Hard-drawn copper bar is an important part of electrical equipment, used to provide a grounding function, transfer current, and ensure the safe operation of the equipment. In different application scenarios, the requirements for grounding the busbar and material selection are not the same. This article will introduce the grounding busbar commonly used several materials and their applicable application scenarios. Copper: copper is a common grounding busbar material, with excellent conductivity and good stability.
1. Copper grounding busbars made in demanding applications, such as high-voltage power systems or the quality of grounding have strict requirements of electrical equipment is widely used. Copper has better conductivity and can provide a stable grounding effect, but the cost is higher compared to other materials.
2. Aluminum: Aluminum is also a commonly used grounding busbar material, it has good electrical conductivity and relatively low cost. Aluminum grounding busbars in some low-voltage power systems are widely used. Compared with copper, aluminum conductivity is slightly worse, but its lightweight features make it an economical and practical choice.
3. Stainless steel: stainless steel has good corrosion resistance and high mechanical strength, suitable for special environmental conditions, such as high temperature, humidity, or corrosive places. Stainless steel grounding busbar can provide a stable and long-lasting grounding effect, to protect the safe operation of equipment.
4. Pure silver: pure silver is one of the best conductive materials, with excellent conductivity and corrosion resistance. Pure silver grounding busbar is mainly used in the field of very high conductivity requirements, such as high-precision electronic equipment, and communications equipment. However, the production cost of pure silver material is higher, commonly used in some of the grounding effects of very strict requirements of the occasion.
