AAC Cable vs. ABC Cable: Key Differences, Applications & How to Choose  

AAC Cable (All Aluminum Conductor): This refers specifically to a bare wire. It is a stranded conductor made of pure, unalloyed aluminum (1350 grade, ≥99.7% purity). It has no insulation or jacket. AAC is a single, bare wire used in overhead transmission and distribution lines, typically mounted on insulators.

ABC Cable (Aerial Bundled Cable): This refers to a complete cable system. ABC consists of multiple insulated cores (which can use AAC, AAAC, or ACSR as the conductor material) that are twisted or bundled together. Each core is individually insulated (usually with XLPE or HDPE), making it a self-contained, multi-core cable designed for low-voltage overhead distribution.

Types of Overhead Cable—Aerial Bundled Cable

When planning low-voltage overhead power lines, it is necessary to consider the adjustment and transformation of existing overhead power lines according to the development plan, various types of power consumption indicators and characteristics, and propose a power supply development plan.

Here are the steps to plan:

(1) Electricity Load Survey: The power load is the basis for planning. Multiply the total kilowattage of the electricity load calculated by each unit by the load and the coefficient equal to the actual power kilowatts. Then consider the development of the next five years, and then provide the selection data of the distribution transformer address.

(2) Selection of Transformer Capacity: The transformer should be installed in the load center, and the convenience of management and replacement should be considered.

The capacity of the transformer is expressed in terms of apparent power in kV·A.
