Mukugadzira waya netambo, zvinhu zvinofambisa magetsi zvinonyanya kusanganisira sirivha, mhangura, nearuminiyamu. Sirivha ndiyo inonyanya kupinza magetsi, asi nekuda kwekudhura kwayo, inowanzo shandiswa mutambo dzemasaini dzinoshandisa mafrequency akawanda, tambo dzezvishandiso zvine hungwaru, uye tambo dzeaudio dzemhando yepamusoro. Mhangura ine hunyanzi hwemagetsi hunotevera sirivha uye inopa kugona kugadzikiswa zvakanaka, hunhu hwemakanika, uye kuramba ngura, zvichiita kuti ishandiswe zvakanyanya mutambo dzemagetsi, waya dzekuvaka, tambo dzekudzora, uye tambo dzekutaurirana. Aruminiyamu ine hunyanzi hwemagetsi hunosvika 60% (inenge 61% IACS) ukuwo iine chikamu chimwe muzvitatu chehunyanzi hwemhangura uye mutengo wakaderera, zvichiita kuti ishandiswe zvakanyanya mutambo dzinodzivirira mhepo, tambo dzemagetsi, uye tambo dzemagetsi dzakakura.
Kushanda kwemuchina wekufambisa hakungotsamiri pasimbi chete asiwo pakushanda kwemakemikari anodziisa, makemikari anovhara jira, uye masisitimu ane chekuita nazvo. Semuenzaniso, tichitarisa mhangura isina oxygen yakakwana, kusakwana kwekushanda kwechinhu kunogona kukonzera matambudziko ekugadzikana kwenzvimbo panguva yekushanda kwenguva refu, izvo zvinogona kukanganisa mashandiro emagetsi uye kuvimbika. Polyvinyl Chloride (PVC),Polyethylene Yakabatana Nemuchinjikwa (XLPE), uye Polypropylene (PP) insulation compounds imwe neimwe ine hunhu hwakasiyana maererano nekupisa, mashandiro emagetsi, uye kugadzikana kwemakemikari. Pakati padzo, XLPE nePP zvinowanzo kukodzera zviri nani kune zvishandiso zvinoda tembiricha yakakwira kana kushanda kwemagetsi kwakawedzerwa. Nokudaro, kuenderana kweconductor-insulation chinhu chakakosha pakugadzira tambo.
Munguva yekudhirowa waya, maconductor emhangura anowedzera kushushikana kwemukati, izvo zvinogona kukanganisa kufambiswa kwemagetsi. Kuburikidza nekunamira, kufambiswa kwemagetsi kunogona kuvandudzwa ukuwo kuchivandudza kuchinjika. Zvisinei, maconductor emhangura akapfava ane simba shoma remuchina. Nekuda kweizvozvo, kushushikana kweconductor, tembiricha yekubvisa mhepo, uye mamiriro ekutonhorera zvinofanirwa kudzorwa nemazvo panguva yekunamira kwemhepo kuti ive nechokwadi chekugadzikana kweconductor uye kufanana kwechikamu chekudzivirira. Izvi zvinoratidza kukosha kwekubatana pakati pekugadzirisa conductor uye maitiro ekubvisa mhepo.
Mukutumira masaini emagetsi ane mafrequency akakwira, ganda rinoita kuti magetsi arambe akananga pamusoro pemutyairi, zvichiita kuti hunhu hwemutyairi wemagetsi pamusoro huve hwakakosha zvikuru. Mune mamwe mashandisirwo anonyanya kukosha, maconductor eCopper-Clad Aluminium (CCA) anoshandiswa kuenzanisa mutengo nehuremu, nepo maconductor eSilver-Coated Copper (SCC) kana esirivha-plated copper anoshandiswa zvakanyanya mukushandisa kwepamusoro-soro uye kuvimbika kwepamusoro. Panguva imwecheteyo, zvinhu zvinodzivirira zvine dielectric yakaderera uye dielectric yakaderera kurasikirwa - senge Foam Polyethylene (Foam PE), Foam Polypropylene (Foam PP), uye high-purity XLPE compounds - zvinogona kubatsira kuderedza kuderera kwechiratidzo uye kuvandudza mashandiro ekutumira masaini emagetsi ane mafrequency akakwira.
Mashandisirwo akasiyana-siyana anoda zvinhu zvakasiyana-siyana zvekufambisa. Tambo dzekutumira zviratidzo dzechitima dzinowanzo tungamira maconductor emhangura kuti ive nechokwadi chekuti michina yakavimbika uye kuti masignal agare zvakanaka. Mitsetse yekufambisa mudenga inoshandisa maconductor ealuminium, anowanzo sanganiswa nePVC kana nhema Polyethylene (PE) sheathing inodzivirira mamiriro ekunze kuti igare kwenguva refu. Tambo dzemugungwa nedzekunze kwegungwa dzinowanzo tungamira macompounds eLow Smoke Zero Halogen (LSZH) sheathing kuti isangane nezvinodiwa zvekuchengetedza moto zvine utsi hushoma, halogen-free, uye low chepfu. Mumaharnesses emagetsi matsva (NEV), maconductor ealuminium anoda macompounds ekudzivirira anoenderana neXLPE, macompounds ekupisa anodzivirira kupisa, uye mhinduro dzekubatanidza terminal dzakagadzirwa kuti ive nechokwadi chekuti kubatana kwakavimbika kwenguva refu.
Muchidimbu, kusarudzwa kwemuchina wekufambisa hakungosanganisiri chete kufambiswa kwemhepo, simba remuchina, huremu, uye mutengo, asiwo dhizaini yakarongeka yemakemikari ekudzivirira kupisa, makemikari ekudzivirira kupisa, nezvimwe zvinhu zvine chekuita netambo. Zvinhu zvakaita semakemikari ekudzivirira kupisa eXLPE, makemikari ekudzivirira kupisa ePVC,LSZH makemikari, Foam PE, uye Thermoplastic Elastomers (TPE) zvinokanganisa zvakananga mashandiro emagetsi, kuramba kupisa, uye hupenyu hwebasa remaconductor. Kuenderana kwakakodzera pakati pemaconductor nezvinhu zvetambo kwakakosha kuti tambo dzive dzakavimbika uye dzinoshanda zvakanaka.
