Specifications
We have attained ISO9001 & ISO14001certificates.Specification:IEC61089, BS215 part1, ASTM B231, DIN48201, JIS C3109, CSA C49Applications:
AAC have been widely used in power transmission lines with various voltage levels, because they have such good
characteristics as simple structure, convenient installation and maintenance, low cost large transmission capacity.
And they are also suitable for laying across rivers valleys and the places where special geographical features exist.
Features :
All Aluminum Conductor (AAC) 1350-H19 provides reliable performance in overhead transmission and distribution applications. AAC conductors are used in
line designs that do not require the strength of ACSR type conductors while maximizing current carrying capacity.
Construction:AAC cable is a concentric-lay-stranded conductor consisting of Aluminum alloy 1350-H19 wires available in both single layer and multi-layer constructions.
Service Performance
(1).The permissible long-time operating temperature for aerial conductor is 70°C.
(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.
Product Performance
(1). The electrical performance of AAC is indicated in DCΩ/km(20°C). 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.
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.
Package:In coils, wooden drums, steel drums or steel-wooden drums.
