What is a Dead Break Elbow
Here refers to a cable connector, which is used to bridge AEIC or ICEA standard power cable in a stranded, compressed or compacted conductor to a pad mounted transformer,a switchboard or some other electrical equipment with bushings.
T-shaped dead break elbow is bolted onto a bushing insert through screwing a stud into the threads pre-assembled inside of the bushing insert. this means you can not pull it off freely to break the load and you have to unscrew the bolt & remove the T-body connector.
Except this dead break elbow, PowerTel is able to provide you other cable accessories, like load bread elbow, bushing inserts, stand-off bushings, load break junctions, elbow surge arrester a complete product chain to connect your pad mounted transformers properly, safely and reliably.

Load Break Elbow VS Dead Break Elbow
To be simply, when current flow in a power system less than 200 Amperage, a load break elbow can be used, while any power system over 200 or more amperage, a dead break elbow considered to be used.
One more important thing , In a radial feed system, people always have a right rating selection of this load break elbow connector and its associated bushing insert. however, in a loop feed system, people sometimes choose a wrong size of this dead break elbow to fit the bushing insert. The reason is that, in the first transformer in a loop feed system, it is requiring to carry all amperage in downstream transformers. At this situation, you have to choose a 600A or 900A rated dead break elbow & its appropriate bushing insert to support all current in the loop, based on the quantity of transformers in the loop.
