Cummins’ company makes global launch of S7 and S9 model ranges offering increased power densities at higher kVA ratings
Alternator manufacturer Stamford has launched two new products at the Middle East Electricity exhibition being held in Dubai.
The Cummins groups brand, which is a major alternator supplier on the global market, made the worldwide launch of its S7 and S9 alternator ranges on the first day of the show. Both new alternators were displayed publicly for the first time in the world at the exhibition.
According to Stamford, the S-Range programme was launched in 2016 “as a strategic initiative to reclaim market share in an increasingly competitive low kVA market”. The two new models answer the demands from the market for increased power densities further up the kVA range.
“Designed using CoreCooling Technologies, the Low Voltage S7 delivers high power density with continuous ratings up to 2.5MVA thanks to enhanced thermal management within the machine. This optimisation also helps reduce machine dimensions and weight,” said Scott Strudwick, director, global sales and marketing at Stamford.
The compact design benefits gives ease of integration into existing generating set designs, and brings with it upgraded Automatic Voltage Regulator options plus an overall design package that offers improved field serviceability, he added.
“The S9 is a High Voltage product that comes with true Class H insultation technology. Designed, tested and validated over an extended period in partnership with insulation material supplier Von Roll, at component, subsystem and at whole machine levels, this new system can run continuously at Class H ratings of up to 5,000kVA, 13.8kV, whilst still delivering high resistance to the mechanical and thermal stresses seen in rotating machine applications.”
The S9 product also offers both weight and dimensional reductions, ease of integration into existing generating set designs and improved field serviceability, he added.
The new Stamford S7 and S9 products also come with the company’s S-Range three-year warranty as standard.
