DC Deicers

The DC deicing and SVC device utilizes high-power electronic components to generate direct current, which heats the wires to melt accumulated ice on power lines. This device is highly reliable, with minimal impact on the system, and is suitable for deicing large-capacity, long-distance power lines.
