Special current transformer for ring network cabinet

Open current transformer is suitable for current measurement and microcomputer protection of power supply equipment below 35KV and 10KV in AC power system. This current transformer has the characteristics of small size, light weight, openable and easy installation. In the network switch cabinet, it is directly stuck on the connected incoming and outgoing cables during installation, which is simple and fast. It has been widely used in compact fully insulated ring network switchgear, and is also used in combined substations and cable distribution boxes.
This type of current transformer uses high-quality imported silicon steel sheet with high magnetic permeability as the magnetic material. It has the characteristics of divisible iron core and small magnetic circuit loss. Its semi-circular iron core and secondary winding are made of high-quality epoxy resin. Vacuum casted in a flame-retardant plastic shell, moisture-proof, stable performance, and maintenance-free.

During installation, clamp the two semi-circular rings on the split-phase cable, and hold them tightly with a hoop. Three elastic rubber rings are against the cable and the cable is integrated, which is harmonious and beautiful. The 10KV and 35KV cables of 35㎜2-400㎜2 are both can apply. According to the difference of current transformation ratio, accuracy level and rated load, this series of Current transformers are divided into the following types. For details, please refer to the parameter table corresponding to each model.
