 LZZBJ9-10C(1,2,5) current transformer

Description and meaning of model

LAABJ9-10C type current transformer is epoxy resin cast indoor total working conditions of the strut.Protection or energy measurment with the power system with rated frequency 50Hz rated voltage of 10kV and below.Which LZZBJ9-10C mounted in switch cabinets or other types of switchgear.

Characteristic of structure

The current transformer is the pillar structire.Closed casting with epoxy resin,resistant to pollution and humidity.Also suitable for the tropics.The transformer does not require special maintenance,just on a regular basis to remove surface dirt.Current transformer with epoxy pouring full-closed,small size,quailty,suitable for any location,installed in any direction.

C size parameters of the transformer.Only is the product of the length,width change.Height,one outlet terminals size remains unchanged.C1,C2 primary current are 5~3150A.

Technical Data

1.Rated insulation level 12/42/75kV(surface condensation and artificial class II filthy conditions)

2.the load power factor 0.8lag

3.Rated secondary current of 5A

4.product standard:GB1208 the

5.Safety factor:FS<10

6.Surface creepage distance:to meet the gradeII pollution class requirements

7.Other parameters see table below
