AAC Cable/ AAC Conductor/AAC Bare Wire with ISO Certificate
1. Introduction of AAC Cable
All Aluminium Conducts are used in Transmission and Distribution system to carry the generated electrical energy from generating station to end user.
The Electrical energy is normally generated at the power stations far away from the urban areas where the consumers are located. There is a large network of conductors between the generating stations and the consumer.
The network is called the Transmission and Distribution system. The Transmission system is to deliver bulk power from power stations to the load centres and large industrial consumers beyond the economical service range of the regular primary distribution lines where as distribution system is to deliver power from power sector or substations to the various consumers. This transmission and distribution system can employ either overhead system or underground system.
2. Characters of AAC Cable
Transmission of power, overhead system mainly due to low cost and some other advantages.AAC for distribution of power carry out mostly the high voltage transmission. For transmission and distribution of electric power the conductor material used must have the following characteristics:
i) High conducting i.e. low specific resistance
ii) High tensile strength in order to withstand mechanical stress
iii) Low specific gravity in order to give low weight per unit volume
iv) Low cost in order to be used over long distance
v) Should not be brittle
3. Advantages of AAC Cable
Copper, Aluminium, Steel and Steel cored aluminium, galvanised steel conductors are generally employed for this purpose and preferably stranded in order to increase the flexibility (Solid wires, except of smaller sizes, are difficult to handle and when employed for long spans tend to crystallize at the points of support because of the swinging in winds). Stranded conductors usually have a central wire around which there are successive layers of 6, 12, 18, 24 wires. For 19 layers, the total number of individual wire is 3n (n+1). If the diameter of each strand is torn diameter of the stranded conductors will be (2n+1) d. In the process of manufacture adjacent layers are spiraled in opposite direction, so that the layers are bound together. This method of construction is called as Concentric Lay, out of above mentioned conducting materials, Aluminium is widely used due to its cheapness and many others comparative advantages over other conducting materials. The AAC conductors for high voltage transmission have first replaced the bore copper conductors where copper is scarce and costly on the other hand EC grade Aluminium is easily available and as far as the electric properties are concerned, aluminium is equally good being lighter in weight and for same sage span length of the transmission could be increased in comparison to copper.
