Explore our top-tier precision-molded busbar support insulators certified under international safety standards.
Understanding material physics, short-circuit electrodynamic force resistance, and thermosetting composite superiority over legacy porcelain and standard thermoplastic insulators.
Sheet Molding Compound (SMC) incorporates continuous chopped glass fiber reinforcements (25-30% volume ratio) within an unsaturated polyester/vinyl ester resin matrix. This delivers exceptional flexural strength (>160 MPa) and tensile strength (>80 MPa), enabling busbar supports to withstand peak short-circuit electrodynamic forces (Ipk > 100kA) without structural micro-cracking.
Compounded with high loadings of alumina trihydrate (ATH), our SMC formulations achieve self-extinguishing flame retardancy ratings of UL94 V-0 at 1.5mm thickness, paired with low smoke generation and halogen-free toxicity compliance, guaranteeing fire safety in high-density power switchgear and sub-stations.
Engineered for high electrical integrity, SMC insulators exhibit a dielectric strength exceeding 12-15 kV/mm, comparative tracking index (CTI) ratings of CTI 600V (PLC Class 0), and exceptional resistance to surface arcing under high humidity and heavily polluted operating micro-environments.

From utility-scale energy storage systems to high-speed rail electrification, Flyaford SMC insulators deliver mission-critical galvanic isolation.
With the rise of high-voltage DC (1500V DC) megawatt battery energy storage cabinets and electric vehicle fast-charging infrastructure, our SMC standoff insulators (T-Type, D-Type, SM Series) offer minimal partial discharge (< 5 pC) and non-hygroscopic performance, ensuring thermal runaway isolation and voltage containment.
Designed for installation in MNS, GCS, GCK, and KYN28 low and medium-voltage switchboards, our busbar supports provide robust mechanical positioning for solid copper and aluminum busbars, maintaining rigid phase-to-phase and phase-to-ground clearances during heavy harmonic load fluctuations.
Offshore wind turbines and utility-scale PV central inverters face extreme environmental stressors: salt spray, severe vibration, ambient temperature swings (-40°C to +140°C). Our UV-stabilized and salt-fog resistant composite insulators ensure 25+ years of operational maintenance-free service life.
Industrial motor drives and high-power VFD control panels demand low dielectric loss materials to manage high-frequency switching spikes (PWM voltage stress). Flyaford SMC/BMC insulators maintain high insulation resistance (>1 TΩ) preventing insulation breakdown under rapid dV/dt transients.
Modern cloud computing data centers require dynamic busway power distribution. Our compact, high-precision molded insulators (SEP, SB Series) support ultra-dense copper busduct assemblies, delivering space-saving footprints with maximum thermal heat dissipation properties.
Subway and high-speed rail electrification switchgear is subjected to continuous mechanical shocks and vibrations. Our high-torque brass/steel threaded insert designs prevent thread stripping and rotational slippage under structural dynamic loading.
Situated in Jinyi New District, Jinhua City, Zhejiang Province, ZHEJIANG FLYAFORD ELECTRON CO., LTD. operates a 35,000 m² state-of-the-art intelligent manufacturing hub.
Our smart factory leverages automated raw material compounding, hydraulic multi-cavity press molding, and real-time digital process monitoring. Every batch of SMC/BMC resin mix undergoes viscosity testing, resin flow verification, and gel-time monitoring. Fully integrated ERP/MES systems ensure raw material lot traceability from incoming resin down to individual packaged standoff insulators.
Honored as a "National High-Tech Enterprise" and "Zhejiang Provincial Specialized, Refined, Distinctive, and Innovative SME", Flyaford maintains a municipal-level High-Performance Insulator Science and Technology R&D Center. We maintain long-term industry-university-research partnerships with regional universities and are an officially designated insulator supplier for Tsinghua University research projects.
Driving composite material science forward to meet the evolving demands of ultra-high voltage (UHV) DC power grids and sustainable green energy ecosystems.
Integrating surface-modified nano-silica and graphene oxide into thermosetting BMC/SMC matrix formulations to boost thermal conductivity (> 1.2 W/m·K) while simultaneously suppressing partial discharge formation under ultra-fast dV/dt pulse loads generated by modern SiC/GaN power electronics.
In response to global carbon neutrality imperatives (Scope 3 emissions reduction), Flyaford is pioneering bio-derived unsaturated polyester resins synthesized from renewable bio-polyols, cutting life-cycle embodied carbon by up to 35% without compromising mechanical or electrical specs.
