The LZK series open type current transformer is suitable for current measurement, signal sampling, and microcomputer protection of electrical equipment in 35KV AC power systems. This current transformer has the characteristics of small size, light weight, openable, and easy installation. It is widely used in compact fully insulated ring network switchgear and is very suitable for forming a sampling unit with remote terminal devices such as RTU and FTU to provide data support for the entire system. During installation, simply clip it onto the connected incoming and outgoing cables, which is convenient and fast. It has been widely used in compact fully insulated ring network switchgear such as SafeRing/Plus, Uniswitch, RM6/SM6, SVS, GA/GE, FB, SS, and is also used in combination substations and cable distribution boxes.  

This type of current transformer uses high-quality imported silicon steel sheets with high magnetic permeability as the magnetic material, which has the characteristics of divisible core and low magnetic circuit loss. Its semi-circular core and secondary winding are vacuum cast with high-quality epoxy resin in a flame-retardant plastic shell, which is moisture-proof, stable in performance, and does not require maintenance. During installation, clamp two semi-circular rings onto the phase separated cable and secure them tightly with clamps. They are integrated with the cable in a harmonious and aesthetically pleasing manner and are suitable for 35KV cables ranging from 35mm2 to 400mm2. The clamps are made of high-quality stainless steel material, which is sturdy, reliable, and free of eddy currents.  

According to the different current conversion ratios, accuracy levels, and rated loads, this series of current transformers are divided into the following types, with specific parameters detailed in the corresponding parameter tables for each model. We can customize current transformers with different specifications and parameters according to user requirements.
