Outdoor Split-core Current Transformer. GFUVE LZCK series, outdoor split-core current transformer, provide either 1A or 5A output and are designed to monitor outdoor conductors in distribution transformer monitoring.The product design for these outdoor current transformers is such that they can convert an AC input current of up to 5000A amperes into an output of 5A or 1A depending on customer requirements.LZCK-80 outdoor current transformers are applicable for AC power system 35kV and measurement of current of power supply equipment below 10KV also can be used for microcomputer protection. This type of current transformer employs imported silicon steel which with high permeability as magnetic material, has the characteristics of Small magnetic circuit loss and can be split, its semicircular core and secondary windings employ high quality epoxy resin vacuum, casting in plastic-case (ABS&PC) which is flame retardance anti-moisture, stable performance, no maintenance. LZCK-80 Class 0.5s 10VA 10m outdoor cable.
