AAC Conductor Cockroach 250mm2 Application

AAC Conductor Cockroach 250mm2 can be used in low and medium voltage overhead lines. It’s commonly used in urban areas because of its ability to carry significant voltages over short distances. The long-lasting, corrosion resistant qualities of aluminum make this conductor a popular choice for use in coastal areas as well as for use in the railway and subway industries. Shipyards and offshore construction sites benefit from the conductor’s durability. AAC Conductor Cockroach 250mm2 can be used for most overhead transmission duties when conductor strength is not a factor. The conductor can also be used for primary and secondary distribution applications.

AAC (all aluminum conductor) is the most economical bare overhead conductor due to its lighter weight. It offers easier handling during installation and use of simpler fittings. The wire is corrosion resistant due to its homogeneous construction.

Construction

AAC Conductor Cockroach 250mm2 Construction
The aluminium wires used in the construction of the conductor shall be material GIE in the H9 condition as specified in BS 26273). a conductor consisting of seven or more aluminium wires of the same nominal diameter twisted together in concentric layers. When the conductor consists of more than one layer, successive layers are twisted in opposite directions
