Frequently Asked Questions from TANO CABLE

High voltage power cable are designed for distribution of electrical power with nominal voltage 500KV or below.

Concentric cables are generally used by distribution network operators linking electrical networks and towers to home or business. Suitable for direct burial, they are also used for sub-mains in high rise towers and street lighting systems.

AAC (all aluminum conductor) is the most economical bare overhead conductor due to its lighter weight. It offers easier handling during installation and use of simpler fittings. The wire is corrosion resistant due to its homogeneous construction.

Because it would add a lot of weight - and could very seriously risk breaking the lines for not much gain in benefit. It isn’t needed, the insulation, hence why the power towers are tall to keep the cables away from harming anybody.

Stranded is typically used to enable to pull the wires through conduit. Solid wiring can be passed through short pieces of conduit, but that is about it. Of course, stranded is always used where cables need to flex.

Although flat jacketed cable can be constructed from the same range of wire types as those used in ribbon cable, in practice this configuration is usually restricted to vinyl insulated wires and vinyl jackets. Special techniques have been devised which keep the outer jacket from fusing with the primary insulation, a condition which would make impossible the stripping of the jacket without damage to the individual wire coverings. While opaque jackets are generally specified, transparent materials are available, allowing the color-coded wires to be seen throughout the cable length.
