The cable 1200 includes braided fibers 1260 while the cable seven-hundred includes the cushion layer 760. In FIG. 12, the braided fibers 1260 (e.g., or braided layer) is made from polyethylene terephthalate (PET) fibers; while the cushion layer 760 is manufactured from a crosslinked polymeric materials, specifically including crosslinked polyethylene (XLPE). As to material cost, the cable 700 of FIG. 12 can exhibit lesser material cost when compared to the cable 1200 of FIG. 12. As extrusion can utilize a raw base polymer, the price of buying a resin that has been formed right into a fiber or tape could be prevented, as the resin can be bought in raw material pellet type for a lowest possible materials price. In the instance of FIG. 2, the VSD unit 270 may be a low voltage drive (LVD) unit, a medium voltage drive (MVD) unit or different type of unit (e.g., a high voltage drive, which may present a voltage in excess of about 4.Sixteen kV). The VSD unit 270 could also be rated with an ESP to supply for about 40,000 hours (5 years) of operation (e.g., relying on surroundings, load, and so on.).

A thermoplastic extrusion might be performed at an almost limitless velocity depending on the scale of the equipment used and the specifications of the method. The UNICONN™ motor controller can include management performance for VSD models resembling target speed, minimal and most velocity and base pace (voltage divided by frequency); three soar frequencies and bandwidths; volts per hertz sample and begin-up enhance; ability to begin an ESP whereas the motor is spinning; acceleration and deceleration charges, including begin to minimal pace and minimal to focus on pace to keep up fixed stress/load (e.g., from about 0.01 Hz/10,000 s to about 1 Hz/s); cease mode with PWM carrier frequency; base pace voltage choice; rocking begin frequency, cycle and sample management; stall safety with computerized velocity discount; altering motor rotation direction without stopping; pace drive; speed follower mode; frequency control to take care of constant velocity, stress or load; current unbalance; voltage unbalance; overvoltage and undervoltage; ESP backspin; and leg-floor. For VSD models, the UNICONN™ motor controller can monitor VSD output present, ESP operating present, VSD output voltage, supply voltage, VSD enter and VSD output energy, VSD output frequency, drive loading, motor load, three-section ESP operating present, three-part VSD enter or output voltage, ESP spinning frequency, and leg-floor.

For FSD controllers, the UNICONN™ motor controller can monitor ESP system three-section currents, three-part surface voltage, provide voltage and frequency, ESP spinning frequency and leg floor, energy factor and motor load. As an example, an ESP motor can include a 3-part squirrel cage with two-pole induction. Measurements of temperature alongside the size of the properly can provide for suggestions, for example, to understand situations downhole of an ESP. For instance, an ESP might embrace a hydraulic diaphragm electric submersible pump (HDESP), which is a positive-displacement, double-acting diaphragm pump with a downhole motor. For example, the UNICONN™ motor controller can interface with the PHOENIX™ monitoring system, for instance, to entry pressure, temperature and vibration knowledge and varied protection parameters as well as to supply direct present power to downhole sensors. Further, the controller 230 might include features of a motor controller and optionally supplant the motor controller 250. For instance, the controller 230 might embrace the UNICONN™ motor controller 282 marketed by Schlumberger Limited (Houston, Tex.).

As an example, the UNICONN™ motor controller can perform some control and knowledge acquisition duties for ESPs, surface pumps or other monitored wells. As an example, a flat type factor cable may be utilized in low clearance functions inside a bore or, for instance, in shorter run lengths the place a rise in temperature of a heart conductor just isn't an appreciable concern throughout operation. The electrical windings could also be formed from magnet wire that includes an electrical conductor and not less than one polymeric dielectric insulator surrounding the electrical conductor. In FIG. 7, the ability cable seven hundred includes three conductor assemblies where every meeting features a conductor 710, insulation 730, a metallic shield 750, a cushion layer 760 and an armor layer 780. In FIG. 7, the ability cable seven hundred is configured with a flat geometry; whereas, the power cables 701 and 702 are configured with a spherical geometry where conductors are considerably pie formed of their cross-section.
