Power Transmission Line Stringing Equipment
Power transmission line stringing equipment comprises a range of specialized tools and machinery designed to facilitate the installation and tensioning of overhead power lines safely and efficiently. These tools are essential for handling conductors, cables, and hardware during the construction and maintenance of transmission lines.
-
: These devices apply controlled tension to conductors during stringing to prevent sagging or damage. They come in various capacities, such as 9-ton or 8-ton tensioners, suitable for different voltage levels and conductor sizes.
-
: Used to guide conductors and ropes over towers and obstacles, these come in single sheave, double sheave, three sheave, and more configurations. They are typically made from materials like galvanized steel or engineered-grade nylon to ensure durability and smooth operation.
-
: These clamps grip conductors or earth wires securely during stringing operations. Automatic and manual types are available, designed for different conductor types such as ACSR, AAAC, or ACCC.
-
: Pilot wires help in pulling the main conductor cables while preventing twisting during the stringing process. Anti-twisting ropes are often made from galvanized steel strands with specific strand structures for strength and flexibility.
-
: These tools are used for conductor jointing and crimping operations, ensuring secure and reliable electrical connections on the transmission line.
-
: Reel stands with brakes and conductor lifting tools assist in handling large reels of cable and positioning conductors during installation.
-
: Sag scopes and related devices measure and control the sag of conductors to maintain proper clearance and tension.
-
: Portable grounding equipment ensures safety during stringing by preventing electrical hazards.

These tools are designed to handle a wide range of voltages, from low voltage lines up to 1000 kV super high voltage power lines.
