Dehler
Established in 2016, Dehler Technology Co., Ltd. has rapidly emerged as a cornerstone of the electrical infrastructure industry. Based in the Yanpan Economic Development Zone, Yueqing City, our facility integrates R&D, advanced manufacturing, and global logistics to serve the most demanding power generation and distribution sectors.
As a leading Silicon Carbide Lightning Arrester manufacturer, we leverage deep technical expertise to produce equipment that meets IEC standards. Our specialized divisions handle everything from prefabricated substations to high-precision electrical components, ensuring that every product—whether it’s a 10kV switchgear or a specialized disconnector—is built for longevity and extreme reliability.
Understanding Information Gain in Lightning Protection Systems
Silicon Carbide (SiC) lightning arresters utilize non-linear resistor blocks with high thermal stability. Unlike modern Zinc Oxide (ZnO) variants, SiC arresters traditionally feature a series of spark gaps. This combination offers a unique "quenching" capability that is still preferred in specific industrial applications where high mechanical strength and extreme voltage stability are paramount.
The core innovation in our SiC arresters lies in the resistance-voltage curve. Under normal operating voltages, the resistance is exceptionally high. However, upon a lightning surge or switching impulse, the resistance drops instantaneously, providing a low-impedance path to ground, effectively "clamping" the voltage to safe levels for downstream transformers and switchgear.
Modern SiC arresters by Dehler are housed in high-grade porcelain or composite silicone housings. Our manufacturing process involves vacuum-filling and nitrogen-sealing to prevent moisture ingress, which is the leading cause of arrester failure in coastal or high-humidity environments.
Custom SiC solutions for wind turbine nacelles and solar farm collectors, designed to withstand high-altitude lightning risks and frequent switching operations.
Heavy-duty arresters optimized for 25kV traction networks, offering robust protection against the steep-front surges typical in high-speed rail systems.
Providing essential surge protection for steel mills and coal mines where electrical noise and voltage fluctuations are constant threats to sensitive PLC systems.
Dehler is pioneering the use of hydrophobic cycloaliphatic epoxy (HCEP) resins to further reduce the weight of outdoor arresters while enhancing tracking resistance in saline environments.
Integration of Narrowband IoT (NB-IoT) sensors into the arrester base to provide real-time leakage current data to utility control rooms, enabling "Condition-Based Maintenance."
Research into nanotechnology to create finer SiC grain structures, allowing for higher energy absorption density and more compact physical footprints.
Silicon Carbide (SiC) arresters require a spark gap to isolate the resistor from the line voltage under normal conditions, whereas Zinc Oxide (ZnO) arresters are gapless. SiC is often valued for its historical reliability and robustness in specific legacy systems and high-energy industrial applications.
Based on IEEE guidelines, we recommend a visual inspection annually and a comprehensive diagnostic test (including insulation resistance and leakage current measurements) every 3-5 years, depending on the severity of the local lightning environment.
