Spiral Wrapping Characteristics Of Pre-twisted Wire In Transmission Line Structures

The manufacturing of armour rod in transmission line typically uses high-strength materials such as aluminum-clad steel, galvanized steel, or stainless steel. After pre-twisting, the multi-strand wires rotate and wrap around the outer layer of the conductor under longitudinal tension, creating a continuous spiral structure. This structure is adaptable to various conductor sizes and types, facilitating on-site winding onto the conductor surface by hand or mechanical equipment.

The spiral winding process for armor rods conductor cables requires selecting appropriate pre-twisted wire specifications based on the conductor diameter to ensure a tight fit and conformity. This spiral wrapping method is crucial for maintaining the uniformity of the outer structure and ensuring a proper fit at the cable joint hardware.
