Flyaford
Explore our CE-certified low and medium-voltage BMC, DMC, EMC, and PF thermosetting standoff insulators engineered for severe mechanical and electrical stress environments.
A comprehensive analysis of structural dielectric dynamics, thermal stress isolation, and compliance frameworks governing modern low-to-medium voltage switchgear infrastructure.
Modern electrical power distribution architectures demand unprecedented levels of operational safety, mechanical durability, and dielectric stability. Within low-voltage (LV) and medium-voltage (MV) switchboards, panelboards, and motor control centers (MCC), switchboard component insulators serve as the structural backbone that supports copper and aluminum busbar configurations while maintaining galvanic isolation under severe electrodynamic stresses.
Obtaining authentic CE Certification is not merely a regulatory prerequisite for European Union market access under the Low Voltage Directive (LVD) 2014/35/EU; it is a rigorous validation of insulation safety, dielectric clearance, creepage distance, and flammability resilience. Electrical engineers, original equipment manufacturers (OEMs), and panel builders globally rely on certified composite insulators formulated from Bulk Molding Compound (BMC), Dough Molding Compound (DMC), Epoxy Molding Compound (EMC), and Phenolic Resins (PF) to prevent catastrophic flashovers, thermal runaway, and mechanical deformation caused by peak short-circuit fault currents.
Established in 2007 in Jinyi New District, Jinhua City, Zhejiang Province — Pioneering low-to-medium voltage electrical insulation composite technology globally.
Zhejiang Flyaford Electron Co., Ltd. spans over 35,000 square meters of modern standardized industrial real estate, housing more than 60 high-precision thermosetting compression molding machines and 20+ specialized testing apparatuses. Employing over 120 skilled technicians, the company operates under stringent IATF 16949 (Automotive Quality Management) and ISO 9001 quality systems.
Flyaford is officially recognized as a "National High-Tech Enterprise", "Zhejiang Provincial Specialized, Refined, Distinctive, and Innovative SME", and houses the recognized "Jinhua Flyaford High-Performance Insulator Science and Technology R&D Center".
Flyaford maintains an elite internal R&D squad featuring a senior principal engineer and five full-time research scientists. Demonstrating unmatched technical expertise, Flyaford has established deep collaborative industry-university-research partnerships with regional and national academic centers in Jinhua, Hangzhou, and Tsinghua University.
Notably, Flyaford serves as the designated insulator supplier for Tsinghua University engineering projects, co-developing high-dielectric composite formulations and micro-arc resistance mechanisms.

















Fully compliant with IEC 61439-1 & UL 891 standards, covering all low and medium voltage busbar support configurations.
Understanding Bulk Molding Compounds (BMC), Dough Molding Compounds (DMC), Epoxy Molding Compounds (EMC), and Phenolic (PF) Formulations.
Bulk Molding Compounds (BMC) and Dough Molding Compounds (DMC) utilize unsaturated polyester resin reinforced with 15%–30% chopped glass fibers (E-glass). Under heat (140°C–160°C) and compression molding pressure, cross-linking yields zero melting behavior, exceptional dimensional stability, and UL 94 V-0 self-extinguishing flame rating.
For high-frequency inverter cabinets and extreme temperature environments, Epoxy Molding Compounds (EMC) and Phenolic (PF) formulations provide elevated Comparative Tracking Index (CTI > 600V), preventing carbon tracking micro-paths under continuous electrical field stress and condensation exposure.
Inserts made of brass (H59/H62) or zinc-plated steel are knurled and overmolded inside the polymer matrix. Thread integrity is rigorously checked via automated microcomputer torque testing (0-500 N.m) to guarantee zero striping during busbar tightening in switchboard assembly.
