Mukugadzirwa kwemaitiro matsvaisingadziviriri mototambo,cross-yakabatana polyethylene (XLPE) insulatedtambo dzinoshandiswa zvakanyanya. Ivo vanoratidza kuita kwakanakisa kwemagetsi, zvivakwa zvemuchina, uye kusimba kwezvakatipoteredza. Inoratidzirwa nekupisa kwakanyanya kwekushanda, hukuru hwekutapurirana masimba, kuisa kusingabvumirwe, uye nyore kuisirwa nekugadzirisa, ivo vanomiririra kutungamira kwetambo nyowani.
1. Cable Conductor Design
Conductor Mamiriro uye Hunhu: Iyo conductor chimiro inotora fan-yakaumbwa yechipiri mhando yekombuta conductor chimiro, uchishandisa (1 + 6 + 12 + 18 + 24) yakajairwa chimiro. Mutambo wenguva dzose, mutsara wepakati une waya imwe, yechipiri ine waya nhanhatu, uye mitsara yakatarisana inosiyana netambo nhanhatu. Iyo yekunze-yekunze yakasungirirwa-kuruboshwe, nepo mamwe matinji ari pedyo akasungirirwa kune rimwe divi. Waya dzakaita denderedzwa uye dzakaenzana dhayamita, zvichiita kuti pave nekugadzikana mune iyi stranding chimiro. Compact dhizaini: Kuburikidza nekumisikidza, iyo conductor pamusoro inova yakatsetseka, ichidzivirira kusungirirwa kwemagetsi minda. Panguva imwe cheteyo, inodzivirira semi-conductive zvinhu kubva pakupinda waya core panguva ye extrusion insulation, zvinobudirira kudzivirira kupenya kwemvura uye kuve nechokwadi cheimwe nhanho yekushanduka. Stranded conductors vane yakanaka kuchinjika, kuvimbika, uye yakakwirira simba.
2. Cable Insulation LayerDesign
Basa reiyo insulation layer ndeye kuona kuti tambo inoshanda nemagetsi uye kudzivirira kuyerera kweazvino padivi pe conductor kubva pakubuda kunze. An extrusion chimiro chinoshandiswa, neXLPE zvinhuyakasarudzwa nokuda kwekudzivirira. XLPE inopa kuita kwepamusoro kana ichienzaniswa nepolyethylene, ine yakanakisa magetsi ekudzivirira zvivakwa, inoratidzwa nediki dielectric constants (ε) uye yakaderera dielectric kurasikirwa tangent (tgδ). Yakanakira yakakwirira-frequency insulation material. Huwandu hwayo hwekupikisa coefficient uye kuparara kwemunda simba kunoramba kusingachinjiki kunyangwe mushure memazuva manomwe ekunyudzwa mumvura. Nokudaro, inoshandiswa zvakanyanya mukudzivirira kwetambo. Zvisinei, ine nzvimbo yakaderera yekunyungudika. Kana yakashandiswa mumatambo, kukanganisa kwepamusoro kana kupfupi-kwedunhu kunogona kukonzera kukwira kwekushisa, zvichitungamira mukupfava uye kushanduka kwepolyethylene, zvichikonzera kukanganisa kwekudzivirira. Kuti ichengetedze zvakanakira zve polyethylene, inopinda muchinjika-inobatanidza, ichiwedzera kupikisa kwayo kupisa uye kupikisa kuputika kwekushushikana kwezvakatipoteredza, ichiita muchinjika-yakabatana polyethylene zvinhu zvakanakira insulation zvinhu.
3. Cable Stranding uye Kuputira Dhizaini
Chinangwa chetambo stranding uye kuputira ndechekudzivirira kuvharidzira, kuve neyakagadzika tambo yepakati, uye kudzivirira yakasununguka insulation uye mafirita, kuve nechokwadi kutenderera kwepakati. Thebhandi rekuputira rinomisa motoinopa zvimwe zvinodzivirira moto.
Zvishandiso zveCable Stranding uye Kupeta: Iyo yekuputira zvinhu ndeyepamusoro-murazvo-inodzoreredza.jira risiri rakarukwabhandi, rine simba rekusimba uye murazvo wekudzora indekisi isingasviki 55% oksijeni index. Iyo yekuzadza zvinhu inoshandisa murazvo-inodzoreredza inorganic mapepa tambo (mamineral tambo), ayo akapfava, ane okisijeni index isingasviki makumi matatu%. Zvinodiwa zvetambo stranding uye kuputira zvinosanganisira kusarudza hupamhi hwebhendi rekuputira zvichienderana nepakati dhayamita uye kona yebhendi, pamwe nekupetana kana kupindirana kwekuputira. Nzira yekuputira ndeyekuruboshwe. Mabhandi anoregedzesa moto anodiwa kuti aite mabhandi anodzoreredza moto. Kupisa kwekupisa kwezvinhu zvekuzadza kunofanirwa kuenderana nekushisa kwetambo yekushanda, uye kuumbwa kwayo hakufanirwe kupindirana zvakashatainsulation sheath zvinhu.Inofanira kubviswa pasina kukuvadza musimboti we insulation.
