Undersea Power

Spellman High Voltage is the leading independent supplier of Power Feed Equipment to the Telecom industry. Our land-based, shipborne, and portable power feed equipment (PFE) is used to power submarine fiber optic cable repeaters for telecommunications shore stations, during cable laying and repair operations. 

LAND (PFE-HV and PFE-LV):  5kV up to 18kV systems are deployed around the globe depend on Spellman's high reliability, redundancy and robust PFE systems for maximum uptime. Systems are available that provide a full spectrum of continuous power for both short and long cable run needs. 

SEA (PFE-SB): 6kV up to 20kV systems are installed on many of the major cable laying ships around the world, becoming the preferred choice of cable shipbuilders and owners. The latest generation of shipborne power feed equipment now features electronic polarity reversal. 

PORTABLE (PFE-P): 4kV and 6kV versions provides the consistent, reliable, and safe high voltage power in a compact footprint. The PFE-P incorporates the same advanced digital management system as Spellman's Shipborne PFE.
