NAME:LDK3-10 Splittable type current transformer
Detailed introduction:


The LDK series of split core-type current transformers are suitable for current measurement, signal sampling and microcomputer protection of electrical equipment in 10kV AC power systems. The current transformer has the following characteristics: small size, light weight, splittable and easy to install. It is widely used in compact full-insulation ring network switchgear, and is very suitable for RSU, FTU and other remote terminal equipment to form a sampling unit for the whole system data support. It is quick and easy to attach directly to the connected incoming and outgoing cable during installation. It has been widely used in compact full-insulation ring switchgear such as SafeRing/Plus, Uniswitch, RM6/SM6, SVS, GA/GE, FB, SS, etc. It is also used in combined substation and cable distribution box.
