Cotton Covered Copper Conductor

Cotton Covered Copper Conductors are insulated copper wires that use natural cotton yarn as a primary insulating layer. These conductors are especially valued in vintage, restoration, and specialty applications, as well as in high-temperature and low-voltage equipment. The cotton layer provides mechanical strength, basic electrical insulation, and resistance to heat and abrasion, making it ideal for specific industrial and decorative uses.

Construction:

• Conductor: High-conductivity, annealed or hard-drawn bare copper or tinned copper

• Insulation: One or more layers of cotton yarn tightly braided or wrapped over the conductor

• Finish Options: May be treated with wax, varnish, or enamel to enhance moisture resistance and durability

Key Features:

• 🧵 Natural Cotton Insulation – Flexible, breathable, and abrasion-resistant

• 🔥 Good Heat Resistance – Suitable for moderate temperature environments

• 🛠️ Flexible and Easy to Handle – Ideal for winding and manual installation

• 🎨 Aesthetic Appearance – Often used in visible or retro-style electrical work

• ⚡ Decent Electrical Insulation – Suitable for low-voltage or secondary applications

Applications:

• Transformer and Motor Windings

• Antique and Vintage Wiring Restoration

• Low-Voltage Coils and Circuits

• Lamps, Light Fixtures, and Decorative Wiring

• High-Frequency Equipment and Radios

• Textile and Automotive Components

Advantages:

• ✅ Eco-Friendly and Biodegradable Insulation

• ✅ High Flexibility and Bend Radius

• ✅ Customizable Colors and Patterns

• ✅ Non-Toxic and Safe for Light Electrical Use

• ✅ Reduced Static Build-Up in Certain Environments

Specifications:

• Conductor sizes typically range from 0.2 mm to 2.0 mm diameter

• Available in single or double cotton covering

• Can be supplied as bare, tinned, or enameled copper base.

Limitations:

• Not suitable for high-voltage or harsh environmental applications

• Cotton may degrade over time if exposed to moisture or chemicals

• Should be handled with care in flammable or oil-laden environments unless treated
