With the widespread presence of electronics around us, we are sometimes faced with some unique challenges. One of these is dealing with aggressively hostile environmental conditions. For instance, underwater and partially submerged equipment. Apart from installing the equipment, we also need cabling. This is where submersible flat cable India come in. These cables are designed to be used in submersible and semi-submersible conditions.
The most common equipment found in submersible conditions is the submersible pump. Used to pump liquid, these pumps are often submerged or semi-submerged in water. We find them in many places — irrigation pumps, water coolers and other many important applications. The cabling with such pumps has to be adept enough to deal with these conditions.
Applications of submersible cables
Submersible cables are used with equipment like:
- Sewage pumps
- Pond filters
- F&B industries
- Fire retardants
- Deep well drilling and boring
- Water wells
- Offshore oil drilling
As we can clearly see there are many uses of the submersible cables. Most of these are under extremely hostile conditions. In deep well drilling and boring, the cabling is submerged in water, mud and sediments. The corrosive elements here include the water, microbes and sharp objects. In the F&B industry submersible pumps have to be resistant to chemicals and microbes found in solutions. In other applications like oil drilling the corrosive materials includes grease, heavy oils and chemicals. They are also found submerged in highly harsh substances like sewage.
Other cables cannot function under the same conditions. Although most cables are made to meet the usual environmental conditions, they cannot meet the extreme hostile conditions under which some of the submersible flat cables Manufacturers are found. How do we ensure this high protection against corrosive elements?
The answer lies in its construction. The flat cable conductors are made of copper or aluminum, both of which are very good conductors of electricity with excellent resistance against many corrosive environmental factors like moisture and grease. However, this is just the core. The main ability to counter its environment comes from the jacketing material. Most cables have a specially developed PVC material that are resistant to chemicals, microbes and abrasions.
Why flat cables?
We understand why we need specially constructed submersible cables. But what is the need for flat cables? There are many reasons why we prefer a flat cable over round cables. Some of these are:
Flexibility: Flat cables are inherently more flexible than round cables. Their internal composition makes this the most flexible option. The conductors in a flat cable are aligned parallel. Unlike a round cable, they are arranged in a flat plane. It means that their bend radius will be a fraction of the round cables. This has special repercussions when we need the cables to be coiled. Round cables develop kinks or ‘corkscrew’ effect in repeated bending cycles. On the other hand, flat cable have 15-million flex-cycle life. In plain words, when we need the cable to be wound tightly with heavy flex cycling, flat cables are the better option. This is a very common requirement in underwater applications where the cable must move with the pump.
Space: The flat cable is designed to take a small space. The flat alignment means that the space occupied by a flat cable could be half that of a round cable! Flat cables are also more easily packed in small spaces.
Better/consistent performance: The geometry of a flat cable is consistent with even spacing of the conductors. The conductors are fixed in their position. This gives us a better performance in areas such as impedance, crosstalk, attenuation, inductance etc. flat cables also have a greater current carrying capacity. This is because their surface to volume ratio is higher than round cables. This makes their heat dispensing capacity more efficient. In other words, it can carry more current without the danger of overheating. Durability: One of the basic requirements of submersible cables is their durability. As explained above, these cables must perform in extremely hostile conditions and stay durable. The heavy jacketing and construction of the submersible flat cable India are made to last for long, able to withstand chemicals, microbes, moisture temperature fluctuations and abrasions.
