Description
1k107 China Nanocrystalline Toroidal Transformer Core
Product Description
Features:    
         
   High permeability - greatly improved transformer accuracy and reduce difference and angular than the difference 
   Light weight, low cost - the price was significantly lower than permalloy, cost-effective  
   Excellent temperature stability - can be -55 - 130 ºC to work long hours  
   Saturation magnetic flux density between silicon steel and Permalloy between - is conducive to reducing the instrument security factor
     
Application areas:    
   Measuring Current Transformer Substation Core (accuracy 0.5-0.01 grade, rated voltage 0.5-500kv) 
   Power transformer is specifically measure current and power transmission lines of special transformers. According to measurement accuracy class requirements, can choose a different soft magnetic materials as core. The higher permeability core, the higher the measurement accuracy. At present the greatest amount of core material is cold-rolled silicon steel, glass and nano-crystalline alloy Mo alloy. In recent years, high-precision level (such as the 0.2, 0.2S class, 0.5S level) of the transformer demand is increasing rapidly. When asked to become more than a small, low-security turns, or the core size due to volume requirements restricted circumstances, the cold-rolled silicon steel sheets often do not meet the required precision. Although the high permeability glassy Mo alloys meet the required precision, but the price higher. The use of nano-crystalline core can not only meet the required accuracy and the price lower than the glassy Mo alloys.
