Product Description

 
Product Description
 
Silk-covered wire refers to an electromagnetic wire formed by wrapping one or two layers of natural or synthetic fibers over an enameled stranded wire. Common types include polyester fiber-covered wire, nylon fiber-covered wire, and self-bonding fiber-covered wire (acetone-bonded or hot-air bonded).
Type Silk Layer Material Processing Method Key Properties
USTC Polyester, Polyamide Single-layer silk wrapping Heat resistance class 130
UDTC Polyester, Polyamide Double-layer silk wrapping (tight, nocopper exposure) Heat resistance class 130
UDATC Polyester + AcetateFiber Double-layer silk wrapping (tight, nocopper exposure) Heat resistance class 130, acetone solvent bonding, strong adhesion, rapid coil fomming
UDHTC Polyester + PolyamideFiber Double-layer silk wrapping (tight, nocopper exposure) Heat resistance class 110, hot-air bonding (110-140C), strong adhesion, rapid coil forming.environmentally friendly
Advanced Silk Coated Enameled Wire for Aviation Needs
Features & Advantages:
1:Excellent high-frequency resistance.
2:Neat coil winding arrangement with high Q-factor.
3:Superior to enameled stranded wires: Silk protection minimizes wire damage during winding, ensuring enhanced electrical performance.
4:Self-bonding silk-covered wires offer high adhesion, rapid forming, and eco-friendliness (hot-air bonded type).
5:Excellent direct solderability with minimal residue.
6:Customizable production based on client requirements (wire diameter, structure, etc.).

Applications of Silk-Covered Wires:

  • High-Frequency Electronics: RF inductors, high-frequency transformers, 5G communication modules.

  • New Energy Systems: Solar inverters, EV charging coils, wind turbine generators.

  • Consumer Electronics: Wireless chargers, drone motors, smart device coils.

  • Industrial Equipment: Welding machine coils, motor windings, solenoid valves.

  • Medical Devices: MRI system coils, electrosurgical tools, diagnostic equipment.

  • Aerospace & Defense: Avionics wiring, satellite communication components, radar systems.
