What is an ACFR Conductor?

আ ACFR কন্ডাক্টর is a high-performance overhead transmission conductor that uses a composite core made of fiber-reinforced materials instead of traditional steel. The outer layer consists of aluminum strands, while the inner core is typically composed of carbon fiber or glass fiber composites.

This innovative design offers significant improvements over conventional conductors, particularly in terms of:

• Weight reduction
• Tensile strength
• Thermal performance
• Sag resistance

ফলে, ACFR conductor is increasingly used in high-capacity transmission lines, especially in projects requiring long spans or high-temperature operation.

Structure of ACFR Conductor

The ACFR conductor consists of two main components:

1. Aluminum Strands

The outer layer is made of high-conductivity aluminum, responsible for carrying electrical current. These strands are typically designed to meet 63% IACS conductivity, দক্ষ পাওয়ার ট্রান্সমিশন নিশ্চিত করা.

2. Composite Core

The core replaces traditional steel with advanced composite materials. Key characteristics include:

• উচ্চ প্রসার্য শক্তি
• Low thermal expansion
• Lightweight structure
• জারা প্রতিরোধের

This combination enables ACFR conductor to outperform conventional ACSR conductors in demanding environments.
