35kV Cast Resin Dry-Type Transformer

35kV Cast Resin Dry-Type Transformer Overview

This series is designed to step down 35kV grid power directly to 400V distribution voltage, or to other medium- and low-voltage levels for end users. Key advantages include:

• Reduced footprint and simplified multi-stage substation construction
• Lower project investment and improved economic efficiency
• Reduced 10kV transmission and transformation stages and low operation and maintenance costs
• High-voltage, low-current transmission instead of low-voltage, high-current transmission, reducing line losses and operating costs
• Direct 35kV supply to load centers, effectively improving power supply reliability

Product Features

The SC(B)10 series 35 kV dry-type transformers are low-loss, off-circuit tap-changing transformers designed in accordance with China standards.

• High performance and low losses
• Low-noise operation, achieved through high-quality silicon steel laminations and optimized flux density to reduce magnetostriction
• Enhanced impulse withstand capability, supported by optimized HV winding design and improved interlayer voltage and capacitance distribution; Optimized electric field distribution, contributing to lower partial discharge levels
• Optional temperature monitoring and forced-air cooling systems, with automatic fan operation under high-load conditions to improve overload capability
