Description

Description
LVB-110W2 Oil-immersed Inverted Type Current Transformer is designed for 110kV high-voltage power systems. It is used to accurately transform primary current into standardized secondary current for metering, protection, and control applications. The inverted structure combined with oil-immersed insulation ensures enhanced reliability, safety, and long service life in outdoor environments.

Structural Features
The transformer adopts an inverted structure with the primary conductor located at the top and the secondary windings housed in the lower grounded tank, effectively reducing insulation stress. Combined with an oil-immersed and fully sealed design, it provides excellent dielectric performance, efficient heat dissipation, and high operational stability, ensuring reliable performance under harsh environmental conditions.

Applications
1.110kV high-voltage substations
2.Power transmission and distribution systems
3.Energy metering systems
4.Relay protection systems
