Material
High-purity aluminum or aluminum alloy
Bonding Method
The bonding method of enameled aluminum wire first relies on the insulating varnish to solidify on the surface of the aluminum conductor to form a tightly adhered insulation layer. The bonding between the winding layers and the joints can be achieved by hot melt self-adhesion, insulation fixing, or paint stripping welding.
Shape
Standard round, diameters ranging from 0.6mm to 5.0mm.
insulation material
Polyester paint, polyimide paint, etc.
Online Monitoring of Enameled Wire
Micron-level defect hunter: intelligent visual monitoring system
The system combines high-resolution cameras with high-brightness lighting for online machine vision monitoring.
Four cameras achieve 100% surface coverage during high-speed production.
It can detect both cosmetic defects (paint particles, color shift, oil stains) and physical defects (paint scars, indentations, bubbles, felt marks, and foreign matter).
Leveraging pre-trained machine learning models to process images in real time, it accurately classifies defects with missed and false positive rates below 1%.
Precise control of all dimensions: integration of detection and measurement
Supports ±1 μm accuracy measurement of wire width and thickness.
Two-axis high-speed measurement detects bumps and concavities, and a high-energy gauge achieves ±0.05% non-contact length measurement.
The modular design combined with a high-brightness light source allows for flexible configuration and easy maintenance.
Data-driven intelligent manufacturing upgrade: efficiency and quality leap
Defect classification, custom alerts by type and size, and maintenance of size, defect and statistical databases.

Frequently Asked Questions
Q: What payment methods do you accept?
A: We typically accept common international payment methods such as T/T (Wire Transfer) and L/C (Letter of Credit). Long-term customers can negotiate more flexible payment terms.
Q: What if there is a problem with the product I receive?
A: Please contact us immediately upon receipt. We will promptly investigate the cause and provide a return, exchange, or reissue service to ensure your safety.
Q: Do you provide samples?
A: Yes. We provide standard samples for testing purposes, and some samples are provided free of charge. Shipping costs are borne by the customer.
Q: Can you provide OEM or private label production?
A: Yes. We provide OEM/ODM services to many brand customers, and can customize labels, packaging and brand logos.
Q: How does enameled aluminum wire work?
A: Enameled round aluminum wire conducts current through the aluminum conductor, while the varnish provides insulation and protection, ensuring safe and efficient operation of the coil.
Q: What equipment is this conductor suitable for?
A: It is suitable for oil-immersed transformers, high-temperature motors, inverters, and hermetically sealed refrigeration compressor windings.
Q: How do I clean this electrical wire?
A: Use a dry cloth or soft brush to remove surface dust. Avoid contact between sharp tools and solvents and the varnish.
Q: What precautions should be taken when installing enameled aluminum wire?
A: Keep the wire flat during winding, and avoid stretching and excessive bending to prevent damage to the varnish.
Q: Will this electrical wire crack when bent?
A: No. After annealing and varnish protection, it remains safe with a bend radius of ≥5 times the wire diameter.
