H.V. CURRENT TRANSFORMERS

　
   Over 30 years of manufacturing experience of the H.V. current trans- formers, Nanjing Electric- ceramic Factory develops the new type-LB series current transformer on the base of analysing the domestic and foreign country goods' structure character and operating experience.
    The new type transformers are easy to operate, also with high reliability.
