Duplex / Triplex / Quadruplex Service Drop ABC Cable
Duplex / Triplex / Quadruplex Service Drop ABC cable
Used as bare overhead transmission cable and as primary and secondary distribution cable. ACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity.
Aluminum alloy 1350-H-19 wires, concentrically stranded about a steel core. Core wire for ACSR is available with class A, B, or C galvanizing; ""aluminized"" aluminum coated (AZ); or aluminum-clad (AW). Additional corrosion protection is available through the application of grease to the corer or infusion of the complete cable with grease.
ACSR bare conductor meets or exceeds the following ASTM specifications:
B-230 Aluminum Wire, 1350-H19 for Electrical Purposes
B-231 Aluminum Conductors, Concentric-Lay-Stranded
B-232 Aluminum Conductors, Concentric-Lay-Stranded, Coated Steel Reinforced (ACSR)
B-341 Aluminum-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced (ACSR/AZ)
B-498 Zinc-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced (ACSR/AZ)
B-500 Zinc Coated and Aluminum Coated Stranded Steel Core for Aluminum Conductors, Steel Reinforced (ACSR)
The permissible long-time operating temperature for aerial conductor is 70 .
The circumstance that long distance rare climate and ice coverage rare occurring in heavy ice area , the most biggest stress of cable at the lowest arc downing point should not exceed 60% of the distructive power at a short time .
When connecting conductors , the conductor near to the connecting tube can`t be prominient . Otherwise , the force on the operating conductors will be unbalanced after connectors are pressed , the connecting tube should be plated ny moistureproof paint in order to protect from corroding .
Under installation , the arc downing stress of all the conductors at home distance ot the ground and across building can be 10-15% higher than regular tension.
Any crush or bump should be avoided during handling and transportation of the product.
The cable drum is not allowed to be placed with one flange up and the other down during transportation and storage of the products.
A moisture-proof measure should be taken during storage of the product
Corrugated aluminium pipe busbar, made of aluminium wires or aluminium alloy wires stranded around aluminium pipe.
