Aerial bundled cable
Aerial bundled cables (also aerial bundled conductors or simply ABC) are overhead power lines using several insulated phase conductors bundled tightly together, usually with a bare neutral conductor. This contrasts with the traditional practice of using uninsulated conductors separated by air gaps. This variation of bundled conductors utilizes the same principles as overhead power lines, except that they are closer together to the point of touching but each conductor is surrounded by an insulating layer (except for the neutral line).Applications include:
- LOW VOLTAGE ABC
Our Low Voltage ABC are manufactured in accordance with a range of national standards – British standard BS7870, French standard NF C33 209, Australasian standard AS/NZS 3560 Part 1, and IEC standards IEC 60502-1, TNB Specification, and HD 626 S1. They have a voltage rating of 0.6/1kV. With the insulation it also meets Class II according to IEC 61140 in protecting against electric shock. Aerial Bundle Cables have an operating temperature range of -40oC to +80oC and can be installed in temperatures as low as -20oC. These ABC are unscreened and without an additional outer sheath.
The LV ABC have both phase conductors and a neutral conductor – both Class 2 stranded Aluminium – with core identification being provided by ribs on the insulation: Phases by longitudinal ribs (I, II, III), Neutral core by longitudinal ribs (≤ 50 mm2 min.12 ribs; ≥ 50 mm2 min.16 ribs).
- MEDIUM VOLTAGE ABC
We also supply Medium Voltage Aerial Bundle Cables, in voltages of 6.35/11kV, 12.7/22kV and 19/33kV. Manufactured in accordance with IEC 60502-2, we also have variants made specifically to Australian and New Zealand standards AS/NZS 3599 Part 1. In addition to the XLPE insulation, these higher voltage cables are sheathed with High Density Polyethylene (HDPE). They are available with and without additional screening, in light and heavy duty copper wire or tape, depending on the installation parameters and requirements.

Determining the suitability of Aerial Bundle Cables for your overhead line application and the accompanying cable size calculation can be supported by our technical team. They will consider the application, the installation environment, and the regulations of the project country, and will guide your decision to specify Aerial bundle cables or other OHL products along with accompanying cable accessories.
