Flyaford
High-dielectric standoff and busbar insulation components engineered for severe electrical stress, high-temperature stability, and zero-defect industrial operations.
As global energy infrastructure rapidly transitions toward decarbonization, high-density power electronics, and decentralized smart grids, the demand for electrical insulation components with enhanced mechanical toughness and superior thermal stability has skyrocketed. Traditional porcelain and glass standoff insulators—while historically prevalent—are increasingly exposed as single-point vulnerabilities in modern switchgear, energy storage cabinets (BESS), and electric vehicle (EV) charging architectures due to their inherent brittleness, vulnerability to micro-fracturing under mechanical vibration, and heavy mass.
CE-certified flexible composite insulators, synthesized from advanced thermosetting materials such as Bulk Molding Compound (BMC), Epoxy Molding Compound (EMC), and Phenolic Formaldehyde (PF) resins, represent a quantum leap in insulation technology. Designed to satisfy rigorous international electrical safety norms (IEC 60664-1, EN 60060-1), these composite standoff insulators integrate co-molded brass or steel hardware inserts within a glass-fiber-reinforced polymer matrix. The result is an insulating element that combines ultra-high dielectric strength (>25 kV/mm) with exceptional tensile, torsional, and flexural toughness.
In high-vibration applications—such as wind turbine nacelles, high-speed rail traction switchboards, and automotive energy systems—flexible composite insulators deform elastically under mechanical fatigue without micro-cracking. This structural resilience completely eliminates catastrophic dielectric breakdown, minimizing grid downtime and maintaining operational integrity across a thermal spectrum from -40°C up to +140°C.

Get technical clarity on CE certification, material selection, creepage distances, and custom OEM ordering procedures.
To obtain CE EU safety certification, our flexible composite insulators undergo rigorous compliance testing according to EN 60664-1 (Insulation coordination for equipment within low-voltage systems) and EN 60060-1 (High-voltage test techniques). Key evaluations include power frequency withstand voltage testing (0-100kV), lightning impulse withstand tests (up to 300kV peak), tracking resistance (CTI ≥ 600V), and thermal deformation analysis under full load. Compliance ensures safe deployment across all EU member states.
BMC (unsaturated polyester reinforced with short glass fibers) offers an outstanding balance of mechanical strength, high dielectric properties, UL94 V-0 flame retardancy, and exceptional cost-efficiency, making it the industry standard for low-to-medium voltage standoff insulators. EMC (epoxy molding compound) provides higher mechanical modulus, lower moisture absorption, and superior glass transition temperatures (Tg), making it preferred for specialized high-temperature automotive EV battery modules and ultra-compact switchgear applications.
Flyaford uses advanced direct compression co-molding, positioning precision-machined brass or zinc-plated steel inserts inside the molding cavity prior to high-pressure composite injection. This process chemically bonds and mechanically locks the metal insert within the thermosetting matrix. Unlike secondary glued inserts—which suffer from thermal expansion mismatch, adhesive degradation, and thread pull-out—co-molded inserts deliver up to 500 N·m torsional torque resistance and withstand severe thermal cycling from -40°C to +140°C.
