SGB Gravity Line stands out for its high reliability even under deteriorated environmental conditions, long service life and, thanks to efficient production, also favorable economic conditions.
Dry-type transformer Gravity Line DTTHZ2N 250/10
Description
The Gravity Line from SGB-SMIT includes various models and power classifications of cast resin transformers that can be used for a wide range of standard applications.
The Gravity Line benefits from a particularly efficient winding system that allows to pass on the cost benefits of production directly to customers. At the same time, you can rely on SGB's proven quality and superior operation thanks to features such as fully vacuum-encapsulated high-voltage winding.
By keeping our engineering and development teams in house, we have short lead time from development to efficient production, to delivery of the finished transformer to the customer. Standardized procedures allow us to offer the Gravity Line as a particularly cost-effective transformer solution, though custom solutions such as harmonic components or specific requirements for accessories or transformer dimensions are also possible.
