The standards developed within IEEE represent a con- sensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE that have expressed an interest in partic- ipating in the development of the standard. Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a docu- ment is more than five years old and has not been reaffirmed, it is reason- able 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 inter- ested party, regardless of membership affiliation with IEEE. Suggestions 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 specific applications. When the need for interpretations is brought to the attention of IEEE, the Insti- tute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it is impor- tant to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason IEEE and the members of its technical committees are not able to provide an instant response to inter- pretation requests except in those cases where the matter has previously received formal consideration.

Foreword (This foreword is not a part of IEEE Std 1018-1991, IEEE Recommended Practice for Specifying Electric Submers- ible Pump C a b l e Ethylene-Propylene Rubber Insulation.) This recommended practice, under the jurisdiction of the Petroleum and Chemical Industry Committee of the IEEE Industry Applications Society, presents minimum requirements for the construction, manufacturing, purchasing, and application of electric submersible pump cable. The configuration of the cable is either round or flat, with ethylene-propylene rubber insula- tion, nitrile jacket, and armor. Anyone desiring to use this recommended practice may do so. It is presented as minimum criteria for construction of this class of submersible cable. It is not intended to restrict innova- tion or to limit development of improvements in cable design. Every effort has been made to assure the accuracy and reliability of the data contained herein; however, the committee makes no representation, warranty, or guarantee in connection with the publication of this specification and hereby expressly disclaims any liability or responsibility for loss or damage resulting from its use, for any violation of any federal, state, or municipal regulation with which it may conflict, or for the infringement of any patent resulting from the use of this doc- ument.

Scope This recommended practice establishes requirements for three-conductor round-and-flat- type oil-well cables used in supplying three-phase ac electric power to submersible pump motors. The major cable components are: copper conductors, ethylene-propylene diene mono- mer (EPDM) insulation, nitrile jacket, and galvanized armor. Cables meeting the require- ments of the recommended practice shall be rated for voltages not exceeding 3 kV or 5 kV and for conductor temperatures not exceeding 284 O F . Use of cable above rated temperature can cause premature deterioration of the insulation and jacketing. Voltage ratings are nominal phase-to-phase ratings. Cable purchased under the recommendation of this document, unless otherwise specified herein, should meet the requirements of ASTM B3-1990 5f, ASTM B8-1991 S I , ASTM B33- 1991 1 7 1 , ASTM B189-1990 8, ASTM B496-1992 SI, and ICEA S-68-516 lo, where applica- ble. 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. The purpose of this recommended practice is not to condone or disapprove such practice, but 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. ICEAS-68-516 lo1 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 thicknesses based on a normal three-phase energized delta or wye system, with no phase grounded.

Conductors 3 . 1 Material. Conductors should be annealed, coated, or uncoated copper in accordance with ASTM B3-1990 C 5 1 for uncoated conductors, in accordance with ASTM B33-1991 7 1 for tin- coated conductors; or in accordance with ASTM B189-1990 1 8 1 for lead or lead-alloy coated conductors. 3 . 2 Construction. Conductors should be solid or concentric-stranded as shown in Table 1. Concentric-stranded conductors should conform to ASTM B8-1991 SI, and interstices should be filled for gas blockage. Compact round conductors, if used, should conform to ASTM B496- 1992 C 9 1 , with diameters approximately 92% of corresponding noncompact conductors. 2NFPA publications are available from Publications Sales, National Fire Protection Association, 1 Batterymarch 'MI publications are available from the Publications Section, American Petroleum Institute, 1200 L Street NW, 4AS!l'M publi
