Discover our featured high-stability thermosetting standoff insulators, precision-engineered for compact power distribution architectures and demanding electrical insulation standards.
In modern power distribution systems, high-density low-voltage switchgears, and electric vehicle (EV) battery management architectures, spatial optimization without compromising dielectric integrity represents a paramount engineering objective. The demand for compact, highly durable 18mm width insulators has escalated exponentially alongside the global shift toward electrification, renewable energy storage (BESS), and intelligent power control cabinets.
As a premier global wholesale exporter and high-tech manufacturer, ZHEJIANG FLYAFORD ELECTRON CO., LTD. delivers structural and thermal insulation innovations designed to withstand severe electrical stress, mechanical vibration, and extreme atmospheric exposure. By deploying advanced Bulk Molding Compounds (BMC) and Sheet Molding Compounds (SMC) engineered with unsaturated polyester resins reinforced with fiberglass, our 18mm series delivers unprecedented dielectric strength (>25 kV/mm) and mechanical shear resistance in minimal dimensional footprints.

Situated in the Jinyi New District of Jinhua City, Zhejiang Province, ZHEJIANG FLYAFORD ELECTRON CO., LTD. (established in 2007) is a recognized global pioneer in low-to-medium voltage electrical insulation technology. Operating out of a state-of-the-art 35,000 square meter standardized manufacturing facility, we specialize in the continuous R&D, precision molding, and international export of thermosetting insulators and specialized insulation accessories.
Equipped with over 60 advanced compression molding machines, 20+ micro-precision test setups, and a highly skilled workforce of 120+ specialized technicians, our daily output exceeds 200,000 units. Through intelligent process automation and real-time digital monitoring, we maintain a product defect rate consistently below 100 PPM (Parts Per Million).
Recognized as a "National High-Tech Enterprise", "Zhejiang Provincial Specialized, Refined, Distinctive, and Innovative SME", and the home of the "Jinhua Feifav High-Performance Insulator Science and Technology R&D Center", Flyaford holds complete quality certifications including IATF 16949 (Automotive Management System), ISO 9001, ISO 14001, UL Certification, and European CE Safety Certification. All composite raw materials strictly comply with RoHS 2.0 and REACH standards.
Global OEM switchgear manufacturers, power grid contractors, and BESS integrators face severe pressure regarding supply chain resilience, cost management, and rapid customized turnaround. Sourcing wholesale 18mm width insulators directly from China's premier manufacturing ecosystem—specifically the Zhejiang industrial cluster—presents major technical and economic advantages:
By deploying over 60 high-tonnage thermosetting compression molding machines, automated material dosing, and robotic demolding setups, we eliminate human variability in bulk density and thermal curing, achieving unmatched structural homogeneity.
The mechanical reliability of an 18mm insulator depends heavily on the knurling design of its internal threaded brass or steel inserts. Flyaford designs and produces high-torque anti-rotation hardware inserts in-house, preventing insert displacement under thermal stress.
We partner directly with leading international resin suppliers, custom blending Unsaturated Polyester Resin, structural fiberglass, and alumina trihydrate (ATH) flame retardants. Full ROHS 2.0 and REACH chemical compliance is verified on every raw batch.
To ensure zero defect rates and high operational security in real-world power networks, Flyaford maintains an elite R&D center established in technical collaboration with renowned institutions, including Tsinghua University. We are proud to be the designated insulator supplier for Tsinghua University’s electrical research projects.
Our high-standard testing laboratory carries out 100% rigorous validation across all mechanical, electrical, thermal, and chemical dimensions using advanced equipment:
The 18mm width insulator is engineered for application environments where space-saving geometry must pair with uncompromising creepage distances and mechanical load capabilities. Key application sectors include:
Used as busbar supports and phase separators in air-insulated switchgear (AIS) assemblies. Resists high short-circuit electrodynamic forces and thermal surges.
Provides isolation against high-frequency harmonics, voltage spikes (dV/dt), and electromagnetic radiation generated by modern industrial variable frequency drives (VFDs).
Critical isolation within high-voltage DC battery racks, containerized energy storage units, and megawatt-scale power conversion systems (PCS).
Handles continuous structural vibration, wide environmental temperature swings, and severe humidity within offshore and onshore clean energy generators.
Complies with IATF 16949 standards for isolation of DC fast-charging stations, heavy-duty electric bus chassis distribution boxes, and automotive battery modules.
Ensures fire safety, arc track resistance, and zero halogen off-gassing in dense urban subway traction substations and commercial building distribution networks.
In addition to our flagship 18mm width series, Flyaford manufactures a comprehensive spectrum of standard and customized standoff busbar insulators:
