LDZC-10 High Precision Current Transformer

LDZC-10/24/35 high-precision current transformer
General description

 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 main unit such as Safe Ring/Safe Plus, RM6/SM6, SVS, GA/GE, FB, SS and so on because of its small volume, light weight, and convenient installment.
 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 tables of every type.
