Product Description

DAHU electrical specializes in the production of 0.5-40.5kv transformers. It has cooperated with many national power bureaus for 10 years and exported to foreign markets. If there is any quality problem within the warranty period, it can be replaced free of charge.The protection level information of LZZBJ9-10A current transformer is as follows:

Rated insulation level: 12/42/75kV. This means that the transformer can withstand an industrial frequency withstand voltage of 42kV and a lightning impulse withstand voltage (full wave) of 75kV.

Rated dynamic stabilizing current and rated short-time thermal current: According to different combinations of accuracy levels, the rated dynamic stabilizing current (peak) and rated short-time thermal current (RMS) of LZZBJ9-10A current transformer have different values. For example, for 0.2S/0.5/10P10 level, the rated dynamic stabilizing current is 15kA (peak), and the rated short-time thermal current is 90I1n (RMS).

Filth level: The filth level is class II, indicating that the transformer is suitable for a certain degree of pollution environment.

Altitude: The transformer is suitable for use at altitudes up to 2000 meters above sea level.

These protection level parameters are essential to ensure the safe and reliable operation of the LZZBJ9-10A current transformer in the power system. They indicate the maximum voltage level that the transformer can withstand, as well as its stability performance under specific conditions.
