kVA Strategies Awarded Cable Cleats for USS America
kVA Strategies was awarded the cable cleat contract from Northrop Grumman for the LHA-6, USS America. Throughout the evaluation
process, kVA Strategies worked closely with Northrop Grumman engineers and designers. The demanding qualification process
included passing the US Navy shock and vibration testing to validate the strength and reliability required to protect
the USS America's electrical infrastructure.
kVA Strategies provides the most reliable cable restraints to the electrical utility, oil & gas,
marine, petrochemical and industrial electrical markets.
Centaur Cable Saddle Revolutionizes HV Cable Support
The Centaur Cable Saddle is designed to support HV cables that are typically used in 69kV - 400kV electrical power transmission systems. The
Centaur Cable Saddle has been independently short circuit tested to IEC 61914 at 63kARMS/ 163kAPEAK for 1 second. Manufactured in
extruded marine-grade aluminum, Centaur Cable Saddles incorporate an integral low smoke and fume liner
to protect and cushion cables during short circuit conditions. For further details, refer to the Centaur Cable Saddle Data Sheet.
Cable Cleat Engineering Specification Updated
The engineering specification for cable cleats has been updated to reflect the requirements of the international cable cleat standard,
IEC 61914, as well as the National Electrical Code and Canadian Electrical Code. For a MS Word download, click on

International Standard for Cable Cleats
The International Standard IEC 61914:2009, Cable Cleats for Electrical Installations has been published. While this new International
Standard is based on the European standard EN 50368:2003, there are many enhancements, including
improved cable cleat testing criteria. The Founder and President of kVA Strategies, Charles A Darnell is the US Technical
Expert on IEC Subcommittee 23A that is responsible for preparing and maintaining the international cable cleat standard.
API RP14F Revises Cable Restraint Rules
The recently released fifth edition of API Recommended Practice 14F dated July 2008 (Design, Installation and Maintenance
of Electrical Systems for Fixed and Floating Offshore Petroleum Facilities)
paragraph 6.7.1.4 now requires cable restraints to prevent
excessive cable movement due to fault-current magnetic forces. The peer reviewed
consensus document further requires cable restraints be rated for the specific
cable size and available fault current and provides a formula for calculating
the mechanical forces between conductors during a short circuit. The
calculation tool enables engineers to evaluate the adequacy of cable restraints
in every application. API RP14F recommends fault-rated cable cleats as a
technique to prevent excessive movement of cable systems. These recommendations
align API RP14F with NFPA-70 (National Electrical Code), C22.1 (Canadian Electrical
Code) and other international codes, standards and recommended practices.
