SynTherm® – Insulating Materials SynTherm® YT510 DDP
SynTherm® YT510 DDP is a synthetic electro-insulation paper constructed of a calandered, 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® YT510 is a Class H (180 °C) insulating material. Temperatures below 200 °C only slightly influence its electrical properties. The good mechanical properties can be extrapolated to significantly higher temperatures. SynTherm® YT510 is also suitable for us at temperatures to -190 °C due to its polymer-structure. It has a high short-term dielectric strength. SynTherm® YT510 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® YT510 has low flammability (UL 94V-0) and very high resistance to beta and gamma radiation.
Application
SynTherm® YT510 DDP is used as layer insulation in transformers.
