A new generation of IEEE Class F, 155ºC /165ºC NEMA GPO- 1 material. H755 is designed to bridge the gap between 130ºC Class B GPO-1 materials and Class H 180ºC grades. H755 has quickly gained recognition in the industry as a high performance material at a similar cost as standard GPO-1. H755 has been successfully sealed tube tested for compatibility in a number of high voltage 220ºC U.L. recognized insulation systems (UL File #E83907 Systems HRP- HV1 and HRP- HV2). There are numerous applications in transformers and motors where a Class F material is required or performance upgrade without cost penalty is desirable. Standard color - Ivory. Meets Gov't Specs - LP-509, I-24768/6.
