Understanding the dielectric, mechanical, and thermal parameters that govern next-generation ODM insulator substance manufacturing.
In modern high-power electrical distribution, renewable energy generation (photovoltaic, wind power), battery energy storage systems (BESS), and electric vehicle (EV) charging infrastructure, low and medium-voltage standoff insulators perform a critical dual role: structural load-bearing and absolute electrical isolation. Selecting the appropriate ODM insulator substances is paramount to preventing dielectric breakdown, tracking index degradation, thermal runaway, and mechanical catastrophic failure under high-current electrodynamic fault stresses.
Choosing the ideal resin matrix directly affects tensile strength, short-circuit current withstand capabilities, moisture absorption, and thermal aging traits. Below is a comparative performance evaluation based on rigorous laboratory benchmarks:
| Insulator Substance / Material | Dielectric Strength (kV/mm) | Comparative Tracking Index (CTI) | Flexural / Tensile Strength | Flammability Rating | Primary Industrial Application |
|---|---|---|---|---|---|
| BMC (Bulk Molding Compound) | 18 - 24 kV/mm | CTI 600V (PLC 0) | High (140-180 MPa) | UL 94 V-0 (Halogen-Free) | Busbar supports, Switchgear, SM/SEP series, BESS enclosures |
| EMC (Epoxy Molding Compound) | 22 - 30 kV/mm | CTI 600V | Very High (>200 MPa) | UL 94 V-0 / V-1 | High-voltage indoor breakers, critical aerospace power electronics |
| PF (Phenolic Resin / Bakelite) | 12 - 16 kV/mm | CTI 175V - 300V | Moderate (90-120 MPa) | UL 94 V-0 / 5VA | Legacy low-voltage isolation, cost-sensitive terminal blocks |
| High-Grade Porcelain (C-120) | 15 - 20 kV/mm | CTI > 600V | Brittle (Tensile < 50 MPa) | Non-Combustible | Outdoor transmission lines, extreme atmospheric substations |
A National High-Tech Enterprise and Zhejiang Provincial Specialized, Refined, Distinctive, and Innovative SME specializing in advanced low-to-medium voltage electrical insulation solutions.
ZHEJIANG FLYAFORD ELECTRON CO., LTD. is situated in the Jinyi New District of Jinhua City, Zhejiang Province. Established in 2007, the company specializes in the research and development, production, and sales of insulators, insulation accessories, and custom polymer components. We are deeply committed to becoming a global leader in high-reliability electrical insulation engineering.
As a specialized manufacturer focused on low-voltage to medium-voltage insulation products, our testing equipment is comprehensive, and we possess industry-leading R&D capabilities. We offer a complete range of high-quality products at competitive prices, serving global clients across new energy vehicles (NEVs), 5G telecommunication switchgear, smart grid energy storage, intelligent robotic control systems, and high-speed rail power infrastructure.
We have obtained IATF 16949 automotive quality management system certification, UL safety certification, ISO 9001 quality management, ISO 14001 environmental management, and CE EU safety compliance. All raw materials undergo strict testing for ROHS 2.0 and REACH standard adherence.
Combining complete upstream raw material supply chains, rapid mold prototyping, and automated compression molding scale.
China's industrial cluster in Zhejiang enables direct sourcing of high-purity unsaturated polyester resins, glass fiber strands, ATH fillers, and brass/steel threaded inserts. This eliminates long supply lead times and guarantees raw material consistency across high-volume production batches.
Equipped with over 60 high-tonnage hydraulic molding presses, our automated smart factory monitors curing temperature curves, pressure cycles, and mold parting lines in real-time. This guarantees strict dimensional tolerance control (within ±0.05mm) and keeps product defect rates under 100 PPM.
As the designated insulator supplier for Tsinghua University and home to the Jinhua High-Performance Insulator R&D Center, Flyaford bridges theoretical polymer science with scalable factory manufacturing. Our 6-person full-time R&D team holds 26 patents driving innovation in zero-halogen flame retardancy.
To guarantee ultimate product reliability under harsh industrial operations, Flyaford maintains a state-of-the-art laboratory housing over 20 advanced analytical instruments.
Custom ODM insulator compounds engineered to excel in high-vibration, high-humidity, and heavy chemical environments.
Serving MNS, GCS, and KYN28 switchgear installations. Our BMC standoff insulators provide rigid mounting for solid copper busbars during high short-circuit electromagnetic stress spikes.
High-frequency switching in modern VFD control cabinets generates harmonic voltage spikes. Our low loss-factor polymer formulas resist thermal degradation caused by harmonic heating.
Containerized utility battery racks require compact, UL94 V-0 rated insulators with excellent creepage distance to safeguard high-density DC busbars against fire hazards.
Tower nacelles suffer continuous dynamic vibration and salt mist exposure. Reinforced glass-fiber polymer formulations ensure long-term mechanical shear stability without cracking.
Compliant with IATF 16949 automotive standards, our lightweight composite insulator components isolate high-voltage traction battery packs and fast-charging distribution boxes.
Direct current solar farms demand components capable of withstanding UV radiation, high ambient temperatures, and daily thermal expansion cycling without structural fatigue.

Bulk Molding Compound (BMC) and Dough Molding Compound (DMC) are thermosetting polyester formulations reinforced with glass fibers (typically 10%-20% fiber length). They offer an optimal balance of cost, mechanical flexural strength, and high Comparative Tracking Index (CTI 600V). Epoxy Molding Compound (EMC) provides higher mechanical modulus and superior chemical resistance for ultra-demanding environments. Phenolic Resins (PF/Bakelite) offer high temperature resistance but lower comparative tracking index performance compared to modern BMC compounds.
Insert stripping or pull-out failure is a major risk in busbar mounting. Flyaford uses high-precision knurled brass (H59/H62) or zinc-plated steel inserts. During compression molding, our automated presses ensure full thermosetting compound penetration around the insert knurling. Every batch undergoes microcomputer torque testing (0-500 N.m) and axial tensile pull-out verification (up to 200 KN) to meet stringent mechanical load standards.
Battery Energy Storage Systems (BESS) operate with high DC currents. In the rare event of a battery thermal runaway or electrical short circuit, insulator materials must self-extinguish rapidly without flaming drips. UL94 V-0 certification guarantees that the insulating compound stops burning within 10 seconds on a vertical specimen, halting fire propagation within the electrical enclosure.
Yes. Flyaford offers complete one-stop ODM/OEM engineering. Our in-house mold facility designs and cuts custom compression tooling based on client STEP/DWG files. We assist in selecting the optimal resin matrix, conducting DFM simulations, prototyping initial samples, and delivering full-scale certified production runs.
We operate under strict IATF 16949 (Automotive Quality Management System) and ISO 9001 quality frameworks, as well as ISO 14001 environmental management systems. Products carry CE safety certifications, UL recognition, and comply fully with ROHS 2.0 and REACH environmental standards.
