IEEE 1018-2013 pdf free download – IEEE Recommended Practice for Specifying Electric Submersible Pump Cable—Ethylene-Propylene Rubber Insulation.
For flat cable with additional constraining coverings, the average wall jacket thickness should be 1.3 mm (0.050 in). The minimum jacket thickness at any point should be no less than 1.0 mm (0.040 in). For flat cable without additional constraining covering, the average jacket wall thickness should be 1.5 mm (0.060 in). The minimum jacket thickness at any point should be no less than 1.2 mm (0.048 in).
6.2.3 Flat cable with lead sheath Each insulated conductor should have a lead sheath extruded over the insulation. The average wall thickness should be 1.0 mm (0.040 in). The minimum wall thickness at any point should be no less than 0.8 mm (0.032 in).
7. Armor
7.1 Material The standard armor should be made from a galvanized steel strip.
7.1.1 Size The thickness of the steel strip for round cable constructions, before galvanizing, should have a nominal thickness of 0.64 mm (0.025 in). The minimum wall thickness at any point should be no less than 0.56 mm (0.022 in). The thickness of the steel strip for flat cable constructions, before galvanizing, should have a nominal thickness of 0.51 mm (0.020 in). The minimum wall thickness at any point should be no less than 0.43 mm (0.017 in). The typical width of the steel strip is 12.7 mm (0.500 in) and should be no more than 19.1 (0.750 in) mm before forming.
7.1.2 Coating The steel strip should be zinc-coated after slitting. The coating should be applied to all surfaces by the hot- dip galvanizing process.
7.1.3 Tensile strength and elongation The zinc-coated strip should have a tensile strength of not less than 275 MPa (40 000 psi) elongation of not less than 10% in 25 cm (10 in). All tests should be performed in accordance with applicable portions of ANSI/NEMA WC 71/ICEA S‐96‐659, before application of the strip to the cable.
7.1.4 Weight of zinc coating The weight of zinc coating should be determined before application of the strip to the cable. The strip should have a minimum coating weight of 110 g/m 2 (0.35 oz/ft 2 ) of exposed surface. The weight of the coating should be determined in accordance with the method described in ASTM A90. The zinc-coated strip should not exceed the bare-metal strip thickness by more than 20% at any point.
.1.5 Adherence of coating The zinc coating should remain adherent without flaking or spalling when tested in accordance with applicable portions of ANSI/NEMA WC 71/ICEA S‐96‐659. 7.1.6 Armor for harsh environments Thicker steel strip can be provided. Heavier Type II galvanizing may be used as per ASTM A90. For extremely corrosive environments, stainless steel (316L) or other metal alloys are available.
7.2 Construction
7.2.1 Round cable
The armor strip should be applied over the cable core with sufficient tightness to compress the jacket splines to provide sufficient mechanical strength to maintain the integrity of the cable in vertical installation. The strip should be helically applied and formed in such a manner as to be interlocked. The armor should withstand a seven times overall diameter bend radius without separation of adjacent turns.
7.2.2 Flat cable The construction should consist of the three-phase conductors laid in parallel. The armor strip should be applied over the insulated conductors with sufficient tightness to fit snugly. The armor strip should be helically wrapped and formed in an overlapped manner. The assembly should withstand a bend that is seven times the major axis of the cable. The armor overlap should not open up between adjacent turns. The direction of bend should be in the normal direction of cable spooling.
8. Manufacturer’s electrical test requirements
8.1 Conductor testing Before application of any covering, conductors should be tested to meet the physical requirements of Clause 3 of this recommended practice.IEEE 1018 pdf download.
