What is the purity and conductivity of the copper material of the copper bolt mechanical lug?

Our copper bolt mechanical lugs are made of high-purity copper. The copper content of high-purity copper is generally above 99.9%, and the common grade is C11000 electrolytic copper. This high-purity copper has an extremely low impurity content, which ensures excellent conductivity and oxidation resistance.

We offer two versions of contact bolts: removable/non-removable. The inner surface of the conductor hole is grooved. The lugs are suitable for outdoor and indoor applications and are available in different palm hole sizes. The mechanical connectors for direct connectors and transition connectors are available in unblocked and blocked types.

Processing technology:

During the production process, shear bolt connector are usually subjected to strict smelting and rolling processes to ensure the purity and uniformity of the copper material. These processes include electrolytic purification, hot rolling, cold rolling and other steps, which further improve the purity and performance of the copper material.

1. Conductive performance:

Copper has an extremely high conductivity, second only to silver, and is one of the most commonly used conductive materials. The electrical conductivity of high-purity copper is about 5.8×10^7 S/m, and its conductive properties are excellent, making it suitable for a variety of electrical connection applications.

Low resistivity: The resistivity of high-purity copper is about 1.68×10^-8Ω·m, which means that at the same current intensity, copper will produce less voltage drop and heating effect. This is essential to maintain the stability and efficiency of the electrical system.

Temperature stability: The conductivity of high-purity copper changes little at different temperatures, and it can maintain stable conductivity over a wide temperature range. This performance of shear bolt lug mechanical lug is particularly important for electrical equipment that needs to operate for a long time.

2. Application advantages

**Reliable electrical connection**: Due to the excellent conductive properties of high-purity copper, bimetallic shear bolt lug can provide reliable electrical connections, reduce contact resistance, and improve the operating efficiency of the system.

**Durability and stability**: High-purity copper has good anti-oxidation and anti-corrosion capabilities, and can be used for a long time in harsh environments, ensuring the durability and stability of the lugs.

**Diverse applications**: Copper screw mechanical lugs are widely used in power, electrical equipment, industrial automation and communications. Due to their excellent conductivity and mechanical properties, they have become the first choice for various high-demand applications.

3. Quality inspection and standards

**Quality inspection**: To ensure the purity and conductivity of copper materials of lugs, manufacturers usually conduct strict quality inspections. These inspections include chemical composition analysis, conductivity testing, mechanical property testing, etc. to ensure that the products meet relevant standards.

**Industry standards**: The production and inspection of lugs usually need to follow international and national standards, such as IEC (International Electrotechnical Commission) standards and ASTM (American Society for Testing and Materials) standards. These standards specify parameters such as copper purity, conductivity, and mechanical properties to ensure product quality and consistency.

Lugs have significant advantages in electrical connections due to their high-purity copper material and excellent conductivity. High-purity copper material ensures low resistivity and high conductivity, and can provide reliable and stable electrical connections. At the same time, its good durability and stability make it suitable for various harsh application environments. Through strict quality inspection and compliance with industry standards, lugs can meet the high requirements of various electrical applications, ensuring the efficient operation and safe and reliable operation of the system.
