4、EEE Standards documents are developed within the Technical Com- mittees of the IEEE Societies and the Standards Coordinating Commit- tees of the IEEE Standards Board. Members of the committees serve voluntarily and without compensation. They are not necessarily mem- bers of the Institute. The standa
5、rds developed within IEEE represent a consensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE which have expressed an in- terest in participating in the development of the standard. Use of an IEEE Standard is wholly voluntary. The existence of
6、 an IEEE Standard does not imply that there are no other ways to pro- duce, test, measure, purchase, market, or provide other goods and ser- vices related to the scope of the IEEE Standard. Furthermore, the view- point expressed at the time a standard is approved and issued is subject to change brou
7、ght about through developments in the state of the art and comments received from users of the standard. Every IEEE Stan- dard is subjected to review at least once every five years for revision or reaffirmation. When a document is more than five years old, and has not been reaffirmed, it is reasonab
8、le to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. Comments for revision of IEEE Standards are welcome from any interested party, regardl
9、ess of membership affiliation with IEEE. Sug- gestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally questions may arise regarding the mean- ing of portions of standards as they relate to spec
10、ific appiications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it is important to ensure that any interpretation has also received th
11、e con- currence of a balance of interests. For this reason IEEE and the mem- bers of its technical committees are not able to provide an instant re- sponse to interpretation requests except in those cases where the mabter has previously received formal consideration. Comments on standards and reques
12、ts for interpretations should be ad- dressed to: Secretary, IEEE Standards Board 345 East 47th Street New York, NY 10017 USA Foreword (This Foreword is not a part of IEEE Std 1019-1985, IEEE Recommended Practice for Specifying Electric Sub- mersible Pump Cable-Polypropylene Insulation.) This recomme
13、nded practice, under the jurisdiction of the IEEE Industry Applications Society, Petroleum and Chemical Industry Committee, presents minimum requirements for the construction, manufacturing, purchasing, and application of electric submersible pump cable. The configuration of the cable is round, with
14、 polypropylene insulation, nitrile jacket, and armor. This recommended practice may be used by anyone desiring to do so and is presented as minimum criteria for construction of this class submersible cable. It is not intended to restrict innovation or to limit development of improvements in cable de

25、his recommended practice establishes re- quirements for a three-conductor round-type oil- well cable used in supplying three-phase ac electric power to submersible pump motors. Ca- bles meeting the requirements of the recom- mended practice should be rated for voltages not exceeding 3 kV or 5 kV and
26、 for ambient temper- atures not exceeding 167 O F (75 “C). Use of cable above rated temperature can cause premature deterioration of the insulation. The cable de- fined herein is not recommended for installation below a temperature of 14 O F (-10 “C). Voltage ratings are nominal phase-to-phase ratin
27、gs. 1 . 2 Cable purchased under the recommenda- tion of this document, unless otherwise specified herein, should meet the requirements of the doc- uments listed in Section 2: l, 2, 131, 41, 151, 61, 7, 8, where applicable. 1.3 This recommended practice recognizes the common practice to continue oper
28、ating the pump 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. The purpose of this recommended practice is not to condone or dis- approve such practice, but the user should be aware such op
29、eration produces a higher than normal phase-to-ground voltage across the insulatiodjacket dielectric of the two unground- ed conductors; due to the disruption of the nor- mally balanced three-phase field, such operation produces stresses through the insulatiodjacket dielectric which shortens cable l
30、ife. ICEA S-61- Numbers in brackets correspond to those in Section 2, References, of this guide. 402-1973 81 recommends a 173% insulation level for grounded-phase operation, but this is often impractical for downhole oil well cable; therefore, this specifying standard recommends insulation thickness
31、es based upon a normal three-phase energized delta or wye system, with no phase grounded. 2.
