600A connector accommodates multiple cables

The Elastimold ComboT Integral Separable Connectors’ simplicity reduces installation time and the risk of costly installation errors.

Elastimold ComboT Integral Separable Connectors accommodates multiple cables in one connector, providing the shortest elbow stack height in the industry. And, it eliminates the need to modify or replace entire enclosures.

As loads grow in underground distribution systems, so does the necessity to connect two underground power cables to one common connection point within existing switchgear. Most of these connections use two 600A T-body elbows stacked one behind the other, which occupies more space in the switchgear cabinet. Often, there is not enough space to accommodate the additional connectors, which leads to costly modifications to the switchgear cabinet and vault, if not replacement.

“The new Elastimold ComboT Integral Separable Connectors save about three inches of space in switchgear cabinets by connecting multiple cables with one piece,” said Chad Smith, director, product management for Thomas & Betts. “Utilities can make use of the full capacity of existing gear without being limited by connection clearance.”

An additional benefit is more operating clearance for linemen in vaults, which makes installation safer and more effective. The connectors’ design, which features a simple system with fewer interfaces, eliminates blind assembly and minimizes the chance of cross threading. Using standard 600 or 900-series studs, it is installed with standard assembly tools. Its internal hex broach ensures the proper installation torque.

The connectors feature red provider backbone transport (PBT) interfaces for 15 kV reducing taps and blue for 25 kV reducing taps in compliance with IEEE 386. The 25-kV reducing taps are vented to prevent partial-vacuum flashover.
