EPDM (Ethylene Propylene Diene Monomer) is a material that is well suited for insulation of low-voltage cables and wires for submersible pumps. It has excellent resistance to heat, weather, ozone, and chemical corrosion, as well as excellent electrical insulation properties, which make EPDM widely used in submersible pump cables in the petroleum and chemical industries.
In submersible pump cable applications, EPDM insulation materials are able to withstand high temperatures and harsh chemical environments while maintaining their physical and electrical properties. For example, some EPDM insulated submersible pump cables have insulation materials that can withstand temperatures up to 121°C (250°F) and are generally compliant with standards such as IEEE Std. 1018, API RP 11S5, and API RP 11S6.
The construction of a specific EPDM insulated submersible pump cable includes multiple bare copper conductors, EPDM insulation, NBR jacket, fluoropolymer tape, nylon braid, and galvanized steel tape interlocking armor. This cable is designed to reliably transmit electrical energy in downhole installations in the oil industry. The size and weight of the cable will also vary depending on the conductor specification and voltage level.
In general, EPDM is an ideal material for insulation of low-voltage cables and wires for submersible pumps due to its excellent chemical resistance and electrical insulation properties, and can provide reliable performance under extreme conditions.
