Custom cable reels： Custom Sheet Metal Fabrication in Electrical Power

In the electrical power industry, efficient cable management is critical for safety, organization, and operational efficiency. Custom sheet metal fabrication plays a vital role in manufacturing durable and functional cable reels (also known as cable drums or spools). These components are essential for storing, transporting, and deploying electrical cables in power plants, substations, and industrial facilities.

This blog explores:
✔ Why custom sheet metal cable reels are essential
✔ Design considerations for electrical applications
✔ Material and fabrication techniques
✔ Benefits over standard solutions
✔ Industry-specific applications

Let’s dive into how precision bending, welding, and forming enhance cable reel performance.

1. Importance of Custom Sheet Metal Cable Reels

Cable reels must withstand heavy loads, corrosion, and harsh environments. Standard plastic or wood alternatives often fail under extreme conditions—making sheet metal fabrication the preferred choice.

Key Advantages of Metal Cable Reels:

✅ High load-bearing capacity – Supports heavy-duty power cables effortlessly.
✅ Corrosion resistance – Galvanized steel or aluminum ensures longevity.
✅ Custom sizing – Accommodates unique cable lengths and diameters.
✅ Safety compliance – Meets UL, IEC, and NEC standards for electrical equipment.

2. Design Considerations for Electrical Applications

Designing cable reels requires expertise in structural integrity, ergonomics, and electrical safety. Key factors include:

A. Flange Diameter & Core Design

• Larger flanges (≥24 inches) reduce cable bending stress.
• Reinforced cores prevent deformation under high tension.

B. Material Selection

C. Safety Features

• Locking mechanisms – Prevent accidental unwinding.
• Grounding lugs – Essential for high-voltage applications (IEC 60204 compliance).

3. Fabrication Techniques for Cable Reels

A. Precision Sheet Metal Bending

• Press brake bending ensures consistent flange curvature (±0.5mm tolerance).
• Roll forming produces smooth edges to protect cables.
