In modern industrial grids, the Low-Voltage Isolating Switch (Disconnector) serves as the primary safeguard. Unlike circuit breakers, they provide a visible isolation gap, ensuring maintenance personnel can work on downstream equipment with absolute certainty of zero electrical energy.
Our switches are engineered for high thermal stability and minimal contact resistance. By utilizing silver-plated copper contacts, we reduce energy loss and heat generation, which is critical for 24/7 industrial operations.
Adhering to IEC 60947-3 and GB standards, our products are designed for global export, meeting the stringent requirements of European, American, and Southeast Asian power grids.
Dehler Technology Co., Ltd., established in 2016, is a cornerstone of the Yueqing electrical cluster. Operating across two specialized divisions—our main headquarters at No. 271 Weishiqi Road and our Transformer Division at No. 178 Jingba Road—we have built an integrated ecosystem for R&D, production, and global service.
We specialize in the high and low voltage power equipment industry, including:
Chinese manufacturers like Dehler benefit from a complete supply chain. From raw copper processing to precision mold injection and automated assembly, every step is localized, reducing lead times by 30-40% compared to Western counterparts.
China is now a leader in Smart Grid Integration. Our isolating switches are increasingly equipped with IoT sensors to monitor contact temperature and mechanical wear, providing predictive maintenance data to central control systems.
Producing for both the massive domestic infrastructure projects and global markets allows us to maintain high-quality standards while offering competitive pricing that benefits international EPC contractors and distributors.
Steel mills and mining operations where robust, dust-proof isolation is mandatory for safety.
Photovoltaic (PV) grid-connected cabinets requiring high-voltage DC isolation capabilities.
Ensuring redundant power paths can be safely isolated for maintenance without downtime.
Corrosion-resistant switchgear for marine environments and offshore platforms.
As the world pivots toward ESG goals, isolating switch manufacturers are focusing on environmentally friendly materials. This includes lead-free alloys and recyclable housing materials. Furthermore, the integration of Digital Twin technology allows engineers to simulate switch performance under extreme loads before physical installation.
At Dehler, we are accelerating our resource integration to offer Intelligent Power Distribution. Our latest GCS drawer-type switchgear now features modular isolating units that can be hot-swapped, drastically reducing MTTR (Mean Time To Repair).
Don't just look at Voltage (Ue) and Current (Ie). Ensure you evaluate the Rated Short-time Withstand Current (Icw). A higher Icw ensures the switch doesn't weld shut during a short-circuit fault before the breaker trips.
Initial purchase price is only 30% of the cost. High-quality isolating switches from Dehler reduce long-term costs through lower contact maintenance and energy efficiency (low Power Dissipation).
Work with manufacturers who have experience in international logistics. We handle all documentation, ensuring smooth customs clearance and compliance with local electrical codes.
Strengthening quality management is a prerequisite for increasing market share. We continuously leverage a systematic and standardized quality management system as a strong foundation to advance our company's capabilities. Therefore, we strictly adhere to national quality system standards, which plays a crucial role in cultivating a positive corporate image.
The company has continuously upgraded its diversified sales products and services over the years, enjoying a good reputation and credibility among consumers, and has established long-term stable cooperative relationships with multiple supporting manufacturers and agents.
