Product DescriptionIt is outdoor,single phase and organic insulation dry-type current transformer, which is used for metering and relay protection of 33-230kV,50 or 60Hz system.
Standards:
IEC 61869-1;IEC 61869-2
GB 20840.1; GB 20840.2
Product Features1. It is organic insulation type product.The external insulation is silicone rubber petticoat.
2. Electric field evenly distributed, small partial discharge and stable, small dielectric loss.
3. The current ratio can be adjusted easily by changing the wiring method at shielding enclosure through series or parallel connection.
4. The product has nooil, no ceramic, no gas, pollution-free.
5. Barely need for maintenance. Just need to measure capacitance and dielectric loss factor every 2~3 years.
6. The base uses spray painting or hot galvanizing, which gives a high degree of corrosion resistance.
7. Fasteners and nameplate are stainless steel.
