Below are some of the most common questions and key terms used in professional certification exams and training materials for overhead conductor and underground cable installation.

Q1: What is "tension stringing" and why is it the preferred method for overhead conductor installation? ⚡️

A: Tension stringing is a method of installing overhead conductors by keeping them under a constant, controlled tension. This prevents the conductor from ever touching the ground, protecting its surface from damage and ensuring a safe working environment, especially when crossing roads, existing power lines, or other obstacles. This process requires a synchronized hydraulic puller and OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner.

Q2: What is the primary function of a "hydraulic OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner" in the stringing process?

A: The hydraulic tensioner's primary function is to apply back tension to the conductor reel during the pull. This ensures the conductor is kept elevated and taut, preventing it from sagging and coming into contact with the ground or other objects, which could cause damage.

Q3: What is the purpose of a "stringing block"?

A: A stringing block (also known as a sheave or traveler) is a pulley system attached to a tower or pole arm. It guides the conductor smoothly along the route, reducing friction and ensuring the conductor's outer surface is not damaged during the pulling process. They are essential for a successful tension stringing operation.

Q4: Why is it crucial to use a "swivel" when pulling a conductor?
