Bare Al stranded conduct are normally used for overhead electric power transmission. It includes Al stranded conductor and Al conductor steel-reinforced.
ACSR core cable features aluminium bare conductor of outside layers for electric power transmitting with steel wire of inside layer for reinforcing. The base material for steel wire could be fully-killed steel: zinc-coated (galvanized-GZ), Aluminium-coated (Aluminized AZ) and Aluminum-clad (AC). ACSR can be added grease for additional corrosion protection.
We, as one of the top wire and cable manufacturers supply these cables such as fire rated control cable according to IEC61089 BS 215. More than 20 years knowledge in cables industry, we supply reliable cables worldwidely inculding control cables, building wire, electric wire, power cable, control cable, flexible cable, screen cable, armoured cabel, LSZH cable. We can supply the cables according to the standard of BS, AS/NZS and IEC.
If you want to know about the acsr cable price, we as a professional acsr conductor manufacturer will help you. Please feel free to contact us.

Description of Overhead Bare Al Stranded Conductor
Conductor: AL round wire
Standard: BS215, IEC61089
Insulation: non-insulated
Range of application: overhead power transmission and distribution
No or strands: 7 strands, 19strands,37 strands and 62 strands
Application Of Overhead Bare Al Stranded Conductor
These cables are widely used for the power distribution lines with short distance and small load-carrying capability of the pole. The AAC is a good choice for overhead power transmission and distribution systems. This standard covers hard drawn copper conductor using for electric purposes and aluminum conductor steel reinforced.
