Conductors :
  All aluminum stranded conductor (AAC) & aluminum conductor steel
  reinforced (ACSR)


  


Application

AAC and ACSR have been widely used in overhead power transmission lines with various voltage levels, since they have such good characteristics as simple structure, convenient installation and maintenance, low cost for the line, large transmission capacity and are also suitable for laying across rivers and valleys with special geographical features, etc.

Type

The standard "Round Concentrically-stranded overhead conductors" GB/T1179-1999 equivalently adopts IEC 6089-1991 standard. For AAC's type contrast of new. old GB standards with IEC standard, see Table 1.

Anti-corrosion ACSR LGJF JL/G1AF, JL?G2Af, JL/G3AF

Our company can not only produce AAC and ASCR in the light of ASTM, DIN, BS, etc. according to the needs of our customers but also products nonstandard AAC and ACSR according to the customer's special requirements for cross section, structure and performance, and produce anti-corrosion ACSR according to the customer's needs of different anti-corrosion grades by way of applying an anti-corrosion coating between arbitrarily designated layers of the ACSR.

Note:
For cables of those in GB1179-83, there is still a lot of customers and a certain market during the transition from the old standards to the new ones, therefore they can be treated as nonstandard (or customers specially required) products

Specification

The product's specification number represents conductive cross section of hard round aluminum wire
As to the specification and structure of AAC, see Table 2.
As to the specification and structure of ACSR, see Table 3.

Material standard

The hard aluminum conductor used for AAC and ASCR implements GB/T17048 standard (equal to adopt IEC 60889 standard).
The mine-coated steel wire used for ACSR implements IEC 60888 standard.
According to the needs of customers, that is, the material standards and requirements put forward by customers, we organize our productions.

Product Performance

The electrical performance of AAC and ASCR is indicated in /(20). The resistance of the hard aluminum wire for conductors is not greater than 0.028264//m, the international standard value.
ACSR is divided into three strength grades, ie. common strength grade, high strength grade and extra-high strength grade.
For the performance of AAC, see Table 2.
For the performance of ACSR, see Table 3.

Product Maintenance

Any bump, press or damage should be avoided during handing and transportation
The cable drum shall not be placed flat during transportation and storage.
Moisture resistant measures should be taken during storage.

Notice upon ordering the cable

The customer should provide the following information during order or consult :
The type. specification number an stranding structure of the product.
The standard to be implemented.
Product quantity.
Stranding direction, (if not specially required, the outer layer is right-handed).
Anti-corrosion kind and requirement (If anti-corrosion is needed).
Cable length and deviation on each drum, short cable length suitable for project, and percentage of short cable in lot delivery.
Package kind and special package requirements.
Specially required test items, ways and test site.
Delivery data and delivery way.
