EPDM Insulated and Lead Sheathed, Galvanized Steel Strip Armoring, Flat Cable for Submersible Oil Pump

Product Overview

This specialized flat cable is engineered for Electrical Submersible Pump (ESP) systems in demanding oil well applications. It is designed to provide reliable medium-voltage power transmission in deep, high-temperature well environments. The construction features EPDM insulation, a continuous lead sheath for absolute moisture barrier, and galvanized steel strip armoring for maximum mechanical protection, ensuring long-term performance under extreme downhole conditions.

Key Features & Benefits

  • High-Temperature Rated: Conductor rated for continuous operation at temperatures up to 232°C (450°F).

  • Superior Downhole Protection: The combination of a hermetic lead sheath and robust steel armor provides unmatched defense against high pressure, mechanical damage, and corrosive wellbore fluids.

  • Excellent Environmental Resistance: EPDM insulation offers stable performance in oil, gas, and high-temperature environments. The cable maintains flexibility at low temperatures down to -40°C.

  • Industry Standard Compliance: Manufactured to meet critical API and IEEE standards for ESP systems, ensuring interoperability and reliability.

  • Flat Profile Design: Facilitates easier handling and installation along the production tubing in the confined space of a well casing.
