The LCZK series of open type current transformers (also known as card type current transformers) are specifically designed for AC power systems with 10kV, 20kV, and 35kV ring main units, switches, combined substations, current measurement, and protection signal acquisition.
This type of current transformer uses high-quality imported ferrosilicon high permeability alloy or nickel iron high permeability alloy as the magnetic material. The product is openable, small in size, lightweight, and suitable for various complex installation environments, greatly improving the efficiency of secondary renovation projects. It is mainly suitable for cabinet types such as ABB's Safering and Safplus, Schneider's RM6 and SM6, Siemens' 8DJ and 8DH.
