Flyaford
Explore our OEM/ODM-certified Bulk Molding Compound (BMC/EMC) standoff busbar insulators optimized for ultimate mechanical creepage, thermal stability, and electrical isolation performance.
The global transition toward high-density renewable energy, massive electrification, and microgrid decentralization has fundamentally reshaped the technical metrics demanded of standoff insulators. Traditional ceramic and early-generation phenolic insulators are increasingly being superseded by advanced Bulk Molding Compound (BMC) and Epoxy Molding Compound (EMC) continuous-strand glass-reinforced polymer matrices.
Specifically, the SB Series Insulator family (spanning SB 14-20 to SB 25-60) represents the gold standard in mechanical shock absorption, thermal gradient resistance, and flame-retardant structural isolation. As low and medium-voltage switchgears grow more compact to accommodate space-constrained urban substations and containerized Battery Energy Storage Systems (BESS), the requirement for ultra-high Comparative Tracking Index (CTI ≥ 600V) and zero-halogen flame resistance (UL 94 V-0) has become paramount.
Engineered to operate continuously across extreme thermal windows (-40°C to +140°C) without thermal degradation or dielectric breakdown under peak load surges.
Hexagonal and ribbed exterior contours maximize external creepage distance, minimizing risk of flashover in high-humidity or saline industrial environments.
Deeply knurled brass/steel threaded inserts molded under high pressure guarantee torsional stability during high-vibration busbar torque assembly.
Situated in the Jinyi New District of Jinhua City, Zhejiang Province, ZHEJIANG FLYAFORD ELECTRON CO., LTD. was established in 2007. We are a premier high-tech enterprise specializing in R&D, continuous-compression molding, and sales of low-to-medium voltage insulators and electrical accessories, committed to becoming a global leader in power isolation systems.
FLYAFORD has been officially awarded prestigious designations including "National High-Tech Enterprise", "Zhejiang Provincial Specialized, Refined, Distinctive, and Innovative SME", "Zhejiang Provincial Innovative SME", and houses the designated "Jinhua Feifav High-Performance Insulator Science and Technology R&D Center". Furthermore, Flyaford is the verified designated insulator R&D partner and supplier for Tsinghua University.








Our SB Series Standoff Insulators utilize proprietary Bulk Molding Compounds (BMC/EMC) consisting of unsaturated polyester resin reinforced with short glass fibers (20-30%) and inorganic mineral fillers. This matrix guarantees exceptional mechanical strength and arc endurance under violent short-circuit electrodynamic forces.
