Aerial Bunch Cables (ABC)

Aerial Bunch Cables(ABC):Enhance safety and efficiency

ATC make Aerial Bunch Cables as per IS 14255:1995, which pertains to Aerial Bunched Cables (ABC) for working voltages up to and including 1100 volts:

Scope:

  • This standard outlines the requirements for Polyethylene/crosslinked polyethylene insulated cables with aluminium conductors.
  • These cables are designed for use as overhead distribution feeders.

Construction and Features:

  • Insulation: The cables have polyethylene (PE) or crosslinked polyethylene (XLPE) insulation UV rays protected.
  • Conductors: They feature aluminium conductors.
  • Twisting Design: The insulated conductors (usually 3 or 4 in number) are twisted around a  high-strength aluminium alloy bearer wire.
  • Earth-Cum-Neutral Wire: The bearer wire serves as both the earth and neutral wire and with street light conductor (optional).
  • Safety and Fault Minimization: The ABC system ensures safety, practically eliminates low-tension (LT) faults, minimizes supply interruptions, reduce transmission losses and extends the life of transformers.

Advantages of Aerial Bunched Cables (ABC):

  • Safety: The phase conductors are not under tension, making it a safe system.
  • <Fault Reduction: LT faults are significantly reduced compared to bare conductors.
  • Tree Clearance: The problem of tree clearance is minimized.
  • Practical Elimination of LT Faults: Interruptions of supply are minimized due to the system’s design.
  • Power saver: reduced the transmission losses and theft proof cables.

Reduction in Power Losses:

  • The bundled configuration of ABC reduces power losses, enhancing the overall efficiency of the power distribution system.
  • Closer proximity of conductors minimizes electromagnetic fields and reduces energy losses through induction and radiation

Resistance to Environmental Factors:

  • ABC is designed to withstand UV radiation, moisture, temperature variations, and chemical exposure.
  • The insulation materials used provide excellent resistance to weather conditions, preventing degradation and ensuring long-term performance¹ .

Improved Reliability and Performance:

  • The bundled configuration enhances the reliability of power distribution networks.
  • ABC is less prone to damage from tree branches, birds, or external disturbances, reducing downtime and improving overall network performance¹ .

Scope

  • The bundled configuration enhances the reliability of power distribution networks.
  • ABC is less prone to damage from tree branches, birds, or external disturbances, reducing downtime and improving overall network performance¹ .

Cost-effectiveness:

  • ABC eliminates the need for separate insulators, reducing installation and maintenance costs.
  • Fewer supporting structures (poles and towers) result in reduced infrastructure expenses¹ .

Easy Installation and Maintenance:

  • ABC is relatively easy to install compared to bare conductor systems.
  • The bundled configuration simplifies installation, reducing labor costs.
  • Minimal maintenance is required due to its durable construction and resistance to environmental factors¹ .

Compatibility with Existing Infrastructure:

  • ABC seamlessly integrates into existing power distribution infrastructure.

It is compatible with various pole-mounted or overhead line systems, allowing for upgrades or replacements without significant modifications¹

Application:

  • ABCs are commonly used for  overhead distribution in various settings.

Standard Details:

  • Title: Aerial Bunched Cables for working voltages up to and including 1100 Volts IS:14255/1995.

In conclusion, Aerial Bunch Cables are a reliable and cost-effective alternative for overhead power lines. They withstand harsh weather conditions and provide better protection against electrical faults and short circuits ². Whether in rural areas, urban settings, or industrial zones, ABC ensures efficient and safe electricity distribution.
