Petrochemical dedicated enclosed transformer

Petrochemical dedicated enclosed transformer overview

Petrochemical dedicated enclosed transformer, different from ordinary oil immersed transformer, eliminates oil storage tank. The fin plate of the corrugated oil tank body serves as a heat dissipation and cooling element, and expands and contracts with the increase or decrease of the transformer oil volume, isolating the internal part of the transformer from the atmosphere, preventing oil deterioration and insulation moisture, and enhancing the reliability of operation.

The product adopts CAD design, and its performance meets IEC76.1-5 and CB1094.1-5 standards, and has passed ISO9001 quality system certification. This product has low noise, low loss, and three protection functions (moisture proof, mold proof, and salt spray proof), and can be widely used in harsh environments such as metallurgy, mining, and petrochemical. The high and low voltage casing and busbar of this product are protected by sealed boxes, and the connection part is equipped with interfaces. There are two options for users to choose from: cable entry and insulated busbar entry. It is equipped with a "telemetry" signal thermometer and pressure relay to enhance the reliability of the transformer.

Petrochemical dedicated enclosed transformer advantage

-High voltage copper wire winding technology to improve lightning resistance performance

-Low voltage foil winding technology, high-quality A-E grade insulation material insulation

-Low magnetic leakage, high mechanical strength, and strong short-circuit resistance

-The material of the iron core is high-quality cold-rolled grain oriented silicon steel sheets with mineral oxide insulation (from Baosteel and Wuhan Iron and Steel Group in China)

-By controlling the process of cutting and stacking silicon steel sheets, the loss level, no-load current, and noise are minimized

Petrochemical dedicated enclosed transformer FAQ

1. What is the primary application of petrochemical dedicated enclosed transformers?
   These transformers are designed for petrochemical plants, providing safe and reliable power distribution in hazardous, corrosive, or explosive environments.

2. What voltage levels do these transformers typically support?
   Common input voltages range from 6kV to 35kV, with output voltages such as 400V, 690V, or customized for specific petrochemical equipment needs.

3. What enclosure protection standards do these transformers meet?
   They usually comply with IP55 or higher for dust and water resistance, and some models feature explosion-proof (Ex d/e) certifications for Zone 1/2 hazardous areas.

4. Are these transformers oil-cooled or dry-type?
   Both options are available: oil-immersed for high efficiency or dry-type (resin-cast) for enhanced fire safety in critical zones.

5. How do these transformers handle corrosive environments?
   The enclosures are made of stainless steel or coated with anti-corrosion materials, and internal components are sealed to resist chemical vapors.

6. What safety features are included?
   Built-in protections include over-temperature alarms, pressure relief devices (for oil types), and surge arresters to prevent electrical failures.

7. Can they operate in high-temperature areas?
   Yes, they are designed for ambient temperatures up to 50°C (122°F) with optional cooling systems (fans or air conditioning).

8. Is remote monitoring supported?
   Optional IoT-enabled sensors can monitor load, temperature, and oil quality (if applicable), transmitting data to control systems.

9. What maintenance is required for enclosed transformers?
   Regular checks include insulation resistance tests, cooling system inspection, and enclosure integrity verification (annually or per operational conditions).

10. How do they comply with petrochemical industry standards?
    They adhere to IEC/EN 60076, IEEE C57.12.00, and may include ATEX/IECEx certifications for explosive atmospheres.
