Our standard dry-type transformers are manufactured to meet the requirements of international standards (IEC). Design according to other national standards (ANSI, etc.) is available upon request.
Our standard dry-type transformers have a winding concept of vacuum Cast-Resin and/or VPI (vacuum pressure impregnated). Our standard dry-type transformers are IP00 protected and AN cooled and normally equipped with an off-circuit voltage regulation of +/-2x2.5% by the use of bolted links.
The energy losses are standardized to; normal and low losses. Other specific requirements in terms of energy losses can be achieved with our customized design.
The level of accessories and monitoring equipment is limited to such types that can be fitted to the standard design.
With our customized design are we flexible to meet various special requirements. These transformers will be made to order and handled as an individual project to be sure that all specific requirements are met.
We can offer the VPE (vacuum pressure encapsulated) winding concept with multiple coating of silicone resin for better environmental protection or the RESIBLOC concept for extreme installation and operation conditions.
The customization process covers everything from both electrical and mechanical design parameters to the level of accessories and instrumentation. This gives us the possibility to meet special customer requirements in respect of operation as well as for instance installation in places with space restrictions.
