SynTherm® – Insulating Materials

SynTherm® YT510 (metastar® YT510)

SynTherm® YT510 is a synthetic electro-insulation paper constructed of a calandered, aromatic polyamide fibride flock composition.

Attributes

SynTherm® YT510 is a Class H (180 °C) insulating material. Temperatures below 200 °C only slightly influence its electrical properties. The excellent mechanical properties can be extrapolated at much higher temperatures. Due to the polymer structure, SynTherm® YT510 can also be used at temperatures as low as -190 °C.

It has a high short-time field intensity. SynTherm® YT510 is compatible with all common resin, varnish, adhesive classes, as well as transformer liquids, oils and refrigerants. Common solvents can result in easily reversible expansion. SynTherm® YT510 paper is flame resistant (UL 94V-0), moreover, it displays a very high level of beta and gamma-ray resistance.

Application

High quality SynTherm® YT510 is used in almost all known applications for electrical insulating materials. Application ranges from AC and DC motors to large generators, wet and dry transformers and chokes, even with beta and gamma radiation exposure.
