Varelen oil filled power transformers can be in Utility networks, transport systems, industrial facilities, processing plants, tunnelling projects – everywhere a power supply is required.
In today’s energy-intensive environments, transformers play a crucial role in power management across various sectors. For industries that demand reliable and efficient power supply systems, choosing the right transformer type is key. A 3MVA Hermetic Sealed Conservator Type Transformer, designed as a medium voltage, three-phase transformer with a vector group configuration of Dyn11, brings optimized performance for a range of applications. Built to the IEC60076 and ANSI standards, this transformer is engineered for safe and efficient operations in Utility networks, transport systems, industrial facilities, and more. Varelen’s oil-immersed power transformers feature a robust copper winding and ONAN cooling for durable, compact, and high-performance energy solutions.
Hermetically sealed conservator type transformers are designed to keep air out, ensuring that the oil inside remains pure and free of moisture, which can otherwise lead to insulation breakdown over time. The hermetic sealing in these transformers prevents the oil from coming into contact with air, thus reducing oxidation and prolonging the life of the oil. By maintaining the oil's insulating properties, hermetically sealed transformers ensure improved reliability and reduced maintenance compared to non-sealed types.
Varelen’s hermetically sealed conservator type transformers are particularly well-suited for harsh environments where temperature fluctuations and dust can compromise other transformer types. These transformers come with a compact design that maintains efficiency and minimizes the footprint, making them a practical choice for space-constrained installations. The use of high-quality copper windings further enhances electrical conductivity and thermal stability, ensuring a safe and durable transformer solution.
The design of a 3MVA hermetic sealed conservator type transformer is focused on compactness and efficiency, which are critical for industrial applications. Varelen's transformers are engineered to optimize space without compromising on performance, making them suitable for limited-space installations. The compact design is complemented by precision-engineered copper windings, which minimize losses and improve the transformer's overall energy efficiency.
This efficiency is not only environmentally beneficial but also contributes to reduced operational costs over the transformer’s life. The hermetically sealed design also means fewer maintenance requirements, as it eliminates the need for regular oil inspections and top-ups, ensuring the transformer is always ready for operation.
ONAN (Oil Natural Air Natural) cooling is a highly efficient, low-maintenance cooling method ideal for medium voltage transformers. In this cooling system, the oil circulates naturally, dissipating heat as it moves through the transformer’s components, while the external air helps cool the oil further. This process keeps the transformer from overheating, enhancing its lifespan and ensuring continuous, safe operation.
Varelen’s ONAN cooling system is specifically designed to handle heavy loads and high temperatures without compromising performance. The absence of forced air or water circulation also means fewer moving parts, which reduces potential points of failure and minimizes maintenance needs. Additionally, the ONAN cooling method is cost-effective, as it reduces the need for auxiliary cooling systems and is suited for quiet operation in noise-sensitive areas.
Varelen specializes in custom oil-immersed transformers tailored to meet specific operational requirements. Every application has unique needs, whether it’s for utility networks, industrial facilities, or specialized processing plants. Varelen's oil-immersed transformers can be customized in terms of voltage rating, impedance, cooling method, and connection configuration, ensuring compatibility with existing systems and operational demands.
Oil-immersed transformers offer superior insulation and cooling compared to dry-type transformers. The oil acts as both an insulator and a cooling agent, allowing for higher power densities and making them suitable for large-scale applications. Varelen’s transformers are built to handle demanding conditions, providing both reliability and efficiency in power distribution systems.
Varelen's 3MVA hermetic sealed conservator type transformers are versatile enough to be used across a wide range of applications. From utility networks to industrial facilities and tunneling projects, these transformers offer reliable power supply solutions wherever they are installed. In processing plants and transport systems, where consistent power is crucial, these transformers ensure stable voltage levels and enhance the system’s overall reliability. The transformers are designed to withstand harsh operating conditions, including extreme temperature variations and humidity, making them suitable for both indoor and outdoor installations.
Copper windings provide several advantages for transformers, including higher electrical conductivity, improved thermal stability, and better overload tolerance. Varelen's transformers utilize premium-grade copper windings to minimize losses, thus enhancing energy efficiency. Copper's natural durability also improves the transformer's performance under heavy loads, helping it withstand extreme conditions and extend its operational life. Additionally, copper windings are less prone to corrosion compared to aluminum, making them ideal for critical and long-term installations where reliability is paramount.
Adhering to internationally recognized standards like IEC60076 and ANSI ensures that Varelen’s transformers meet stringent safety, reliability, and performance benchmarks. Compliance with these standards is essential for installations in regulated industries, as it guarantees that the transformer can perform safely under specified conditions.
