Intambo ekhuselweyo, njengoko igama libonisa, yintambo ene-anti-external electromagnetic interference capabilities eyenziwe ngohlobo lwentambo yothumelo enomaleko okhuselayo. Okubizwa ngokuba "ukukhusela" kwisakhiwo sekhebula kwakhona ngumlinganiselo wokuphucula ukuhanjiswa kweendawo zombane. I-conductor ye-cable iqulethwe yimicu emininzi yocingo, elula ukwenza i-gap yomoya phakathi kwayo kunye ne-insulation layer, kwaye i-conductor surface ayilulanga, eya kubangela ukuxinwa kwentsimi yombane.
1.Intambo ekhuselayo
(1). Yongeza umaleko okhuselayo we-semi-conductive material kumphezulu we-conductor, ohambelana ne-conductor ekhuselekileyo kunye nokudibanisa kakuhle kunye ne-insulation layer, ukwenzela ukuba ugweme ukukhutshwa okuyingxenye phakathi kwe-conductor kunye ne-insulation layer. Lo maleko wokhuselo ukwabizwa ngokuba ngumaleko okhuselayo wangaphakathi. Kusenokubakho izikhewu kuqhagamshelwano phakathi komphezulu wokugquma kunye ne-sheath, kwaye xa intambo igobile, i-oil-paper cable insulation surface kulula ukubangela iintanda, ezi zinto zibangela ukukhutshwa kwenxalenye.
(2). Yongeza umaleko okhuselayo we-semi-conductive material kumphezulu we-insulation layer, enoqhagamshelwano olufanelekileyo kunye ne-insulation layer kunye namandla alinganayo kunye ne-sheath yesinyithi, ukwenzela ukuba ugweme ukukhutshwa okuyingxenye phakathi komgangatho we-insulation kunye ne-sheath.
Ukuze kuqhutywe ngokulinganayo undoqo kunye nokugquma indawo yombane, i-6kV kunye neentambo zamandla ombane ophakathi kunye nophezulu ngokubanzi zinomaleko wekhaka le-conductor kunye ne-insulating shield layer, kwaye ezinye iintambo ezine-voltage ephantsi azinalo umaleko wekhaka. Kukho iindidi ezimbini zeeleya ezikhuselayo: i-semi-conductive shielding kunye nentsimbi yokukhusela.
2. Intambo ekhuselekileyo
Uluhlu olukhuselayo lwale ntambo luboshwe kakhulu kwinethiwekhi yeentambo zetsimbi okanye ifilimu yesinyithi, kwaye kukho iindlela ezahlukeneyo zokukhusela enye kunye nokukhusela okuninzi. Ikhaka elinye libhekisa kumnatha wekhaka elinye okanye ifilimu yekhaka, enokuthi isonge intambo enye okanye ngaphezulu. Imowudi ye-multi-shielding yi-multi-shielding networks networks, kwaye ifilimu yokukhusela ikwintambo enye. Ezinye zisetyenziselwa ukwahlula ukuphazamiseka kwe-electromagnetic phakathi kweengcingo, kwaye ezinye zizikhuselo eziphindwe kabini ezisetyenziselwa ukomeleza umphumo wokukhusela. Indlela yokukhusela kukumisa umaleko okhuselayo ukwahlula amandla ombane ophazamiseko owenziweyo wocingo lwangaphandle.
(1).Ikhaka le-semi-conductive
Umaleko okhuselayo we-semi-conductive udla ngokucwangciswa kumphezulu ongaphandle we-coondutive wire core kunye nomphandle wangaphandle we-insulation layer, ngokulandelelana ubizwa ngokuba yi-semi-conductive shielding layer kunye ne-external semi-conductive shielding layer. I-semi-conductive shielding layer iqulunqwe yi-semi-conductive material ene-resistiveivity ephantsi kakhulu kunye nobukhulu obuncinci. Uluhlu lwangaphakathi lwe-semi-conductive shielding layer yenzelwe ukuba ifanise intsimi yombane kwindawo yangaphandle ye-conductor core kwaye igweme ukukhutshwa kwenxalenye ye-conductor kunye ne-insulation ngenxa yomgangatho ongalinganiyo we-conductor kunye ne-gap yomoya ebangelwa yi-core stranded. Isikhuselo sangaphandle se-semi-conductive sinxibelelana kakuhle nomgangatho ongaphandle womgangatho wokugquma, kwaye silingana kunye neshethi yesinyithi ukuphepha ukukhutshwa ngokuyinxenye kunye ne-sheath yesinyithi ngenxa yeziphene ezinje ngeentanda kwindawo yokugquma intambo.
(2). Ikhaka lentsimbi
Kwiintambo zamandla ombane ophakathi kunye naphantsi ngaphandle kweeshethi zetsimbi, ukongeza ekusekweni kwekhaka le-semi-conductive, kodwa ukongeza umaleko wekhaka lentsimbi. Umaleko wekhaka lesinyithi udla ngokusongwa ngawoitheyiphu yobheduokanye ucingo lobhedu, oludlala kakhulu indima yokukhusela intsimi yombane.
Ngenxa yokuba i-current ngentambo yamandla inkulu kakhulu, i-magnetic field iya kuveliswa ngokujikeleza okwangoku, ukuze ingachaphazeli amanye amacandelo, ngoko ke umaleko okhuselayo unokukhusela le ntsimi ye-electromagnetic kwintambo. Ukongezelela, i-cable shielding layer inokudlala indima ethile ekukhuseleni umhlaba. Ukuba i-core cable yonakalisiwe, umsinga ovuzayo unokuhamba kunye ne-shielding laminar flow, njenge-networking networking, ukudlala indima ekukhuseleni ukhuseleko. Ingabonwa ukuba indima ye-cable shield layer isenkulu kakhulu.
