Product Description
LZCT723-10 CHINA HIGH QUALITY HIGH VOLTAGE BUSHING TYPE CURRENT TRANSFORMER
LZCT series China high quality high voltage bushing type current transformer is suitable forcurrent measurement and microcomputer protection of electrical equipment in 10KV,35KV and 110KV AC power system.It is widely used in compact fully insulated ring network switchgears such as ABB-Safe Ring/Safe Plus...and cable distribution boxes.The transformer can be directly installed at the inlet andoutlet cables.The slice is imported silicon material. Thesemicircular ring core and secondary windings arevacuum poured by insulated resin.
P1, P2 is primary polarity terminal, S1, S2 is secondary polarity terminal.
P2, S2 is homonymous terminals (subtractive polarity).
