We are the exclusive agents for Moser-Glaser (MGC) in Sub-Saharan Africa, who are part of the Pfiffner Holding AG Group. MGC is based in Switzerland and was founded in 1914 boasting over 100 years in the field. MGC is a pioneer in Dry-type Transformer Bushing technology development for over 60 years, having invented DURESCA ®️ RIP technology in 1958.
In addition to a standard range, the design and production processes allow for flexibility and adaptability, meaning we are able to provide tailor-made solution for our clients. A key advantage of MGC Dry-Type Transformer Bushings is that they are simple to replace/retrofit with damaged and/or redundant Porcelain Bushings.
ADVANTAGES OF RIP &RIS:
• Maintenance free.
• Oil & gas tight system.
• No housing for oil end required.
• Non-inflammable.
• Operates with damaged housing temporarily.
• Core is fixed to flange.
• Excellent mechanical behaviour.
• Each mounting position allowed.
• Max. temperature < 120º C.
ADDED ADVANTAGES OF RIS:
• Lower Tan Delta.
• Not affected by humidity.
• No oil-paper ageing behaviour.
