Flyaford
Engineered for extreme thermal conditions, superior flame retardancy (UL94 V-0), and uncompromising electrical isolation.
In modern electrical grid modernization, battery energy storage systems (BESS), electric vehicles (EV), and high-frequency industrial power distribution, insulating components face unprecedented thermal and dielectric stress. The global industrial shift towards higher power densities demands standoff insulators capable of sustained operation at temperatures exceeding 150°C to 300°C without mechanical degradation, partial discharge, or electrical tracking.
As a leading China-based manufacturer, Zhejiang Flyaford Electron Co., Ltd. sets the benchmark for high-temperature resistance insulators. By leveraging advanced Bulk Molding Compounds (BMC), Dough Molding Compounds (DMC), and specialized Phenolic Resins (PF), Flyaford delivers robust standoff solutions certified under strict CE standards, IATF 16949 automotive frameworks, and UL 94 V-0 flame resistance protocols.
CE certification is not merely a mark of compliance—it validates compliance with EN 60664-1 (Insulation coordination for equipment within low-voltage systems) and EN 60243-1 (Electric strength of insulating materials). Flyaford’s CE-certified insulator lines guarantee international buyers zero field failure rates, minimal arc tracking risk, and seamless compliance across European, American, and Asia-Pacific power infrastructure projects.
Located in Jinyi New District, Jinhua City, Zhejiang Province. Established in 2007, pioneering composite insulator R&D and automated smart manufacturing.
Flyaford is designated as the official insulator research and supply partner for Tsinghua University. Recognized as a "National High-Tech Enterprise" and "Zhejiang Provincial Specialized, Refined, Distinctive, and Innovative SME", our center hosts top-tier electrical engineers and materials scientists.
We strictly adhere to IATF 16949 automotive management systems, alongside ISO 9001 and ISO 14001. All raw materials and finished composite insulators carry full compliance reports for RoHS 2.0, REACH, UL certification, and CE safety standards.
With over 60 high-precision molding machines and 20+ specialized testing devices, our digitally connected production environment tracks raw material heating, molding pressures, insert co-molding, and real-time defect monitoring automatically.





Evaluating Bulk Molding Compound (BMC), Sheet Molding Compound (SMC), and Phenolic Resin performance under elevated thermal and electrical stress.
High-temperature resistance standoff insulators rely on precise formulation of thermosetting resins reinforced with chopped glass fibers, mineral fillers, and specialized flame-retardant additives. Thermosetting polymers create cross-linked chemical bonds during high-pressure hot compression molding, rendering them non-melting and structurally stable up to critical degradation limits.

A critical failure point in high-temperature standoff insulators is insert detachment or cracking caused by mismatched thermal expansion coefficients between metal inserts (copper/brass/steel) and the polymer body. Flyaford utilizes patented knurling designs and stress-absorbing interlayers to guarantee zero torque shear under extreme thermal cycling (-40°C to +140°C).
By engineering specialized ribbing geometries (such as found in our D Series, SM Series, and SEP Series insulators), Flyaford optimizes surface creepage paths. This prevents tracking arcs and surface flashover, even in contaminated environments such as coastal wind farms or dusty industrial switchgear enclosures.

Expert answers regarding CE standards, material properties, and procurement guidelines.
Flyaford BMC (Bulk Molding Compound) and specialized composite insulators feature a Heat Deflection Temperature (HDT) exceeding 240°C under 1.8 MPa pressure. Under transient thermal shock conditions, our insulators withstand up to 300°C in high-temperature test chambers without melting, structural softening, or dielectric tracking.
CTI measures a material's resistance to electrical surface breakdown (tracking) under polluted conditions with moisture or dust. A CTI rating of 600V (PLC Class 0) represents the highest achievable insulation standard, ensuring maximum reliability and preventing arc paths in demanding switchgear, wind energy, and battery storage setups.
We utilize high-precision threaded brass and steel inserts engineered with aggressive diamond knurling. During thermosetting compression molding, the polymer cross-links tightly around the insert. Every batch is tested on our microcomputer torsion testing machine (0-500 N.m) to verify mechanical holding strength under severe installation torques.
Flyaford products are certified under CE (EN 60664-1 / EN 60243-1), IATF 16949 (Automotive Management System), ISO 9001, and ISO 14001. Comprehensive inspection reports for UL 94 V-0 flame rating, RoHS 2.0, and REACH are available for every delivery batch upon request.
