Aluminum Conductors Steel Reinforced Electric Cable

Standards and Scope of Application
The products are used for aerial electric power transmission according to the standard ASTM , IEC , BS , CSA , NFC , and so on

Specific property for using
1.The permissible long-time operating temperature for aerial conductor is 70 C 
2.For long-span application in harsh environment such as heavy icing , the biggest stress of the cable at the lowest point on the span curve shall not exceed 60% of its breaking load.
3.When connecting conductors , the conductor near the connecting tube can’t be prominent. Otherwise , the force on the operating conductors will be unbalanced after connectors are pressed . The connecting tube should be plated by moistureproof paint in order to avoid corrosion.
4.In order to meet conductor-to-earth or conductor-to-building distance requirement during installation , the conductor stress can be 10%~15% higher than its permissible normal tension .

DESCRIPTION
The conductor consists of hard drawn aluminum wires and zinc coated steel wires built up in concentric layers . 
The centre wire or wires are zinc-coated and the outer layer or layers are alumnum wires .
The wires are stranded in successive layers in opposite direction . 

STANDARDS
Construction as per ASTM , IEC , BS , DIN , CSA , NFC ,and so on.

APPLICATION
ACSR bare conductors are used for overhead high tension power transmission lines having long spans .
