Powering a pump that is set underwater requires submersible cables to connect from the power source to the pump itself. There are a few different wiring styles that can be used depending on the situation. The environments that call for wiring such as these include deep wells, dewatering tanks, pumps submerged in water depths of 500 meters and for areas that supply drinking water.
PVC 3 core flat and PVC 4 flat styles are used in environments that have pumps that are submerged in deep well situations. They are comprised of 3 and 4 wires depending on the model. These styles of wiring are designed to be implanted into very hostile areas. Since the areas are so dangerous additional precautions are taken during manufacturing to ensure protection against grease, moisture, abrasion, and oil permitting for a long flex life.
PVC 3 core round and PVC 4 core round wires are designed for areas that have a lot of sewage and other acidic qualities. They are available in 3 and 4 wires depending on the connection requirements of the pump unit. This style of cable is often used in dewatering pump applications. The design also provides protection against abrasion, acidic fluids and chemicals.
The rubber 3 core and Rubber 4 core flat models are designed for power supplies connected to submersible pumps down to 500 meters of depth. Constructed with oil and water resistant thermoplastic rubber provides adequate insulation. To protect the core insulation an additional heavy duty thermoplastic rubber is applied. The extra protection allows for protection against surging water and friction from constant movement due to water fluctuations.
Like the flat version; the rubber 3 core and rubber 4 core round models also help prevent cuts and tears created from abrasions that can occur during time of use. The designs are weather resistant, impact resistant and also resistant to chemicals, oils and solvents. Depending on the pump location the round model could be a better option than the flat model.
The two kinds of AWG that are used consist of PVC and Rubber materials. The PVC model has the same qualities as others of its type. The added properties for this model are that it has excellent electrical properties and can is capable of passing up to 600 volts through it. This makes the model ideal for deep well pumps. The rubber version of this model also can handle 600 volts of electricity. This model is more ideal for use in fresh or saltwater deeply submersed pumps.
The drincable is designed for drinking water supply areas. The model incorporates the same qualities as other models and is made of non toxic material and has the appearance of vulcanized rubber in its design. The insulation that is used water resistant EPDM base rubber and the sheath is constructed of black heavy duty EPDM base rubber providing protection against abrasions.
