LZZB1-35W OUTDOOR SUPPORT TYPE INSTRUMENT TRANSFORMERS

TECHNICAL DATA                               

current transformer of the type LZZB1-35W is casting resin and fully enclosed outdoor product. It is used for metering current and electric energy, relay protection in the electrical system of rated frequency 50Hz or 60Hz and rated voltage 35kV. The transformers can be executed according to the standards IEC44-1:1998 and GB1208-1997<Current transformer>.

III.Construction

The current transformer is fully enclosed. It is made by outdoor resin. The product has much merit such as electric arc resistances, ultraviolet ray and aging resistance long working time and etc. The primary and secondary windings and iron core are insulated by epoxy resin. It has a good ability of antipollution and moisture proof.
