Flyaford
Explore our flagship high-performance standoff insulators engineered for power systems, battery energy storage systems (BESS), EV packs, and low-medium voltage distribution networks.
Modern power distribution, renewable energy integration, and heavy electrical automation demand unmatched mechanical rigidity, dielectric stability, and thermal resilience from busbar supports. SMC (Sheet Molding Compound) and DMC (Dough Molding Compound, also known as Bulk Molding Compound / BMC) have established themselves as the premier thermosetting composite materials for low-to-medium voltage electrical insulations.
Engineering Insight: Dynamic Electrodynamic Resistance
During a short-circuit fault, electrical busbars experience severe mechanical forces ($F \propto I_{peak}^2$). SMC/DMC busbar supports produced by Zhejiang Flyaford Electron Co., Ltd. are formulated to absorb extreme electrodynamic surge stresses up to 100 kA peak short-circuit ratings while maintaining strict dielectric integrity under high operating temperatures.
Exceeds IEC 60112 material group I standards, preventing electrical tracking under humid or contaminated conditions.
Self-extinguishing thermosetting matrix containing halogen-free Alumina Trihydrate (ATH) fillers.
Rigorous IATF 16949 automotive-grade quality controls across 60+ automated compression molding presses.
Scalable batch manufacturing across 35,000 m² state-of-the-art intelligent manufacturing facility.
Established in 2007, ZHEJIANG FLYAFORD ELECTRON CO., LTD. is positioned in the Jinyi New District of Jinhua City, Zhejiang Province. Operating from a 35,000 square meter standardized industrial complex, Flyaford has evolved into a global benchmark in low-to-medium voltage electrical standoff insulators, busbar supports, and custom thermosetting composite accessories.
Backed by over 120 dedicated specialists, a senior engineering taskforce, and 5 full-time R&D scientists, Flyaford operates a municipal-level High-Performance Insulator Science and Technology R&D Center. The company maintains long-standing academic-industrial research partnerships with prestigious institutions, including Tsinghua University, serving as their designated insulator development supplier.
Our core capabilities span end-to-end tooling design, precision metal insert machining, raw material formulation optimization (SMC, DMC/BMC, EMC, PF), and automated compression molding. Recognized as a National High-Tech Enterprise and a Zhejiang Provincial Specialized, Refined, Distinctive, and Innovative SME, Flyaford holds 26 patents—including 5 invention patents and 2 software copyrights.
To guarantee operational failure rates below 100 PPM, Flyaford maintains a state-of-the-art testing facility equipped with high-precision analytical and destructive test benches:
Microcomputer Torsion Tester (0-500 N.m) & Universal Testing Bench (0-200 kN) for cantilever and axial force validation.
Partial Discharge Shielded Room (0-120 kV), Lightning Impulse Generator (0-300 kV 1.2/50 μs), and Withstand Voltage Testers (0-100 kV).
Double 85 Chamber, Thermal Shock Chamber (-40°C to +140°C), High Temp Oven (0-300°C), and Cryogenic Testing (-86°C to 0°C).
Choosing the correct polymer resin and reinforcement geometry dictates the operational safety and lifespan of busbar support systems in hostile environmental conditions.
| Property Parameter | SMC (Sheet Molding Compound) | DMC / BMC (Bulk Molding Compound) | Engineering Benefit |
|---|---|---|---|
| Glass Fiber Reinforcement | Long Glass Fibers (25mm - 50mm), 25% - 30% Content | Short Chopped Fibers (6mm - 12mm), 15% - 20% Content | SMC delivers superior flexural and tensile strength for long-span busbars. |
| Mechanical Flexural Strength | 160 MPa - 200 MPa | 100 MPa - 140 MPa | Resists severe lateral deflection during short-circuit electromagnetic spikes. |
| Dielectric Strength (KV/mm) | > 18 kV/mm | > 15 kV/mm | Prevents dielectric breakdown between phases and ground enclosure. |
| Comparative Tracking Index (CTI) | CTI 600 (PLC Grade 0) | CTI 600 (PLC Grade 0) | Maximum resistance to surface carbon tracking in high-humidity/polluted environments. |
| Flame Retardancy & Toxicity | UL 94 V-0, Low-Smoke Halogen-Free | UL 94 V-0, Low-Smoke Halogen-Free | Self-extinguishing properties safeguard against fire propagation in enclosed switchgear. |
| Dimensional Stability & Creep | Near-Zero Shrinkage (<0.05%) | Low Shrinkage (<0.1%) | Maintains tight thread engagement torque under continuous thermal cycling (-40°C to +130°C). |
Flyaford’s in-house chemical blending process incorporates unsaturated polyester resins cross-linked with styrene monomers, reactive fillers, and anti-shrink additives. The inclusion of fine-grade Aluminum Trihydrate (ATH) provides dual functionality: absorbing endothermic energy to suppress fire while mitigating smoke density during high-temperature thermal events.
Mechanical failures in busbar supports often originate at the metal-insert composite interface. Flyaford utilizes knurled, high-tensile brass (CZ121/C36000) or zinc-plated carbon steel inserts with blind-hole threading. Integrated via transfer or direct compression insert molding, our inserts withstand torque forces up to 500 N.m without pull-out or radial cracking.
