Dry-type Current Transformers 
Products Explanation
Model: LGB

The dry-type current transformer, assembling by a bushing-type primary winding and secondary winding(s).Possessing those advantages of light frame, oil-free, gas-free, porcelain-free, fire-proof and explosion-proof etc, used for current measurement and relay protection in the power system with the rated voltage of *5kV.
 Technical Parameters

*Accuracy classes and their combinations: Steady accuracy classes are 0.2S, 0.2, 0.5S, 0.5, 5P, *0P, PR and PX; transient accuracy classes are TPS, TPX, TPY and TPZ. There are 1~6 pcs secondary winding(s) in a CT.
*Non-effectively earthed neutral system
Other parameters see the table:

 Main Features
The frame of the dry-type current transformer is upstanding, its parts which outside of the case are the bushing-type assemblies which made by silicon rubber umbrellas, and there are the primary terminal blocks at the top of the assemblies; The secondary winding(s) are going through the bushing-type primary winding, which put inside the case, there is a secondary terminals box in the obverse of the case; There are 4 pcs lifting eyebolts at the bottom of the case. The main insulation of the dry-type current transformer is made by the new organic composite materials, comparing to the other current transformers of the same voltage, it has the advantage of oil-free, gas-free, small volume, light and excellent performances.
