In the complex landscape of medium and high-voltage electrical engineering, the Three Pole Isolator Switch (also known as a disconnector) serves as the fundamental safety mechanism. Unlike circuit breakers that interrupt fault currents, these switches provide a visible gap, ensuring equipment is completely de-energized for maintenance. As global energy demands shift toward decentralization, the role of high-integrity isolation technology has never been more critical.
Modern power grids are integrating AI-driven monitoring. Our three-pole isolators are designed for seamless integration with SCADA systems, providing real-time positional feedback for smart grid management.
With the surge in data centers and EV charging infrastructure, the demand for reliable 12kV to 40.5kV isolation switches is growing at a CAGR of 6.5%. Manufacturers are now focusing on reduced maintenance cycles and environmental resilience.
Transitioning from pure mechanical operation to "Smart Isolation." Future models include embedded sensors for thermal imaging and vibration analysis to predict wear before failure occurs.
Dehler Technology Co., Ltd., established in 2016, is a premier technology enterprise specializing in the R&D, production, and service of high and low voltage power equipment. Located in the Yanpan Economic Development Zone of Yueqing City, our facilities include a dedicated transformer division and advanced switchgear assembly lines.
Our core expertise lies in the production of high & low voltage switchgear, prefabricated substations, indoor & outdoor vacuum circuit breakers, and specialized Three Pole Isolator Switches. We adhere to the philosophy of "Survival through quality, development through technology," ensuring every component meets rigorous international standards.
Our manufacturing process adheres to IEC 62271-102 standards for alternating current disconnectors and earthing switches. Each unit undergoes:
✓ Mechanical endurance testing (Up to 2000 cycles)
✓ Short-time withstand current tests
✓ Dielectric testing (Lightning impulse & power frequency)
✓ Temperature rise monitoring under full load
Over the years, Dehler has diversified its product offerings and continuously upgraded its services, earning widespread acclaim. We have established long-term, stable partnerships with numerous suppliers and distributors globally. Strengthening quality management is our prerequisite for increasing market share. We strictly adhere to national quality system standards, cultivating a positive corporate image through reliability.
Facing the opportunities and challenges of international industrial electrical development, we have formulated a new strategy focusing on large-scale production models and rapid resource integration. Our goals are simple: "High-quality products, superior technology, and impeccable service."
A circuit breaker is designed to break fault currents (short circuits), while a three-pole isolator is used to provide a visible safety gap for maintenance after the circuit has been opened by a breaker. It cannot interrupt load current unless specifically rated as a "load break switch."
Yes, we manufacture both indoor and outdoor variants. Outdoor models feature specialized porcelain or silicone rubber insulators and stainless-steel housings to prevent corrosion from rain, humidity, and UV exposure.
We leverage decades of collective engineering experience (Experience), employ PhD-level R&D staff (Expertise), hold international quality certifications (Authoritativeness), and offer comprehensive warranties and after-sales support (Trustworthiness).
Absolutely. We offer customization for terminal connectors, operating mechanisms (manual vs. motorized), and auxiliary contacts to ensure compatibility with your existing substation architecture.
Based in China, with a global perspective, our company sincerely collaborates with friends from all walks of life. We welcome all parties to visit and inquire for shared success.
