The primary advantages of a 200 KVA, 11kV/433V, 3 Phase, 50 Hz, Aluminium Wound, Oil cooled Distribution Transformer are its lower initial cost and lighter weight due to the use of aluminium windings, combined with the efficient and cost-effective cooling and insulation properties of mineral oil.

 

Advantages of Aluminium Windings

The choice of aluminium for the windings provides specific economic and physical benefits:

• Lower Initial Cost: Aluminium is significantly less expensive and its market price is more stable than copper, which translates into a lower initial purchase price for the transformer.
• Lighter Weight: Aluminium is lighter than copper (approx. 3.3 times lighter by volume), making the overall transformer lighter and easier to transport, handle, and install, which is particularly beneficial for pole-mounted or outdoor applications.
• Good Heat Storage: Aluminium windings can store more heat for short durations during overload conditions compared to copper windings, which can be an advantage in certain industrial applications.
• Availability: Aluminium is widely available, ensuring a stable supply for manufacturing.

 

Advantages of Oil Cooling

The oil cooling mechanism offers excellent thermal management and insulation properties for reliable performance:

• Superior Cooling Efficiency: The transformer oil (typically mineral oil) is a highly effective coolant and dielectric medium. It circulates naturally to draw heat away from the core and windings, transferring it to the cooling fins or radiators to dissipate into the atmosphere.
• Excellent Insulation: The oil provides a high dielectric strength, enhancing the insulation between windings and preventing short circuits, which contributes to overall safety and reliability.
• Arc Quenching: The oil also acts as an arc-quenching medium, which is a key safety feature that helps suppress arcing events inside the tank.
• Longer Lifespan & Durability: Effective cooling helps slow down the degradation of the internal insulation components, contributing to a longer operational life for the transformer (often 25 years or more with proper maintenance).
• Noise Reduction: The oil helps dampen the mechanical vibrations of the core and windings, resulting in lower operational noise levels compared to some dry-type alternatives.
• Outdoor Suitability: Oil-cooled transformers are well-suited for outdoor use due to their robust, anti-corrosive coated tank designs, which protect internal components from harsh weather conditions and moisture.
