we-flame retardant polyolefin (LSZH/HFFR), i-thermoplastic elastomer (TPE)
