SynTherm® – Insulating Materials SynTherm® YT56 (metastar® YT56)
SynTherm® YT56 is a synthetic medium density electro-insulation paper constructed of a calendered, aromatic polyamide fibride flock composition.
SynTherm® YT56 is a Class H (180 °C) insulating material. Its mechanical, thermal and electrical properties are between SynTherm® YT510 and SynTherm® YT511.
Temperatures over 200 °C only slightly influence its electrical properties. The good mechanical properties can be extrapolated to significantly higher temperatures. SynTherm® YT56 is also suitable for use at temperatures to -190 °C due to its polymer-structure.
It has a high short-term dielectric strength. SynTherm® YT56 is compatible with all classes of common resins, varnishes, adhesives as well as transformer liquids, lubricants, and cooling agents. Common solvents may lead to slight reversible moisture expansion. SynTherm® YT56 has low flammability (UL 94V-0) and very high resistance to beta and gamma radiation.
Application
SynTherm® YT56 is designed for cost critical applications which require a moderate mechanical and electrical strength. Application ranges from phase insulation in AC and DC motors to layer insulation in wet and dry transformers and chokes, even exposed to beta and gamma radiation.
