Aluminum 1350-H19 Bare Aluminium Conductor Steel Reinforced Wire

Bare Aluminium Conductor Steel Reinforced Wire is a specific type of high-capacity, high-strength stranded cable typically used in overhead power lines. The outer strands of ACSR cable are aluminum, chosen for its excellent conductivity, low weight and low cost. The center strand is of steel for the strength required to support the weight without stretching the aluminum due to its ductility. This gives the cable an overall high tensile strength.

Applications
Conductor(AAC and ACSR) 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.

Service Performance:
(1). The permissible long-time operating temperature for aerial conductor is 70℃.
(2). Under the circumstance that rare climate is occurring 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 installation, 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.
