Ensuring Reliable Underground Electrical Grids

Reliable power supply is the backbone of the energy industry. Underground applications provide additional protection for electrical distribution infrastructure, and this is one way Utilities and business are working to maintain consistent operations. However, underground maintenance can be challenging, time-consuming, and usually require costly, excavation and system downtime. Cable accessories are critical in today’s complex underground power distribution system. If a single joint fails underground, it could lead to several hours of network downtime, high costs of maintenance and impact the near population.

While underground installation can bring a higher installation cost, the total cost of ownership is lowered with the right connections and proper installation training. As your partner we can supply highly engineered connections that will bring reliability to your network.

Pioneering Grid Reliability

We have a long history of innovation. We invented the triple layer tube for heat shrink joints to improve reliability and reduce installation time. Our switchgear connectors now integrate a partial discharge sensor, compatible with most grid monitoring devices to help you track your network performance and thereby reduce the frequency and duration of outages.
