Global Standard-Bearer in Low-to-Medium Voltage Composite Insulation Technology
Established in 2007 and headquartered in the Jinyi New District of Jinhua City, Zhejiang Province, ZHEJIANG FLYAFORD ELECTRON CO., LTD. has developed into a national high-tech enterprise occupying over 35,000 square meters of state-of-the-art standard manufacturing space. Specializing in the research, mechanical engineering, compound formulation, and automated molding of standoff insulators, busbar supports, and low-to-medium voltage electrical insulation components, Flyaford operates as a critical supply chain partner for tier-1 power equipment manufacturers worldwide.
Driven by rigorous scientific innovation, the enterprise maintains an official municipal-level R&D center: the Jinhua Feifaw High-Performance Insulator Science and Technology R&D Center. Through active academic and industrial research collaborations with top institutions—including Tsinghua University, where Flyaford serves as a designated engineering insulator supplier—the company continually pushes the boundaries of thermosetting composite performance, creepage path optimization, and mechanical fault tolerance.
Understanding the molecular properties, mechanical resilience, and dielectric strengths of P Series standoff insulators.
BMC consists of thermosetting unsaturated polyester resin blended with short glass fibers, mineral fillers (such as aluminum trihydrate for flame retardation), and catalysts. Compression molded under high pressure and temperature, P Series BMC insulators deliver high dimensional stability, flame retardancy (UL94-V0), and extreme arc tracking resistance (CTI ≥ 600V).
DMC, often used interchangeably with BMC in specific regional standards, features a dough-like fibrous matrix optimized for intricate mechanical geometries. P Series DMC insulators offer superior mechanical impact resistance and low water absorption (<0.2%), preventing dielectric breakdown under severe tropical moisture and humidity.
The structural integrity of a standoff insulator depends heavily on the internal brass or steel threaded inserts. Flyaford utilizes knurled brass inserts anchored deep within the composite core, providing exceptional pull-out torque resistance and zero loosening under vibrational stress in high-vibration power plants.

How clean energy transitions and grid digitalization are redefining requirement standards for low-to-medium voltage electrical equipment.
The global market for standoff insulators—specifically the P Series, SM Series, SB Series, and MNS Series—is undergoing unprecedented expansion. Driven by the global mandate for decarbonization, grid modernization, and industrial automation, electrical equipment manufacturers face escalating demands for component reliability, thermal resilience, and compact footprint design.
Aging electrical utility infrastructures in North America and Western Europe are undergoing rapid retrofit operations. Compact P Series busbar insulators enable high-density busbar arrangement inside modern distribution switchgears without sacrificing creepage clearance or dielectric isolation.
The exponential rise of utility-scale solar and wind storage requires massive DC/AC Power Conversion Systems (PCS). P Series insulators isolate high-amperage copper busbars operating under harsh ambient thermal loads, safeguarding against short-circuit flashovers.
High-power fast chargers (350kW+) and electric vehicle traction substations require UL-listed, flame-retardant composite standoff insulators designed to withstand continuous current pulses, harmonic vibrations, and thermal cycling.
As top-tier global P Series insulator suppliers, companies must not only deliver high volumetric manufacturing—such as Flyaford’s 200,000 pcs/day automated production capacity—but also maintain stringent quality control certified under IATF 16949 for automotive-grade reliability.
Pioneering future-proof insulation technologies to meet the challenges of 2025–2035 electrical environments.
Eliminating internal voids and micro-cavities within the composite molding resin to achieve complete partial discharge suppression up to 120kV testing thresholds.
Integrating IoT-enabled temperature and leakage current sensors directly into the P Series insulator body for real-time predictive grid maintenance.
Developing low-carbon, bio-derived unsaturated polyester resins that retain UL94-V0 flame ratings while reducing the product's overall carbon footprint.
Advanced geometric locking mechanics for metal inserts to withstand catastrophic electrodynamic short-circuit forces exceeding 50kA.

Expert insights on P Series standoff insulator selection, material specifications, and installation engineering.
P Series standoff insulators are manufactured primarily using BMC (Bulk Molding Compound) or DMC (Dough Molding Compound). These are thermosetting composite materials consisting of unsaturated polyester resin, short glass fiber reinforcement, inorganic mineral fillers, and fire retardants. This material matrix provides exceptional electrical insulation, mechanical strength, and UL94-V0 flame retardancy.
Flyaford's P Series BMC insulators feature high heat deflection temperatures (HDT > 200°C) and are rated for continuous operation across temperature ranges from -40°C up to +140°C. They do not soften or deform under elevated heat during electrical overload conditions.
Flyaford P Series insulators hold CE safety certification, UL product approval, ISO 9001 quality management certification, ISO 14001 environmental certification, and IATF 16949 automotive certification. Furthermore, all products comply strictly with RoHS 2.0 and REACH environmental directives.
The CTI rating measures the resistance of an insulating material to electrical tracking in the presence of surface contamination and moisture. P Series BMC insulators achieve a CTI 600 rating (the highest Class 0 rating under IEC 60112 standard), making them immune to carbon track formation and surface flashovers in polluted industrial environments.
