Isakhiwo esiyisisekelo socingo nentambo sifaka umqhubi wesifundo, ukufakwa, ukuvikelwa, sheath nezinye izingxenye.
1. Isiqhudweni
Umsebenzi: Ingxenye yengxenye yocingo nekhebula edlulisa amandla kagesi (uzibuthe), imininingwane futhi ibona imisebenzi ethile yokuguqulwa kwamandla nge-electromagnetic.
Izinto ezibonakalayo: Kunabashukumisa abangabafundisi, njengethusi, i-aluminium, i-alloy yethusi, i-aluminium alloy; Abaqhubi bensimbi abanama-batale, njengethusi elinombala, ithusi lesiliva, ithusi elinamathele; I-Metal-Clad Corpors, enjenge-Copper-Clad Steel, i-Copper-Clad aluminium, i-aluminium clad yensimbi, njll.
2. Ukufakelwa
Umsebenzi: Isendlalelo sokufaka okufakwayo sigoqiwe umqhubi noma ungqimba owengeziwe womqhubi (njengetheyiphu ye-mica refrackorder), futhi umsebenzi wawo ukuhlukanisa umqhubi kusuka ku-voltage ehambisanayo futhi uvikele ukuvuza kwamanje.
Izinto ezisetshenziswa ngokujwayelekile zokufakwa kwe-extvinyl chloride (PVC), PVC), Polyethylene (Pe) Irabha (EPM / EPDM), njll.
3. Ukuvikela
Umsebenzi: Isendlalelo sokuvikela esisetshenziswe ocingweni nemikhiqizo ye-Cable empeleni inemibono emibili ehluke ngokuphelele.
Okokuqala, ukwakheka kwezintambo nezintambo ezidlulisela amagagasi we-electromagnetic aphezulu kakhulu (njengemvamisa yomsakazo, izintambo ze-elekthronikhi) noma amakhefu abuthakathaka (njengezintambo zesiginali) zibizwa ngokuthi ukuvikelwa kwe-electromagnetic. Inhloso ukuvimba ukuphazanyiswa kwamagagasi ama-electromagnetic angaphandle, noma ukuvimba amasiginali afudumele aphezulu kwintambo kusuka ekuphazamiseni umhlaba wangaphandle, futhi ukuvikela ukuphazanyiswa kwababili phakathi kwababili ngocingo.
Okwesibili, ukwakheka kwamakhabethe ama-voltage aphakathi nendawo afanayo ukulinganisa insimu kagesi kwi-Conductor Surce noma indawo evumayo ibizwa ngokuthi yinsimu kagesi. Ukukhuluma ngokuqinile, ukuvikelwa kwensimu kagesi akudingi umsebenzi we- "Shielting", kepha udlala indima ye-Homogenize. Isihlangu esimboza ikhebula sivame ukubekwa.
* Ukwakheka okuvikelekile kwe-electromagnetic
① Ukuvikelwa Kokuvinjelwe: Kakhulu sebenzisa ucingo lwethusi olungenalutho, i-Tin-Pred Copper Wire, Ucingo lwe-Aluminium-Magnesium Alloy, I-Tape Peppere Flather, njll.
② I-Teppear Shiepting: Sebenzisa itheyipu yethusi ethambile ukumboza noma ukugoqa ngaphandle komgogodla wekhebula;
③ Ukuvikelwa kwe-tepi ye-tepi yensimbi yensimbi ye-Metal
④ Ukuvikelwa Okuphelele: Isicelo esiphelele ngezindlela ezahlukahlukene zokuvikelwa.Isibonelo, ukugoqa (1-4) Izintambo zethusi ezimbalwa zibheke ngemuva kokugoqwa nge-aluminium foil mylar tape. Izintambo zethusi zingakhulisa umphumela wokutholwa kokuvikelwa;
⑤ Ukuvikelwa okuvikelekile + okuvikelekile okuphelele: I-wire pair ngayinye noma iqembu lezintambo livikelwe i-aluminium foil mylar noma ithuluzi lethusi elihlukaniswe ngokwahlukana, bese kufakwa isakhiwo sesikhathi esijwayelekile ngemuva kokubuthaka;
⑥ Shielping Shielding: Sebenzisa ucingo lwethusi oluncane, itheyiphu ye-Copper flat, njll. Ukusonga uzungeze umnyombo we-wire ofakiwe, i-wire pair noma ikhebula.
* Ukwakheka kwensimu yegesi kanye nezinto zokwakha
Ukuvikelwa okuqhutshwa yisikhathi: Ukuze uthole izintambo zamandla ze-6kv nangaphezulu, ungqimba lwe-Shielding oluncane olunamathele ku-Conductor Surce kanye ne-Insulating Parcer. Isendlalelo sokuvikelwa kwesifundo seConfuli yisendlalelo esenziwe nge-semi-esiqhutshwayo. Ukuvikelwa kwesikimu ngesigaba esisesigabeni se-500mm² nangaphezulu kuvame ukwakhiwa nge-tepi evuthayo kanye nesendlalelo esenziwe ngokungemthetho. Isendlalelo sokuvikela esivikelekile sesakhiwo esikhiqizwayo;
Ukugoqwa kocingo lwethusi: I-wire eyindilinga eyindilinga isetshenziselwa kakhulu ukugoqwa okuqondayo, futhi ungqimba lwangaphandle lulinyazwa kabusha futhi luboshwe ngethepisi noma ithusi lethusi. Lolu hlobo lwesakhiwo luvame ukusetshenziswa kumakhebuli anesizungu esikhulu sesekethe, njengezintambo zezinye izigaba ezingama-35kv. ikhebula lamandla angashadile;
Ukugoqa kwe-Copper: ukugoqa nge-tepipopopopuponse ethambile;
④ I-Aluminium Sheath ehlanganisiwe: Ikwamukela ukukhishwa okushisayo noma i-aluminium tape longitudinal ukugoqa, ukufakwa, okuhlanganisiwe, njll. Lolu hlobo lokuvikelwa kwamanzi lube nokuvikelwa kwamanzi okuphezulu kanye ne-Ultra-high-voltage yamakhekhe.
4. Sheath
Umsebenzi we-sheath ukuvikela ikhebula, futhi umnyombo ukuvikela ukufakwa. Ngenxa yemvelo yokusetshenziswa okuguqukayo njalo, izimo zokusetshenziswa kanye nezidingo zomsebenzisi. Ngakho-ke, izinhlobo, amafomu ezakhiwo kanye nezidingo zokusebenza kwesakhiwo se-sheahing nazo ziyahlukahluka, ezingafingqiswa zibe izigaba ezintathu:
Eyodwa ukuvikela izimo zesimo sezulu zangaphandle, amandla okwenziwa ngezikhathi ezithile, kanye nongqimba olujwayelekile lokuzivikela oludinga ukuvikelwa kokubekwa uphawu okujwayelekile (njengokuvimbela ukungenela komugqa wamanzi namagesi ayingozi); Uma kukhona amandla amakhulu angaphandle okusebenza noma athwale isisindo sentambo, kufanele kube nokwakheka okubusayo kwensimbi yensimbi yensimbi; Okwesithathu yisakhiwo esivikelayo esinezidingo ezikhethekile.
Ngakho-ke, isakhiwo se-sheath socingo nentambo ngokuvamile sihlukaniswe izingxenye ezimbili ezinkulu: Sheath (Sleeve) kanye ne-sheath yangaphandle. Ukwakheka kwe-Sheath yangaphakathi kulula kakhulu, kuyilapho i-sheath yangaphandle ifaka ungqimba lwezembatho zensimbi kanye nongqimba lwangaphakathi lwe-lining (ukuvikela ungqimba lwezembatho luzovikela ungqimba lwezembatho, njll. Okwezilwane (insadi yokulwa nezinambuzane, i-anti-animation), njll, iningi labo liyaxazululwa ngokungeza amakhemikhali ahlukahlukene emgodini wangaphandle; Abambalwa kufanele bangeze izakhi ezidingekayo ekwakhiweni kwe-sheath yangaphandle ..
Izinto ezisetshenziswayo ezivame ukusetshenziswa yilezi:
Polyvinyl Chloride (PVC), Polyethylene (PE), Polyperfluoroethylene Porylene (Fep), Intuthu ephansi I-Halogen Mahhala Flame Retardant Polyolefashini (I-LSZH / HHFFR), Thermoplastic elastomer (TPE)
