Aluminum Conductor Composite Reinforced (ACCR)

Aluminum Conductor Composite Reinforced (ACCR) is a rather new comer to towerline power transmission technology. ACCR can deliver 2 to 3 times the capacity without the risks and delays of major construction projects. On time, in budget, back to service – with proven reliability. Aluminum Conductor Composite Reinforced (ACCR) is overhead transmission conductor like ACSR and ACSS, with higher ampere capacity with less thermal expansion (sag). ACCR can carry two or more times the current of a standard conductor of comparable diameter. It has less weight and sag, but the same strength and can be installed to meet your tension and clearance requirements. This allows you to maximize the capacity of your transmission upgrade using existing structures and rights of way. Compared to a rebuild project, you can get your upgrade done faster and with fewer permitting requirements. ACCR can be used any place standard ACSR conductor. ACCR's core is aluminum-based, rather than steel, it is more conductive than steel core conductors, resulting in lower losses under the same operating conditions. In addition, 3M ACCR comes in a trapezoidal wire design that can improve conductivity up to 28% compared to the same size, round wire ACSR. ACCR Conductors cost around 4 times of the standard conductors. See how easy ACCR is to install by viewing the Installation videos.
