Copper, Aluminum and Granules: Essential Raw Materials for Modern Cable Manufacturing

Cable production plays a critical role in many fields, including energy transmission, communication infrastructure, and industrial automation. At the core of this sector lies one key factor: the right choice of raw materials. Among these, copper, aluminum, and granules are indispensable components of modern cable manufacturing. In this article, we explore the features, applications, and industry importance of these three essential materials.

1. Copper – Maximum Conductivity and Reliable Performance

Copper is the most preferred metal in cable manufacturing thanks to its unmatched electrical conductivity. Electrolytic copper with over 99% purity is the standard for energy cables, low-voltage communication cables, and various industrial applications.

Advantages of Copper

• High electrical conductivity (the highest after silver)

• Long lifespan with excellent corrosion resistance

• Flexible and easy-to-process structure

• Safe performance at high temperatures

Typical Applications

• Power transmission cables

• Installation cables

• Communication and signal cables

• Grounding systems

• Automotive and electronics manufacturing

With its exceptional conductivity, copper remains the top choice for energy-intensive projects.

2. Aluminum – Lightweight, Cost-Effective, and Efficient

Although not as conductive as copper, aluminum has gained significant importance in the cable industry due to its lightweight structure and cost advantages. It is an ideal alternative for building economical power infrastructure solutions.

Advantages of Aluminum

• Significantly lighter than copper

• Cost-effective material

• Good corrosion resistance

• Easier installation in long-distance cable applications

Typical Applications

• Power transmission lines

• XLPE aluminum cables

• Cable support systems in large facilities

• Industrial infrastructure projects

Aluminum is widely used in large-scale projects where performance and cost balance is essential.

3.The Importance of PVC Granules in Cable Manufacturing

PVC granules are one of the most commonly used raw materials in cable insulation and outer sheath production. With their durability, cost-effectiveness, and easy processability, PVC granules have become a standard material in the cable industry.

Advantages of PVC Granules

• High insulation: Ensures electrical safety.

• Flexible and durable: Resistant to bending, impact, and abrasion.

• Various formulations: Flame-retardant, UV-resistant, soft/hard options.

• Economic solution: A cost-effective and widely used raw material.

Applications

PVC granules are widely used in energy cables, low-voltage cables, control cables, and communication cables.

In conclusion, PVC granules provide safe, durable, and economical solutions, making them an essential raw material in modern cable manufacturing.
