Switching devices from DOLD offer optimal solutions for demanding applications in the areas of safety, monitoring, installation and power electronics.

This distribution unit features a modular design for flexible and convenient installation, supporting rapid assembly, disassembly and expansion. The enclosure is constructed from high-strength flame-retardant materials, offering superior dustproofing, moisture resistance, and corrosion resistance to ensure stable operation in demanding environments. Its internal layout is well-organised with clear wiring and ample ventilation channels, effectively enhancing the unit's service life and operational safety. Integrated intelligent monitoring interfaces provide real-time operational status feedback, facilitating remote maintenance and fault alerts. This solution is widely applicable across industrial, commercial, and other power distribution scenarios.

High-voltage switchgear possesses robust high-voltage adaptability, capable of reliably handling voltages of 10kV and above. Utilising premium insulating materials such as epoxy resin, it withstands high-voltage breakdown. Integrating components including circuit breakers, isolating switches, and instrument transformers, it enables control of high-voltage circuit switching, overload/short-circuit protection, and real-time monitoring of voltage and current. Certain configurations incorporate five-prevention interlock mechanisms to eliminate operational errors. A metal-sealed construction enhances dustproofing, waterproofing, and arc-resistant properties. Materials selected for high-voltage ageing resistance ensure long-term reliable operation. Adherence to standardised cabinet design facilitates seamless integration with high-voltage distribution systems.
