Three Phase Dry Type Mv Hv Transformers 10KV Distribution Transformer Low Loss

The SCB11 Series 10kV Dry-Type Transformer is an advanced power distribution solution engineered for environments where fire safety and environmental protection are paramount. Unlike oil-filled units, the SCB11 uses epoxy cast resin technology to encapsulate the windings, making it virtually non-flammable and self-extinguishing.

This "Dry-Type" design is ideal for indoor installations, especially in high-density areas such as commercial complexes, data centers, airports, and underground subways. Rated for 10kV / 11kV networks, the SCB11 provides high mechanical strength, excellent short-circuit resistance, and a significantly lower environmental footprint.

• Vacuum Cast Resin Insulation: High-voltage windings are cast in a vacuum using thin layers of pure epoxy resin. This process eliminates partial discharge and ensures the coils are completely moisture-proof and dust-proof.

• Superior Fire Safety: The resin materials used are flame-retardant and self-extinguishing. In the event of an external fire, the transformer will not release toxic gases or explode, meeting the highest fire safety standards (F1 rating).

• Low Loss & High Efficiency: The SCB11 series utilizes high-quality cold-rolled grain-oriented (CRGO) silicon steel cores, resulting in significantly lower no-load losses and noise levels compared to the older SCB10 models.

• Strong Short-Circuit Withstand: Fiberglass reinforcement in the resin gives the coils exceptional mechanical rigidity, allowing them to withstand the thermal and mechanical stresses of sudden short circuits.

• Maintenance-Free Operation: With no oil to leak, test, or replace, the SCB11 requires only periodic visual inspections and cleaning, significantly reducing the Total Cost of Ownership (TCO).

1. Commercial Real Estate: High-rise office buildings, shopping malls, and hotels where oil-filled equipment is restricted due to fire codes.

2. Public Infrastructure: Subway stations, airports, and tunnels where safety and space-saving are critical.

3. Data Centers: Providing stable power with high reliability and zero risk of oil contamination for sensitive server environments.

4. Industrial Clean Rooms: Pharmaceutical and semiconductor plants that require clean, non-polluting power equipment.

• Temperature Control System: Every unit is equipped with a digital temperature controller (PT100 sensors) that provides real-time monitoring and controls the automatic cooling fans (AF) to prevent overheating.

• Enhanced Overload Capacity: When equipped with forced-air cooling (AF), our transformers can operate at 120%–130% of their rated load for short durations, perfect for handling peak demand.

• Eco-Friendly & Recyclable: At the end of its 30-year service life, the materials (copper and steel) are easily recoverable, and the resin does not contaminate soil or groundwater.

• Custom Enclosures: We provide optional IP20 or IP23 protective cabinets in steel or stainless steel to prevent accidental contact and protect against dripping water.

Q: Can this transformer be installed outdoors?

A: Dry-type transformers are primarily designed for indoor use. If outdoor installation is required, they must be housed in a specialized IP44 (or higher) weather-proof enclosure.

Q: What is the noise level of a 200kVA SCB11?

A: Our SCB11 units are designed for ultra-low noise. A 200kVA unit typically operates below 45–50 dB, making it quiet enough for installation near residential or office areas.

Q: Does the cast resin crack over time?

A: No. We use a specialized epoxy resin with a thermal expansion coefficient similar to the copper/aluminum windings. This prevent cracking during the heating and cooling cycles of normal operation.

◆The high-voltage winding is made of enamelled copper wire, and the low-voltage winding is made of copper foil. The high voltage winding is filled with glass fiber felt and poured by imported epoxy resin without filler in vacuum state. After curing, it forms a solid whole with high mechanical strength, less partial discharge and high reliability.

◆Flame retardant, explosion-proof,non-polluting, environmental friendly, can be installed in the load center.

◆The coil does not absorb moisture,the iron core, the clamp after special processing can be in 100% relative humidity and other harsh environment operation.Discontinuous operation without tide treatment.

◆ Short circuit resistance,high lightning impact level,strong overload capacity.
