JL/G1A-240/30 ACSR Cable High Conductivity Overhead Power Lines GB/T1179-2017

1. Product structure
ACSR is made of twisted aluminum wire and steel wire, suitable for overhead transmission lines.

It has a steel core inside, and aluminum wires are twisted around the steel core outside; the steel core mainly plays the role of increasing the strength, and the aluminum stranded wire mainly plays the role of transmitting electric energy;

2. Product model
The models of ACSR are: JL/G1A, JL/G1B, JL/G2A, JL/G2B, JL/G3A
Among them: G1A or G1B refers to ordinary strength steel wire.
G2A or G2B refers to high strength steel wire.
G3A refers to extra high strength steel wire.
Model difference: Take JL/G1A-240/30 ACSR as an example.
It is represented by the current JL/G1A-240/30 in the national standard (GB/T1179-2017);
It is represented by LGJ-240/30 in the national standard (GB/T1179-1983).

3. Implementation standards

This product implements the national standard GB/T1179-2017 "Circular Concentric Stranded Overhead Conductor"

4. Product application

ACSR is suitable for overhead power transmission and distribution lines of various voltage levels.

5. Product advantages

ACSR has the advantages of simple structure, convenient erection and maintenance, low line cost, large transmission capacity, and is conducive to the laying of special geographical conditions such as across rivers and valleys. It has good electrical conductivity, sufficient mechanical strength, and high tensile strength. , The tower rod distance can be enlarged and so on.
