AAC All Aluminium Conductor JL-600 – GB/T 1179-2017 Bare Overhead Stranded Cable, 61% IACS for Transmission Lines

AAC All Aluminium Conductor JL-600 – GB/T 1179-2017 Bare Overhead Stranded Cable, 61% IACS for Transmission Lines 

The JL-600 all aluminium conductor is a bare overhead stranded cable produced under GB/T 1179-2017, using electrical-grade aluminium wires laid in concentric layers. It carries current through its aluminium strands and relies on the same strands for mechanical support, as no steel core is present. With a rated conductivity of 61% IACS, the conductor supports efficient power transfer, while its bare surface forms a natural oxide film for outdoor durability. It is intended for transmission line installations where lightweight handling, simplified jointing, and stable electrical performance are valued.

Specification

 
Features

1. GB/T 1179-2017 and JL-600 Designation
Manufactured to the GB/T 1179-2017 standard and identified by the JL-600 type code, supporting consistent specification and procurement.

2. 61% IACS Conductivity
The aluminium strands provide a rated conductivity of 61% IACS, contributing to a low-resistance conductive path for overhead transmission duties.

3. All-Aluminium Stranded Construction
No steel core is used, so the conductor avoids dissimilar-metal contact at connections and simplifies cutting, splicing, and termination in the field.

4. Concentric Lay Arrangement
Aluminium wires are stranded in concentric layers, creating a uniform current path and allowing the use of standard overhead line fittings and hardware.

5. Bare Surface with Natural Oxide Protection
The uninsulated aluminium surface develops a thin oxide layer that resists weathering in outdoor service, reducing the need for added coatings.

​

Application

1. Overhead Transmission Lines. Used as a bare conductor on utility transmission routes where all-aluminium construction suits the span and loading conditions.
2. Medium Voltage Distribution Feeders. Installed on pole lines serving residential, commercial, and light industrial loads.
3. Substation Bus and Jumper Connections. Applied for internal connections where low resistance and easy handling are beneficial.
4. Rural and Remote Electrification. Selected for agricultural and remote routes where lightweight conductors simplify installation across difficult terrain.
5. Reconductoring and Line Extensions. Deployed to replace ageing conductors or extend existing overhead circuits in transmission and distribution networks.

​

Packing & Delivery
Wooden drums with dimater 1.1m, 1.2m, 1.6m, 1.8m and 2.2m etc.

Aluminium conductors are commonly wound onto wooden or steel reels, which provide protection during transport and handling.
