Clearly, the intended application (e.g. well water pump versus irrigation drain) determines which cable to buy, and where to source it from. However, it is also imperative that the cable manufacturer considers other factors in their submersible cable specification, including:
Last, but not least, when sourcing cables and wires, submersible pump cable price plays a very important role. However, do not make pricing the main determination factor when you set out to buy your stock of cables. While the price is very important, a “cheap” cable that does not conform to many of the other specification requirements listed above, might not be such a good buy.
Choose your submersible cable supplier with care. Because these wires and cables support highly sensitive and mission critical applications, buying your stock from relatively unknown suppliers may compromise your project.
