Pakuyika ndi kugwiritsira ntchito chingwecho, chimawonongeka ndi kupanikizika kwa makina, kapena chingwecho chimagwiritsidwa ntchito kwa nthawi yaitali m'malo otsekemera ndi madzi, zomwe zidzachititsa kuti madzi akunja alowe pang'onopang'ono mu chingwe. Pansi pa ntchito yamagetsi, kuthekera kopanga mtengo wamadzi pazitsulo zotchingira chingwe kudzawonjezeka. Mtengo wamadzi wopangidwa ndi electrolysis udzaphwanya kutsekereza, kuchepetsa magwiridwe antchito onse a chingwe, ndikukhudza moyo wautumiki wa chingwe. Choncho, kugwiritsa ntchito zingwe zosalowa madzi n’kofunika kwambiri.
Chingwe chosalowa madzi chimaganiziranso kutha kwa madzi motsatira njira ya kondakitala wa chingwe komanso njira yozungulira ya chingwe kudzera pachimake cha chingwe. Chifukwa chake, mawonekedwe otchinga madzi otalikirapo komanso otalikirapo a chingwe angagwiritsidwe ntchito.
1.Chingwe chopanda madzi
Cholinga chachikulu cha ma radial waterproofing ndi kuteteza madzi ozungulira kunja kwa chingwe pakugwiritsa ntchito. Kapangidwe kamadzi kamakhala ndi njira zotsatirazi.
1.1 Polyethylene sheath yopanda madzi
Polyethylene sheath yopanda madzi imagwira ntchito pazofunikira zonse zosagwirizana ndi madzi. Kwa zingwe zomizidwa m'madzi kwa nthawi yayitali, magwiridwe antchito osalowa madzi a zingwe zamagetsi za polyethylene sheathed madzi ayenera kuwongolera.
1.2 Metal sheath yopanda madzi
Ma radial osalowa madzi a zingwe zotsika mphamvu zokhala ndi voteji ya 0.6kV/1kV ndi kupitilira apo, nthawi zambiri amazindikira kudzera pagawo lakunja loteteza komanso kukulunga kwamkati kwa lamba wopangidwa ndi mbali ziwiri wa aluminiyamu-pulasitiki. Zingwe zamagetsi zapakatikati zokhala ndi voteji 3.6kV/6kV ndi pamwambapa ndizopanda madzi zowongoka pansi polumikizana ndi lamba wa aluminiyamu-pulasitiki komanso payipi yapakati-conductive resistance. Zingwe zamagetsi zokwera kwambiri zokhala ndi ma voliyumu okwera kwambiri zimatha kukhala zopanda madzi okhala ndi zitsulo zokhala ndi zitsulo monga ma sheath kapena malata a aluminiyamu.
Comprehensive sheath madzi ndi makamaka ntchito chingwe ngalande, mwachindunji m'manda mobisa madzi ndi malo ena.
2. Chingwe chopanda madzi
Kukana kwamadzi kwautali kumatha kuganiziridwa kuti kumapangitsa kuti chingwe chowongolera ndi kusungunula chikhale ndi mphamvu yokana madzi. Pamene chingwe chakunja choteteza chingwe chawonongeka chifukwa cha mphamvu zakunja, chinyezi chozungulira kapena chinyezi chidzalowa molunjika pamodzi ndi woyendetsa chingwe ndi njira yotetezera. Pofuna kupewa chinyezi kapena kuwonongeka kwa chinyezi pa chingwe, tingagwiritse ntchito njira zotsatirazi kuti titeteze chingwe.
(1)Tepi yotchinga madzi
Malo okulitsa osamva madzi amawonjezedwa pakati pa waya wotsekeredwa ndi chingwe cha aluminiyamu-pulasitiki. Tepi yotchinga madzi imakutidwa pakatikati pa waya wotsekeredwa kapena pachimake cha chingwe, ndipo kukulunga ndi kuphimba ndi 25%. The Water blocking tepi imakula ikakumana ndi madzi, zomwe zimawonjezera kulimba pakati pa tepi yotsekera Madzi ndi sheath ya chingwe, kuti akwaniritse kutsekereza madzi.
(2)Semi-conductive madzi kutsekereza tepi
Semi-conductive madzi kutsekereza tepi chimagwiritsidwa ntchito sing'anga voteji chingwe, ndi kukulunga Semi-conductive madzi kutsekereza tepi kuzungulira zitsulo kutchinga wosanjikiza, kukwaniritsa cholinga cha longitudinal madzi kukana chingwe. Ngakhale kutsekereza kwamadzi kwa chingwe kumakhala bwino, kutalika kwakunja kwa chingwe kumawonjezeka pambuyo poti chingwecho chikukulungidwa pa tepi yotchinga madzi.
(3)Kutsekereza madzi
Zida zodzaza madzi oletsa madzi nthawi zambiriulusi wotsekereza madzi(chingwe) ndi ufa wotsekereza madzi. Ufa wotsekereza madzi umagwiritsidwa ntchito kwambiri kutsekereza madzi pakati pa zopindika za conductor cores. Pamene madzi otsekera ufa ndi ovuta kugwirizanitsa ndi kondakitala monofilament, zomatira zabwino zamadzi zingagwiritsidwe ntchito kunja kwa conductor monofilament, ndipo ufa wotsekera madzi ukhoza kukulungidwa kunja kwa woyendetsa. Ulusi wotsekereza madzi (chingwe) nthawi zambiri umagwiritsidwa ntchito kudzaza mipata pakati pa zingwe zapakati-pakatikati pazingwe zitatu.
3 General kapangidwe ka chingwe madzi kukana
Malinga ndi malo osiyanasiyana ogwiritsira ntchito komanso zofunikira, mawonekedwe oletsa madzi a chingwe amaphatikiza mawonekedwe osalowerera madzi, kutalika (kuphatikiza ma radial) kukana madzi komanso mawonekedwe ozungulira madzi. Mapangidwe oletsa madzi a chingwe chapakati chapakati chapakati pa atatu amatengedwa monga chitsanzo.
3.1 Ma radial osalowa madzi a chingwe chapakati chapakati chamagetsi atatu
Kutsekereza madzi kwamagetsi kwa chingwe chapakati chapakati chamagetsi atatu nthawi zambiri kumatenga tepi yotchinga madzi ya Semi-conductive ndi tepi ya pulasitiki yokhala ndi mbali ziwiri ya aluminiyamu kuti ikwaniritse ntchito yokana madzi. Mapangidwe ake onse ndi: kondakitala, chotchinga chotchinga, chotchingira, chotchingira chotchinga, chotchinga chachitsulo (tepi yamkuwa kapena waya wamkuwa), kudzaza wamba, tepi yotchinga madzi yotsekera, pulasitiki yokhala ndi mbali ziwiri yokutidwa ndi aluminium tepi longitudinal, sheath yakunja. .
3.2 Atatu-pachimake sing'anga voteji chingwe longitudinal madzi kukana dongosolo
Chingwe chamagetsi chapakati chapakati pa atatu chimagwiritsanso ntchito tepi yotchinga madzi yotsekera komanso tepi ya aluminiyamu yokhala ndi mbali ziwiri kuti ikwaniritse ntchito yokana madzi. Kuphatikiza apo, chingwe chotchinga madzi chimagwiritsidwa ntchito kudzaza kusiyana pakati pa zingwe zitatu zazikuluzikulu. Kapangidwe kake kake ndi: kondakitala, chotchinga chotchinga, chotchingira, chotchinga chotchinga, tepi yotchinga madzi yotchinga, chitsulo chotchinga (tepi yamkuwa kapena waya wamkuwa), kudzaza zingwe zotsekereza madzi, tepi yotchinga madzi yotsekera, sheath yakunja.
3.3 Chingwe chapakati chapakati chamagetsi atatu chozungulira kuzungulira madzi
Chingwe chotchinga madzi chozungulira chimafuna kuti woyendetsayo akhalenso ndi mphamvu yoletsa madzi, ndikuphatikizana ndi zofunikira zotsekera madzi ozungulira komanso otalikirapo madzi, kuti akwaniritse kutsekereza madzi mozungulira. Kapangidwe kake kake ndi: kondakitala wotchinga madzi, chotchinga chotchinga, chotchingira, chotchinga chotchinga, tepi yotchinga madzi yotchinga, chitsulo chotchinga (tepi yamkuwa kapena waya wamkuwa), kudzaza zingwe zotsekereza madzi, tepi yotchinga madzi. , pulasitiki yokhala ndi mbali ziwiri yokutidwa ndi aluminiyamu tepi yotalikirapo, sheath yakunja.
Chingwe chotchinga madzi chapakati-patatu chikhoza kusinthidwa kukhala zingwe zitatu zotsekera madzi zotchingira madzi (zofanana ndi zingwe zitatu zapakati pamlengalenga). Ndiko kuti, chingwe chilichonse chimapangidwa molingana ndi chingwe chotchinga madzi, ndiyeno zingwe zitatu zosiyana zimapotozedwa kudzera pa chingwe kuti zilowe m'malo mwa chingwe chotchinga madzi. Mwa njira iyi, osati kusintha madzi kukana kwa chingwe, komanso kupereka mayiko kwa processing chingwe ndipo kenako unsembe ndi atagona.
4.Kusamala popanga zolumikizira chingwe chotsekereza madzi
(1) Sankhani zida zoyenera zolumikizirana molingana ndi mafotokozedwe ndi zitsanzo za chingwe kuti mutsimikizire mtundu wa chingwe cholumikizira.
(2) Osasankha masiku amvula popanga zingwe zotsekera madzi. Izi ndichifukwa choti madzi a chingwe angakhudze kwambiri moyo wautumiki wa chingwe, ndipo ngakhale ngozi zazifupi zidzachitika pazifukwa zazikulu.
(3) Musanapange zingwe zosagwirizana ndi madzi, werengani mosamala malangizo a wopanga.
(4) Mukakanikiza chitoliro chamkuwa chophatikizirapo, sichingakhale cholimba kwambiri, bola chikanikizidwa pamalopo. Nkhope ya mkuwa pambuyo pa crimping iyenera kuyikidwa mosabisa popanda burrs.
(5) Pamene ntchito blowtorch kupanga chingwe kutentha kuotcha olowa, kulabadira blowtorch kusuntha mmbuyo ndi mtsogolo, osati mbali imodzi nthawi zonse blowtorch.
(6) Kukula kwa chingwe chozizira chochepetsera chingwe chiyenera kuchitidwa motsatira ndondomeko yojambula, makamaka pochotsa chithandizo mu chitoliro chosungidwa, chiyenera kusamala.
(7) Ngati kuli kofunikira, chosindikizira chingagwiritsidwe ntchito pazigawo za chingwe kuti asindikize ndi kupititsa patsogolo mphamvu ya chingwe chopanda madzi.
