Overhead Cable Comparison Guide by hnbfpower for Reliable Power Lines

Overhead cables are essential for modern power distribution systems. They transmit electricity efficiently across cities, rural areas, and industrial zones. Choosing the right overhead cable can affect safety, cost, and performance. In this guide, hnbfpower compares different types of overhead cables, their specifications, and advantages, to help you make the best decision for your power projects.
1. Types of Overhead Cables
Overhead cables come in several forms depending on structure, material, and usage.
A. ACSR (Aluminum Conductor Steel Reinforced)
-
Structure: Aluminum strands around a steel core
-
Feature: High tensile strength, ideal for long spans
-
Use: Transmission lines and high-voltage power networks
B. AAAC (All Aluminum Alloy Conductor)
-
Structure: Made from aluminum-magnesium-silicon alloy
-
Feature: Better corrosion resistance than ACSR
-
Use: Coastal or industrial regions with corrosive environments
C. AAC (All Aluminum Conductor)
-
Structure: Pure aluminum strands
-
Feature: Lightweight, high conductivity
-
Use: Short-distance low and medium-voltage lines
2. Technical Comparison
Property | ACSR | AAAC | AAC |
---|---|---|---|
Material | Aluminum + Steel | Aluminum Alloy | Aluminum |
Strength | Very High | Medium | Low |
Conductivity | Moderate | High | Very High |
Corrosion Resistance | Moderate | Excellent | Moderate |
Weight | Heavier | Medium | Light |
Applications | Long spans | Coastal areas | Urban networks |
hnbfpower provides each of these types, designed to meet specific environmental and electrical needs.
3. Key Specifications to Consider
When selecting an overhead cable, it’s important to evaluate:
-
Conductor Size: Determines current-carrying capacity
-
Voltage Rating: Choose based on network level (low, medium, high)
-
Temperature Rating: Higher ratings mean better heat tolerance
-
Mechanical Strength: Important for long-span installations
-
Corrosion Resistance: Vital in coastal or polluted regions
hnbfpower cables are designed and tested according to international standards to ensure durability, conductivity, and mechanical strength.
