Overhead Conductor Cable Sizes

Common conductors are copper and aluminum.

Overhead conductor cable sizes.

Conductor choose the material used as a conductor in the wire. To calculate ground wire size use the ground wire size calculator. Overhead transmission line acsr conductor with multi size. Selecting a proper type of conductor for overhead lines is as important as selecting economic conductor size and economic transmission voltage a good conductor should have the following properties.

Acsr bare overhead conductor product construction acsr is a composite concentric lay stranded conductor consisting of a central steel core around which are stranded one or more layers of aluminum alloy 1350 h19 wires. The steel core may consist of a single wire 7 19 37 or more concentrically stranded wires. Aac aaac acsr form part of the family of overhead conductors transmission conductors and power distribution conductors. A more common approach is covered line wire.

The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient air temperature of 30 c 86 f. Electrical conductor wire size or gauge awg or kcmil. An overhead line with bare conductors insulated by air is typically less costly than a cable with insulated conductors. These acsr conductors are made available in broad range of steels varying from as low as 6 to as high as 40.

All aluminium conductors steel reinforced acsr consists of stranded or solid steel core enclosed by strands of aluminum. 73 electric utility trapezoidal wire tw conductors for overhead transmission conductor applications general cable supplies tw compact style conductors. General cable s transpowr overhead transmission conductors are 100 recyclable and help ensure maximum line efficiency and long lasting reliability for current and future power transmission systems. Accr or other types of conductors.

These cables are formally known as all aluminium conductor aac all aluminium alloy conductor aaac and aluminium conductor steel reinforced acsr. A conductor is one of the most important components of overhead lines. Insulation select the thermal rating of the insulation on the wire. It is treated as bare cable but often is safer for wildlife as the insulation on the cables increases the likelihood of a large wing span raptor to survive a brush with the.
