What governing standard and construction define ACCC /TW (Carbon-Composite Core Trapezoidal Aluminum Overhead Conductor)?

ACCC /TW (Carbon-Composite Core Trapezoidal Aluminum Overhead Conductor) is manufactured in accordance with ASTM B987 / IEC 62219 for Up to 500 kV AC service over -40 °C to +180 °C. Its 2-layer construction comprises hybrid carbon / glass-fiber composite core, compact trapezoidal 1350-o aluminum layers.

What is the minimum bending radius and installation temperature for ACCC /TW?

The minimum installed bending radius for ACCC /TW is 25 × OD across its continuous operating temperature range of -40 °C to +180 °C, ensuring mechanical and dielectric stability without conductor or insulation strain.

How are the concentric layers of ACCC /TW arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Hybrid carbon / glass-fiber composite core (Single-piece pultruded carbon-fiber inner core with galvanic glass-fiber outer shell); (02) Compact trapezoidal 1350-O aluminum layers (Interlocking trapezoidal fully annealed 1350-O aluminum wires (+180 °C continuous)).

What factory test certificates are supplied with ACCC /TW?

Every production drum or spool of ACCC /TW undergoes routine conductor DC resistance, dimensional and dielectric/integrity testing per ASTM B987 / IEC 62219, and is delivered with an EN 10204 3.1 factory test certificate.
