Brand | Switchgear parts |
Model NO. | 220kV composite outdoor cable terminal |
Rated voltage | 220kV |
Series | YJZWFY |
Product Definition and Core Features
Structural design: Using composite sleeves (silicone rubber/epoxy resin composite material) instead of traditional porcelain sleeves, combining mechanical strength and weather resistance, reducing weight by 30% to 50%
Electrical performance:
Rated voltage of 220kV, suitable for cable cross-section of 400-2500mm ², local discharge capacity ≤ 5pC (IEC 60840 standard). Built in stress cone structure optimizes electric field distribution and reduces the risk of interface breakdown
Environmental adaptability:
Anti pollution level reaches level IV (GB/T 5582), suitable for harsh environments such as coastal areas and high altitudes, with a working temperature range of -40 ℃~+90 ℃ and an anti UV aging life of ≥ 30 years
Typical application scenarios
In the field of new energy, specialized terminals for offshore wind power need to meet salt spray corrosion and vibration conditions
Urban power grid: used for 220kV cable lift off terminal stations, improving safety through SF6 gas sealing (patented technology)
Substation interconnection: GIS plug-in terminal, supporting quick installation and multiple insertions (compliant with IEC 60859 standard)
