What is a key practice when pulling conductors to avoid damaging insulation?

• A. Pull quickly with jerks.
• B. Use lubricant, avoid sharp bends, and pull steadily within the recommended tension.
• C. Apply heat to soften insulation.
• D. Use pliers to grip the conductor.

Answer: (B)

Pulling conductors without damaging insulation comes down to controlling friction and tension. Using lubricant to reduce friction, avoiding sharp bends that can kink or pinch insulation, and pulling steadily within the recommended tension all work together to distribute the force evenly along the conductor and preserve insulation integrity. Lubricant lowers resistance as the cable slides, reducing heat and wear. A steady, measured pull prevents sudden shocks that can tear or deform insulation, unlike jerky pulls that can cause damage. Applying heat to soften insulation can weaken it or cause degradation, and gripping with pliers can crush or nick the insulation. So the combination of lubrication, careful routing, and controlled tension is the right approach.
