本推荐规程确立了三芯圆形和扁平油井电缆的建议，该电缆由乙烯-丙烯橡胶（EPR）绝缘铜导线组成，用于向潜水泵电机提供三相交流电力。这些电缆还可能包括额外的覆盖层，包括根据机械和环境条件选择的包裹层、金属铠装或屏障和/或非金属护套或护套。

This recommended practice establishes recommendations for three-conductor round and flat oil-well cables consisting of ethylene-propylene rubber (EPR) insulated copper conductors used in supplying three-phase ac electric power to submersible pump motors. These cables may also include additional coverings consisting of wraps, metallic armor or barriers, and/or nonmetallic jackets or sheaths selected on the basis of mechanical and environmental conditions.
