1. What Is a 200kVA Three Phase Oil Immersed Transformer?

A 200kVA three phase oil immersed transformer is a core power transmission device designed to convert high-voltage electricity into usable medium or low-voltage power for industrial and civil use. It operates on three-phase alternating current, ensuring balanced power distribution that meets the demands of large-scale equipment and multiple loads.

Lugao’s version serves two core functions:

• Voltage Conversion: Steps down high-voltage power from grids or generators to safe, usable levels for machinery, buildings, and infrastructure.
• Power Distribution: Delivers stable three-phase power to support continuous operation of industrial production lines, power grids, and public facilities.

The "oil immersed" design means the core and windings are fully submerged in high-grade insulating oil, which acts as both a cooling medium and insulation barrier. This structure is widely recognized for its reliability in outdoor and harsh environments, making it indispensable for power grid upgrades, industrial projects, and infrastructure development.

2. Core Advantages & Selling Points

High-Efficiency Operation, Lower Energy Loss

• Adopts high-quality cold-rolled silicon steel core and oxygen-free copper windings, reducing no-load loss by 15% compared to ordinary transformers.
• Advanced oil circulation and radiator design ensures rapid heat dissipation, maintaining operating efficiency above 98% even under full load.

Superior Safety & Long Service Life

• Fully sealed oil tank design prevents moisture, dust, and air from entering, avoiding oxidation and corrosion of internal components.
• Insulating oil provides excellent arc-extinguishing performance, with a pressure relief valve to release excess pressure, eliminating fire and explosion risks.
• Core components are treated with anti-corrosion and anti-aging processes, extending the service life to 20+ years with proper maintenance.

Strong Environmental Adaptability

• Operates stably in temperatures ranging from -30°C to +40°C, suitable for cold plateaus, hot deserts, and humid coastal areas.
• Complies with IP54 protection standards (optional IP55 upgrade), resisting dust, rain, and salt spray corrosion.
• Can work normally at altitudes below 1,000 meters, with customized solutions available for high-altitude projects.

Cost-Effective & Easy to Deploy

• Direct factory supply reduces procurement costs by 20-30% compared to distributors.
• Compact structure and reasonable weight (customizable according to transportation needs) simplify loading, unloading, and on-site installation.
• Minimum order quantity of 1 unit supports small-batch projects and trial purchases.
