LZZQB6-15 current transformers
Summary
The LZZQB6-15 current transformers are designed in 10kV and below AC systems of 50Hz or 60Hz for measuring and protection purposes. The products conform the standards IEC60044-1 and GB1208-2006.
Structure feature
The supporting type current transformers LZZQB6-15 are cast in epoxy resin insulated with big creepage distance and are excellent in anti-pollution and humidity protection. With high grade accuracy, it is suitable for protection against large short-circuit current.
