ACSR JL/G1A-300/40 is a power conductor with specific specifications and models, mainly used in the power and transmission line industries. The following is a detailed analysis of the product:

Product overview

Model: JL/G1A-300/40

Type: stranded wire

Wire core material: steel wire (internal steel core) and aluminum (external aluminum stranded wire)

Brand: Different manufacturers may produce different brands, such as AE Anhui Electric, Forbos, etc.

Application: It is widely used in overhead transmission and distribution lines of various voltage levels. Because of its simple structure, convenient erection and maintenance, low line cost, and large transmission capacity, it is especially suitable for large current transmission buses such as substations and power plants., And urban network capacity increase and transformation projects.

Technical parameters

Nominal section: aluminum wire part 300mm ², steel wire part 40mm ²

Structure: Single-layer or multi-layer aluminum strands stranded outside the galvanized steel core wire

Executive standard: GB/T1179-2017 "round concentric stranded overhead conductor" (note: articles published at different times may refer to different standard versions, such as GB/T1179-2008, but the core requirements are similar)

Use characteristics:

-The long-term allowable working temperature is 90 ℃, and the short-term temperature can reach 180 ℃.

-The continuous allowable current carrying capacity is 1.5~1.6 times that of the ordinary conductor of the same specification.

-At room temperature and ordinary aluminum wire has the same strength, high temperature operation mechanical strength retention rate can be maintained at more than 90%.

-The laying temperature of the cable is not limited, and the bending radius is allowed to be 30 times the cable diameter.

Product Features

High tensile strength: the steel core plays a role in increasing the tensile strength, so that the wire can withstand greater mechanical stress.

Good electrical conductivity: The external aluminum stranded wire is used as the main bearing electrical fluid and has good electrical conductivity.

Erection and maintenance is convenient: due to the simple structure and light weight, the erection and maintenance work is more convenient.

Good economy: Compared with other types of wires, ACSR has certain advantages in cost.

Manufacturer and Supply

Manufacturer: There are many manufacturers of ACSR in China, such as Hebei Fubos Wire and Cable Co., Ltd., AE Anhui Electric, etc.

Supply: complete product specifications, adequate supply, can be customized production according to user needs.

In summary, ACSR JL/G1A-300/40 is a kind of excellent performance, economical and practical power wire products, in the power and transmission line industry has a wide range of applications.
