ASTM 477 MCM ACSR Cable Voltage: Low Voltage/Middle Voltage/ High Voltage Conductor Type: Stranded Conductor: Aluminum Alloy 1350 Origin Place: China
ASTM 477 MCM ACSR Cable
Aluminum Alloy 1350 wires ,concentrically stranded around a steel core available with class A,B or C galvanizing ; Aluminum Coated (AZ), or aluminum-clad steel core (AL).Additional corrosion is available through the application of grease to the core or infusion of the complete cable with grease .
ACSR bare cable meets or exceeds the following ASTM specifications :
B-230 Aluminum wire ,1350-H19 for electrical purposes;
B-231 Aluminum conductor ,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
B-500 Metalic coasted stranded steel core for aluminum conductors, steel reinforced.
Used as bare overhead transmission cable and as primary and secondary distribution cable .ACSR offers optimal strength for line design. Variable steel core stranding for desired strength without sacrificing ampacity.
(1). The permissible long-time operating temperature for aerial conductor is 70oC.
(2). Under the circumstance that rare climate is occuring and ice coverage rate low in heavy ice area, the biggest stress of cable at the lowest point of the sag should not exceed 60% of the short-time destructive power.
(3). When connecting conductors, the conductor beside the connecting tube cant be prominent. Otherwise, the force on the operating conductors will be unbalanced. After connectors are install, the connecting tube should be painted by moisture-proof varnish in order to protect it from corrosion.
(4). Under installaion, the arc downing stress of all the conductors should be the same. With in the permissible distance of crossing buildings or dropping to the ground, the stress can be 10-15% higher than regular stress.
(1). The electrical performance of AAC and ACSR is indicated in DCΩ /km(20oC). The resistivity of the hard aluminum wire for stranded wires is not greater than 28.264 nΩ . M of international standard value.
(2). The rated tensile strength of AAC is denoted with the result of total cross-section of all aluminum conductors multiplied by min. Tensile of corresponding size specified in the standard for aluminum wire.
(3). The rated tensile strengh of ACSR is denoted with sum of all aluminum conductorstensile strength and steels tensile strength.
A. The tensile strength of all aluminum conductors is denoted with the result of all cross-sections of aluminum conductors multiplied by min. Tensile strength of corresponding size specified in the standard for aluminum wire.
B. The tensile strength of all steel wire is denoted with the result of all cross-sections of steel wires multiplied by the stress at 1% elongation of corresponding size specified in the standard for steel wire.
