Why Transformer Selection Matters for Businesses distribution Transformers serve as a cornerstone in electrical distribution for numerous commercial establishments, facilitating the transfer of electricity across multiple circuits and powering equipment essential for various applications. In sectors like manufacturing, even a brief period of downtime can result in substantial financial losses, highlighting the critical need for a reliable energy source. Industries such as manufacturing and commerce demand a delicate balance between efficiency and cost-effectiveness to remain profitable. Opting for the right transformer plays a pivotal role in achieving this equilibrium. While it may seem tempting to cut costs by choosing a cheaper option initially, investing in a high-quality, dependable transformer tailored to your requirements proves to be a more economical decision in the long run.

ADVANTAGES OF PAD-MOUNTED TRANSFORMERS Pad-mounted transformers emerge as a versatile and efficient solution within the domain of electrical distribution, offering a myriad of advantages tailored to address the diverse requirements of contemporary electrical infrastructure. Let’s delve into these benefits. 1. Safety Measures Pad-mounted transformers prioritize safety in their design. Enclosed structures shield live components, substantially mitigating the risk of electric shock. Moreover, they often integrate fault protection mechanisms that swiftly detect and isolate issues, averting potential dangers and ensuring the safety of both the public and maintenance personnel. 2. Compact design Renowned for their sleek, compact design, pad-mounted transformers seamlessly blend into various surroundings, unlike other transformer types. Manufacturers have the capacity to tailor exteriors to harmonize with local landscapes or urban settings, minimizing visual disruption and preserving t

Harmonic tolerance: When the dry-type transformer is fully loaded, it should work safely and reliably under the superposition of harmonic current of 10% of its rated current.

Step-up substation is designed as box type and specially for new energy generation industry, which can adjust the low voltage from inverter station to high voltage and then run in power grid. So a box-type inverter station and a step-up station can be integrated into one power generation station. It’s widely applied in Solar Energy Power Plant, Wind Energy Power Plant and Nuclear Power Plant, etc.

Varelen manufactures cast resin dry type transformers power up to 25 MVA and with voltage up to 36 kV. Our factory has both technology “cast resin ” and “vacuum pressure impregnation” which are used in manufacturing. offers a cast resin transformers production with copper and aluminium windings and the option of embedding with a Class F or Class H (180°C) system. The partial discharge parameter that specifies the transformer lifetime is <5 pC in our dry type transformers. As an advanced power equipment, dry-type transformerhas many advantages in the context of energy transformation, and provides important support for sustainable energy development and stable operation of power system.

To avoid overheating, efficient transformer cooling is particularly important. This is all the more important because rising ambient temperatures and dynamic load curves, which go hand in hand with an increasing proportion of renewable energies, also make the operating conditions for transformers more demanding. In order to achieve a better cooling capacity, natural cooling is increased by means of increased air mass flow through fans. Varelen team designed a oil immersed transformer with 2 fans, cooling way KNAN, standard  IEC60076, Beyond the direct energy savings, the use of cooling fans promotes environmental sustainability. A well-cooled transformer operates efficiently, reducing overall energy consumption and minimizing the carbon footprint associated with power distribution.

Green and environmental protection: with environmental protection as the design concept, the transformer is pollution-free during use, no maintenance, and has flame retardant and fireproof characteristics, providing an ideal energy conversion solution for the construction of clean and safe photovoltaic power generation system.
