หม้อแปลง LZC High-Precision Cutreent

LDZC high precision current transformer is suitable for current measurement and protection of distribution equipments in 35KV and 10KV AC power system. It is widely used in compact fully insulated ring net switchgears such as Safering/SafePlus, RM6/SVS, GA/GE, PB, SS and so on because of its small volume, light weight, and convenient installment.

It is very convenient that the transformer can be directly installed an connected output and input cables.

New magnetic material is taken to be the core of the 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 is 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 vacuum poured by high quality epoxies resin in the fire retardant plastic casing, which has the characteristic of moisture proof, stable performance and dispensing with maintenance. The cable can cross the current transformer through its internal poles quickly and uniformly.

The current transformers can be divided several kinds according to the various current ratio, accuracy and rated loads. The specific parameters are showed in the corresponding parameter table of every type.
All kinds of current transformer of different specification and parameters can be made according to the client's demands.
