Choose between copper or aluminum bushings, mineral or PCB-free oil, and enjoy peace of mind with a rustproof, painted exterior.

Durability and Low Maintenance

With an anticipated lifespan exceeding 25 years (under normal conditions) and efficiency up to 99%, this transformer is built for long-term, low-maintenance operation. ONAN cooling and a noise level below 58 dB contribute to a safer, quieter, and more reliable installationmaking it well-suited for environments with strict regulations or proximity to residences.

FAQs of Corrugation Wall Transformer:

Q: How does the Corrugation Wall Transformer ensure safe and reliable operation?

A: The transformer is equipped with safety accessories like a Buchholz relay, oil level gauge, and conservator tank to promptly respond to faults or abnormal conditions. Coupled with its robust insulation (Class A or F), high protection grade (IP23+), and rustproof finish, it guarantees operational safety and longevity even in demanding environments.

Q: What environments are suitable for installing this transformer?

A: Designed for both indoor and outdoor setups, the transformer can be pad- or pole-mounted, tolerates ambient humidity up to 95%, and operates reliably at altitudes up to 1000 meters above sea level. Its rustproof finish and protection against dust and moisture make it ideal for varied climatic and industrial conditions.

Q: When should I opt for mineral oil versus PCB-free oil in this transformer?

A: Mineral oil is a standard insulating medium offering excellent cooling and dielectric properties, suitable for most applications. PCB-free oil is recommended when environmental safety is a primary concern, as it is non-toxic and environmentally friendly, meeting modern regulations and sustainability requirements.

Q: Where is the transformer manufactured and can it be exported?

A: This transformer is expertly manufactured in India, adhering to international (IEC 60076) and national (IS 1180) standards. As a leading exporter and supplier, we deliver to global markets, ensuring customization and compliance with client-specific requirements.

Q: What advantages does the ONAN (Oil Natural Air Natural) cooling type offer?

A: ONAN cooling provides efficient heat dissipation without the need for forced cooling, resulting in quieter operation and reduced maintenance. This makes the transformer reliable for continuous service, even where minimal supervision or mechanical infrastructure is available.

Q: How does the transformers customizable coil connections benefit power systems?

A: With options like Dyn11 and Yyn0 or customized winding connections, the transformer offers versatility to support various network configurations. These options help optimize phase displacement, voltage regulation, and harmonics suppression, adapting to distinct power distribution requirements.
