Incorporating the most advanced materials and formulas, developed through decades of research and continuous testing, the REDA ESP power cables are designed and manufactured to maximize overall ESP system run life. While a basic configuration of the main components is suitable for most well conditions, each standard cable can be customized to suit the specific requirements of a given well, including temperature and pressure ratings, corrosive properties, and gas/oil ratios. Various grades of armor ranging from standard galvanized steel to Monel® alloys are available for protection against corrosive environments. All REDA ESP cables feature fully annealed, high-conductivity copper and tin lead-alloy-coated conductors for additional protection against corrosion. They also include best-in-class fluid and gas impermeable barriers and corrosion-resistant high-strength metallic armors.
The motor lead extension (MLE) designs provide the optimum combination of installation clearance and downhole performance. Polyimide is used as the primary insulation, which significantly reduces cable dimensions for a small profile. For extreme high-temperature or specialty applications, PEEK is used as the insulation material. The same patented and proprietary materials used in Schlumberger power cables are used in the MLE designs as secondary insulations and jackets to maximize system reliability.
