Round Aluminium Clad Steel Wire For Overhead Conductor

 

(ACS) Aluminum Clad Steel Wires

Construction

Aluminum-clad steel wire, commonly abbreviated as AW or AS or AC, is an electrical conductor composed of an inner steel core and outer Aluminum cladding. Aluminum clad steel wire is a bimetallic in which aluminum covers on the steel core continuously and evenly.

Advantages

Aluminum-clad steel wire is superior to galvanized or aluminized steel in every way.

● Better corrosion resistance due to thick EC-grade aluminum covering

● Wider range of combinations of tensile strength and conductivity

● Lighter weight

● Excellent thermal stability

● Wider variety of products, with broad range of properties, quality, and size of steel wire and aluminum cladding.

● Compared with ordinary aluminum conductor steel reinforced, the conductor weight is 5% lighter, current-carrying capacity is 2-3% higher and power loss decreases 4-6%. Thus, the service life is long and it adds none erection cost.

 

Application

The aluminum clad steel wire is widely used in long-span transmission line, coastal areas and island as well as other hot and humid regions, salt fog regions and heavily polluted regions where the high corrosion resistance strand is needed.

 

It is used as the core of ACSR/AW, overhead ground conductor, extra high voltage overhead conductor, optical fiber composite overhead ground line, self-damping conductor line, bare overhead conductor, OPGW, ground wire, messenger wire, guy wire formed wire for protecting, terminating and splicing transmission and distribution lines, fence, barber wire and hardware, etc.

 

Standards

IEC 61232, ASTM B415, ASTM B502, AS 3607 and other International Standards.

However, can also supply a range of alternative designs with customized solutions to meet customer requirements.

  The design of an aluminum-clad steel wire with a specified conductivity is based on 61 % IACS of aluminum and 9 % IACS of steel. For example, the conductivity of 30% IACS is dealt with as follows: Designed conductivity: Aluminum (61 % IACS x 0.43) + Steel (9 % IACS x 0.57) = 31.36 % IACS. Then, taking into consideration allowances, minimum conductivity is specified as 30 % IACS (57.47 nΩm). When only the aluminum covering is taken into account as the conductive part in the conductor, the electrical resistance of aluminum-clad steel wires can be calculated by the cross-sectional area of aluminum as per above and the conductivity of 61 % IACS.
