Description

Technical Field

[0001] This utility model relates to the field of insulating pull rods, specifically an adjustable insulating pull rod. Background Technology

[0002] Link rods, also known as switch rods, insulating rods, or insulating pull rods, consist of three parts: a working head, an insulating rod, and a handle. Insulating pull rods are commonly used operating tools in power systems, primarily for live-line operations on high-voltage electrical equipment, such as opening and closing disconnect switches and drop-out fuses. During power operations, different operating scenarios and equipment locations require different lengths for the insulating pull rods. Most existing insulating pull rods are of fixed length, with a few extending by splicing multiple rod sections. When operating equipment at a greater distance, it is necessary to replace the insulating pull rod with a longer one or temporarily add an extra rod section, increasing the complexity and time cost of the operation and reducing personnel efficiency.
