Dehler
Dehler Technology Co., Ltd., established in 2016, has rapidly emerged as a titan in the high and low voltage power equipment industry. Headquartered at No. 271, Weishiqi Road, Yanpan Economic Development Zone, Yueqing City—the global heart of electrical manufacturing—we command a strategic advantage in supply chain logistics and technical innovation.
Our specialized divisions, including the dedicated Electrical Complete Equipment Transformer Division at Jingba Road, focus on the R&D and production of critical infrastructure: high & low voltage switchgear, prefabricated substations, indoor & outdoor vacuum circuit breakers, and our flagship high-voltage isolating switches.
With a foundation built on "Survival through quality, development through technology," we serve mission-critical sectors including wind power generation, railway electrification, and petroleum industries, ensuring that every isolating switch meets rigorous international safety standards.
In the landscape of modern electrical grids, the High-Voltage Isolating Switch (also known as a Disconnector) is not merely a component; it is the ultimate guardian of maintenance safety. Unlike circuit breakers designed for interrupting fault currents, isolating switches provide a visible, physical gap in the circuit, ensuring that downstream equipment is truly de-energized.
Our switches utilize advanced blade geometry and contact materials to minimize residual arcing during operation, enhancing the lifespan of the equipment.
Mechanical and electromagnetic interlocking mechanisms prevent accidental operation under load, safeguarding personnel and hardware.
From the humid tropics to freezing high-altitude substations, our switches utilize specialized post insulators and anti-corrosion platings.
1. Renewable Energy Substations: With the rise of solar and wind farms, isolating switches must handle frequent switching cycles. Dehler's switches are optimized for the variable load patterns inherent in green energy grids.
2. Industrial Mining & Heavy Steel: In dusty, high-vibration environments like coal mines and steel mills, the integrity of the conductive path is critical. Our use of "Plum Blossom Contacts" ensures maximum surface contact and heat dissipation.
3. Metropolitan Smart Grids: Compact designs are essential for urban substations. Our indoor high-voltage disconnectors integrate seamlessly into SF6-insulated ring main units (RMU), saving up to 40% of floor space compared to traditional air-insulated models.
The future of isolating switches lies in "Intelligence." We are currently developing our "Smart Disconnector V3.0", which features:
As a leading China manufacturer, Dehler Technology leverages the "Yueqing Power Cluster." This unique ecosystem allows us to source raw copper, specialized insulators, and precision-engineered mechanical parts within a 50-mile radius, significantly reducing lead times and logistical costs.
From R&D to final assembly, we control every step. This ensures that the high-voltage isolating switch you receive has been tested against 20+ quality parameters in-house.
Our products adhere to IEC (International Electrotechnical Commission) standards, as well as specific regional certifications required for the European, SE Asian, and American markets.
Need a custom earthing switch or a specific mounting orientation? Our engineers can provide CAD designs and prototypes 3x faster than Western competitors.
Whether you are designing a high-altitude substation or upgrading a metropolitan power grid, Dehler Technology Co., Ltd. provides the engineering expertise and manufacturing power to ensure your project's success. Based in China, with a global perspective, we invite you to consult with our technical team for tailored isolating switch solutions.
