Pangkat ng disenyo:
Nagpapahayag ng paggamit ng epoxy resin casting o prefabricated stress cone structure upang matiyak ang pantay na distribusyon ng elektrikong field at lokal na kapasidad ng discharge ≤ 5pC (IEC 60840 standard)
Metal sheath at waterproof tape seal, may lebel ng proteksyon na IP68, angkop para sa mga basang kapaligiran tulad ng direct burial at tunnels
Pangkat ng electrical performance:
Rated voltage 220kV (Um=252kV), angkop para sa cable cross-section na 250~2500mm ², kakayahan ng short-circuit current na ≥ 25kA/3s, insulation resistance na ≥ 10 ¹² Ω, dielectric loss na ≤ 0.01 (1kHz)
Mga scenario ng aplikasyon
Power engineering: ginagamit para sa intermediate connection ng 220kV cable lines, sumusuporta sa direct burial, conduit o cable trench laying
Bagong enerhiyang power station: equipped na may wind power at photovoltaic booster stations, na kailangan ang pagsunod sa long-term outdoor operation requirements (tulad ng salt spray at vibration)
Urban power grid: Substation interconnection o ring network projects na nangangailangan ng regular na detection ng partial discharge (tulad ng PD3302 ultra-high frequency detector)
Technical Standards at Certification
Standard: Sumusunod sa GB/T 12706.3-2008 (220kV Cross linked Polyethylene Insulated Cable Accessories)
Certification: Kailangan lumampas sa PSE, CE o State Grid supplier qualification audit
