CID-01590: Elbow, Integral Seal, 200A, Loadbreak

Super-Class:
  200A, Loadbreak Seperable Cable Accessories
Class Name: Elbow, Integral Seal, 200A, Loadbreak
Sub-Classes:
Summary: Elbow, Integral Seal, 200A, Loadbreak

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.

The integral jacket seal provides a quick and easy means to sealing the cable jacket to prevent moisture ingress. The jacket seal is molded to the loadbreak elbow eliminating the need for separate cable sealing products. It can also be used with braided ground strap/bleeder wire for terminating Tape shielded cable.
