High-performance components engineered for Sofia’s industrial zones and the Balkan power grid.
Bulgaria is currently witnessing a massive transformation in its energy landscape. As a key member of the European Union, the nation is aggressively pursuing the "Integrated Energy and Climate Plan" (INECP), which mandates a significant upgrade of its aging Soviet-era transmission infrastructure to accommodate modern renewable energy sources.
Information Gain: Unlike Western Europe, the Bulgarian market requires a unique blend of rugged legacy compatibility and smart-grid ready IEC standards. Manufacturers who understand the specific topography—from the industrial hubs in Plovdiv to the massive solar parks in Stara Zagora—gain a decisive edge.
Our role as a premier electrical accessories manufacturer is to bridge this gap. We provide components that meet CE marking requirements and IEC 62271 standards, ensuring seamless integration into the Bulgarian Electricity System Operator (ESO EAD) network.
Bulgaria’s transition to solar and wind requires advanced Reactive Power Compensation and Voltage Regulation. Our CKSG reactors and BSMJ capacitors are specifically designed to stabilize grids fluctuating with PV input.
The manufacturing sector in regions like the Maritsa basin is shifting toward automation. This creates a high demand for Molded Case Circuit Breakers (MCCB) and Vacuum Circuit Breakers (VCB) that support IoT monitoring.
Bulgaria serves as the strategic entry point for Chinese electrical components into the EU. By sourcing from a Yueqing-based leader like Dehler, Bulgarian companies benefit from the world's most mature supply chain with EU-compliant certification.
Established in 2016, Dehler Technology Co., Ltd. is a technology enterprise integrating R&D, production, sales, and service, specializing in the high and low voltage power equipment industry. Based in Yueqing, the electrical capital of China, we operate multiple divisions including a specialized transformer division.
We specialize in the production of high & low voltage switchgear, Prefabricated substations, cable branch cabinets, indoor & outdoor vacuum circuit breakers, disconnectors, earthing switches, load switches, and various electrical components.
