LMCK185-10 IP65 waterproof split core outdoor current transformer
The model LMCK185-10 series outdoor split core ct are applicable for AC power system 35kV and measurement of current of power supply equipment below 10KV also can be used for microcomputer protection. And the Transformer is compatible with distribution transformer monitor and provides high quality power parameter quality signal for the monitor to control, measure and monitor the energy quality and so on in grid system.
The LMCK185-10 split core current transformer applies to the outdoor electric power system with frequency 50Hz or 60Hz, its ingress protection is IP67. This type of current transformer employs 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 or PC) which is high accuracy, ultraviolet-proof and explosion-proof, fire-proof, maintenance-free, stable and reliable performance, easy installation, etc.
All of our current transformers are strictly comply IEC60044-1, IEC 61869-2, NTC 2205, GB1208-2006, ANSI/IEEE C57.13.
