Specialty Of Submersible Pump Cables

Submersible pumps find extensive application; from irrigation to offshore drilling rigs submersible pumps are integral part of various industries. Wide application and dependence on submersible pumps has led to various high quality and efficient submersible pumps in market. Hence the cables used for supplying power to submersible pumps also need to be highly reliable and safe. Cables for submersible pump also need to stay submersed in water and hence need to withstand exposure to water and wear all the time. Submersible pump cables besides being water resistant should also have tolerance for pressure. These pump cables should also be able to stand fluctuation in temperature and hence there are cables available, which can bear temperature ranging between -50°C to 105°C.

Submersible cables are also available for a wide range of voltage transmission ranging between 450 Volts to 3000 Volts. Few areas where submersible pump cables are employed include swimming pools, aquariums, hydraulic industries, manufacturing plants, irrigation, drinking water supply, mine dewatering, fountains, oil and other offshore drilling rigs, sewage treatment plants, sea water filtration cells, etc. Few qualities that are essential for ideal submersible cables include

Water-resistant

Submersible cables are used to supply power to pumps submersed in water and hence need to be exposed to water almost all the time. This makes it necessary that submersible cables have high tolerance against water for long periods of time.

Non-toxic

Submersible cables are also used to supply power to pumps used for water supply so they should in no way contaminate drinking water. There are cables available with ROHS PVC that is ideal for this.

Flexible and Tough

Submersible cables often have to be fitted in tight casings and at places where they may have to stand wear and high pressure. Hence the cables should be flexible and abrasion resistant for a long life.

Power saving

Submersible cables should have low electrical resistance against the current. This makes them power efficient and hence cost efficient. Cables manufactured from material such as bright-annealed 99.97% pure bare copper have very low voltage resistance.

Temperature resistant

Submersible cables may have to stand a high range of temperature variation. In areas such as oil wells, mines and off shore drills the temperature can rise invariably and in fresh water supply it can drop very low. This makes it essential for submersible cables to have high temperature tolerance.

Easy maintenance

Submersible cables should be safe against minerals and hydrocarbon oils, UV rays and chemical corrosion. This increases the working life of the cables and makes it convenient to maintain them efficiently.
