Power Transmission Products

Power transmission products are devices responsible to the movement of energy from one place to the object where it will be used. A common type of energy transported is electricity. It can either be delivered in bulk or individual. There are other systems applied for transmission of power before electricity. The main transmission systems occur through pressurized fluid, pressurized air and cable. In the 19th century, the use of electric power transmission system gained popularity as the advantages of electrical systems. However, the transmission of electric power encountered some obstacles. The voltage requirement of different devices such as street cars, residential lights and machineries vary. In order for them to function properly, each one would need a specialized generator or separate lines. Another difficulty that power transmission ran into is the location of generators. To make it possible Electricity can be delivered from long distances by raising the voltage. This act tends to be costly. To make the distribution less costly, the generators should be nearby the structure where transformed voltages will be applied. This is when the process of electric power distribution, the final stage of electricity delivery, is formed.

 

Electricity goes through various power transmission products or towers before it reaches home and businesses. These towers are made of electrical wires running from metal structures built either overboard or underground. Huge amount of electricity is generated in power plants. Transporting of electricity can only be done quickly if it can be moved in bulk volume. Power plants also tend to be located in secluded areas so the energy generated would have to travel long distances. To make transferring of electricity in bulk and in long distances possible, the use of high-voltage transmission lines is required. The power conveyed from this transmission line will then be received by subtranmission distribution lines. In this system, the high-voltaged power is lowered but not enough to be usable. It has to pass through local distribution lines which will turn the voltage into an adequate amount for the consumers to use.

 

Power transmission also occurs in automobiles. It has an engine or motor that serves as a power source and a gearbox as the power transmission product. The role of this type of transmission is to convert the speed that the power source generated into torque. The transmission in automobiles has two types: manual and automatic. Both work similarly in terms of converting speed into torque. They can also reverse the movement of the crankcase through a different engine that run in the opposite direction. A manual transmission allows one to reduce or increase the engine power by operating the clutch and a shifter manually. The gradual changes in the running speed of automobiles by shifting gears can prevent engines from getting damaged. Gears come in various sizes. The larger gears work by spinning slowly converting higher engine rpm into lower speed. Smaller gears, on the other hand, spins faster than the crankcase transforming lower engine rpm into higher speed. Automatic transmission uses the same principle as manual transmission. The difference is that it does speed-torque conversion through a torque converter. Instead of having a clutch that needs to be manually operated, the torque converter will automatically engage and disengage gears and a clutch pack that is hydraulically operated.
