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.

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
