وصف المنتج
Sturdy Seismic Resistant 1250 kVA 10/0.4kV Cast Resin Dry Type Distribution Transformer for Urban Rail Transit Auxiliary Power
Product Overview
This Sturdy Seismic Resistant 1250 kVA 10/0.4kV Cast Resin Dry Type Distribution Transformer is purpose-built for auxiliary power supply in urban rail transit systems, including metro stations, subway tunnels, light rail networks, and traction substations. It converts 10kV primary distribution voltage to 0.4kV secondary power, delivering reliable energy to station lighting, ventilation fans, escalators, signaling equipment, communication systems, and fire protection circuits.
The transformer features a three-phase epoxy resin cast coil construction that eliminates insulating oil entirely, achieving F1 fire behavior classification with inherently flame-retardant and self-extinguishing insulation materials. The core and coil assembly is designed and reinforced for seismic qualification, with anti-vibration mountings that dampen continuous operational vibration from passing trains while maintaining structural integrity under seismic events. Every unit is manufactured and tested in accordance with IEC 60076-11 and equivalent national standards, with routine test certificates provided for each delivery.
Key Highlights
- Sturdy seismic resistant construction with reinforced structural frame and anti-vibration damping ensures dependable operation under continuous train-induced vibration and seismic loading.
- Flame retardant and self-extinguishing cast resin insulation achieves F1 fire behavior classification with zero oil content, eliminating leakage and combustion risks in underground and confined rail transit spaces.
- Ultra-quiet operation with core and winding design optimized for low magnetostriction noise, meeting strict acoustic requirements of metro stations and underground equipment rooms.
- Moisture and dust resistant sealed coil construction enables reliable performance at 100 percent relative humidity and in tunnel environments with airborne particulates.
- Long service life exceeding 30 years under normal IEC 60076 loading conditions with minimal maintenance requirements, reducing total cost of ownership for transit authority asset management.

Urban Rail Transit Auxiliary Power Solution
Urban rail transit auxiliary power systems demand transformers that withstand continuous vibration, operate safely in fire-sensitive underground spaces, and deliver stable power to critical station loads around the clock. Our design addresses these conditions through specific technical measures.
Seismic and Vibration Resistance
Subway and light rail environments subject transformers to persistent low-frequency vibration from passing trains, as well as potential seismic events. Our structural design includes a reinforced steel core clamping frame with high-strength bolts, a base plate equipped with vibration-absorbing rubber pads or spring isolators, and glass fiber mesh reinforced coil encapsulation that prevents winding displacement under mechanical stress. These measures together achieve qualification per IEEE 693 seismic design recommendations for substation equipment, ensuring the transformer remains operational after seismic events.
Fire Safety for Underground Spaces
Underground metro stations and tunnel equipment rooms impose the most stringent fire safety requirements. The epoxy resin insulation system is a UL 94 V-0 rated material that does not propagate flames, emits very low smoke, and releases no toxic gases under extreme heat exposure. With zero insulating oil content, there is absolutely no risk of oil leakage, pool fire, or explosion, which are catastrophic failure modes in confined underground spaces where fire suppression is difficult and emergency evacuation is complex. The transformer achieves F1 fire behavior classification and meets the fire protection requirements of subway rail transit systems, including compatibility with NFPA 130 guidelines for fixed guideway transit and passenger rail fire safety.
Low Noise for Occupied Stations
Transformer noise in metro station equipment rooms must not intrude into passenger areas or adjacent commercial spaces. Our design controls magnetostriction through reduced magnetic flux density in the core, utilizes step lap joint construction at core joints to minimize localized flux concentration, and applies anti-vibration pads at all core to enclosure interfaces to interrupt structure-borne noise transmission paths. The resulting sound pressure levels of 50 to 54 dB(A) at one meter meet the acoustic requirements for occupied station environments.
Environmental Resilience in Tunnel Conditions
Subway tunnels and equipment rooms present conditions of high humidity, airborne dust and metallic particles, and temperature fluctuations throughout daily and seasonal cycles. The vacuum cast epoxy resin encapsulation seals the high voltage winding against moisture ingress, enabling the transformer to operate at 100 percent relative humidity and to restart without pre-drying after extended shutdowns. The C2 climatic class rating confirms suitability for transport and storage at temperatures down to -25°C, while the E2 environmental class rating certifies resistance to frequent condensation and heavy pollution.
Compact Footprint for Equipment Room Integration
Space in metro auxiliary equipment rooms is constrained. The cast resin transformer design achieves a smaller physical footprint compared to oil-immersed alternatives of equivalent rating. Bottom or side cable entry options provide flexibility for integration into existing substation layouts. For projects requiring prefabricated substation or containerized installation, we coordinate enclosure dimensions and ventilation requirements with the skid integrator to deliver a plug-and-play packaged solution.
Frequently Asked Questions
Has this transformer been seismically qualified for rail transit applications, and what standards apply?
Yes, it is built with a reinforced frame and anti-vibration mounts, with qualification per IEEE 693. Structural calculations and optional shake table test reports can be provided for project approval.
How does this dry type transformer meet fire safety codes for underground metro stations and tunnels?
The windings are fully encapsulated in flame-retardant epoxy resin with zero oil content, achieving F1 fire behavior. It emits minimal smoke and no toxic gases, meeting NFPA 130 guidelines for underground fire safety.
What noise levels can we expect in a metro station equipment room installation?
The transformer operates at 50 to 54 dB(A) at one meter. For quieter environments, we offer acoustic enclosures or reduced flux density core designs to further lower sound levels.
Can the transformer handle the cyclic loading pattern of metro auxiliary systems where ventilation, escalators, and lighting loads fluctuate throughout operating hours?
Yes, the Class H insulation with 100K temperature rise provides ample thermal margin. The foil wound low voltage winding absorbs load peaks from escalator starts and ventilation ramping without overheating.
What protection rating is recommended for a transformer installed in a tunnel equipment room with high humidity and dust?
IP23 stainless steel enclosure is the minimum recommendation for tunnel environments. Higher protection ratings and anti-corrosion treatments are available for the most severe conditions.
Is this transformer compliant with IEC 60076-11, and what testing and documentation does your company provide for EPC contractor acceptance?
Yes, every unit is tested per IEC 60076-11 and supplied with routine test reports. Type test data and third-party witness testing through KEMA, SGS, or Bureau Veritas are available upon request.
