Flyaford
Certified Low-Medium Voltage Insulators Engineered for Modern Power Systems and Switchboards
In-Depth Technical Analysis of Market Requirements in Bucharest, Cluj-Napoca, Dobrogea & Beyond
Romania is undergoing a profound energy sector transformation aligned with its National Integrated Energy and Climate Plan (PNIESC). With significant EU REPowerEU capital influxes, state grid operators like Transelectrica alongside regional distribution system operators (DSOs) such as Delgaz Grid, Distribuție Energie Electrică România (DEER), and Rețele Electrice are aggressively modernizing aging medium and low-voltage electrical substations.
Within this macro environment, **SB Series Bulk Molding Compound (BMC) standoff insulators** play a critical structural role. Designed to withstand dynamic short-circuit electromagnetic stresses and extreme ambient temperature fluctuations, SB series insulators provide vital mechanical isolation for primary copper and aluminum busbars inside switchgear assemblies across Romanian industrial parks.
Southern Romania (Wallachia and Moldavia) is experiencing a solar PV mega-boom, while the Dobrogea coastal region continues to expand onshore wind capacities alongside emerging Black Sea offshore developments. Utility-scale solar farms require robust inverter transformers, combiner boxes, and Central Inverter Stations operating at high DC/AC voltages under demanding outdoor environmental conditions.
Flyaford’s **SB 14-20 and SB 25-60 Series BMC Insulators** are specifically engineered with UL 94-V0 flame retardancy, high tracking resistance (CTI ≥ 600V), and excellent moisture protection, eliminating breakdown risks in high-humidity solar container stations and offshore coastal substations in Constanța.
Thermosetting Composite Polymer Science & Precision Machined Hardware Inserts
SB Series busbar standoff insulators manufactured by Zhejiang Flyaford Electron Co., Ltd. utilize specialized thermosetting Bulk Molding Compound (BMC/DMC)—a composite formulation of unsaturated polyester resin, high-purity structural glass fiber reinforcement, inorganic mineral fillers, and anti-tracking additives. Pressed under high-pressure automated hydraulic compression molding machines, these components exceed traditional porcelain and basic epoxy alternatives in mechanical toughness, thermal stability, and dimensional precision.

Providing Unmatched Reliability for Switchboard Builders, OEMs, and EPC Contractors
In municipal and commercial electrical installations in Bucharest, Brașov, and Ploiești, SB 14-20 standoff insulators secure main copper busbars inside distribution boards (PCC and MCC panels). They protect systems from phase-to-phase flashovers under sudden voltage spikes and short-circuit electrodynamic forces.
Romania’s rapidly growing solar power parks in Giurgiu, Dolj, and Olt counties require specialized DC busbar isolation. SB Series insulators feature high insulation resistance (up to 1TΩ) and long creepage distances, preventing surface tracking in outdoor power conversion enclosures.
For industrial hubs in Timișoara, Cluj-Napoca, and Arad, industrial automation drives and frequency conversion switchboards demand insulation parts resistant to high vibration, continuous heat, and oil fumes. SB insulators deliver rigid vibration damping.
Zhejiang Flyaford Electron Co., Ltd. — Pioneering Composite Insulation Excellence Since 2007
Situated in the Jinyi New District of Jinhua City, Zhejiang Province, Zhejiang Flyaford Electron Co., Ltd. spans a state-of-the-art construction area of 35,000 square meters.

As EU regulations phase out sulfur hexafluoride (SF6) gas in medium-voltage switchgear due to high global warming potential, modern dry-air and eco-gas insulated switchboards are replacing them. Flyaford is developing ultra-low outgassing BMC compounds designed specifically for dry-air insulated medium-voltage enclosures up to 24 kV.
With smart grids taking center stage across Romania's distribution network, Flyaford’s R&D center is testing SB series insulators embedded with micro-passive temperature sensors. These smart insulators report real-time busbar thermal stress and hot-spot detection directly to digital SCADA systems.
