LV PVC Insulated Twisted Aerial Cables Single & 2 Core 3 & 4 Copper for Australia

Application Of Cu Aerial Insulated Cable

Aerial insulated cables are the cables of single-layer or multi-layer aluminum or copper strands twisted on top to extrude the insulation wire.

Overhead line is relative to the cable said, that is, and by the tower will be the wire at a certain height to transmit electricity lines. The ground insulation of overhead lines in high-voltage transmission and distribution networks generally depends on air, and the previous distribution lines (less than 10 kV except for 380 V) generally use bare conductors, but because of the complex distribution environment in urban areas, short-circuit grounding and lightning strike lines often occur, the reliability of power supply is reduced. Therefore, at present, the overhead lines below 10 kV generally use insulated conductors (i.e., the outer layer of conductors wrapped in insulation layer), which is called insulated overhead lines.

Note:

Reactance and voltage drop are based on three cables laid in flat formation spaced 0.46m apart. The values can also be applied to single-phase circuits or 3-phase circuits with cables in trefoil formation. For single-phase circuits the voltage drop values should be multiplied by 1.155. Continuous current ratings are based on an ambient temperature of 40℃ , maximum conductor temperature of 75℃ and solar radiation intensity of 1 OOOW/m2. Fault current ratings are based are on initial and final conductor temperatures of 75℃ and 150℃ respectively.
