In the era of Smart Grids and Industry 4.0, Grounding Lightning Arresters serve as the first line of defense against transient overvoltages. We provide end-to-end protection for critical infrastructure, integrating metal-oxide varistor (MOV) technology to ensure zero-gap performance. Our solutions are designed to mitigate risks from atmospheric lightning strikes and internal switching surges, preserving the longevity of multimillion-dollar transformer assets.
The global surge protection market is shifting toward higher durability and predictive maintenance. As leading exporters, we track regional demands—from the high-humidity environments of Southeast Asia to the extreme temperatures of the Middle East. Our products comply with IEC 60099-4 and IEEE C62.11 standards, ensuring seamless integration into any international grid specification.
We don't just ship hardware; we provide compliance assurance. Our engineering team offers localized application support, including insulation coordination studies and earthing system design consultations. This ensures that every lightning arrester installed meets local grid code requirements and environmental safety regulations.
Dehler Technology Co., Ltd., established in 2016, is a technology enterprise integrating R&D, production, sales, and service, specializing in the high and low voltage power equipment industry. Based in Yueqing City, we specialize in high & low voltage switchgear, Prefabricated substations, cable branch cabinets, and diverse electrical components.
We adhere to the business philosophy of "survival through quality, development through technology, and efficiency through management." Our business covers power generation, railway electrification, steel mills, wind power, and electrical automation.
In heavy industrial sectors like coal mining and steel mills, lightning arresters must withstand frequent switching surges. Our heavy-duty porcelain and polymeric housed arresters are optimized for high-pollution environments, featuring superior creepage distances.
Renewable sites are often located in open areas with high lightning flash densities. Our DC and AC arresters are specifically tuned for solar combiner boxes and wind turbine nacelle protection, ensuring continuous uptime for green energy generation.
Railway systems require lightning arresters with high mechanical strength and vibration resistance. We provide specialized traction power supply protection solutions that meet the rigorous standards of high-speed rail networks.
The future of lightning protection lies in Smart Monitoring. Our R&D is currently focusing on IoT-enabled surge counters that transmit real-time leakage current data to cloud platforms, enabling "Condition-Based Maintenance" (CBM) for global utility companies.
Over the years, our company has diversified its product offerings and continuously upgraded its services, earning widespread acclaim. We strictly adhere to national quality system standards, which plays a crucial role in cultivating a positive corporate image.
Strengthening quality management is a prerequisite for increasing market share. We continuously leverage a systematic and standardized quality management system as a strong foundation to advance our company's capabilities.
“High-quality products, superior technology, and impeccable service" are the goals pursued by Dehler. Facing the opportunities and challenges of international industrial electrical development, we have formulated a new development strategy and established a systematic, large-scale production model.
Porcelain arresters are traditional, offering high rigidity and long-term weather resistance but are prone to shattering. Polymer (silicone rubber) arresters are lightweight, shatter-proof, and offer superior hydrophobic properties, making them ideal for high-pollution or seismic areas.
Selection is based on the system's Maximum Continuous Operating Voltage (MCOV). The arrester's duty cycle rating must be higher than the temporary overvoltage (TOV) the system might experience during a fault.
Yes. As a leading factory, we provide custom terminal connectors, varying creepage distances, and specialized mounting brackets to meet the unique structural requirements of global utility providers.
Under standard operating conditions and proper installation, our arresters are designed for a service life exceeding 20 years, supported by our high-purity Zinc Oxide varistor technology.
