Start a Electric Wires & Cables Making Plant




(141)  Start a Electric Wires & Cables Making Plant
Electric wires and cables have become such an important part of everyday life that without them the world as we know it would simply not exist. For without wires and cables the existence and operation of conveniences such as electric lights, telephones, computers and a host of other household appliances would not have been possible. Moreover, as the standard of living rises, so does the demand for those types of products. Consequently, there has been an incredible increase in the demand for electric wire and cable. As developing nations around the world continue to develop, this demand will undoubtedly continue to rise.
     For example, Taiwan, the Republic of China, a country with a population of only 19 million, has more than one hundred factories successfully producing electric wire and cable to satisfy the needs of the domestic market. According to an estimate made in 1984,the total production of electric wire and cable had reached a level of 200,000 tons per year. Furthermore, the vast majority of this cable was purchased domestically by retailers, manufacturers, construction contractors, and the government owned power and telephone companies. Clearly, the establishment of an electric wire and cable making plant is a project worthy of investment.
     The wire and cable making plant described in this particular proposal is designed for the production of wire and low voltage (below 600V) power cable. It is not intended to be used for the production of telecommunication or high voltage power cable, as the plants capable of producing these types of cable are considerably more expensive and require a higher level of technical knowledge to set up. The types of wire and cable which can be produced by the machinery outlined in this proposal are classified as follows:
I.     Single wire: PVC insulated single copper conductors.
II.    Multiple wires: PVC insulated copper conductors consisting of 7-61 stranded wires.
III.     Flexible wire: single or twin core, PVC insulated cords consisting of 20-100 fine copper wires.
IV.     Flat twin-cord wire: twin core, PVC insulated single or multiple copper conductors, sheathed with PVC layers.
V.     Power cables: three of four cores of PVC insulated multiple copper conductors assembled together.
VI.     Armour cable: power cables consisting of three or four round and shaped cores armored with steel wires and sheathed with PVC layers. 
2.   General Process Information
2.1.   Process Description(1) Drawing
Bulk copper is formed into wire of varying diameters by drawing it through a series of dies.
(2) Annealing
Since the drawing process causes the copper to become hard and brittle, it should be annealed.
(3) Stranding
Anywhere from 20-100 (very fine copper conductor wires) are twisted into cords which will be used in making flexible wire and cable.
(4) Twisting
Layers of wires (1+6+12+18+24 etc.) are stranded together to make copper conductors. The maximum nominal cross-section area of a power cable core is 500m㎡.
(5) Insulating
The copper conductors, whether they are single wire or multiple stranded wire, are covered by PVC for current insulation.
(6) Lay-up
Three or four of these PVC insulated copper conductors are assembled into power cables.
(7) Sheathing
Complete cables are formed by sheathing twin-core or multiple-core PVC insulated copper conductors with PVC.
(8) Armoring
Special purpose power cables must be surrounded with steel wires in order to increase the cable structure strength.

Mini plant
30 Tons/month
45 Tons/month
Small plant
60 Tons/month
90 Tons/month
Medium plant

3.2.   Raw materials- - PVC grain (30% of the product weight)
- - 8.0mm or 2.6mm diameter copper rod (70% of the product weight)
In order to save money for the beginning investors, it is more economical to purchase 8mm (or 2.6mm) diameter copper rod and PVC grains as raw materials. These raw materials can be supplied by Taiwan. For the detail information, please contact the supplier in Taiwan.
