Insulation for motors and generators

ABB offers insulation materials for motors and generators. Our flexible insulation materials are used in electrical machines for layer insulation, slot insulation, slot closure and layer insulation. Their high mechanical resistance and special surface properties (including significantly decreased friction) enable automated processing to be performed optimally at the customer's premises.

Our multi-layer flexible laminates Pucaro Press-span, Pucaro Triflexil® and Pucaro Ecoflexil®, made from pressboard, polyester and polyamide films, polyester non-woven material or aramide papers, fulfil the requirements of automated processing. All flexible electrical insulation materials are available in rolls, strips and sheets.
