Overhead Conductor Cable Sizes

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.

Overhead conductor cable sizes. Insulation select the thermal rating of the insulation on the wire. 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 aluminum wires in a round wire stranded conductor leave approximately 25 of an air gap between the aluminum strands. Common conductors are copper and aluminum.

Accr or other types of conductors. 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. One of these wires is a ground wire which can be sized down. An overhead line with bare conductors insulated by air is typically less costly than a cable with insulated conductors.

Aac aaac acsr form part of the family of overhead conductors transmission conductors and power distribution conductors. The steel core may consist of a single wire 7 19 37 or more concentrically stranded wires. To calculate ground wire size use the ground wire size calculator. Conductor choose the material used as a conductor in the wire.

Overhead transmission line acsr conductor with multi size. A conductor is one of the most important components of overhead lines. These cables are formally known as all aluminium conductor aac all aluminium alloy conductor aaac and aluminium conductor steel reinforced acsr. All aluminium conductors steel reinforced acsr consists of stranded or solid steel core enclosed by strands of aluminum.

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. Ampacity rating copper wire conductors. A more common approach is covered line wire. These acsr conductors are made available in broad range of steels varying from as low as 6 to as high as 40.

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.
