AI Technical Summary

⚠Technical Problem

The linear insulation ends of the generator set stator coils are prone to corrosion in humid environments. Existing winding moisture-proof and heat-insulating layers are inconvenient to operate and difficult to guarantee sealing.

⚗Method used

It adopts a combination structure of wrapping sleeve and overlapping parts. The wrapping sleeve has a flame-retardant layer, a moisture-proof layer, a heat insulation layer and an insulating layer. It can be easily wrapped through the opening seam and the snap-fit ​​structure. The overlapping parts cover the opening seam and are heat-shrink fixed, providing double protection.

🎯Benefits of technology

It improves the protective effect of the straight insulation end, reduces moisture ingress, ensures the dryness of the insulation end, simplifies the operation process, and improves the sealing and wear resistance of the winding.
