If you're searching for "What equipment is needed for ABC cable," you're likely a purchaser, engineer, or entrepreneur in the cable industry preparing to enter the field of aerial bundled cable production.

ABC cable (Aerial Bundled Cable) is an aerial transmission product widely used in urban power distribution networks and rural power grid upgrades, and its demand has been steadily increasing in recent years. However, many people are unfamiliar with its production equipment and installation tools.

Today, as a Hebei Zhongdong Cable Manufacturer (a national high-tech enterprise and a specialized and innovative "little giant" enterprise focusing on the R&D and production of power cables), I will provide a comprehensive breakdown: from the manufacturing equipment on the production line to the installation tools on the construction site, what equipment is actually needed for ABC cable production?

I. Quickly understand: What is ABC cable?

ABC cable, short for Aerial Bundled Cable, is an aerial cable system in which multiple insulated conductors (usually phase wires and a neutral wire) are bundled together using a specific twisting method. Its key feature is the replacement of the traditional "distributed" layout of bare overhead conductors with a "bundled" layout, significantly reducing line failure rates and the risk of electric shock.

ABC cables commonly operate at voltage levels of 0.6/1kV (low voltage) and medium voltages of 10kV and 35kV, and are widely used in urban power distribution networks, rural power grid upgrades, street lighting, and other applications.

Our Middle East cable production license explicitly covers "overhead insulated cables with voltage ≤10kV and cross-sectional area ≤400mm²", demonstrating mature manufacturing capabilities in this field.

II. Manufacturing End: What Production Equipment is Required for ABC Cables?

The production process for ABC cables mainly includes: wire drawing → stranding/bundling → insulation extrusion → cabling and stranding. The following is a list of core equipment:

1. Wire Drawing Machine

This is the first step in cable production. The wire drawing machine stretches copper or aluminum rods to the required precise diameter using a die.

For ABC cables, since overhead cables often use aluminum or aluminum alloy conductors, a dedicated aluminum wire drawing machine is required. 1. **Strict Control of Elongation and Resistivity during the Wire Drawing Process:** The conductivity of overhead cables directly affects line loss and transmission efficiency.

2. **Stranding Machine/Bundling Machine:** After drawing, the individual filaments need to be stranded into conductors. ABC cables typically use a variant structure of multi-strand round aluminum wire or steel-cored aluminum stranded wire, requiring tubular or frame-type stranding machines to achieve concentric stranding.

Key parameters for this type of equipment include stranding pitch and tension control. Uneven pitch can lead to an uneven cable appearance and even affect electrical performance.

3. **Insulation Extrusion Line:** After conductor stranding, the insulation layer needs to be extruded and coated. ABC cable insulation materials are typically cross-linked polyethylene (XLPE) or weather-resistant polyethylene, requiring good resistance to UV radiation, aging, and environmental stress cracking.

This production line typically includes: a pay-off stand → a preheating device → an extruder → a cooling water tank → a spark tester → a take-up device.

It's worth mentioning that our Middle East cables strictly adhere to national standards GB/T 12527 (1kV overhead insulated cables) and GB/T 14049 (10kV overhead insulated cables), with rigorous quality control at every stage, from insulation materials to extrusion processes.

4. Cabling Machine / Cabling Line

This is the core process that distinguishes ABC cables from ordinary insulated cables. ABC cables are not single insulated cores, but rather multiple insulated cores twisted together to form a bundle.

Depending on the number of conductors, ABC cables can be 2-core, 3-core, or 4-core (e.g., a 3+1 structure, with three phase wires plus one carrying wire with a neutral wire or steel strand).

During cabling, a bow-forming cable machine or a cage-type cable machine is used to twist the insulated cores together according to a specified pitch. For ABC cables with a carrying wire carrying core, the carrying core must be released simultaneously while maintaining uniform tension.

5. Other Auxiliary Testing Equipment

Reputable cable manufacturers must also be equipped with a full set of testing equipment: partial discharge testing equipment (for 10kV and above ABC cables), insulation resistance tester, conductor DC resistance tester, tensile testing machine, etc.

This is why clients who truly export and undertake large-scale projects (such as State Grid and China Power Construction, who have long cooperated with us on Middle East cables) choose qualified manufacturers—every reel of cable undergoes rigorous multi-stage testing before leaving the factory.

III. Installation and Construction End: What Equipment and Tools are Required for ABC Cable Installation?

Once the equipment is built, how do you install it on the utility pole? Installing ABC cables is not as simple as installing ordinary electrical wires; it requires specialized tools.

1. Pay-off Stand & Tensioner

ABC cables must not be twisted or knotted during the pay-off process, otherwise the internal insulation will be damaged. Therefore, an adjustable tension pay-off stand or tension pay-off cart is needed to ensure that the cable is released at a uniform speed and tension.

2. Wedge Tool – An Essential for Safe Operation

This is a very practical but easily overlooked tool. ABC cables are multi-core bundled cables, requiring the temporary separation of several cores during installation for wiring or branching.

An insulated ABC wedge tool is specifically designed to safely separate the cores of bundled cables, facilitating installation and maintenance. This tool typically conforms to IEC 60900 standards and can be operated under energized conditions in 1000V AC and 1500V DC systems, ensuring the safety of construction personnel.

3. Tension & Suspension Clamps

ABC cables cannot be directly tied to poles or crossarms; they must be secured using specialized clamps. Relevant standards (such as EN 50483-3) specifically specify the testing requirements for tension and suspension clamps for ABC cables.

Tension clamps: Used at line terminals or corners to withstand cable tension.

Suspension clamps: Used on straight-line poles to suspend the cable from insulators.

These clamps are typically installed on the neutral or carrier core of ABC cables, and their design must consider electrochemical corrosion resistance and gripping force requirements.

4. Bi-Metal ABC Lug

The conductors of ABC cables are typically aluminum, but the terminals of transformers or switchgear are copper. Direct copper-aluminum connections can cause electrochemical corrosion.

Therefore, a bi-metallic lug is needed—its terminal portion is copper, and the cable crimping portion is aluminum, fused together using a friction welding process and pre-applied with conductive paste.

During installation, a hydraulic crimping tool (such as a 13-ton crimping tool) is required to press the terminal onto the cable conductor.

5. Hydraulic Crimping Tool
The installation of the above bi-metallic terminals must rely on a hydraulic crimping tool. Common types include manual hydraulic crimping tools (portable, suitable for high-altitude operations) and electric hydraulic pumps + crimping tools (suitable for large cross-section cables).

Different cross-sections (e.g., 25mm², 35mm², 95mm², 150mm²) correspond to different mold specifications and crimping times.
