Tumira ImeyiliTambo dzemagetsi dze12.7-22kV-XLPE dzakadzivirirwa nemagetsi epakati nepakati (insulated medium-voltage cables) dzinowanzo shandiswa pamagetsi ekuparadzira magetsi uye pamagetsi ekuwedzera munzvimbo dzakasiyana-siyana. Kudzivirira kwacho kunobvumira kuvigwa zvakananga kudzivirira kuvhunduka netsaona kwemagetsi uye kukuvara. Rudzi rweAS/NZS 12.7-22kV-XLPE rune tambo dzemagetsi dzepakati nepakati dzakagadzirwa maererano neAustralian/New Zealand Standard AS/NZS 1429.1. Dzakakodzera kuiswa mumagetsi emagetsi munzvimbo dzese dziri mukati nekunze, uye dzinogona kuiswa mumigero yemagetsi, pamatireyi etambo, kana kuvigwa zvakananga pasi pevhu. Dzakakodzera masisitimu emagetsi ane fault current anosvika 10kA/1 second. Zvivakwa zvine fault current qualitative yakakwira zviripo kana zvakumbirwa.
Kuvaka:
Mutyairi:Mhangura kana aruminiyamu, yakatenderera yakavharirwa, yakatenderera yakamanikana.
Kudzivirira:XLPE kana TR-XLPE kana EPR.
Kudzivirira simbi:Kudzivirira waya dzemhangura (CWS), Kudzivirira tepi dzemhangura (CTS).
Muhara:Mudziyo wealuminium wakasanganiswa necorrugated (CAS), Mudziyo wemhangura wakasanganiswa necorrugated (CCU), Simbi isina ngura yakasanganiswa necorrugated (CSS).
Zvombo:Kudzivirira waya dzearuminiyamu (AWA), Kudzivirira waya dzesimbi (SWA), Kudzivirira waya dzesimbi dzisina ngura (SSWA).
Kudzivirirwa kwemuchenje:Chivharo chenylon chePoliamide, Tepi yebhuranzi mbiri (DBT), Cypermethrin.
Tambo dzekuisa:12D (PVC chete) 15D (HDPE).
Panguva yekuiswa:18D (PVC chete) 25D (HDPE).
Tembiricha yemhando yepamusoro:
Tembiricha shoma yekuisa: 0°C
Kupisa kwakanyanya kushanda: +90°C
Tembiricha shoma yekushanda: -25°C
Tambo dzeMedium Voltage dzakagadzirwa nemaitiro adzo:
Kuti ishande zvakanaka uye igare kwenguva refu, tambo yega yega yeMV inofanira kugadziriswa zvichienderana nekuiswa kwayo asi pane dzimwe nguva panodiwa tambo yakagadzirwa nenzira chaiyo. Nyanzvi dzedu dzetambo yeMV dzinogona kushanda nemi kugadzira mhinduro inoenderana nezvamunoda. Kazhinji, kugadzirisa zvinhu kunokanganisa saizi yenzvimbo yesimbi, iyo inogona kugadziriswa kuti ichinje kugona kwe short circuit uye zvinhu zve earthing.
Muzviitiko zvese, ruzivo rwehunyanzvi rwunopihwa kuratidza kukodzera uye zvinodiwa kuti zvigadzirwe. Mhinduro dzese dzakagadzirirwa iwe dzinofanira kuongororwa zvakanyanya muMV Cable Testing Facility yedu.
