FAQ
-
QWhat is the purpose of a concentric neutral cable?AConcentric 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.
-
QWhat does AAC stand for conductor?AAAC (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.
-
QSo why is it dangerous to coat the cables in insulation?ABecause 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. -
QWhy choose stranded wire in electrical applicationAStranded 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.

QFLAT CABLEAAlthough 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.

QWhat is benefits of ACSR conductors in transmission and distribution systems?A1.The conductance is higher than copper.
2.ACSR conductor is strong steel core light weight aluminum conductors available in a wide range of steel, which includes a carbon portion of 0.5 - 0.85.
3.These can be produced with flexible stamina in wide ranges as per the purpose for any resistance.
4.These type of conductors are also called as bimetallic conductors because it includes internal and external layers. The internal layers are of steel cables whereas the external layers are light weight aluminum that's hard-drawn.
5.The mechanical efficiency of the ACSR conductor is high.
6.The tensile stamina of the conductor is high.
7.Greater dependability because of the steel cables, which ensures the safety margins of the conductor.
8.Because of the highest mechanical resistance, better transport capacity, and high tensile stamina, the ACSR conductor can be used for medium and long spans and needs much less support.
9.The corona limit is high because of the high size of ACSR.
10.High voltage overhead lines are high.
11.Galvanic rust is avoided and steel cable is protected by covering with zinc.
12.Used for overhead ground cables, river crossings, and long-span installation purposes because of their highest strength.
13.Reduced weight and economical design.
