F895NH roving has good electrical insulation performance, CTI≥600, halogen-free flame retardant; It has good mechanical properties at 180℃. It is mainly used for mechanical, electrical applications and is suitable for H class motor, transformer, carbon brush bracket, rail locomotive and other insulating structural parts.
Product Advantages
Halogen-Free Flame Retardant × High Safety:
Utilizes a halogen-free epoxy resin system that releases no harmful gases during combustion, complying with EU RoHS/REACH environmental directives. Ideal for applications with stringent environmental requirements, such as rail transit and new energy sectors.
H-Class Temperature Resistance × High-Temperature Stability:
Withstands long-term exposure to 180°C while maintaining exceptional mechanical strength and insulation performance in high-temperature environments like motors and transformers. Features a low thermal expansion coefficient (≤5×10⁻⁵/°C) and outstanding resistance to thermal shock.
Superior Electrical Insulation:
CTI value ≥600V, far exceeding conventional insulating materials (e.g., standard epoxy boards with CTI ~200–400V), effectively preventing surface leakage and arc discharge to ensure safe operation of high-voltage equipment.
Product Applications
Class H Motors and Transformers:
Used for motor winding insulation, slot wedges, and end supports, capable of withstanding 180°C high temperatures and high-frequency electromagnetic vibrations; transformer insulation barriers and supports meet high insulation and flame-retardant requirements.
Rail Transit Traction Systems:
Serving as insulation barriers and carbon brush holders for traction converter motors, resistant to high-frequency vibrations, extreme temperature fluctuations, and high-voltage environments. Already applied in multiple vehicle models of CRRC Group.
High-Voltage Power Transmission Equipment:
Manufactured as insulation baseplates for high-voltage switches and insulator frameworks, isolating high-voltage conduction while providing mechanical support, suitable for ultra-high-voltage DC transmission projects.
New Energy Sector:
Insulation components for wind power converters and support parts for photovoltaic inverters, featuring high-temperature resistance, anti-aging properties, and environmental friendliness, compliant with "dual-carbon" policy requirements.
