Flyaford
Engineered for high mechanical strength, flame retardancy (UL94 V-0), and superior dielectric protection.
Established in 2007, Zhejiang Flyaford Electron Co., Ltd. is positioned in the Jinyi New District of Jinhua City, Zhejiang Province. Operating across a modern 35,000 square meter standardized manufacturing complex, Flyaford has established itself as an authoritative global manufacturer and ODM/OEM supplier of low-voltage and medium-voltage switchgear insulators, busbar supports, and composite insulation accessories.
Driven by rigorous scientific R&D, Flyaford operates as a recognized "National High-Tech Enterprise" and a "Zhejiang Provincial Specialized, Refined, Distinctive, and Innovative SME." We serve as the designated insulator development partner for world-class research hubs, including Tsinghua University, translating advanced material science into industrial-grade electrical safety components.
Understanding the engineering metallurgy behind high-reliability BMC, DMC, EMC, and PF switchgear insulation components.
Bulk Molding Compound (BMC) and Dough Molding Compound (DMC) utilize unsaturated polyester resin reinforced with short glass fibers (15%-30%) and mineral fillers. Formulated for high mechanical shear resistance, exceptional arc resistance, and flame retardancy reaching UL94 V-0 standards without halogen toxicity.
For applications demanding higher thermal performance up to Class H (180°C) and tight dimensional tolerances, our specialized EMC formulations prevent micro-cracking under rapid thermal cycles, preserving dielectric strength across continuous 1000V+ operational environments.
Phenolic thermosetting insulations deliver exceptional structural rigidity, anti-tracking index (CTI ≥ 600V), and superior resistance to corrosive chemical environments, making them ideal for heavy-duty industrial switchboards, naval power distribution, and mining transformers.

High-durability step-shaped and barrel insulators designed for mid-to-heavy power transmission cubicles. Built with deep insert encapsulation for extreme mechanical stability.
CE-certified standard standoff insulators with brass inserts ranging from M6 to M12. The industry gold standard for general power distribution panels, control gear, and commercial switchboards.
Heavy-duty phase separator insulators providing optimal clearance between multi-phase busbars under high thermal expansion and high ambient temperatures.
T-type standoff insulators configured for modular busbar mounting system tracks, providing smooth installation alignment and fast cabinet assembly times.
Deploying reliable composite insulation across high-vibration, high-heat, and harsh environmental operating conditions worldwide.
Supporting main distribution busbars, circuit breaker compartments, and cable connection trunks in heavy-duty utility switchgear enclosures. Engineered to withstand high short-circuit electrodynamic forces without mechanical fracture.
Variable Frequency Drives create high-frequency harmonic vibrations and localized heat buildup. Flyaford insulators offer superior mechanical vibration damping and elevated thermal degradation resistance up to Class H temperatures.
Grid-scale lithium battery storage containers operate at up to 1500V DC continuous current. Our specialized BMC standoff insulators guarantee zero thermal runaway propagation, CTI 600 tracking immunity, and UL94 V-0 safety compliance.
Offshore and onshore wind turbines subject switchgear components to extreme salt fog humidity, high mechanical oscillation, and constant temperature swings. Flyaford insulators pass rigorous double 85 and salt spray testing.
High-power ultra-fast DC charging piles (350kW+) require compact, highly robust busbar supports certified to IATF 16949 automotive quality management standards to handle transient surges safely.
Central and string solar inverters demand outdoor-rated, UV-stable insulation posts that withstand direct solar exposure, humidity fluctuations, and continuous DC high-voltage isolation.
