Introduction
ACCM (Aluminium Conductor Composite Multistrand) is the most innovative bare conductor for overhead power lines in the world because it includes all the advantages obtainable from a HTLS conductor.
ACCM has succeeded innumerable type tests, even combined with the appropriate compression clamps and aroused the interest of many TSO (Transmission System Operator) for the use of this technology in the most challenging lines, allowing De Angeli Prodotti to obtain important contracts for thousands of km.
Engineering
The strength of ACCM lies in its core made up of several composite elements in thermo-resistant carbon fiber stranded together.
This core is protected by a tape and an extruded aluminum tube that makes it resistant to the external agents.
The conductive part is composed of several layers of wires of various geometries in Thermal Aluminium Alloy (Al-Zr).
De Angeli Prodotti can support a correct execution of all installation activities with training and supervision, thanks to its know-how and experience.
Advantages
The special conformation of ACCM allows it to reach excellent performances in terms of transmission capacity (Ampacity + 100%), strength (Tensile Strength + 20%), flexibility/ safety (Multiwire Core) and lightness (Core Weight – 50%) compared to a standard ACSR conductor.
