Kuyilo lwesakhiwo esitshaukumelana nomliloiintambo,polyethylene cross-linked (XLPE) insulatediintambo zisetyenziswa kakhulu. Babonisa ukusebenza kakuhle kombane, iipropathi zoomatshini, kunye nokuqina kokusingqongileyo. Ephawulwa ngamaqondo obushushu aphezulu okusebenza, amandla amakhulu othumelo, ukubeka okungenamda, kunye nofakelo olufanelekileyo kunye nokugcinwa, zimele ulwalathiso lophuhliso lweentambo ezintsha.
1. Uyilo lweCable Conductor
Ulwakhiwo lwe-Conductor kunye neempawu: Isakhiwo somqhubi samkela uhlobo lwesibini lwe-fan-shape lwesakhiwo somqhubi odibeneyo, usebenzisa (1 + 6 + 12 + 18 + 24) ulwakhiwo oluhlala rhoqo. Kwi-stranding eqhelekileyo, i-central layer iqulethe ucingo olunye, uluhlu lwesibini luneentambo ezithandathu, kwaye iileyile ezisondeleyo ezilandelayo zihluke ngeengcingo ezintandathu. Umaleko ongaphandle uxinene kwicala lasekhohlo, ngelixa ezinye iileya ezimeleneyo zixinene kwicala elichaseneyo. Iingcingo ziyisetyhula kunye nobubanzi obulinganayo, ziqinisekisa ukuzinza kwesi sakhiwo se-stranding. Ulwakhiwo olubambeneyo: Ngokudibana, umphezulu we-conductor uba mpuluswa, uthintela ukuxinana kwamasimi ombane. Kwangaxeshanye, ikhusela izixhobo ze-semi-conductive ekungeneni kwi-core wire ngexesha lokufakelwa kwe-extrusion, ukuthintela ngokufanelekileyo ukungena komswakama kunye nokuqinisekisa iqondo elithile lokuguquguquka. Iikondaktari ezixineneyo zinokuguquguquka okuhle, ukuthembeka, kunye namandla aphezulu.
2. I-Cable Insulation LayerYila
Indima yomaleko wokugquma kukuqinisekisa ukusebenza kombane wentambo kunye nokuthintela ukuhamba komsinga ecaleni komqhubi ukuvuza ngaphandle. Isakhiwo se-extrusion siqeshwe, ngeIzinto ze-XLPEekhethiweyo yokugquma. I-XLPE ibonelela ngentsebenzo egqwesileyo xa kuthelekiswa nepolyethylene, eneempawu ezigqwesileyo zokugquma umbane, eziphawulwa zii-dielectric constants ezincinci (ε) kunye ne-dielectric loss loss tangent (tgδ). Yeyona imathiriyeli yokugquma isantya esiphezulu. I-coefficient yokumelana nomthamo wayo kunye namandla entsimi okuqhekeka ahlala engatshintshi nasemva kweentsuku ezisixhenxe zokuntywiliselwa emanzini. Ngenxa yoko, isetyenziswa ngokubanzi kwi-cable insulation. Nangona kunjalo, inendawo esezantsi yokunyibilika. Xa zisetyenziswe kwiintambo, iimpazamo ezigqithisiweyo okanye ezimfutshane zingabangela ukunyuka kweqondo lokushisa, okukhokelela ekuthobeni kunye nokuguqulwa kwe-polyethylene, okubangelwa umonakalo we-insulation. Ukugcina iingenelo ze-polyethylene, idlula i-cross-linking, iphucula ukuchasana nobushushu kunye nokuchasana nokuxhatshazwa koxinzelelo lwendalo, okwenza izinto eziphathekayo ze-polyethylene zibe yinto efanelekileyo yokugquma.
3. UYilo lweCable Stranding kunye nokuSonga
Injongo ye-cable stranding kunye ne-wraping kukukhusela i-insulation, ukuqinisekisa i-core cable core, kunye nokuthintela ukugquma okukhululekile kunye nokuzaliswa, ukuqinisekisa ukujikeleza kwengundoqo. Iibhanti yokusongela idangatyeinikeza iimpawu ezithile zokunqanda amadangatye.
Izixhobo zeCable Stranding kunye nokuSonga: Isixhobo sokusonga sinqandeke kakhulu kwidangatye.ilaphu elingalukwangaibhanti, elinamandla okuqina kunye nesalathisi somlilo we-flame retardancy engekho ngaphantsi kwe-55% ye-oxygen index. Izinto zokuzalisa zisebenzisa iintambo zephepha ezingenamlilo (iintambo zamaminerali), ezithambileyo, kunye nesalathisi se-oksijini esingekho ngaphantsi kwe-30%. Iimfuno ze-cable stranding kunye nokusonga zibandakanya ukukhetha ububanzi bebhendi yokusonga ngokusekelwe kwidayamitha engundoqo kunye ne-angle yebhendi, kunye nokugqithwa okanye isithuba sokusonga. Isalathiso sokusonga sisekhohlo. Iibhanti ezinqanda amadangatya aphezulu ziyafuneka kumabhanti agange amadangatye. Ukumelana nobushushu bezinto zokuzalisa kufuneka kuhambelane nobushushu bokusebenza kwentambo, kwaye ukubunjwa kwayo akufanele kunxibelelane kakubiI-insulation sheath material.Kufuneka isuswe ngaphandle kokonakalisa i-insulation core.
