Multi-Roller Pithead Protection Roller To Protect Power Cables And Pulling Ropes

A Multi-Roller Pithead Roller (also called a multi-wheel pithead protection roller) is a cable guiding device used at cable pitheads or duct entries to protect cables and pulling ropes during installation by providing smooth, low-friction guidance around bends or entry points.

Key Features:

• Number of Rollers: Typically 3 rollers arranged to guide cables smoothly.

• Curvature Radius: Commonly available with curvature radii of 450 mm (R450) or 700 mm (R700), helping maintain the cable’s minimum bend radius.

• Maximum Cable Diameter: Models accommodate cables up to 100 mm or 160 mm in diameter.

• Wrap Angle: Around 45°, which helps in guiding the cable around corners or duct entrances.

• Weight: Varies by model, e.g., approximately 7.7 kg for R450 with 100 mm cable capacity, and 14 kg for R700 with 160 mm cable capacity.

• Material: Often constructed from aluminum or steel with nylon or aluminum rollers for durability and smooth operation.

• Applications: Used in power construction, underground cable laying, and other cable installation projects to reduce cable wear and pulling force at pitheads or duct entries.

·Notes :

1.protect the conductor and pulling rope at wellhead bus-bar.

2.leaning against the side of pithead directly while using.

Benefits:

• Protects cables and pulling ropes from abrasion and mechanical damage.

• Reduces pulling tension by providing smooth cable guidance.

• Durable and lightweight for easy handling on-site.

• Suitable for a variety of cable diameters and installation conditions.

Summary:

Multi-Roller Pithead Rollers are essential cable installation tools featuring three rollers with curvature radii of 450 mm or 700 mm, designed to protect cables up to 160 mm diameter at pitheads or duct entrances. They reduce cable damage and pulling effort by ensuring smooth, controlled cable movement around bends during underground cable laying.
