Flyaford
Precision-engineered standoff busbar insulators certified to international electrical safety standards.
In contemporary power distribution networks, low-to-medium voltage switchgears act as the central nervous system for commercial facilities, industrial plants, renewable energy farms, and urban grid infrastructure. Among various standardized modular cabinet platforms, the MNS (Modular Low Voltage Switchgear System) framework stands out globally for its operational safety, flexible structure, and high power density capability. At the core of every MNS system is the mechanical and electrical insulation integrity of its internal busbar supports—specifically the MNS Series Insulator.
MNS Series Insulators serve two primary technical functions: providing robust mechanical support to withstand enormous electrodynamic forces during short-circuit faults, and ensuring complete electrical isolation between live phase conductors, neutral bars, and grounded structural frames. Engineered predominantly from advanced Bulk Molding Compounds (BMC) and Dough Molding Compounds (DMC), MNS insulators withstand severe thermal gradients, high dielectric voltage stresses, and aggressive environmental contaminants.
Exploring thermosetting composite formulations, insert anchor mechanics, and electrical isolation performance.
Formulated with unsaturated polyester resin reinforced with short glass fibers and inorganic fillers, offering unmatched mechanical rigidity, high arc resistance (>180s), and minimal thermal shrinkage during thermoset molding cycles.
Featuring ribbed outer profiles that extend surface tracking distance, preventing electrical arc-over under high moisture, dust accumulation, or chemical contamination in harsh industrial environments.
Cold-headed, diamond-knurled brass or zinc-plated steel fasteners integrally molded into the composite core to deliver extreme tensile pull-out resistance and withstand high tightening torque during busbar installation.
Situated in the Jinyi New District of Jinhua City, Zhejiang Province, Zhejiang Flyaford Electron Co., Ltd. was established in 2007. Over the past two decades, Flyaford has grown into a globally recognized leader specializing in the R&D, precision manufacturing, and sales of low-to-medium voltage insulators and electrical accessories.
Operating a state-of-the-art 35,000 square meter standardized manufacturing complex, Flyaford houses over 60 advanced thermosetting injection and compression molding presses, supported by an automated material blending and digital process control line. Producing over 200,000 precision component pieces daily, Flyaford maintains an industry-leading quality standard with a total defect rate below 100 PPM.
Recognized as a "National High-Tech Enterprise", "Zhejiang Provincial Specialized, Refined, Distinctive, and Innovative SME", and housing the "Jinhua High-Performance Insulator Science and Technology R&D Center", Flyaford collaborates continuously with top research institutions and Tsinghua University, serving as their official designated insulator supplier.
To guarantee absolute electrical safety and mechanical stability, Flyaford has invested millions into establishing a certified high-standard physical and electrical laboratory capable of exhaustive destructive and non-destructive evaluations.

MNS Series Insulators are custom-engineered to fit the standard mounting centers, structural profiles, and busbar spacing of MNS modular switchboard architectures. Their compact hex/cylindrical geometries maximize internal cubicle space while providing superior mechanical shear resistance under short-circuit electrodynamic forces up to 100kA.
Bulk Molding Compound (BMC) contains longer glass fibers (up to 12mm) than Dough Molding Compound (DMC), resulting in significantly higher flexural strength (up to 140 MPa) and impact resilience. Compared to traditional porcelain, BMC is non-brittle, shatter-proof under thermal shock, lighter in weight, and allows integrally molded high-precision metal inserts.
Flyaford insulators are certified under UL Recognized Component schemes, CE directives, ISO 9001 quality standards, and IATF 16949 automotive quality systems. Comprehensive test reports for UL94 V-0 flame retardancy, dielectric withstand voltage (up to 100kV), lightning impulse (up to 300kV), and ROHS 2.0/REACH SVHC chemical safety are readily available.
Yes. Flyaford maintains full in-house mold design and tooling capability. We offer custom thread sizes (Metric M6–M20 or Imperial UNC standards), variable insert depths, customized height steps, and specific color compounding (red, brown, grey, black) to match your brand specifications or phase identification schemes.
Creepage distance is calculated based on the maximum operational working voltage (Ue), pollution degree of the installation environment (typically Pollution Degree 3 for industrial switchgears according to IEC 60947-1), and the Comparative Tracking Index (CTI) group of the insulator material (BMC/DMC belongs to Material Group I with CTI ≥ 600V).
Standard catalog products are stocked for immediate dispatch within 3–7 business days. For custom ODM/OEM mold tooling and sample production, prototype samples are delivered within 15–20 days, followed by full volume mass production ramp-up supported by our 200,000 pcs/day daily capacity.
