High Performance 11KV Cast Epoxy Resin ZCT Zero Sequence Current Transformer


LZCT722-10 bushing type current transformer is suitable forcurrent measurement and microcomputer protection of electrical equipment in 10KV and 35KV AC power system. It is not only widely used in compact fully insulated ring net switch cabinets and load switch cabinet but also cable distribution boxes because of its small size, light weight, open feasibility and convenient. It is very convenient that the transformer can be directly installed at connected output and input cables.


New magnetic material amorphous alloy or permalloy is taken to be the core of the bushing type current transformer, which has high magnetic permeability, low saturation induction density and good stability. Therefore, the measuring accuracy is higher and the instrument security factor in lower. Since the high quality silicon steel sheet metal processed by advanced technology is taken to be the core of the protection windings, the accuracy limit factor will be higher.


The circular ring core and secondary windings are poured by quality epoxies resin or polyurethane or silicon rubber in the fire retardant plastic casing, which has the characteristic of moisture proof, stable performance and dispensing with maintenance. The cable can cross the bushing type current transformer through its internal poles quickly and uniformly.
