6.3 Month and year of manufacture
The month and year of manufacture shall be induded among the package markings described in Clause 6.2 or shall be included among the product markings described in Clause 6.1. The use of a code shall be allowed.
7 Deep-well submersible water pump cable
The construction of deep-well submersible water pump cable shall Consist of assemblies comprising two or more insulated rcuit conductors having a wet rating, and an optional insulated equipment grounding conductor, with or without an overall jacket. These cables shall be of the twisted or parallel configuration with the option of having a low temperature rating of —40C.
Circuit conductors shall consist of solid or stranded 2.08 — 33.6 mm2 (14 — 2 AWG) copper, solid or stranded 3.31 — 33.6 mm2 (12 — 2 AWG) aluminum ACM, or stranded 42.4 — 253 mm2 (1 AWG — 500 kcmil) copper or aluminum ACM. The optional insulated equipment-grounding conductor shall be of the same construction as the circuit conductor, and of a size that is not smaller than indicated in Table 29, except that a copper equipment-grounding conductor shall be allowed with aluminum circuit conductors, as described in Table 29. An aluminum equipment-grounding conductor shall be allowed with copper circuit conductors, as described in Table 30. All of the conductors shall comply with Clause 4.1.
Insulated conductors of the types listed in Groups I, II. and Ill of Table 31, assemblies a), b), and d) of Clause 7.2.3, shall comply with the requirements of Clauses I — 6 of this Standard. Insulated conductors of the types listed in Groups I and Ill, assembly C), shall have an integral insuIationjacket consisting of the sum of the thickness of insulation of Table 10 corresponding to the types listed, plus the thickness of integral jacket from Table 32,
The insulation and integral jacket shall be of the same compound as the listed product and shall comply with the applicable requirements of Clauses 1 — 6. and the assembly shall comply with the requirements of Clause 7.4.
Polyethylene-insulated conductors of Group IV. assembly d) of Clause 7.2,3 shall be insulated with unfilled polyethylene and shall comply with Tables 33 and 34 and the applicable test methods of this Standard.
The conductors shall be assembled in one of the following ways:
a) CABLED WITH OVERALL JACKET: this cable assembly has two or more Insulated circuit conductors from Group I, II, Ill, or IV of Table 31 and shall be cabled together with an optional insulated equipment-grounding conductor in either a right- or left-hand lay of unspecified length. with an overall jacket. The jacket shall comply with the thickness requirements of Table 35 and the physical properties specified ri Table 37.
b) CABLED WITHOUT OVERALL JACKET: this cable assembly has from two to six insulated circuit conductors from Group I of Table 31 with an individual jacket in accordance with Table 32. or from Group Ill of Table 31. and shall be cabled together helically with an optional insulated equipment-grounding conductor in either a right- or left-hand lay of unspecified length. without an overall jacket.
C) PARALLEL WITH INTEGRAL WEB WITHOUT OVERALL JACKET: this cable assembly has two, three, or four cirouit conductors from Group I of Table 31 with an integral jacket from Table 32. or from Group Ill of Table 31. together with any optional equipment- grounding conductor laid parallel on the same axis. The conductors are joined to one another with an interconnecting web. The conductor insulation, or integral insulation, and jacket shall be extruded simultaneously with the interconnecting web and shall be of the same compound. The minimum thickness of insulation at any point on any conductor, after separation, shall not be less than required for the specified wire type.
