110KV & 220kV ACSR conductor busbars 400/25

Used as bare overhead transmission cable and as primary and secondary distribution cable. ACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity.
  • ACSR
  • Grand Cable

Description:
 

The use of Aluminium as a material for electrical conductors has greatly developed mainly due to its electrical properties. However, Aluminium conductors for most of transmission lines which spans are quite long, it is necessary an additional mechanical support. Commonly it is used galvanized steel wires for cores of ACSR.

Application:

Widely used as bare cable for overhead transmission lines and also as primary and secondary bare cable for distribution lines.

Construction:

ACSR is concentrically stranded conductor with one or more layers of Aluminium wire hard-drawn 1350-H19 on the galvanized steel wire core. The core may be single wire or stranded depending on the size. Steel wire is available in Class A or B galvanization as corrosion protection.

ACSR is according to electrical and mechanical strength requirements of transmission or distribution lines, can provides an appropriate design combining the quantity of Aluminium and galvanized steel wires.
