Product Description

Product Description:

The Oil Immersed Distribution Transformer is a vital component in the power distribution network, designed to efficiently step down high voltage electricity to a usable lower voltage for residential, commercial, and industrial applications. This transformer is specifically engineered for power distribution in both urban and rural areas, ensuring reliable and stable electricity supply across diverse environments. With a power rating ranging from 30 KVA to 1600 KVA, it caters to a wide spectrum of energy requirements, making it an ideal choice for various electrical distribution systems.

One of the standout features of this transformer is its Oil Cooled Distribution Transformer design. The transformer is oil immersed, meaning the core and coil assembly are submerged in high-quality insulating oil. This oil serves as both an insulator and a coolant, effectively dissipating the heat generated during operation. The cooling method employed is ONAN (Oil Natural Air Natural), where the heat is naturally transferred from the oil to the transformer tank and then to the surrounding air without the need for external cooling devices. This natural cooling system ensures efficient thermal management, prolonging the transformer’s lifespan and maintaining optimal performance under varying load conditions.

Constructed with durability in mind, the transformer tank is made from mild steel, which provides robust mechanical protection. Additionally, it is coated with corrosion-resistant paint to safeguard against environmental factors such as moisture, dust, and pollutants, which are common in both urban and rural settings. This corrosion resistance ensures the longevity of the transformer, reducing maintenance costs and downtime.

As an Oil Filled Power Transformer, it meets stringent safety and operational standards. The insulating oil not only prevents electrical faults by insulating internal components but also acts as a medium to detect potential issues such as overheating or oil contamination. Regular monitoring and maintenance of the oil condition further enhance the operational reliability of the transformer.

The Oil Cooled Distribution Transformer is designed with user convenience and reliability in mind. It comes with a warranty period of 1 year, providing assurance of its quality and performance. This warranty reflects the manufacturer’s confidence in the product’s durability and efficient operation under standard conditions.

In summary, the Oil Immersed Distribution Transformer is an essential asset for power distribution networks, especially suited for urban and rural applications. Its ONAN cooling method, combined with a robust mild steel tank with corrosion-resistant paint, ensures efficient, reliable, and long-lasting performance. The wide power rating range from 30 to 1600 KVA makes it versatile for various electrical demands, and the 1-year warranty offers peace of mind to users. Whether for new installations or upgrading existing infrastructure, this Oil Filled Power Transformer is engineered to deliver superior performance and dependable service in the field of power distribution.

Packing and Shipping:

Product Packaging and Shipping for Oil Immersed Distribution Transformer

The Oil Immersed Distribution Transformer is carefully packaged to ensure safe delivery and protection during transportation. The transformer is first coated with a protective rust-preventive oil to safeguard all metal surfaces. Then, it is securely placed inside a sturdy wooden crate designed to withstand rough handling and environmental conditions.

Inside the crate, the transformer is cushioned with high-quality packing materials such as foam, bubble wrap, or wooden braces to prevent any movement or impact damage. All accessories and documentation are packed separately but securely within the crate.

For shipping, the packaged transformer is loaded using appropriate lifting equipment to avoid any mechanical damage. It may be transported via road, sea, or rail depending on the destination, ensuring compliance with all relevant transportation regulations and safety standards.

Upon arrival, customers are advised to inspect the packaging for any signs of damage before unloading. Proper storage and handling instructions should be followed to maintain the transformer's integrity until installation.
