3. Definitions
The following definitions are the intended meanings of terms used in this standard or assodated with separable insulated connectors systems. Figures 1 and 2 show typical components of separable insulated connectors. The term connector as used in this standard means separable insulated connector.
bushing insert. A connector component intended for insertion into a bushing well (see Fig 1).
bushing well. An apparatus bushing having a cavity for insertion of a connector component, such as a bushing insert (see Fig 1).
continuous current rating. The designated rms alterrating or direct current which the connector can carry continuously under specified conditions.
dead-break connector. A connector designed to be separated and engaged on deenergized circuits only.
elbow. A connector component for connecting a power cable to a bushing, so designed that when assembled with the bushing, the axes of the cable and bushing are perpendicular (see Fig 1).
environmental temperature. The temperature of the surrunding medium, such as air, water, and earth, into which the heat of the connector is dissipated directly, including the effect of heat dissipation from associated cables and apparatus.
fault-closure current rating. The designated rms fault current which a load-break connector can close under specified ground bushing. An accessory device designed to electrically ground and mechanically seal a de-energized power cable terminated with an elbow.
grounding elbow. An accessory device designed to electrically ground and mechanically seal a bushing insert, or integral bushing.
hold-down bail. An externally mounted device designed to prevent separation at the operating interface of an elbow and an apparatus bushing.
insulated parking bushing. An accessory device designed to electrically insulate and shield and mechanically seal a power cable terminated with an elbow.
insulated cap. An accessory device designed to electrically Insulate and shield and mechanically seal a bushing insert or integral busling.
integral bushing. An apparatus bushing designed for use with another connector component, such as an elbow (see Fig 1).
