LVB series HV outdoor AC oil-insulated inverted current transformer meets all IEC and GB metering and protection classes (other standards on request). This current transformer has highly refined and processed oil/paper insulation system, high level of insulation, and good character of outside insulation. Also, it is light weight and requires very little oil.

LVB series current transformer has temporary protective winding, meets with big capacity of power system, and reclosing operation. Oil tank is made of corrosion-resistant materials, no maintenance outside.

Part Ⅰ: Operating Characteristics

Location: indoor or outdoor

Ambient temperature: -40℃ - +45℃ (Freezing field can meet -45℃)

Wind load: not exceed 35 m/s

Altitude: not exceed 3000m

Icing thickness: not exceed 10mm

Seismic strength: 8

Pollution level: lII or IV

Note: If the product using conditions beyond the above provisions, please contact us and we can solve as quick as possible.

Part Ⅱ: Demonstration of The Type

For example: type LVB-110W2 means that this CT gives extra the protection level winding for the inverted structure, may use in the Rated system voltage 100kV and can be used for pollution level Ⅲ area.

Part Ⅲ: Product Sectional View and Electrical Diagrams

Part Ⅳ: Products Design Features and Advantages

1. Highly refined and processed oil/paper insulation system and advanced technology, the electric strength of CT is improved obviously, guarantee the product operation reliability effectively.

2. The drive pipe which the company used has actually long creepage distance, the results of creepage distance/dry arcing di stance is rational. It improves the margin of the outer insulation resistance effectively, enhance pollution resistance.

3. Reasonable structure of the media and design, advanced technology which can make the dielectric loss (tan 6 ) reduced to below 0.5%, and steady in the long run.

4. Hight mechanical strength drive pipe and optimized structure design, it improves product mechanical strength.

5. Good seals and optimization structure, second terminal board using lead with epoxy resin conductive stem overall vacuum pouring parts, which can ensure do not produce oil leakage phenomenon.

6. Excellent seismic performance as a consequence of optimized designs of flanges, porcelain and their interconnection.

7. Lower dissipation, and steady in the long run.

8. Short primary conducting, Good Dynamic and Thermal Stability.
