LZT one set of tube electric current mutual inductors

Sum up:

LZT suits of tube the intersection of electric current and mutual inductor suitable for, exchange the intersection of 35kV and switch, the intersection of case and the intersection of person who become and electric current, electric energy of apparatus, 10kV- of power system, measure with the computer protecting. This electric current mutual inductor installs the telescopic root of the apparatus of becoming in switch, case etc., have characteristic such as being small, light, easy to install, have already employed in electric equipment such as compact ring network switch cupboards, condensers,etc. extensively.

Become than the difference that, accurate grade and amount supported according to the electric current, this serial mutual inductors are divided as the following types, the concrete parameter sees every parameter table with corresponding type.
