IEEE 1019-2013 pdf free download – IEEE Recommended Practice for Specifying Electric Submersible Pump Cable—Polypropylene Insulation.
1.1 Scope
This recommended practice establishes requirements for three-conductor round-and-flat-type oil-well cable used in supplying three-phase ac electric power to submersible pump motors. The major cable components are copper conductors, polypropylene insulation, polymeric jacket, and galvanized metallic armor.
1.2 Specification and standards Cables meeting the requirements of this recommended practice should be rated for voltages not exceeding 3 kV or 5 kV (phase to phase).
Conductor operating temperatures for cables should not exceed 96 °C (205 °F). Use of cable above rated temperature can cause premature deterioration of the insulation. Low-temperature handling below –10 °C (14 °F) may cause cracking of the insulation or jacket.
Cable purchased under the recommendation of this recommended practice, unless otherwise specified herein, should meet the requirements of ASTM A90, ASTM B3, ASTM B8, ASTM B33, ASTM B189,ASTM B496, ASTM D412, ANSI/ICEA S‐96‐659/NEMA WC71, ICEA S-19-81/NEMA WC3, and ICEA S-61-402/NEMA WC5, where applicable.
1.3 Application considerations
While operating temperature is the main factor in selecting the type of insulation to be used, there are many other factors that should be considered when choosing an appropriate electric submersible pump (ESP) cable design. Conductor size, insulation thickness, types of barriers or braids, jacket material, cable geometry, armor material and thickness should all be chosen with respect to specific well and operational factors including but not limited to:
The economic impact of conductor size selection
Starl-up urrent and maximum volage drop 10 assure moor starting
Voltage rating to optimize cable and system rum life
The projected hea rise duc to voltage imbalance
Available space between the tubing and the casing
The armount and type of gas in the well
Corrosiveness of the well environment
The efct of any corosion inhibitors or other chemical additives on insulation properties
The type of annulus fluid surounding the cable when it is set abowe a packer
The rate and frequency of decompression cycles
The magnitude and frequency of lemperature cycles
Crane pick weight capacity in off shore applications
Future uses for the cable beyond the well under consideration
Inclusion of chemical injection or communication lines in the cable
Wellbore tajectory
Clamping and bandling methods
Because there are so many considerations involved in making the proper cable selection, it is very important for the operator to engage the assistance of its supplier’s cable application engineers during the cable selection process. Each manufacturer has extensive experience with all the features and benefits of their particular cable offerings and its input can be invaluable in choosing the proper cable to maximize the value of cable investments. API 11S3 and API RP 11S5 contain information regarding the installation and application of submersible pump cable.
NOTE—While this recommended practice recognizes the common practice of continuing to operate the pump’s electrical system after a phase has faulted to ground and that some power distribution systems are even designed with one corner of the delta system grounded, it neither condones nor disapproves of such practice. However, the user should be aware that such operation produces a higher than normal phase-to-ground voltage across the insulation jacket dielectric of the two ungrounded conductors. Due to the disruption of the normally balanced three-phase field, such operation produces stresses through the insulation/jacket dielectric, which shortens cable life. For safety considerations, cable used on the surface between the wellhead and the ventilated junction box should be buried or enclosed in appropriate raceway and is properly grounded.IEEE 1019 pdf download.
