In the field of industrial motors, the reliability of insulation systems directly impacts the stable operation of entire production systems. As a professional manufacturer of motor insulation mica tape, NBRAM once provided insulation solutions for the giant hydro-generators at the Three Gorges Power Station. These generators operate in environments where humidity consistently exceeds 85%, posing severe challenges to insulation materials. Our developed epoxy resin-impregnated mica tape demonstrates exceptional anti-hydrolysis characteristics while maintaining excellent insulation performance. Through five years of continuous operational monitoring, the insulation resistance values have consistently remained above design standards. This long-term stability has made our products the preferred insulation material for large hydropower projects. Our Motor Insulation Mica Tape series includes Double-Side Reinforced Mica Tape, Single-Side Reinforced Mica Tape, etc.
We deeply understand the specific requirements of different motor types for insulation materials. To address corona discharge issues in high-voltage motors, we innovatively composite a nanometer-grade silicon carbide coating on the mica tape surface, extending insulation life over threefold. For high-temperature motors in the metallurgical industry, we employ silicone resin binders to ensure the mica tape maintains sufficient flexibility and bonding strength even at 200°C. Notably, our ultra-thin mica tape developed for new energy vehicle drive motors, with a mere 0.08mm thickness, can withstand continuous voltage of 1500V, successfully solving insulation design challenges in compact spaces. These technological innovations all originate from our deep collaborations with motor design engineers.
Currently, NBRAM motor insulation mica tape has obtained UL and CE certifications, complying with IEC international standards. We maintain long-term partnerships with industry leaders like Shanghai Electric and Dongfang Electric, with our products exported to Europe, Southeast Asia, the Middle East and other regions alongside motor equipment. Our new intelligent coating production line achieves precise composite of mica paper, fiberglass cloth and resin, with thickness deviation controlled within ±0.01mm. Every roll of mica tape undergoes 12 rigorous tests including breakdown voltage, bond strength, and volatile content. Recently, we've been collaborating with a renowned German motor manufacturer to develop a new generation of eco-friendly mica tape, reducing VOC emissions to one-third of traditional products while increasing corona resistance life fivefold. Choosing NBRAM means opting for insulation safety that stands the test of time.
You know that moment when you're running cable production and the insulation tape just won't hold up under pressure? That exact frustration is what drove us to develop our double-side reinforced mica tape with real-world manufacturing challenges in mind. At NBRAM, we've spent years working alongside electrical manufacturers, understanding their daily struggles with insulation materials that either offer great dielectric properties but poor mechanical strength, or vice versa. Our breakthrough came when we realized that true innovation wasn't about choosing between properties, but about achieving both simultaneously.
Let me tell you, after twenty years wrestling with insulation tape that just wouldn't cooperate, NBRAM's Single-Side Reinforced Mica Tape feels like someone finally listened to what we electricians actually need. The glass fabric backing gives you something solid to work with - no more tape twisting or tearing when you're trying to wrap tight corners. I've used this stuff on everything from furnace transformers to elevator motors, and it just works. If you're tired of fighting your insulation materials, order this tape from NBRAM and actually enjoy your next motor rewind.
When your high-voltage motors are on the line, NBRAM's specialized Mica Tape For High-Voltage Motor Winding is the difference between reliable operation and costly downtime. I've personally used this tape in 6.6kV motor rewinds where it handled voltage spikes that would have fried ordinary insulation. If you're sourcing winding tape that can take the punishment of industrial high-voltage applications, this is what you need to order from NBRAM today.
