Advanced Thermosetting BMC/DMC/EMC Standoff Insulators, Busbar Supports & Engineering Dielectric Components for High-Reliability Electrical Infrastructure
Precision-engineered Bulk Molding Compound (BMC) and Sheet Molding Compound (SMC) insulators designed for low to medium-voltage power distribution applications.
ZHEJIANG FLYAFORD ELECTRON CO., LTD., situated in the Jinyi New District of Jinhua City, Zhejiang Province, has established itself as an authoritative global pioneer in electrical isolation technologies since its founding in 2007. Specializing in the research, development, precision formulation, and automated molding of electrical insulation mediums, standoff insulators, and busbar supports, Flyaford operates a state-of-the-art 35,000-square-meter standard manufacturing plant.
Modern electrical distribution, energy storage systems (ESS), variable frequency drives (VFD), and electric vehicle (EV) charging stations demand extreme thermal stability, mechanical torque resistance, and flawless dielectric insulation properties. As an OEM/ODM insulation medium partner, Flyaford bridges the gap between raw thermosetting polymer science and heavy-duty electrical engineering.
Information Gain Insight: Unlike standard thermoplastic insulators (such as Nylon or ABS), engineered thermosetting composites—specifically Bulk Molding Compounds (BMC), Dough Molding Compounds (DMC), Epoxy Molding Compounds (EMC), and Phenolic Plastics (PF)—do not undergo thermal softening or melting under extreme overload temperatures, providing structural stability up to 300°C and maintaining dielectric integrity during severe short-circuit electromagnetic stresses.
Selecting the correct insulation medium is critical for optimizing system lifetime, tracking resistance (CTI), and mechanical load capacity in power distribution switchgears and transformer enclosures. Below is an engineering overview of the primary dielectric compound categories utilized in Flyaford OEM manufacturing:
Formulated from unsaturated polyester resin, short glass fibers, mineral fillers, and catalysts. BMC offers exceptional arc resistance, CTI ≥ 600V, and UL94 V-0 flame retardancy. Ideal for standard standoff insulators (SM, SB, P, D, EL series).
Engineered for high-voltage dielectric insulation requiring superior chemical immunity and minimal moisture absorption. Delivers elevated mechanical flexural strength (≥ 120 MPa) for heavy busbar containment setups in extreme marine or industrial environments.
Optimized for thermal insulation and high continuous operating temperatures (up to 180°C continuous). Excellent dimensional stability under compressive torque load, avoiding creep deformation around brass/steel threaded inserts.
Flyaford products are rigorously benchmarked according to international electro-technical standards. Below are the standard design parameters for our low and medium voltage standoff busbar insulators:
| Performance Parameter | Test Standard / Method | Technical Benchmark Value | Engineering Benefit |
|---|---|---|---|
| Rated Operating Voltage | IEC 60664-1 / UL 891 | 600V - 12kV (Low to Medium Voltage) | Prevents flashover & dielectric breakdown |
| Comparative Tracking Index (CTI) | IEC 60112 / ASTM D2303 | CTI ≥ 600V (Material Group I) | Prevents conductive path formation in high-humidity/dust settings |
| Flame Retardancy Rating | UL 94 Vertical Burning | UL 94 V-0 (Self-extinguishing within 10s) | Mitigates fire propagation risk in electrical cabinets |
| Torsion Load Resistance | Microcomputer Torsion Tester | 0 - 500 N.m custom range | Prevents thread stripping or internal insert loosening during installation |
| Tensile & Flexural Strength | Universal Test (0-200KN) | Tensile ≥ 40 MPa / Flexural ≥ 90 MPa | Withstands severe short-circuit electrodynamic forces |
| Thermal Shock Endurance | Test Chamber (-40°C to +140°C) | 100+ continuous thermal cycles | Zero micro-cracking under rapid temperature fluctuations |
| Insulation Resistance | High-Resistivity Meter (0-1TΩ) | ≥ 1,000 MΩ at 1,000V DC | Ensures near-zero leakage current across system lifetime |

BMC (Bulk Molding Compound) thermosetting composites combine high mechanical flexural strength with exceptional thermal shock tolerance and shatter-proof resilience. Unlike ceramics, BMC insulators will not crack during high-torque bolt tightening. Unlike thermoplastics, BMC does not soften under continuous high operating temperatures and achieves UL94 V-0 flame rating with CTI ≥ 600V.
