Undersea Power

Spellman's shipborne and land-based power feed equipment (PFE) is used to power submarine fiber optic cable repeaters for telecommunications shore stations and during cable laying and repair operations. We have become the leading supplier of Power Feed Equipment to the Submarine Telecom Industry.

Our shipborne power feed equipment (PFE) solutions have been installed on many of the major cable laying ships around the world, becoming the preferred choice of cable shipbuilders and owners for ship-borne power feed equipment. Land-based shore power installations around the globe rely on Spellman's high reliability, redundancy and robust PFE systems for maximum uptime. Together, they provide a full spectrum of continuous power for both your short and long cable run needs.

A typical shipborne power feed equipment (PFE) system provides up to 24kWatt capability with voltages up to 20kV. A full range of power feed equipment systems (PFE's) at various output power levels are available. Spellman also manufactures an active dummy load at output levels between 2kW and 40Kw - this can be included as part of the shipborne PFE suite.
