Electric utilities and cable manufacturers share the goal of ensuring cost effective, safe, and reliable cable for the delivery of power to the ultimate customer (the utility ratepayer). This goal can be achieved through fostering a spirit of cooperation and understanding. This user specification provides additional methods to help ensure that power cables system will meet the purchasing quality assurance and performance needs of the electric utility industry.
This specification applies to high-pressure pipe-type impregnated paper insulated and laminated paper polypropylene insulated cables for use in the transmission of electrical energy. It describes the various choices that an engineer must consider when specifying paper-insulated cables designed for operation under either liquid or gas pressure for utility use. In addition, both types of cables are intended for operation at a nominal pressure of 200 psig (1400 kPa).
