Summary: A separable connector (elbow) is a fully insulated and shielded system for terminating and electrically connecting an insulated power cable to electrical apparatus, other power cables, or both, so designed that the electrical connection can be readily established or broken by engaging or separating the connector at the operating inte rface. Suitable for use on 26.4 kV, 4-wire, solidly-grounded systems and 5 kV systems. Because of high fault duty, connectors rated 200 A continuous are not appropriate for network systems. Network systems should be constructed with connectors rated 600 A (or 900 A) continuous

Summary

The 200A loadbreak seperable elbow connector is suitable for connecting URD underground cable to URD transformers and switchgear. It provides a deadfront submersible cable connection. These elbows are submersible so they are especially useful in all subway and subsurface transformer primary connections, and connections to various types of equipment such as vacuum switch and interrupters.

Loadbreak and load make operations require the aid of a live-line tool (shotgun stick with elbow puller).

For application on ungrounded WYE or delta systems, the next higher voltage class product is recommended, for instance on a 15KV delta, the 25KV elbow should be used. Their ratings are always line-to-line, so a 15kV elbow will only be rated 8.6KV Line-to-Ground, so a 15kV delta will exceed the rating of the elbow.

The elbows kits are cable size sensitive due to the elbow lug needs to be crimped to the connector, and the elbow housing needs to provide a water tight seal around the cable insulation. [1] [2]

Note: the drawing shows an elbow with a jacket seal kit. This will prevent the ingress of moisture under the jacket which could cause corrosion of the neutral conductor.
