  1How to select Aerial bundled cable?

First, to buy Aerial bundled cable, you must recognize the regular brand, meet the relevant standards, and choose products with quality certification (such as CCC certification) and factory certificate of conformity. Must go to the regular store or supplier agent to buy wire and cable products.

Second, the wire material is divided into copper and aluminum, aluminum wire is easy to oxidation and corrosion. The joint part is easy to catch fire, the incidence of fire is dozens of times the copper wire, so the state named the use of copper conductors in new homes. High-quality copper wire, it’s a copper core selection of high purity of positive red-purple copper, bright surface, slightly soft, poor quality core easy to oxidation, the surface dark.

In addition third, the quality of insulation, poor quality wire using insulation materials are recycled plastic, dark color, loose texture, uneven thickness, poor insulation capacity, ignition with a lighter is easy to aging or breakdown voltage. Qualified insulation material is bright, uniform thickness, ignition does not catch fire, etc.



2what is Aerial bundled cable

ABC Cable, also known as Aerial Bundled Cable, is a type of electrical cable used to distribute power at a voltage level of up to V. This cable consists of numerous insulated conductors, bundled and wrapped together tightly. The main function of Aerial bundled cable is to transfer electrical power from the substation to the end-user. The use of insulation is the main difference between ABC cables and bare conventional transmission cables. it is an essential component in the power distribution process, ensuring that electricity is delivered safely and efficiently to its intended recipients.

Aerial bundled cable can be used to replace bare conductor cables in overhead distribution lines. It is ideal for use in urban areas with congested power distribution and narrow lanes. We can provide you the best aerial bundled cable.

These cables are typically suspended overhead using electrical poles, allowing for easy access to power distribution in a wide range of settings, including residential, commercial, and industrial environments.

3 Aerial bundled cable phase identification

The conductors used for all the cores are of stranded hard drawn aluminium which are compacted, and are available in sizes ranging from 25, 35, 50, 70, 95 or 150 mm2.

Aerial bundled cable is composed of several insulated conductors bundled together. The insulated conductors must be readily identifiable, and there is a special need to distinguish between the phase and neutral conductors. The phase conductors are identified by prominent longitudinal ribs on the core insulation, one, two or three ribs to distinguish between the three phases.

4 Construction of aerial bundled cable

Aerial bundled cable is made up of phase conductor and neutral conductor and insulation. The conductors are typically made of aluminum. The insulation is made of PE or XLPE and is designed to withstand voltage, temperature, and environmental conditions. The bundle of conductors is suspended from poles or towers using messengers and clamps. Aerial bundled cable also called ABC cable, the cable consist of three major components:

     1 phase conductor
          These are aluminum conductor insulated with XLPE or PE. These may be of single, two, or three phase as per the requirement of the circuit.

     2 Neutral conductor(messenger)
          Messenger of the cable is made from aluminum alloy. This is a single conductor which may or may not be insulated. All the cores of the cables are twisted around it, it bears the weight of the complete cable.

     3 Street lighting conductor
     This is an optional object depending upon the circuit requirement. Street lighting conductor of the cable consist of aluminum conductor insulated with XLPE or PE.

Supplementary Note size of aerial bundled cable
