Passive current transformer for relay protectionDetailed product description：

LZK-W passive relay protection current transformer is suitable for current and energy measurement and protection of power supply and consumption equipment in AC power systems below 35kV and 10kV. This transformer has the characteristics of small size, light weight, and easy installation, and has been widely used in compact fully insulated ring main units such as ABB and Schneider.

The LZK-W passive relay protection current transformer uses a new type of magnetic conductive material as the iron core for measuring the winding, which has high magnetic permeability and low saturation magnetic induction intensity, ensuring high measurement accuracy and low instrument security factor. High quality imported silicon steel sheets are processed by advanced technology to protect the winding iron core, ensuring a high accuracy coefficient.

The circular iron core and secondary winding are vacuum cast with high-quality epoxy resin in a flame-retardant shell, which is moisture-proof, stable in performance, and does not require maintenance. This type of current transformer has a small volume, light weight, and occupies small space. It is fixed in the cable room of the ring main unit and only needs to pass the cable through the inner hole during installation, which is simple, convenient, harmonious, and beautiful.
