In the modern electrical grid infrastructure, the vulnerability of power lines to lightning strikes is compounded by environmental factors such as industrial pollution, salt spray in coastal areas, and heavy humidity. Anti-Pollution Lightning Arresters represent the pinnacle of overvoltage protection technology, specifically engineered to maintain insulation integrity where standard arresters fail.
Conventional porcelain arresters often suffer from "pollution flashover" – a phenomenon where conductive contaminants on the surface lead to a sudden discharge. Our China-made anti-pollution arresters utilize high-hydrophobicity silicone rubber housings, increasing the specific creepage distance and ensuring stable operation even in the heaviest industrial smog or saline environments.
At the heart of every Dehler lightning arrester is the Zinc Oxide (ZnO) varistor. Unlike older silicon carbide arresters, ZnO components offer superior non-linear volt-ampere characteristics. This means:
In high-pollution zones (Class IV or Class V), the ratio of creepage distance must exceed 31mm/kV. Our exported models typically feature 35mm/kV to 45mm/kV to provide a "safety buffer" for global EPC projects in the Middle East and Southeast Asia.
| Parameter | Standard Arrester | Anti-Pollution Arrester (Dehler) | Benefit |
|---|---|---|---|
| Housing Material | Porcelain | Polymer / Silicone Rubber | Shatter-proof & Hydrophobic |
| Creepage Distance | 20-25 mm/kV | 31-45 mm/kV | Flashover prevention |
| Weight | High (Heavy) | Low (Lightweight) | Easier Installation |
| Maintenance | Periodic Cleaning | Self-cleaning properties | Lower OPEX |
Established in 2016 and located in the Yanpan Economic Development Zone, Yueqing City, Dehler Technology Co., Ltd. is a high-tech enterprise integrating R&D, production, sales, and service. We specialize in the high and low voltage power equipment industry, offering a comprehensive portfolio from switchgear to state-of-the-art surge arresters.
Our philosophy of "survival through quality, development through technology" has led us to serve critical sectors including power generation, railway electrification, steel mills, and renewable energy (wind and solar).
Wind farms and solar plants are often located in coastal or desert areas. Global demand for anti-pollution arresters is surging as EPCs prioritize grid resilience against extreme weather.
The next generation of arresters includes IoT sensors to monitor leakage current and discharge counts in real-time, moving from reactive to predictive maintenance.
Strict adherence to IEC 60099-4 and IEEE C62.11 is no longer optional. Dehler's products meet and exceed these international benchmarks for global export.
Over the years, our company has diversified its product offerings and continuously upgraded its services, earning widespread acclaim. We have a strong reputation and established long-term, stable partnerships with numerous suppliers and distributors. We strictly adhere to national quality system standards, which plays a crucial role in cultivating a positive corporate image.
“High-quality products, superior technology, and impeccable service" are the goals pursued by Dehler. Facing the opportunities and challenges of international industrial electrical development, our company has formulated a new development strategy and rapidly established a systematic, large-scale production model.
For large-scale infrastructure projects, we provide Total Surge Protection Coordination (TSPC). This involves analyzing the insulation coordination of the entire substation, including switchgear, transformers, and bushings, to ensure the arrester provides the maximum margin of protection.
We understand that different regions have varying electrical codes (e.g., ANSI vs. IEC). Dehler provides full documentation, type test reports from KEMA/CPRI equivalents, and localized technical support to ensure seamless integration into foreign grids.
