27、g Electric Submersible Pump CableEthylene-Propylene Rubber Insulation. This recommended practice, under the jurisdiction of the Petroleum and Chemical Industry Committee of the IEEE Industry Applications Society, presents the minimum requirements for the construction, manufacturing, purchasing, and
28、application of electric submersible pump cable. The configuration of the cable is either round or flat, with ethylene-propylene rubber insulation, with a nitrile jacket, EPDM jacket, or lead sheath and armor. Anyone desiring to use this recommended practice may do so. It is presented as minimum crit
29、eria for construction of this class of submersible cable. It is not intended to restrict innovation or to limit development of improvements in cable design.

Overview 1.1 Scope This recommended practice establishes recommendations for three-conductor round and flat oil-well cabl
38、es used in supplying three-phase ac electric power to submersible pump motors. The three major cables by components are as follows: a) Cables with copper conductors, ethylene-propylene diene monomer (EPDM) insulation, nitrile jacket, and metallic armor b) Cables with copper conductors, EPDM insulati
39、on, EPDM jacket, and metallic armor c) Cables with copper conductors, EPDM insulation, lead sheath, and metallic armor 1.2 Specifications and standards Cables meeting the requirements of the recommended practice should be rated for voltages not exceeding 3 kV or 5 kV (phase to phase).

41、 B3, ASTM B8, ASTM B33, ASTM B 189, ASTM B496, and ANSI/NEMA WC 71/ICEA S-96-659, where applicable.11.3 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 ap
42、propriate 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 econo
43、mic impact of conductor size selection Start-up current and maximum voltage drop to assure motor starting Voltage rating to optimize cable and system run life The projected heat rise due to voltage imbalance Available space between the tubing and the casing The amount and type of gas in the well Cor
44、rosiveness of the well environment The effect of any corrosion inhibitors or other chemical additives on insulation properties The type of annulus fluid surrounding the cable when it is set above a packer The rate and frequency of decompression cycles The magnitude and frequency of temperature cycle
45、s Crane pick weight capacity in offshore applications Future uses for the cable beyond the well under consideration Inclusion of chemical injection or communication lines in the cable Wellbore trajectory Clamping and banding methods Because there are so many considerations involved in making the pro
46、per cable selection, it is very important for the operator to engage the assistance of its suppliers 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
47、 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. NOTEWhile this recommended practice recognizes the common practice of continuing to operate the pump
48、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 p
49、hase-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. 1Information on references can be found in Clause 2.
