10 kV-ko kanpoko banaketa sarean，传统避雷器更换必须停电，不仅影响用户供电可靠性，还大幅增加运维成本；而雷击、开关操作引发的过电压，又极易造成变压器、kable amaiera、Nukleoko ekipoen isolamendu-matxura, hala nola zutoinetan muntatutako etengailuak。HY5WS-17/50DL-TB 10kV 可卸式跌落避雷器，以 “免停电运维 + 故障自动隔离 + 高效过压防护” 为核心，完美解决这两大痛点。

产品采用无间隙氧化锌阀片结构，Erantzun-abiadura nanosegundo mailara iristen da，残压低、Emari ahalmen handia，正常运行时泄漏电流仅微安级，不影响系统工况；遭遇过电压瞬间迅速导通，将过电压能量导入大地。独特的跌落式机构 + TB 热爆脱离器，让运维人员可用绝缘操作杆在带电状态下轻松投切、更换，特别适合机场、Ospitalea、商业区等不可轻易停电的场所。

复合硅橡胶外套采用整体模压工艺，密封性能优异，防护等级高，具备抗紫外线、耐盐雾、防凝露、抗污闪的特性，可在 – 40℃~+70℃极端温度下长期稳定运行。安装方式为户外水平 / 垂直柱上安装，Kableatu sinplea，接地可靠；故障时的翻落动作直观，便于巡检人员快速定位并处理，大幅缩短抢修时间。

相比普通固定避雷器，本品不仅防护性能达标，更显著提升了配电网的供电连续性与运维效率，广泛应用于 10kV 户外柱上变压器、Eraztun unitate nagusia、Kable-adar-kutxa、架空线路终端，是电网改造与新建项目的首选防雷设备。

Kanpoko 10 kV-ko potentzia banatzeko sareetan, replacing conventional surge arresters always requires power outages, which not only impairs power supply reliability for end-users but also significantly increases operation and maintenance costs. Meanwhile, overvoltage caused by lightning strikes and switch operations can easily lead to insulation breakdown of core equipment such as transformers, kableen amaierak, eta zutoinetan muntatutako etengailuak. The HY5WS-17/50DL-TB 10kV detachable drop-out surge arrester addresses these two critical pain points with its core advantages: maintenance without power interruption, automatic fault isolation, and high-efficiency overvoltage protection.

The arrester adopts a gapless zinc oxide varistor design with nanosecond-level response, low residual voltage, and large current-handling capacity. Funtzionamendu arruntean, the leakage current is only at the microampere level, which does not affect the system’s working conditions. When an overvoltage occurs, the varistors conduct instantaneously, diverting the overvoltage energy to the ground. The unique drop-out mechanism combined with the TB thermal detacher allows operators to safely switch, inspect and replace the arrester while the line is energized using an insulated operating rod. This feature is especially critical for locations that cannot afford unplanned outages, such as airports, ospitaleak, and commercial districts.

The composite silicone rubber housing is manufactured via integral molding, ensuring excellent sealing performance and a high protection rating. It offers UV resistance, gatz spray erresistentzia, anti-condensation, and anti-pollution flashover capabilities, enabling long-term stable operation in extreme temperatures ranging from -40°C to +70°C. It is designed for horizontal or vertical outdoor pole-mounted installation, with simple wiring and reliable grounding. The visible flipping action during a fault allows inspectors to quickly locate and resolve issues, significantly reducing repair time.

Compared with standard fixed arresters, this product not only meets all protection performance requirements but also greatly enhances the power supply continuity and operational efficiency of the distribution network. It is widely used in 10kV outdoor pole-mounted transformers, eraztun-unitate nagusiak, kable banaketa-kutxak, and overhead line terminals, making it the preferred lightning protection equipment for power grid renovation and new construction projects.
