220 kV ɗaya mai haguwar gida (na'ura)

Na gida na kudin:
Yana amfani da casting a resin epoxy ko kudin stress cone na yankin don inganta tattalin mafi yawan electric field da capacity na local discharge ≤ 5pC (IEC 60840 standard)
Kudin shekaru masu waterproof tape, na protection level IP68, ya fi dacewa da cikin yankunan da ke da ruwa kamar direct burial da tunnels
Kyakkyawar electrical:
Rated voltage 220kV (Um=252kV), yana iya amfani a cable cross-section of 250~2500mm ², short-circuit current withstand capacity ≥ 25kA/3s, insulation resistance ≥ 10 ¹² Ω, dielectric loss ≤ 0.01 (1kHz)

Scenarios na amfani
Engineering na karamin sarki: ana amfani a matsayin intermediating connection of 220kV cable lines, wanda yana iya amfani a direct burial, conduit ko cable trench laying
Station na karamin sarki na energy: an fito da wind power da photovoltaic booster stations, wadannan suna bukatar da su ci gaba a kan operation na outdoor ta hanyar lokaci (kamar salt spray da vibration)
Grid na karamin sarki: Interconnection na substations ko projects na ring network suna bukatar da detection na partial discharge na regular (kamar PD3302 ultra-high frequency detector)

Standards na Technical da Certification
Standard: Yana ci gaba da GB/T 12706.3-2008 (220kV Cross linked Polyethylene Insulated Cable Accessories)
Certification: Ya kamata a lalace PSE, CE ko State Grid supplier qualification audit
