What is a Mechanical Lug?
2025-10-13
A Mechanical Lug is a vital component used in electrical and power distribution systems to securely connect cables and conductors. It ensures efficient current transfer and stable connections, even under demanding conditions. In our factory, we manufacture high-quality mechanical lugs designed for reliable electrical performance and long-term durability. Understanding its design, materials, and functions is essential for selecting the right product for your specific application.
Understanding the Function of Mechanical Lugs
Mechanical Lugs are used to terminate electrical conductors to equipment, cables, or bus bars without the need for soldering or welding. They are typically installed using set screws that mechanically secure the conductor. This type of connection provides excellent mechanical strength and electrical conductivity, allowing easy installation and maintenance. At Wenzhou Kangshuai Electronic Co., Ltd., our mechanical lugs are engineered to meet international standards and are suitable for various industrial, commercial, and residential applications.
Types of Mechanical Lugs
There are different types of Mechanical Lugs depending on the installation and conductor type. The most common types include:
2. Two Hole Lugs – Provide enhanced stability and secure connections under vibration or high load.
3. Reducing Lugs – Allow the connection of smaller conductors to larger terminals.
4. Dual Rated Lugs – Suitable for both copper and aluminum conductors, ensuring flexibility in use.
Our product range includes all these variations, enabling our customers to find exactly what fits their needs. The design of each lug ensures maximum electrical contact and minimal resistance loss.
