High Voltage Cable Accessories Innovation

TE Connectivity (TE) supports customers all over the world overcome daily challenges. Maintaining the service of a power line is one of them.

TE Offers Products that Keep the Power Flowing.

TE engineers and sales professionals helped a customer in Europe address a difficult application challenge. When it is necessary to connect different cable types and sizes, time is short, and the power must stay on, a solution that is ready-to-go is essential.   

The Challenge

A damaged cable was out of service, and the lead time for replacement was too long. The outage of the installation site had to be addressed immediately.

Since no similar cable was unavailable in stock, the utility had to find another alternative to connect several cables with different sizes and different construction to each other.

The Solution

TE was able to provide a readily available solution with the three-piece joint (EHVS-145T). The addition of the joint and the connector which goes into the kit made it possible to connect different types of cables and keep the power flowing. Thanks to this innovative solution, the utility easily and quickly repaired the line and the line was back in service.
