Description
In 10kV outdoor power distribution networks, atmospheric overvoltage caused by lightning strikes and switching overvoltage induced by switch operations are the primary causes of insulation breakdown and burnout of core equipment such as transformers, cable terminations, and pole-mounted switches. Conventional surge arresters suffer from issues like gap aging, high residual voltage, and frequent maintenance, making them difficult to adapt to complex outdoor scenarios with coastal salt spray, heavy pollution, and large temperature differences. The HY5WS-17/50 10kV outdoor high-voltage zinc oxide surge arrester, with gapless zinc oxide varistors as the core and an integrally molded composite silicone rubber housing, perfectly addresses these pain points, providing an all-weather, maintenance-free overvoltage protection barrier for outdoor power distribution equipment.
The product adopts a gapless structural design, eliminating the aging and adjustment processes of traditional gaps. It has a nanosecond-level response speed, which can conduct immediately when overvoltage occurs. The residual voltage is stably controlled at ≤50kV, effectively preventing damage to equipment insulation. The high-quality zinc oxide varistor formula offers large current-handling capacity and strong anti-aging performance. 正常運作情況下, the leakage current is extremely small, almost not consuming system energy. The composite silicone rubber housing is manufactured using an integral molding process, featuring excellent sealing performance with no air gaps or leakage. The shed design increases the creepage distance and provides excellent hydrophobic migration performance. Even if dust and salt spray adhere to the surface, it can maintain good insulation without manual cleaning, significantly reducing operation and maintenance costs.
This surge arrester supports flexible installation methods, including vertical/horizontal outdoor pole-mounted installation, with simple wiring: the upper end is connected to the 10kV high-voltage line, and the lower end must be reliably grounded. It is suitable for a temperature range of -40°C to +70°C and an altitude of ≤2000m (customizable for high altitudes), and can operate stably for a long time in harsh environments such as coastal salt spray, industrial dust, and strong ultraviolet rays. It is widely used in 10kV distribution transformers, 環網櫃, cable distribution boxes, 架空線, rural power grid renovation, and industrial park power distribution systems. It complies with standards including GB 11032-2018, 國際電工委員會 60099-4, and JB/T 8952, with all performance indicators meeting national and international specifications.
In 10kV outdoor power distribution networks, atmospheric overvoltage from lightning strikes and switching overvoltage from equipment operations are the leading causes of insulation breakdown and damage to critical assets such as transformers, cable terminations and pole-mounted switches. Traditional arresters often face issues like gap degradation, high residual voltage and intensive maintenance needs, which make them unsuitable for harsh outdoor environments with coastal salt spray, heavy pollution and extreme temperature fluctuations. The HY5WS-17/50 10kV outdoor high-voltage zinc oxide surge arrester, featuring gapless zinc oxide varistors and an integrally-molded composite silicone rubber housing, effectively resolves these challenges, providing an all-weather, low-maintenance overvoltage protection shield for outdoor distribution equipment.
The arrester adopts a gapless design, eliminating the aging and adjustment work associated with conventional gaps, and achieves nanosecond-level response speed, conducting instantaneously once overvoltage occurs. The residual voltage is stably limited to ≤50kV, which effectively protects the insulation of connected equipment. The premium-formulated zinc oxide varistors offer high current-handling capacity and excellent anti-aging performance; under normal operating conditions, the leakage current is extremely low, consuming negligible system energy. The composite silicone rubber housing is produced via one-step integral molding, ensuring superior sealing without air gaps or leakage risks. The skirt design increases the creepage distance and delivers outstanding hydrophobic migration performance—even if dust or salt spray accumulates on the surface, the arrester maintains reliable insulation without the need for manual cleaning, thus greatly reducing operational and maintenance costs.
This arrester supports flexible installation, allowing vertical or horizontal mounting on outdoor poles. Wiring is straightforward: the upper terminal connects to the 10kV high-voltage line, while the lower terminal must be reliably grounded. It can operate stably in temperatures ranging from -40°C to +70°C and at altitudes up to 2000 meters (customized versions are available for high-altitude areas), and performs consistently in harsh outdoor environments such as coastal salt spray zones, industrial dust areas and regions with strong ultraviolet radiation. It is widely applied in 10kV distribution transformers, 環網櫃, cable distribution boxes, 架空線, rural power grid upgrades and industrial park distribution systems. It complies with GB 11032-2018, 國際電工委員會 60099-4 and JB/T 8952 標準, with all performance parameters meeting both national and international requirements.
