SynTherm® – Insulating Materials SynTherm® YT56 DDP
SynTherm® YT56 DDP is a synthetic medium density electro insulation paper constructed of a calendered, aromatic polyamide fibride flock composition. Both sides of the paper are printed with a B-stage epoxy resin in a diamond dotted pattern.
The base material 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 DDP is designed for cost critical applications which require a moderate mechanical and electrical strength.
SynTherm® YT56 DDP is used as layer insulation in transformers.
Standards
- Insulating material class F (155 °C). Base material class H (180 °C)
- The base material is UL listed (RTI mech. + electr. 210 °C)
