ACCR versus ACSR Customer demand for power grows, renewable generators wait for interconnection, and intermittent resources demand more flexibility from aging infrastructure. Yet dense populations, environmental concerns, permitting requirements, and land scarcity intensify the schedule, budget and regulatory risks of building or rebuilding lines. To solve these challenges, 3M developed Aluminum Conductor Composite Reinforced (3M™ CCR). 3M ACCR is an advanced transmission conductor designed to replace ACSR or ACSS on existing structures at the same tensions and clearances, giving you up to twice the capacity without the risks of a major construction project. Your line is in service fast, within budget, and with minimal environmental impacts. And the available trapwire options may help improve the line’s efficiency.

ALUMINUM CONDUCTOR ADVANTAGES IN OVERHEAD DISTRIBUTION LINE SYSTEM What are the advantages of aluminium conductors for distribution line application?  It is a worldwide practice that when it comes to transmission and distribution line system application, aluminium conductors rank first as the most utilized type of conductor material for electrical applications. ACSR or Aluminum Conductor Steel Reinforced is one of the most popular types of conductor used by electric utilities worldwide. The reason for aluminium’s popularity in electrical lines application can be discussed in many aspects. Seven distinct characteristics are basically known why electrical engineers treat aluminium to be superior when it comes to distribution line application; conductivity, light weight, strength, workability, corrosion resistance, creep, and compatibility with insulation. Aluminum’s conductivity is known to be more than twice compared to that of a copper with the same weight. A pure aluminum conductor

Losses occurs in every transmission line all because of its inherent property of electrical resistance. Electrical lines like ACSR cable possesses resistance which is considered to be a determining factor on knowing the extent of losses it could give to the system. That is why it vital for us to know the internal properties of these conductors for us to better understand its effect to system's loss. Tables shown below are some of the commonly used conductors in an electrical system. Conductor resistance is in per kilometer basis at 60 hz.
