Main advantages
- fast connection (press, vice, crimping or impact tool)
- minimal transition resistance in comparison with bolting, reducing the cross section of the bas bar without loss of transmission capacity
- invariance of transition resistance when heat cycling
- contact area of the mating parts is several times larger than the original, which provides high-quality electrical and thermal contact with high mechanical strength
- the possibility of joining dissimilar materials, including the possibility of bi-metal, plating parts other metals or polymer sheets (films). When plating by polymers and soft metal DC machining necessary part only.
