IEEE 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 standards 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 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 brought 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 reasonable 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, regardless 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 specific 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 the 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 requests 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 recommended 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 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 design.

IEEE Recommended Practice for Specifying Electric Submersible Pump Cable- Polypropylene Insulation 1. Scope 1.1 This 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 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 ratings. 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 operating 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 operation 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 life. 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 thicknesses based upon a normal three-phase energized delta or wye system, with no phase grounded. 2.

Conductors should be annealed, coated, or uncoated copper in accordance with ASTM B3-74 (R1980) l for uncoated conduc- tors, or in accordance with ASTM B33-74 (R1981) 41 for tin-coated conductors, or in ac- cordance with ASTM B189-80 5 for lead- or lead-alloy-coated conductors. 3.2 Construction. Conductors should be solid or concentric-stranded as shown in Table 1. Con- centric-stranded conductors should conform to ASTM B8-77 3 and interstices should be filled for gas blockage. Compact round conductors, if used, should conform to ASTM B496-74a (R1981) 6 with diameters approximately 92% of corre- sponding noncompact conductors. 3.3 Conductivity. Conductors should have a direct current resistance at 77 O F (25 “C) not to exceed the values listed in Table 1. 3.4 Gas Blockage. A one-foot specimen of insulated conductor removed from finished cable should be subjected to a 5 psi differential air pressure for a period of 1 h. 4. Insulation 4.1 Material. Insulation should be a ther- moplastic polypropylene meeting the properties shown in Table 2 when tested in accordance with ICEA S-61-402-1973 (R1979) 8, Section 6, except pull rate shall be 2 in/min. Polypropylene, when used with uncoated copper conductors, should be copper stabilized. 4.2 Construction. The insulation should be extruded on the conductor with an average wall thickness of 75 mils or more and with a mini- mum wall thickness of no less than 68 mils at any point for 3 kV-rated cable; or with an average wall thickness of 90 mils or more and with a minimum wall thickness of no less than 81 mils at any point for 5 kV-rated cable. 5. Assembly and Jacket 5.1 Material. The jacket should be an oil- resistant thermosetting nitrile rubber meeting Table 2 Polypropylene Properties Physical Requirements-Unaged Tensile Strength, Minimum, psi 3000 Elongation at Rupture, Minimum, Percent 350 Physical Requirements-Aged in Air Oven at 250 “F (121 “C) for 72 h Tensile Strength, Minimum, Percent of Unaged Value 75 Elongation, Minimum, Percent Retention 75 8 PUMP CABLE-POLYPROPYLENE INSULATION IEEE SM 1019-1985 Table 3 Nitrile Properties Physical Requirements-Unaged Tensile Strength, Minimum, psi 1800 Elongation at Rupture, Minimum, Percent 400 Physical Requirements-Aged in Air Oven at 212 “F (100 “C) for 1 wk Tensile Strength, Minimum, Percent of Unaged Elongation at Rupture, Minimum, Percent Retention Value 50 50 Physical Requirements-Aged in ASTM #2 Oil at 250 “F (121 “C) for 18 h Tensile Strength, Minimum, Percent of Unaged Elongation at Rupture, Minimum, Value 60 Percent Retention 60 the properties shown in Table 3 when tested in accordance with ICEA S-61-402-1973 (R1979) a, Section 6. 5.2 Construction. The three-insulated con- ductors should be cabled around a centrally located filler with a left-hand lay having a max- imum length of lay thirty-five times the individual conductor diameter. Over an assembly or three- insulated conductors and a central filler, a jacket should be extruded to fill all interstices with a wall thickness over the conductors of 60 mils average and 50 mils minimum thickness at any point. The jacket should have splines that should not be considered part of the specified wall. The jacket should separate cleanly from the conduc- tor insulation. 6. Armor 6.1 Material. The armor should be made from a galvanized steel strip. The nominal thickness of the steel strip prior to galvanizing should not be less than 25 mils. The nominal width of the steel strip should be no more than 6.1.2 The steel strip should be zinc-coated after slitting. The coating should be applied on 6.1.1 inch before forming. all surfaces by either the hot dip or elec- trogalvanizing process. 6.1.3 Tensile Strength and Elongation. The zinc-coated strip should have a tensile strength of not less than 40000 psi; and an elongation of not less than 10% in 10 in. All tests should be performed in accordance with ICEA S-61402-1973 (R1979) 8, prior to application of the strip to the cable. 6.1.4 Weight of Zinc Coating. The weight of zinc coating should be determined prior to application of the strip to the cable. The strip should have a minimum weight of coating of 0
