STER-ACCCTM

Sterlite Aluminium Conductor Composite Core (ACCC) conductor consists of a hybrid carbon and glass fiber core which is wrapped with trapezoidal shaped aluminium strands. The high strength structural core carries most of the conductor's mechanical load, while the fully annealed aluminium strands carry all of the conductor's electrical current. ACCC conductor's composite core is much lighter and stronger than conventional or high-strength steel core.

 
Application
 
Aluminium Conductor Composite Core

Sterlite Aluminium Conductor Composite Core (ACCC)

Ideal for Reconductoring

● Increase capacity while improving line clearance and losses.
● Reduce strain on structures increasing life.

Reduced Line Losses in New Lines

● Under equal load conditions reduces line losses by 30%-40% compared to conductors of the same diameter and weight.
● 100% more capacity building towards future demands.

Benefits

● With 28% more annealed aluminium in a trapzoidal configuration the ACCC conductor of the same diameter as ACSR, can double the current (ampacity) rating; Higher operating effciency reduces line losses and associated emissions by more the 35%, resulting in more power delivered and lower power generation costs.
● ACCC conductors use a patented carbon/glass/thermoset resin core that provides height strength and reduces height temperature sag.
● Can re-conductor existing pathway without structural modification and reduce capital expenses on new lines.
● Uses conventional installation methods, tools and mostly conventional hardware. Requires no special tools and limited special training.
● Resists environmental degradation-will not rust, corrode or cause electrolysis with aluminium conductors and components.
