Feedthrough System Withstands Up To 450F

ITT Interconnect Solutions has announced a high-temperature electric power feedthrough system for submersible pumps specifically designed for operation with conductor temperatures up to 450F (230C). Such a severe operating environment places significant demands on the individual components and stresses sealing elements of the system. ITT Interconnect addressed these issues by re-engineering the power feedthrough, incorporating a keying system and a new sealing system.

The engagement system between the BIW high-temperature feedthrough and the mating surface connector includes the Metal-Lok keying system, 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 feedthrough are protected by a new sealing system, which can withstand extremely high temperatures, 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 system has received CSA approval for use in Class I, Division 1 hazardous locations. Electrical ratings are 5,000V AC for up to 140A and pressure rating is 3,000psig.

ITT Introduces Packer Feedthrough System

The BIW field-attachable packer feedthrough system launched by ITT Interconnect Solutions is designed to provide a faster method of passing power cables through packers. Consisting of a field-attachable feedthrough connector, a mating attachable cable connector, a cross-over adapter and related hardware, this system allows the connector to be installed on the top side of a packer using a cross-over adapter, eliminating the need for splicing of down-hole cables.

Potential stress on the cable is eliminated as the packer feedthrough includes a completely variable threaded adjustment system, allowing vertical adjustment of up to 3in (76mm). When appropriate, it is possible to install the termination contacts on the cable conductors before the cable is passed through the packer. This may reduce the amount of work an installer is required to carry out in a vertical position over an open well.

Electrical specifications include voltage ratings of 5,000V AC, 140A current, pressure up to 5,000psig and maximum conductor temperature of 350F (175C). The field attachable packer feedthrough system has a maximum diameter of 2.6in (66.04mm); length above the packer with round cable is 26.4in to 29.5in (672mm to 748mm), and with flat cable 30.4in to 33.4in (772mm to 848mm).
