0.66- 75kv high accuracy class 0.2 60hz current transformer export to many countries
The current transformer of type LCWD-36 is oil insulated and outdoor product. It is used for metering energy, current and relay protection in electric system up to rated frequency 50Hz or 60Hz and rated voltage 36kV.
The type of product has compact structure, small volume, lightweight and its body treated by drying vacuum. It is installed in the bushing filled with transformer oil.
The bushing's upper half-part is the primary winding and its dowen half part is the secondary winding. The primary winding's end is led from the two side of the cabinet's w all. It's staring terminal sign P1 is insulated with the wall by some little porcelain pipes and terminal signed P2 is directly connected with the wall. The front of the oil storage cabinet has some oil-dials showing different temperature and graduation.
1. Rated insulation level: 40.5/95/185kV;
2. Rated primary current: 5A;
3. Creepage distance of outside insulation: general type 735; W2 type 1100.
Note: If users have other special requirements, we may do some relevant adjustment to partial data.

LJ-75 Current Transformer
The LJ- 75 zero sequence current transformers are used in indoor environment, and provided for earthed electric systems of rated frequency of 50/60 Hz and rated voltage of 35kV and below. The relay DD-11/60 matches with this model. The products meet standards IEC60044-1 and GB1208-2006.
1. Ambient temperature: -5 ~40 ;
2. relative humidity: 85% or below at 20 ;
3. Altitude: 1000m;
4. Can be mounted in polluted indoor environment.
1. Because the primary main insulation is determined by the cable rather than the product itself, only the insulation level of secondary winding is tested. The secondary winding can withstand power frequency test voltage to earth of 3kV.
2. The sensitivity of the model of transformers complies with the following table.
The iron core is ring shaped and the secondary winding is wound around the core. The core is clamped by clip which has holes for installation
