Tsty Dry Type Rectifier Transformer for Electroplating Plant DC Power Supply and Harmonic Mitigation

Product Description

Product Description

TSTY Dry Type Transformer – Safe, Quiet and Maintenance Free Indoor Power Solution

The TSTY dry type transformer (cast resin type) is a three phase, air cooled power transformer designed for indoor installation where fire safety, low noise and zero maintenance are critical. Unlike oil immersed transformers, our dry type units contain no liquid coolant, eliminating the risk of leakage, fire spread or environmental contamination. With epoxy resin encapsulated windings, these transformers offer excellent dielectric strength, moisture resistance and thermal stability. They are widely used in commercial buildings, public facilities, renewable energy systems, and industrial plants where safety and reliability cannot be compromised.

Specification

Key Applications

High Rise Buildings & Commercial Complexes – Power supply for elevators, HVAC, lighting and emergency systems in skyscrapers, shopping malls, hotels and office towers.
Hospitals & Medical Facilities – Clean, fire safe power distribution for operating rooms, imaging equipment, intensive care units and life support systems.
Data Centers & Telecommunication Hubs – Reliable voltage regulation for servers, cooling systems and UPS backup, with ultra low noise to meet strict environmental standards.
Airports & Railway Stations – Step up or step down for baggage handling, signaling, lighting and passenger information systems, ensuring continuous operation.
Tunnels & Subways – Flame retardant, low smoke, zero halogen (LSZH) compliant design for underground infrastructure.
Renewable Energy – Step up transformer for commercial rooftop solar (480V to 10kV/35kV) and small wind turbines, installed inside buildings or outdoor enclosures.
Industrial Plants – Power supply for textile mills, food processing, chemical plants and mining facilities where oil leakage is prohibited.
Marine & Offshore Platforms – VPI (vacuum pressure impregnated) versions resistant to salt spray, vibration and humidity.

Technical Features

Epoxy Cast Resin Encapsulation – High voltage and low voltage windings are fully encapsulated under vacuum with epoxy resin, providing excellent insulation, moisture protection and mechanical strength.
Fireproof & Self Extinguishing – Class F or H insulation, self extinguishing on flame removal, no fire load – ideal for densely populated or high value areas.
Low Noise Operation – Noise level typically below 55dB (depending on capacity), compliant with strict urban environmental requirements.
Zero Maintenance – No oil checks, no leak detection, no routine maintenance – just periodic visual inspection and cleaning.
Low Loss & High Efficiency – Available in SCB10, SCB11, SCB13 and SCB18 series. Amorphous alloy core option reduces no-load loss by 30–50% compared to conventional silicon steel.
High Short Circuit Strength – Rigid epoxy casting and advanced clamping structure ensure exceptional mechanical and dielectric strength.
Flexible Cooling – Natural air (AN) standard; forced air (AF) with integrated fans for higher overload capacity.
Customizable – Any vector group (Dyn11, Yyn0, etc.), tap changer (off-circuit), enclosure rating (IP20 indoor, IP23 drip proof, IP54 outdoor upon request).
Remote Monitoring – Optional temperature sensors (PT100) and digital display for winding temperature; RS485/Modbus communication available.

FAQ

FAQ

1. What international certifications do TSTY dry type transformers hold?
TSTY dry type transformers are certified to IEC 60076, IEEE C57, CE, UL (available upon request), GOST, and ISO9001/14001/45001. Our CNAS-accredited testing laboratory performs full routine and type tests to ensure compliance with global standards, facilitating smooth customs clearance and grid acceptance worldwide.

 
2. Can you customize transformers according to my drawings or technical specifications?
Yes, we offer full customization. You can specify voltage rating, capacity, vector group (e.g., Dyn11, Yyn0), tap changer (off-circuit or on-load / OLTC), cooling method (ONAN, ONAF, OFAF), winding material (copper or aluminum), core material (amorphous alloy or grain-oriented silicon steel), enclosure protection (IP54, IP68), and any required accessories. We will produce an optimized design based on your drawings or project requirements.

 
3. What is your typical lead time for TSTY dry type transformers?
For standard products, the lead time is approximately 20–25 days from order confirmation. For customized units, the lead time depends on the complexity of the design, special materials, and testing requirements – our sales team will provide a confirmed schedule upon order placement.
