ITT Interconnect Solutions is introducing a high-temperature electric power feedthru system for submersible pumps operating with conductor temperatures up to 230degC (450degF). This specialist power feedthru therefore incorporates an innovative proprietary keying system and a new sealing system.
The engagement system between the BIW high-temperature feedthru and the mating surface connector includes a new patented keying system, Metal-Lok, which prevents rotation of the surface connector should it be inadvertently turned or mishandled. In addition, seals between individual parts of the BIW high-temperature feedthru are protected by a new sealing system that can withstand extremely high temperatures, thereby preventing the ingress of downhole fluids. Exterior seals to the hanger and top flange have been fitted with high-temperature O-rings and back-up rings.
ITT Interconnect Solutions modified the exterior surface of the connector for improved heat transfer and better cooling properties. Internal insulators are manufactured from high-temperature Peek.
The BIW High Temperature Feedthru system has received CSA approval for use in Class I, Division 1 hazardous locations. Electrical ratings are: 5000V AC for up to 140A. Pressure rating is 3000psig.
