Product Description
APAR’s Aluminium Conductor Composite Core (ACCC®) is an advanced High Temperature Low Sag (HTLS) conductor designed to deliver superior electrical performance, higher ampacity, and significantly lower sag compared to conventional ACSR conductors. Utilizing a lightweight hybrid carbon and glass fiber composite core, ACCC® conductors offer exceptional strength-to-weight ratio, improved conductivity, and enhanced corrosion resistance.
Designed for transmission line uprating and grid modernization projects, ACCC® conductors enable utilities to increase power transfer capacity while utilizing existing transmission infrastructure, making them an ideal solution for growing energy demand and renewable energy integration. APAR also offers ACCC® AZR conductors for snow-prone areas.

Standards & Quality
APAR’s ACCC® conductors are manufactured and tested in accordance with internationally recognized standards and customer specifications to ensure superior electrical and mechanical performance.
Each conductor is manufactured through very stringent quality standards, with rigorous testing at every stage including type testing and validation.
Construction & Material
ACCC® conductors consist of fully annealed trapezoidal-shaped aluminium wires concentrically stranded over a hybrid carbon and glass fiber composite core.
The composite core provides exceptionally high strength with very low thermal expansion characteristics, significantly reducing conductor sag under elevated operating temperatures.
The outer layers comprise 1350-O tempered aluminium wires with superior conductivity, maximizing aluminium content within the conductor diameter and resulting in superior electrical conductivity and lower transmission losses compared to conventional conductors.
This advanced construction enables increased power transfer capacity while maintaining excellent mechanical and thermal performance.
