Various types of overhead cables

AAC, AAAC, and ACSR Bare Conductors are used as overhead power lines, transmission lines, and distribution lines. An aluminum bare conductor is a wire without an insulating layer on the outside of the conductor. Different conductor materials are suitable for different span lengths and the ability to withstand breaking strength. All aluminum conductors consist of one or more bundles of aluminum wire, depending on the specific application environment of the product. Due to the natural corrosion resistance of the all-aluminum structure, it is also popular in coastal areas.

Description of Bare Conductor

Overhead lines are high voltage transmission line bare conductors above the ground level, supported by pylons and poles. ZMS aluminum alloy conductor overhead power lines have a series of advantages such as strong load and overload capacity, good heat resistance, large transmission capacity, and high tensile strength. At the same time, it can also greatly reduce the investment in line construction, effectively improve the urban environment, and is widely used in urban and rural power grid reconstruction.

AAC — All Aluminum Conductor

AAC Conductor is a refined aluminium-stranded conductor with a minimum metal purity of 99.7%. It is mainly used in urban areas with short distances and close supports. Its characteristics are good corrosion resistance and can be used near the coast. The AAC (all aluminum conductor) wire is the most economical bare overhead conductor due to its lighter weight.

Hard-drawn aluminum conductor as per EN 60889 Type AL1 according to BS 215.

AAAC — All Aluminum Alloy Conductor

Compared with AAC and ACSR, AAAC conductor is mainly used as bare overhead transmission cables and as primary and secondary distribution cables.  It has better strength and weight, better electrical properties, better vertical tensile properties, and better corrosion resistance. These characteristics make AAAC widely recognized and loved by more people in power distribution and medium and high voltage transmission lines.

AAAC conductor is made of from aluminum-magnesium-silicon alloy of high electrical conductivity (min 53% IACS) containing magnesium (0.6-0.9%) & silicon (0.5-0.9%) to give it better mechanical properties after treatment. AAAC conductors are made out of aluminum alloy 6201.
Standards / Testing Specifications
IEC 61089, BS EN 50182, BS 215 part2, ASTM B232, DIN 48204, GB/T 1179-2008, and customer’s required standards.

ACSR — Aluminum Conductor Steel Reinforced

ACSR is a high-voltage transmission cable used in grid applications.  ACSR has a wide range of applications. Suitable for transmission lines of various voltage levels. Can also be laid in rivers, canyons, and places with special geographical features. ACSR bare conductors have been widely used in power transmission lines with various voltage levels because they have such good characteristics as structure, convenient installation and maintenance, and low-cost large transmission capacity. They are also suitable for laying across rivers valleys and places where special geographical features exist.

The structure of ACSR is simple. It consists of a solid or stranded steel core surrounded by strands of aluminum. Aluminum 1350-H-19 wires, concentrically stranded on a steel core. The core wire for ACSR is available with class A, B, or C galvanizing.
