BRB was established by Md. Mozibar Rahman in 1979 in the BSCIC Industrial area of Kushtia with production commencing in the following year. Rahman was convinced of the attractiveness of the sector as he knew the country’s electricity requirement would increase in future from the 10% outreach that existed at that time. At the initial stage, various obstacles affected production volume among which financial problems constituted the most severe impediment. This was ultimately resolved by Agrani Bank and Rahman restarted the business in 1983. In 1996, BRB expanded its operations and imported the latest machinery from Japan, Germany, India, Belgium and Italy to establish a second unit in order to meet the
increasing market demand. Ever since, BRB has grown in leaps and bounds to become the largest cable manufacturer in the country.

HOW THE CABLES ARE MADE

COVERING PROCESS

In the extrusion of plastics, raw compound material in the form of dough is fed from a top mounted hopper into the barrel of the extruder. Additives such as colorants and UV inhibitors are often used and can be mixed into the resin prior to arriving at the hopper. The process has much in common with plastic injection molding from the point of the extruder technology though it differs in that it is usually a continuous process. The material enters through the feed throat and comes into contact with the screw. The rotating
screw forces the plastic beads forward into the heated barrel. The desired extrusion temperature is rarely equal to the set temperature of the barrel due to viscous heating and other effects. In most processes, a heating profile is set for the barrel in which three or more independent PID controlled heater zones gradually increase the temperature of the barrel from the rear to the front.This allows the plastic beads to melt gradually as they are pushed through the barrel and lowers the risk of overheating which may cause degradation in the polymer. Extra heat is contributed by the intense pressure and friction taking place inside the barrel. In fact, if an extrusion line is running certain materials fast enough, the heaters can be shut off and the melt temperature maintained by pressure and friction alone inside the barrel. In most
extruders, cooling fans are present to keep the temperature below a set value if too much heat is generated. If forced air cooling proves insufficient then cast-in cooling jackets are employed.

Application of Cu and Al wires
A. Copper wire: Copper is very useful metal, which has several practical usages in every sphere of life. Due to its excellent electrical conductivity and thermal conductivity, copper wire is now the most widely used material in electrical and manufacturing industry.
Some of the practical uses of copper wire are as follows:
i) Electrical Appliances: It is estimated that more than 65% of all copper produced in eventually used for electrical appliances. In the field of power generation and transmission, copper wire is extensively used in generators, transformers, motors, busbars and cable wires which are used for effectively and efficiently transmitting power to our homes and offices.
ii) Electrical Equipments: Copper wire is now the most preferable material for electrical equipment such as providing circuitry and wires for TVs, DVD Players, Computers and Laptops.
iii) Energy Efficiency: Copper related products are now widely used for creating energy efficient products and services. For instance, if 1 tonne of copper is used efficiently for manufacturing process, it can reduce carbon dioxide emissions by 200 tonnes every year.
B. Aluminium wire: Aluminium building wire for low voltage feeders where the savings over copper is significant due the higher weight. Aluminium building wire will have half the weight of copper even though the aluminium conductor must have 50% greater area than copper to carry the same current. The aluminium conductors used for building wire may be compacted in such a way that the overall diameter of the aluminium wire is approximately the same as copper. These wires are manufactured from E.C.grade aluminium. These wires are sold to a variety of clients like wire and cable manufacturers, winding wire
manufacturers, and a wide variety of miscellaneous engineering applications.

ACHIEVEMENTS

In recognition of its achievements, BRB Cable Industries has received important national and international awards like the National Export Award (Gold) – 1997-98, Sher E Bangla Fazlul Haque Gold Medal, 10th Golden America Award, Bangladesh Business Awards 2006 etc. Rahman acknowledges the support extended by his employees, customers, suppliers and financiers for his phenomenal success today.

CONCLUSION

BRB’s business has boomed over the last ten years with growing domestic demand. Turnover itself has more than doubled in the last five years and now stands at Tk 2.9 bln. Production capacity ranges between 12,500 and 14,000 metric tons per year in a factory size of almost 600 thousand square feet.
