Dehler
In the era of Industrial 4.0 and the global energy transition, the vulnerability of sensitive electronic equipment to transient overvoltages has never been higher. As a leading Lightning Surge Protection Device (SPD) manufacturer, Dehler Technology addresses the critical need for systemic electrical resilience. Lightning strikes and switching surges are not merely "acts of God"; they are quantifiable risks that can be mitigated through high-precision engineering.
Understanding the roadmap of lightning protection technology.
The next generation of SPDs integrates IoT sensors for real-time health monitoring and "End of Life" (EOL) prediction, ensuring zero-latency maintenance in smart cities.
With the rise of PV systems and EV charging stations, SPDs must now handle DC surges up to 1500V, requiring advanced MOV (Metal Oxide Varistor) technology.
Moving from single-point protection to a coordinated "Type 1 + 2 + 3" strategy to protect everything from main transformers to sensitive end-user electronics.
Established in 2016, Dehler Technology Co., Ltd. is located in the Yanpan Economic Development Zone, Yueqing City. As a technology enterprise integrating R&D, production, sales, and service, we specialize in the high and low voltage power equipment industry.
Our expertise spans across high & low voltage switchgear, prefabricated substations, cable branch cabinets, indoor & outdoor vacuum circuit breakers, disconnectors, earthing switches, and load switches.
We strictly adhere to national and international quality systems (IEC 61643 standards), ensuring that our "survival through quality" philosophy is embedded in every component we manufacture. Our products serve critical sectors including steel mills, coal mining, communications, shipbuilding, and wind power generation.
Total isolation for sensitive servers using Type 3 SPDs at the rack level and Type 1+2 at the building entrance to prevent data loss during atmospheric discharges.
DC-specific surge protection rated for 1000V/1500V, designed to withstand the harsh environmental conditions of remote utility-scale PV installations.
Protection for railway electrification and signaling systems where switching transients from locomotives can cause catastrophic interference.
Dehler Technology provides more than just components; we provide ecosystem security. Our macro solutions integrate switchgear, transformers, and surge protection into a unified, resilient grid architecture.
Surge Arresters (High Voltage) are typically installed on the utility side to protect against lightning and large power surges. SPDs (Low Voltage) are designed to protect end-user equipment from transients within the building's electrical system.
Type 1 is for direct lightning strikes (installed at main service entrance). Type 2 is for indirect surges (distribution boards). Type 3 is for point-of-use protection (sensitive electronics).
Not necessarily. High-quality SPDs are designed to handle multiple surges. However, they feature visual or remote indicators that signal when the internal components have degraded and the module needs replacement.
All Dehler products are tested according to IEC 61643-11 for low-voltage surge protection and meet or exceed national GB standards for electrical safety and performance.
