Product introduction

Aluminum stranded wire and steel-cored aluminum stranded wire have the characteristics of simple structure, convenient erection and maintenance,
low line cost, large transmission capacity, and favorable geographical conditions for crossing rivers and valleys. Therefore, the product is widely
used in various voltage levels. Overhead transmission and distribution lines.

Product implementation standards and models

GB/T1179-2017   Circular Concentric Stranded Aerial Wire" standard equivalent adopts IEC61089-1991 standard. The model comparison table of
new and old national standard and IEC standard of aluminum stranded wire and steel core aluminum stranded wire is shown in the following table.

The company can produce aluminum stranded wire and steel core aluminum stranded wire according to the requirements of users, according to
ASTM, DIMA, BS and other standards. It can also produce non-standard aluminum stranded wire according to the cross-section, structure and
performance requirements of users' special needs. Steel core aluminum stranded wire products, according to the user's need for different
anticorrosion
grades of the wire, can evenly apply anticorrosive paint between any specified layers of steel
core aluminum stranded wire to produce anticorrosive steel core aluminum stranded wire.

Note: The product model specifications of GB/1179-1983 standard still have a certain amount of users and a certain market between the new and old standards. Therefore, the order can be arranged as a non-standard product (or a product specially required by the user).

Material standard

Aluminum stranded wire and steel core aluminum stranded wire are hardened with hard aluminum wire to implement GB/T17048 (equivalent to IEC60889 standard)

Steel core aluminum stranded wire with galvanized steel wire to implement IEC60888 standard and GB/T3428

According to the needs of users, we can organize production according to the material standards and requirements put forward by users.

Product Standards

The electrical properties of aluminum stranded steel and steel-cored aluminum stranded wire are expressed in terms of kilometer resistance at 20 °C. The resistivity of the hard aluminum wire used for the wire is not more than the national standard value of 0.028264 Ω.mm2/m. The steel core
aluminum stranded wire is divided into three strength grades, namely: ordinary strength grade steel core aluminum stranded wire; high strength grade
steel core aluminum stranded wire and ultra high strength grade steel core aluminum stranded wire.

Product Maintenance

Extrusion and bumping should be avoided during loading and unloading and transportation of the product; the cable tray should not be laid flat during transportation and storage; moisture-proof measures should be taken during storage.
