If you are in manufacturing, then you know how important stability and heat resistance are.

• Copper foil serves to:
• transformer windings
• motor insulation
• heat exchangers
• HVAC equipment
• making coils
• heavy-duty wiring

High-quality copper foil enhances efficiency by reducing resistance, thereby preventing overheating.

3. Earthing & Electrical Safety Systems

This is one area where quality should never be compromised.

• Copper foil is used in:
• chemical earth rod
• copper earthing rod
• earthing rod copper
• copper chemical earthing
