Product Description
LSZ one-piece three phase current transformer is suitable for installation in
the ring net switch cabinets and threephase casing on the main column
switch for the three phase current and zero sequence current measuring and
protection , also be used for more cablecircuit of zero sequence
current measurement and protection.
The series of zero sequence current transformer core and secondary windings
is made of high quality epoxy resin vacuum casting in the fire retardant plastic casing,
which has the characteristic of moisture proof, stable performance and dispensing with maintenance.
