The diameter of the bullwheel on a OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner or puller is a critical design factor, especially for overhead transmission lines. A larger bullwheel diameter offers two main benefits:

1. Reduced Bending Stress: Large diameter wheels ensure that the conductor is not bent at an overly tight radius. This is crucial for high-voltage conductors, particularly OPGW (Optical Ground Wire), which can be permanently damaged by excessive bending stress. The larger the diameter, the gentler the bend.

2. Increased Grip and Efficiency: The larger surface area allows the pulling rope or conductor to be wrapped around the bullwheel more effectively, providing superior grip and torque. This reduces the chance of slippage and ensures a smooth, constant pull, which is essential for maintaining the conductor's sag and tension profile during stringing.

Our bullwheel pullers are designed with large diameters to meet and exceed industry standards, protecting the integrity of your valuable conductors.
