20mm2 ACSR Squirrel Conductor

ACSR Squirrel Conductor

The bare aluminum and ACSR conductors described here are suitable for installation in all practical spans on transmission towers, wood poles and other structures. Installations range from long distance EHV transmission lines to sub-service spans at distribution or utilization voltages on private premises. Widely used as bare cable for overhead transmission lines and also as primary and secondary bare cable for distribution lines.

Squirrel Conductor Size 20mm2 Features

With simple structure, the aluminum conductor steel reinforced is easy to set up and maintain, with low cost and high transmission capacity. It is advantageous for this ACSR to be put up across a valley or river or under other various special geographic conditions. The ACSR has advantages of sound electrical conductivity, high mechanical strength, high tensile strength, etc, and the pole distance can be lengthened. It is used for power transmission lines with various voltage levels and plays an important role in the electricity transmission field.

ACSR Squirrel Conductor 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.

ACSR Squirrel conductor strands 6 aluminums and 1 steel. But their diameter is the same, and they are 2.11mm. We can know the overall diameter is 6.33 mm. From the standard, we can know the nominal aluminum area of acsr squirrel conductor is 20 mm2. When you want to buy acsr weasel conductor, you should pay attention to this point. It isn’t suitable for the standard, and it is reasonable. The aluminum part cross section is 20.94mm2 and steel part corss section area is 3.49mm2. So total sectional area for ACSR suireel concutor is 24.43mm2. After the cabling, the acsr squirrel conductor weight per km total linear mass is 85 kg/km. Through the test, the calculated breaking load should be 7880 daN. At the 20℃, calculate D.C. resistance should be 0.1.368Ω/km.
