Submersible flat cables are cables that are designed to be used in underwater or submersible applications. These cables are typically used in pumps, motors, and other submerged equipment, and are constructed to withstand the harsh conditions of being submerged in water or other liquids.

Submersible flat cables are usually made with a flat, ribbon-like shape that allows them to be easily installed in tight spaces and around corners. They are also usually made with a durable outer jacket that provides protection against moisture, chemicals, and abrasion.
