Flyaford
Precision-engineered BMC/DMC low and medium-voltage busbar supports certified to CE, UL, and RoHS standards.
Established in 2007 in the Jinyi New District of Jinhua City, Zhejiang Province, ZHEJIANG FLYAFORD ELECTRON CO., LTD. has grown into an international OEM/ODM powerhouse specializing in the R&D, precision formulation, compression molding, and technical sales of high-performance electrical insulators and thermosetting composite accessories.
Operating a state-of-the-art 35,000 square meter smart manufacturing plant, Flyaford houses over 60 advanced compression molding presses and 20+ automated testing facilities. With a daily production capacity exceeding 200,000 pieces and an ultra-rigorous quality assurance protocol maintaining a defect rate strictly below 100 PPM, we provide critical dielectric protection components to world-leading OEM manufacturers in green energy, electric transportation, grid infrastructure, and industrial automation.
How macro-trends in electrification, green grids, and high-power electronics are driving revolution in dielectric composite materials.
Global environmental regulations (such as EU F-gas rules) are forcing power equipment OEMs to phase out Sulfur Hexafluoride (SF6). This transition requires solid dielectric insulation components made of Bulk Molding Compounds (BMC) and Epoxy Molding Compounds (EMC) with exceptional partial discharge performance and high Comparative Tracking Index (CTI > 600V) to withstand higher internal electrical stresses in dry-air or vacuum-insulated switchgear.
High-voltage fast-charging stations (800V+ architecture) and megawatt-scale BESS containerization expose switchgear insulators to continuous high thermal loads, rapid heat dissipation needs, and chemical exposure. Specialized BMC insulators reinforced with flame-retardant aluminum trihydrate (ATH) offer UL 94 V-0 compliance, ensuring fire propagation barrier protection inside battery management cabinets.
Modern mission-critical data infrastructure demands uninterrupted power supply (UPS) switchboards with dense busbar configurations. Compact standoff insulators like the D-Series, SM-Series, and EL-Series deliver immense mechanical short-circuit strength (up to 200KN universal tension load tolerance) while reducing cabinet footprint and eliminating electrodynamic resonance under fault currents.

Selecting the optimal dielectric polymer matrix is paramount for switchgear design engineers. Flyaford custom-formulates raw materials in-house to tailor mechanical torque resistance, dielectric breakdown strength, thermal expansion match with brass/copper inserts, and long-term anti-aging capabilities.
| Material Matrix | Dielectric Strength (kV/mm) | CTI (Comparative Tracking Index) | Flame Retardancy (UL 94) | Operating Temp Range (°C) | Primary Industrial Applications |
|---|---|---|---|---|---|
| BMC (Unsaturated Polyester) | 18 - 24 kV/mm | CTI > 600 V (Class 1) | V-0 / 5VA Rated | -40°C to +140°C | Low/Medium Voltage Standoff Insulators, Busbar Supports (D, SM, EL Series) |
| EMC (Epoxy Molding Compound) | 22 - 30 kV/mm | CTI > 600 V | V-0 Self-extinguishing | -50°C to +180°C | Medium/High Voltage Switchgear Bushings, Arc Chutes, Partial Discharge Critical Cells |
| PF (Phenolic Formaldehyde) | 12 - 16 kV/mm | CTI 175 - 400 V | V-0 High Heat Stability | -30°C to +160°C | Low-Voltage Terminal Blocks, Structural Spacers, Retrofit Commercial Panels |
| Cycloaliphatic Epoxy (CEP) | 25 - 32 kV/mm | CTI > 600 V (Hydrophobic) | V-0 UV Resistant | -60°C to +200°C | Outdoor Reclosers, Substation Post Insulators, Harsh Environment Power Systems |
Internal threaded hardware inserts (Brass/Steel) are custom-engineered with multi-ribbed helical knurling. This design guarantees ultimate torsional pull-out strength (tested up to 500 N.m via microcomputer torque equipment), preventing insulator spinning during heavy busbar bolting.
By implementing high-vacuum degreasing during thermoset injection and compression molding, Flyaford eliminates internal micro-voids, maintaining Partial Discharge (PD) levels under < 5 pC at 120kV test voltages, drastically extending insulation life expectancy.
Complete in-house testing capability powering the Jinhua Feifav High-Performance Insulator Science and Technology R&D Center.
Quality at Flyaford is rooted in our dual certification framework: IATF 16949 (Automotive Industry Quality Management System) and ISO 9001. Every batch of raw resin, glass fiber, and metal hardware undergoes spectral component analysis before molding.
Finished insulator units are subjected to 100% full inspection mode for electrical breakdown resistance, mechanical flashover limits, and physical appearance dimensions. We hold certificates of compliance for EU Safety standards (CE), UL Flame Class, ROHS 2.0, and REACH environmental criteria.
