Introduction to flexible cables (dragging cables)

ABC cable, whose full name is Aerial Bundled Cable, is an overhead power cable that bundles multiple insulated conductors together in phase sequence. It is primarily used in low-voltage distribution systems with rated voltages of 0.6/1 kV and below.

Compared to traditional overhead bare conductors, it does not simply bundle several wires together. Instead, through structural design, it achieves significant improvements in safety, line loss rate, and construction efficiency, and is regarded as an important alternative to traditional bare conductors.

Structure and characteristics of ABC Cable (Aerial Bundled Cable)

Depending on the conductor material, insulation material, and structural shape, ABC cables are available in several types. The common classifications are summarized below for reference during selection:

Classification	Type	Description
By Structure	Square Type (BS1), Star Type (BS2), Flat Type (BS3)	The Square Type is most common, with four conductors arranged in a square formation for stable structure.
By Conductor Material	Aluminum Core, Copper Core	Aluminum core is most commonly used due to lower cost; copper core offers better conductivity but at a higher cost.
By Insulation Material	PVC, PE, XLPE	XLPE (cross-linked polyethylene) offers the best performance, with higher temperature rating and longer service life.
Common Model	BS-JKLYJ	This common model stands for Bundle Structure (BS) - Aerial (JK) - Aluminum Core (L) - XLPE Insulation (YJ).

Core advantages of ABC cable

ABC cable is widely used both domestically and internationally, primarily due to its outstanding advantages in the following four aspects:
Significantly reduce line loss: Due to the tight "bundling" of conductors, the reactance (a type of resistance) of the line is effectively reduced. This results in reduced voltage loss and improved transmission efficiency. Actual data shows that for low-voltage lines using ABC cables, the line loss rate can be reduced to 5%-10%, while the line loss rate for traditional bare conductors is typically between 15%-20%.
Significantly enhanced safety: This is the most intuitive advantage of ABC cable.
Electric Shock Prevention: The fully insulated design completely prevents electric shock accidents caused by humans or animals accidentally touching bare wires.
Short-circuit prevention: It effectively prevents short circuits caused by contact between two-phase lines due to factors such as tree branches, birds, and strong winds, greatly enhancing the reliability of power supply.
Anti-electricity theft: The insulating layer increases the difficulty of electricity theft.
Convenient construction and cost savings: One laying can complete the erection of multi-phase lines, eliminating the need to separately install cross arms and insulators for each phase line as with bare conductors. This not only saves about 30% of construction time but also significantly reduces hardware costs. In densely populated areas, it is even possible to lay directly along the walls without erecting poles.
Comprehensive economic benefits: Although the material cost of ABC cable is slightly higher than that of bare conductors, due to the savings in supporting hardware, towers, and construction costs, its overall cost is on par with or even lower than that of bare conductors. At the same time, its maintenance costs in the later stage are also much lower than those of bare conductors.
