Product description
Product Overview
The 252kV Current Transformer is designed for extra-high-voltage power systems and transmission substations. It converts primary current into standardized secondary current for metering, protection relays, and control systems with high accuracy and stability.
This product is widely used in EHV substations, transmission corridors, and grid interconnection systems where higher insulation level and electrical reliability are required. It is engineered to operate safely under high electrical stress, pollution, and extreme weather conditions.
Key Features of 252kV Current Transformer
Extra-High Voltage Measurement Stability
Provides accurate current transformation in 252kV transmission networks with excellent linearity and stability.
Enhanced Insulation Design
Designed for EHV systems with reinforced insulation structure to withstand lightning impulse and switching surge.
Heavy-Duty Outdoor Performance
Suitable for harsh substation environments with strong resistance to pollution, humidity, and temperature variation.
Advantages of 252kV Current Transformer Compared with Other Voltage Levels
Designed for EHV Transmission Systems
Compared with 126kV CT, the 252kV model is used in extra-high-voltage grids with higher insulation requirements and stricter grid standards.
Higher System Security Margin
Offers stronger dielectric strength and improved reliability for long-distance transmission and grid interconnection projects.
FAQ – 252kV Current Transformer
1. What is the typical lead time for a 252kV Current Transformer?
