1results about How to "Does not affect bending" patented technology

This utility model discloses a three-layer insulated wire with a coating, including a wire core. The outer wall of the wire core is wrapped with an enameled layer, and a first insulating layer is wrapped around the enameled layer. A pressure-resistant metal ring is sleeved on the outside of the first insulating layer. A second insulating layer is wrapped around the outside of the pressure-resistant metal ring, and a third insulating layer is wrapped around the outside of the second insulating layer. Beneficial effects: This utility model features a pressure-resistant metal ring, which is a short circular ring positioned between the first and second insulating layers. After the first insulating layer is applied, workers can individually sleeve the pressure-resistant metal rings onto the outside of the first insulating layer. The positioning grooves and positioning strips prevent arbitrary rotation. The metal pressure-resistant rings significantly improve the overall compressive strength, provide good rodent-proof protection, and reduce the probability of deformation and breakage. Furthermore, there is no rigid connection between the pressure-resistant metal rings, so it does not affect large-angle bending, wiring, or use.
