The equipment used for electricity transmission and construction is highly specialized and can be categorized into three primary areas, each with a distinct function in building and maintaining the power grid.

1. Overhead transmission line (OHTL) Equipment: This category includes the heavy machinery and tools used to build and maintain the massive overhead power lines that carry electricity over long distances. The key equipment in this category is our wire cable conductor tension stringing equipment, which includes:

   • Hydraulic Pullers: Used to pull the conductor from a drum to the next tower.

   • Hydraulic OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners: Used to apply back tension to the conductor, ensuring it is installed with the correct sag and tension to prevent damage.

   • Anti-twisting Steel Ropes, Swivels, and Connectors: Critical accessories for the stringing process.

2. underground cable laying Equipment: As a growing alternative, underground power lines require a different set of tools and machinery to install cables safely beneath the ground. This includes specialized equipment like:

   • Cable Pulling Winches: Used for pulling heavy cables through trenches or ducts.

   • cable rollers and Sheaves: To guide cables during the laying process.

   • Cable Stand Jacks: Used to support cable drums and facilitate unwinding.

3. Substation and General Electrical Construction Tools: In addition to the large machinery, a wide array of tools is required for the construction, maintenance, and repair of substations and other electrical infrastructure. These include safety equipment, grounding tools, cable cutters, crimpers, and a variety of specialized hand tools.

As a prominent manufacturer and exporter, Ningbo Changshi is proud to offer a comprehensive, one-stop supply of all these categories of equipment.
