The LDC-10 high-precision current transformer is suitable for current measurement, energy metering and microcomputer protection of 10kV power supply and consumption equipment in AC power systems. The current transformer has the characteristics of small size, light weight and convenient installation. It has been widely used in compact fully insulated ring main switchgear such as SafeRing/Plus, Uniswitch, RM6/SM6, SVS, GA/GE, FB, SS, FTR and other series. This type of current transformer uses new magnetic conductive materials as the core of the measuring winding. Its high magnetic permeability, low saturation magnetic induction intensity and excellent stability ensure high measurement accuracy and low instrument security factor. High-quality imported silicon steel sheets processed by advanced technology are used as the core of the protection winding, ensuring a high accuracy limit factor. The toroidal 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 maintenance-free. This type of current transformer is small in size, light in weight, and occupies little space. It is fixed in the cable chamber of the ring main switchgear. During installation, only the cable needs to pass through the inner hole, which is simple, fast, harmonious and beautiful.
