Features of Copper Coils
Electrical Conductivity: Copper is one of the most conductive metals, making copper strip tape an ideal choice for applications that require efficient electrical conductivity. It allows the smooth flow of electric current, minimizing resistance and power loss.
Corrosion Resistance: Copper exhibits excellent corrosion resistance, which helps maintain the integrity and longevity of the power cable. This resistance ensures that the copper strip tape remains stable and conductive over time, even when exposed to moisture or other corrosive elements.
High Ductility: Copper coil is highly ductile, meaning it can be easily shaped, bent, or formed without losing its structural integrity. This property allows for convenient installation and ensures that the tape conforms to the desired shape or contour of the power cable.
Thermal Conductivity: Copper is not only an excellent electrical conductor but also a great thermal conductor. This property allows copper strip tape to efficiently dissipate heat generated within the power cable, preventing overheating and potential damage.
Strength and Durability: Copper coil possesses good mechanical strength, enabling it to withstand various stresses and strains encountered during cable installation and operation. Its durability ensures that the tape remains intact and provides reliable electrical connectivity.
Easy Solderability: Copper coil is generally easy to solder, facilitating secure connections between the tape and other electrical components or conductors within the power cable. This feature enhances the overall reliability and performance of the cable assembly.
Malleability: Copper coil is highly malleable, meaning it can be easily hammered or pressed into different shapes without breaking or cracking. This property allows for flexibility in designing and manufacturing power cables, enabling customizations to meet specific requirements.
Availability and Cost-effectiveness: Copper is widely available and relatively affordable compared to other conductive materials. This accessibility and cost-effectiveness make copper strip tape a popular choice in the power cable industry.
These features collectively contribute to the widespread use of copper coil in power cables, ensuring efficient and reliable electrical transmission while maintaining durability and longevity.
Different Copper Coils Applications & Useage
1. Electrolytic Tough Pitch Copper (ETP Copper)
Application: ETP copper is the most common grade used in transformer windings due to its high electrical conductivity and excellent thermal conductivity.
2. Oxygen-Free High Conductivity Copper (OFHC Copper)
Application: Used in applications requiring extremely high electrical conductivity and minimal oxygen content to prevent oxidation.
3. Silver-Bearing Copper Alloys (C11000)
Application: Utilized in specialty transformers where enhanced electrical conductivity and corrosion resistance are required.
