Common Insulation Materials Used in the Renewable Energy Generation and Energy Storage Industries
Insulation materials used in renewable energy generation systems (including solar photovoltaic power, wind power, hydropower, and thermal power generation) and Energy Storage Systems (ESS) can be classified into several categories based on their material structure and application functions, including laminated insulation materials, flexible insulation materials, transformer insulation materials, molded insulation materials, and other specialized insulation materials.
Classification of Insulation Materials for Renewable Energy Generation and Energy Storage
| Material Category | Typical Materials | Key Features | Typical Applications |
| Laminated Insulation Materials | FR-4, G10, G11, GPO-3, Phenolic Paper Laminate, Phenolic Cotton Cloth Laminate | High mechanical strength, excellent electrical insulation | ESS PCS, inverters, switchgear, generators |
| Flexible Insulation Materials | DMD, NMN, NHN, AMA, Polyimide Film (PI), PET Film | Flexible, high thermal class | Motor windings, battery modules |
| Aramid Insulation Materials | Nomex Paper, Nomex Laminates | Excellent heat resistance and aging resistance | Wind generators, dry-type transformers |
| Transformer Insulation Materials | Pressboard, Crepe Paper, Crepe Paper Tube, Laminated Wood | Oil-resistant, high mechanical strength | Step-up transformers, power transformers |
| Molded Insulation Materials | SMC, DMC | Excellent molding properties, flame retardant | Combiner boxes, switchgear, energy storage cabinets |
