Polyurethane Drum Cable: Durable and Flexible Power Solution for Reeling Applications

In industrial automation, construction, and machinery operations, reliable reeling cables are essential for safe and efficient power transmission. Polyurethane drum cables (PU reel cables) are specially designed to meet the demands of repeated flexing, mechanical stress, and harsh environments.

These cables combine high flexibility, abrasion resistance, and chemical durability, making them ideal for use on cable reels, energy chains, and mobile equipment.

1. Product Overview

Polyurethane (PU) drum cables are engineered for applications where cables are constantly wound and unwound, such as:

• Cable reels and drums

• Crane and hoist systems

• Automated guided vehicles (AGVs)

• Material handling and conveyor systems

Key Features:

• High elasticity and flexibility

• Long service life under dynamic conditions

• Resistant to oil, chemicals, abrasion, and impact

• Suitable for indoor and outdoor industrial environments

2. Construction and Materials

1. Conductor

• High-purity stranded copper for maximum flexibility

• Ensures stable electrical conductivity under repeated bending

2. Insulation

• Made of high-grade polyurethane (PU)

• Provides excellent mechanical and chemical resistance

• Maintains flexibility in a wide temperature range (-40°C to +90°C typical)

3. Sheath

• Thick polyurethane outer layer protects against:

• Abrasion and cuts

• Oil, grease, and chemical exposure

• UV exposure in outdoor applications

3. Advantages of PU Drum Cables
