A, use

This type of current transformer is an indoor device, used for current, energy, electricity and measurement in ac lines with frequency of 50-60Hz, 0.66kV and below.

Second, the structure of

This type of current transformer is bus type with annular iron core. The quadratic line is evenly distributed on the core; The insulation is made of resin casting insulation and formed by casting once.

Three, main technical indicators
