The Aerial Bundled Cable (ABC) compliant with IEC and British Standards is a revolutionary overhead power distribution solution designed for safe and efficient electricity transmission in densely populated areas.
This cable system consists of multiple insulated conductors bound together with a durable outer binding, creating a compact, weather-resistant assembly that minimizes the risk of accidental contact and short circuits.
The conductors are typically made of high-purity aluminum or copper, depending on application requirements, and are insulated with:
Cross-linked polyethylene (XLPE) – for superior electrical and mechanical properties
Polyethylene (PE) – for cost-effective performance
| Standard | Description |
|---|---|
| IEC 60228 | Conductors of insulated cables |
| BS 7870 | Aerial bundled cables for overhead distribution |
This ensures compatibility with global power grids while adhering to strict safety and performance criteria.

Q: Can the ABC system be used for both low- and high-voltage applications?
A: Yes. It is available in voltage classes ranging from 1kV to 36kV, suitable for distribution networks in various settings.
Q: How does the bundling affect the cable's thermal performance?
A: The design includes thermal management considerations, and the insulation materials have high heat resistance to ensure safe operation within rated current limits.
Q: Is the binding material UV-resistant?
A: Yes. The binding is made from UV-stabilized polymers that prevent degradation from prolonged sunlight exposure, ensuring long-term structural integrity.
Q: Does the ABC system require special installation equipment?
A: Standard overhead line installation tools can be used, though training on bundling techniques is recommended to ensure proper conductor spacing and tensioning.
