PN155 Insulation System
The PN155 Insulation Layer is an advanced dual-layer composite insulation system. This structure combines the advantages of different materials to achieve optimization and balance of performance.
| Structural Layer | Insulating Coating | Core Performance |
| Inner Layer | Modified Polyurethane Resin | Features scrape-free solderability; no need to remove the inner insulation during soldering.High electrical insulation strength and low dielectric loss.3. Meets the 155℃ thermal class requirement. |
| Outer Layer | Nylon | High mechanical strength, with excellent wear resistance and scratch resistance.Good chemical resistance.3. Enhances the wire’s moisture resistance and aging resistance. |
Both layers of materials are selected to protect ultra-fine and fragile magnet wires such as 46 AWG.
PN155 features direct solderability. When the wire is used for terminal connection, there is no need for pre-mechanical scraping or the use of corrosive chemical solvents to remove the insulation layer. This simplifies the process and reduces the risk of damaging the conductor. The realization of solderability relies on the rapid and clean thermal degradation of the insulation layer at a specific high temperature. For fine wires ranging from 24 AWG to 55 AWG, the thermal degradation and soldering temperature specified by standards is 390℃.
In the manufacturing process of winding coils and motors, the nylon coating provides crucial mechanical protection. It ensures that the insulation layer maintains its integrity during high-speed friction, guide pulley traction, and tight winding processes. This enhanced mechanical toughness is vital for improving the winding success rate and yield rate of 46 AWG fine wires.
