What is the problem?

Electrical Infrastructure is Too Big

Electrical distribution infrastructure like substations require an acre of space on average — space that comes at a premium in dense urban locations, where installation of critical infrastructure can take up to a decade.

Why is this equipment so large?

Problems Begin where the Cable Ends

Cables are extraordinarily dense electrical insulators; however, once broken, the internal electric field diverges, transforming the surrounding air into a critical (and unreliable) component of the insulation system.

What if we didn’t break the cable?

The Intelligent Cable Splice

The intelligent cable splice combines the flexibility and function of modern power electronics with the structure and materials of medium-voltage cables. The result is an inline power conversion technology that can be spliced directly between the power cables.

Infrastructure Anywhere There is a Cable

Storm Hardening

  • Outages due to weather cost the U.S. billions each year in economic impact. The intelligent cable splice is designed to be completely passively cooled and retrofittable in existing underground cable vaults, providing rapid storm hardening capability for utilty customers.

    • Passively cooled

    • Retrofit for cable vaults

Downhole

  • Harsh impacts and high temperatures make downhole power electronics challenging. The intelligent cable splice uses state of the art high-temperature components enabling operation in the harshest conditions.

    • High-density coaxial formfactor

    • High-temperature film capacitors, magnetics, and SiC modules

Datacenters

  • The intelligent cable splice provides high step-down ratios and high-density at medium voltage, enabling a first-of-its-kind indoor medium-voltage distributions system for power hungry AI datacenters. The medium-voltage is stepped down at the cabinet, enabling cabinets up to 1 MW.

    • High step-down ratios

    • High efficiency

    • High power density at medium-voltage

Charging Depots

  • Industrial EV depots concentrate massive charging demand, straining grid interconnections, land, and equipment. The intelligent cable splice helps shrink footprints and accelerate deployment, making large-scale charging more practical in space- and time-constrained sites.

    • Multi-mode operation

    • High Efficiency
