Our double insulated sleeve is made using composite materials including high heat resistant resin and alkali-free glass fiber in accordance with scientific formula and specific manufacturing techniques. It has characteristics such as high mechanical strength, high dielectric permittivity, and high corrosion resistant, as well as excellent anti-fatigue properties. Based on these features, this product can find its widespread applications in various electrical equipment, motors, and electrical tools for shaft insulation function. To sum up, the advantages of this product include:
1. This is a high quality product. It comes with high mechanical strength, high size precision, and small inner and outer diameter tolerance (within ±0.0150mm), as well as high withstand voltage of 6.8KV (the highest standard at home and abroad: 5KV).
2. Our double insulated sleeve can be directly assembled to shafts, which simplifies assembly process and reduces assembly cost.
3. Our product is eco-friendly, without dust produced by BMC materials. So, it will do no harm to people and their surroundings.
4. In addition, this product is compliant with ROHS standards.
