Medium voltage dry-type transformers

1. Product Overview

SCB series 10 kV transformers, manufactured using epoxy resin casting, are energy-saving transformers. They utilize vacuum epoxy resin casting technology and multi-layer cylindrical foil winding. Due to their oil-free, fire-resistant, fire-safe, and environmentally friendly characteristics, they are widely used in urban power grids, commercial buildings, factories, hospitals, subways, data centers, and other locations with high requirements for safety, fire protection, and energy efficiency.

With stable operation and easy maintenance, they are one of the core components of medium and low voltage distribution networks.

2. Model Meaning

High efficiency and energy saving

Rated voltage: 10 kV class (high voltage 10 kV, low voltage typically 0.4 kV)

3. Main Advantages

1. High efficiency and energy saving. By adopting a low-loss Class 11 design, the no-load loss and load loss significantly exceed national standards, greatly saving electricity and reducing operating costs. The low no-load current reduces reactive power loss, improves the power factor, and reduces investment in reactive power compensation.

2. Safe and fire-resistant design. Oil-free construction with fire-resistant epoxy coating. Self-extinguishing, non-flammable, with no risk of fire, explosion, or oil leakage. It can be installed in distribution panels, basements, and densely populated areas, meeting fire safety regulations.

3. Eco-friendly and moisture-resistant. No odor or toxic gas emissions during operation. High moisture resistance, mold resistance, salt spray resistance, and pollution resistance, capable of normal operation at 100% relative humidity. Can be restarted without pre-drying after shutdown, suitable for humid and coastal areas.

4. Reliable operation. Windings are manufactured using vacuum casting, ensuring high mechanical strength, resistance to sudden short circuits and lightning strikes. Partial discharge is extremely low (≤10 pC), insulation performance is excellent, and service life exceeds 20 years.

5. Low noise level and easy maintenance. Optimized magnetic circuit design ensures low noise (50–60 dB(A)). Compact design, small size, light weight, and easy installation. Requires no or minimal maintenance. Equipped with an intelligent temperature controller for overheat alarm, protection activation, and automatic fan control. RS485 communication is available for remote monitoring.
