本指南涵盖了在指定额定电压为5至35 kV的缩径挤压绝缘屏蔽电力电缆时应考虑的设计变量。除设计变量外，本指南还包括在使用缩径电缆时应考虑的预防措施，包括缩径对电缆附件的影响。无论何时，当考虑将直径减小的电缆作为按照行业标准设计的电缆的替代品时，都必须咨询电缆和电缆附件制造商。

This guide covers the design variables that should be considered when specifying reduced diameter extruded dielectric shielded power cables rated 5 through 35 kV. In addition to design variables, this guide includes precautions that should be considered if reduced diameter cables are going to be utilized, including the effect of reduced diameters on cable accessories. It is imperative that both cable and cable accessory manufacturers be consulted whenever a reduced diameter cable is being considered as a substitute for cable designed to industry standard.
