Introduction This introduction is not part of IEEE Std 386-2006, IEEE Standard for Separable Insulated Connector Systems for Power Distribution Systems Above 600 V. This standard was developed in response to a need created
7、by the rapid expansion of underground distribution systems. A key element that allowed this expansion to become a reality is the separable insulated connector. This device provides for simple and inexpensive connection and switching to transformers and other equipment used in underground distributio
8、n. When separable insulated connectors became available, the Institute of Electrical and Electronics Engineers (IEEE) and the National Electrical Manufacturers Association (NEMA) worked cooperatively to develop a document that defined the interfaces, ratings, and test conditions for the device. The
9、success of that cooperative effort is apparent from both the vast number of these devices now in interchangeable use in the field and their enviable safety record. This cooperative effort continues due to the ongoing upgrading and changing nature of these underground systems and products. The recent
10、 cooperative effort has been provided by the ANSI C119.2 Subcommittee and the IEEE Working Group on Separable Connectors under the auspices of the Insulated Conductors Committee of the IEEE Power Engineering Society. This revision reflects the following major additions: Definitions of new and previo
