35kV Cast Resin Dry-Type Transformer SCB10 Series up to 6300kVA

Key Structural Features of 35kV Epoxy Resin Cast Dry-Type Transformer

Fire Safety & Environmental Protection
Epoxy resin cast construction ensures self-extinguishing properties, making the transformer safe for installation in fire-sensitive areas. No risk of oil leakage, fully environmentally friendly.

Low Loss & High Efficiency
Optimized core and winding design results in low no-load and load losses, reducing operational costs over the transformer’s lifetime.

Low Noise Level
Special core structure and resin encapsulation significantly reduce operational noise, suitable for noise-sensitive environments.

High Reliability
Thousands of units in service demonstrate performance reaching international reliability standards.

Excellent Moisture Resistance
Can operate normally in 100% humidity conditions. Requires no pre-drying before restarting after shutdown.

Maintenance-Free
No oil or cooling medium required. Minimal maintenance reduces total cost of ownership.

Structural Characteristics

Core
High-permeability grain-oriented cold-rolled silicon steel.

45° full miter multi-step core joints.

Square tube pull-rod structure with core column bound by insulating tape.

Special resin coating on core surface prevents rust and moisture ingress.

Effectively reduces no-load loss, excitation current, and noise.

Windings (Foil-Wound Low Voltage Coils)
Low voltage windings use full-section copper foil with Class F insulation.

Wound on dedicated foil winding machines for uniform ampere-turn distribution.

Eliminates issues such as high short-circuit stress, poor heat dissipation, and welding inconsistencies found in traditional wire-wound coils.

Coil ends are resin-sealed and cured for enhanced moisture and contamination protection.

Temperature Control System
Equipped with BWDK series digital temperature controller.

Temperature sensors embedded in the upper part of each low voltage coil.

Provides automatic three-phase temperature monitoring, display, over-temperature alarm, and trip functions.
