ACCC/TW driver

The ACCC/TW driver (Aluminum Conductor Composite Core – Trapezoidal Wire) is a new generation HTLS cable, Designed to meet growing performance needs of electricity transport networks. It is distinguished by a light and resistant composite soul, Replacing the traditional steel heart, as well as by trapezoidal aluminum threads (TW) which increase the density of the driver's metal without weighing down the cable.

Used in existing line strengthening projects, urban modernization or energy transport over long distances, The ACCC/TW driver increases capacity without changing pylons. It offers a higher current transport capacity, a significant reduction in energy losses, as well as increased resistance to the thermal arrow.

Characteristics of the ACCC/TW driver

High current capacity & increased efficiency
Compared to traditional ACSR type drivers, The ACCC/TW driver can carry about twice as much current. Its electrical resistance is reduced by 25 40%, which makes it possible to considerably reduce online losses, energy consumption and CO₂ emissions.

Low thermal arrow & Excellent stability at high temperature
Thanks to its composite soul in carbon and glass fiber, The driver has a very low thermal dilation coefficient. Even at temperatures above 80 ° C, The increase in the arrow remains negligible, guaranteeing the mechanical stability of long races.

High mechanical resistance & Excellent corrosion resistance
The soul in carbon/glass fiber reaches resistance to traction of 2 150 has 2 400 MPa, or about 1,7 has 1,9 times that of a steel soul, while being insensitive to corrosion.

Compact structure
Design with trapezoidal aluminum threads increases the transverse aluminum section of 10 at 30% with equal diameter, which significantly improves conductivity.

Excellent wind and frosty outfit
Its light structure and its composite soul resistant to fatigue make it possible to limit the arrow even under the loads of wind or ice, thus reducing maintenance needs.

Long -term profitability
Although the initial cost is higher (2,5 has 3 times that of ACSR), It is often useless to strengthen or enhance existing pylons. This allows substantial savings on installation costs, long -term maintenance and energy losses.
