Explore our premium selection of BMC, EMC, and PF high-performance standoff insulators engineered for extreme anti-tracking and thermal stability.
Electrical tracking—the irreversible degradation of an insulating material's surface due to local electrical discharges and conductive path formation—remains one of the most critical causes of catastrophic failure in low and medium-voltage switchgear, energy storage systems (BESS), and industrial distribution panels. As global power networks shift toward higher power densities and compact form factors, the demand for **ODM Anti Tracking Insulators** with exceptional Comparative Tracking Index (CTI ≥ 600V) performance has surged.
Modern electrical engineering environments, including offshore wind turbines, solar inverter arrays, hyper-scale data centers, and EV fast-charging hubs, expose standoff insulators to severe atmospheric pollution, humidity fluctuations, and chemical contaminants. Traditional thermoset or lower-grade resin components succumb to surface carbonization over extended operating cycles. Advanced Bulk Molding Compound (BMC), Epoxy Molding Compound (EMC), and Phenolic Resin (PF) formulations engineered by Zhejiang Flyaford Electron Co., Ltd. address these micro-arcing vulnerabilities at the molecular level.
Key Technical Imperative: Implementing CTI Class 0 (600V+) thermosetting polymers prevents creepage discharge and catastrophic insulation breakdown, extending asset longevity beyond 25 years in polluted C4/C5 environments.
Zhejiang Flyaford Electron Co., Ltd. stands as a global leader in high-reliability low and medium voltage insulation solutions, operating under rigorous international automotive and industrial quality systems.
Situated in the Jinyi New District of Jinhua City, Zhejiang Province, Flyaford (established in 2007) operates over 60 high-precision molding machines and 20+ specialized testing apparatuses. We proudly collaborate with academic authority Tsinghua University as a designated insulator development partner, pioneering high-performance thermosetting composite applications.
Selecting the optimal polymer chemistry is paramount to guaranteeing surface anti-tracking, mechanical strength, and arc quenching capabilities.

Technical guidance and commercial purchasing insights from our engineering team.
Comparative Tracking Index (CTI) measures the voltage at which an electrical insulating material undergoes breakdown and forms a conductive tracking path when drops of contaminated water are repeatedly applied under voltage stress (per IEC 60112). A CTI rating ≥ 600V (Class 0) guarantees maximum resistance to surface arcing, essential for modern high-reliability equipment.
Bulk Molding Compound (BMC) provides superior mechanical shock resistance, lower mass, higher molding precision, and zero vulnerability to thermal cracking compared to traditional porcelain. Unlike standard epoxy resins, BMC incorporates specific flame-retardant and arc-extinguishing fillers that deliver high heat distortion stability at a more competitive cost structure.
We offer full-cycle ODM customization including custom height profiles, creepage distance extension, customized insert thread sizes (metric or imperial brass/steel inserts), color coding, thermoset formulation tweaking (BMC/EMC/PF), and custom branding/labeling with quick-turnaround tooling design.
Every batch of raw compound undergoes density, flammability, and CTI testing before molding. Finished products pass 100% full visual inspection and high-potential electrical testing, maintaining an industry-leading quality standard with a defect rate below 100 PPM.
Our in-house tool design center completes 3D mold modeling within 48 hours. Tooling fabrication and prototype sample submission typically take between 15 to 25 days depending on component complexity, followed by rapid mass production scaling.
Yes. All raw materials and finished composite insulators manufactured by Flyaford strictly comply with EU RoHS 2.0, REACH SVHC directives, UL94 V-0 flame ratings, and CE safety standards, making them fully eligible for global export.
