EPDM Insulated and Lead/EPDM Sheathed, Galvanized Steel Strip Armoring, Round Cable for Submersible Oil Pump
Product Overview
This heavy-duty round cable is engineered for Electrical Submersible Pump (ESP) systems in oil production. Designed for harsh downhole conditions, it combines EPDM insulation with a unique lead and EPDM dual-sheath construction, finished with galvanized steel strip armoring. This robust design ensures reliable medium-voltage power transmission in high-temperature, high-pressure, and corrosive well environments.
Key Features & Benefits
-
Extreme Temperature Tolerance: Rated for continuous operation at temperatures up to 232°C (450°F) and resistant to cold environments as low as -40°C.
-
Superior Protection System: The lead sheath provides a hermetic barrier against moisture, gases, and well fluids, while the outer EPDM sheath offers additional chemical and mechanical protection before armoring.
-
Maximum Mechanical Strength: Galvanized steel strip armoring delivers exceptional crush resistance and tensile strength, protecting the cable during installation and operation in deep wells.
-
Industry Standard Compliance: Manufactured to meet critical API and IEEE standards for ESP systems, ensuring reliability and performance.
-
Round Construction: Offers balanced mechanical properties and is suitable for various downhole installation configurations.
