Modern industrial facilities rely on sensitive 3-phase electronics. A single lightning strike or switching surge can cause catastrophic failure. As a leading 3 Phase Lightning Arrester Supplier, we provide Metal Oxide Varistor (MOV) technology that reacts in nanoseconds to shunt excess voltage to the ground.
The global push for "Industry 4.0" and "Smart Grids" has increased the vulnerability of power systems. We analyze global electrical grids to ensure our arresters handle the high nominal discharge currents (In) required in regions with high isokeraunic levels (lightning frequency).
Our products adhere to international standards like IEC 61643-11 and IEEE C62.41. Trustworthiness is built through rigorous testing of thermal stability, residual voltage performance, and enclosure durability against harsh environmental conditions.
Established in 2016, Dehler Technology Co., Ltd. is a technology enterprise integrating R&D, production, sales, and service. We specialize in the high and low voltage power equipment industry, located in the Yueqing Economic Development Zone.
Our division specializes in the production of high & low voltage switchgear, prefabricated substations, and essential electrical components like 3-phase lightning arresters. We adhere to the business philosophy of "survival through quality, development through technology, and efficiency through management."
Implementation of high-gradient Zinc Oxide (ZnO) disks to reduce arrester size while increasing energy absorption capacity for high-voltage applications.
Integrating smart sensors to monitor leakage current and discharge count in real-time, enabling predictive maintenance before a failure occurs.
Developing eco-friendly polymer housings that offer superior UV resistance and hydrophobicity, extending the service life to over 25 years.
Our custom 3-phase lightning arresters are engineered for diverse environments, ensuring business continuity across sectors.
Protecting large motor drives and CNC machinery from grid switching transients in industrial zones across Southeast Asia and Europe.
Optimized for solar PV inverters and wind turbine nacelles where high-altitude lightning exposure is a constant threat.
Ensuring the safety of HVAC systems, elevators, and data centers in urban skyscrapers through multi-level Type 1+2 surge protection.
Reliable surge protection for railway signaling and electrification systems, meeting strict safety and vibration standards.
Type 1 arresters are designed to handle direct lightning strikes (10/350 μs waveform) and are typically installed at the main service entrance. Type 2 arresters protect against indirect strikes and switching surges (8/20 μs waveform). As a premier supplier, we often recommend Type 1+2 combined units for comprehensive protection.
Extreme temperatures can degrade the MOV disks. Our custom arresters feature high-quality polymer or porcelain housing with excellent thermal dissipation properties, ensuring stable operation from -40°C to +70°C, suitable for both Arctic and Equatorial climates.
Every electrical grid has unique characteristics (TT, TN-S, TN-C-S grounding systems). A custom-configured 3-phase arrester ensures the Maximum Continuous Operating Voltage (Uc) is perfectly matched to your local nominal voltage, preventing premature failure or safety hazards.
While designed for longevity, we recommend inspection after every major lightning season or significant grid event. Our IoT-enabled models provide "end-of-life" indicators, removing the guesswork from maintenance schedules.
Over the years, Dehler has diversified its product offerings and continuously upgraded its services. We strictly adhere to national quality system standards, which not only strengthens our overall strength but also plays a crucial role in cultivating a positive corporate image.
Based in China, with a global perspective, our company sincerely collaborates with friends from all walks of life. We provide localized support and customized engineering to meet your specific compliance requirements.
