Pictures above are cross-sections of aluminum and copper pole on the market now.
1,Applying tin-lead soldering led by BYD；
2,Polymer welding produced by Kelida, headed by the CATL.
Disadvantages of the above two welding methods: limited welding strength; not environmentally-friendly, low efficiency, high waste.
The second picture is the cross-section of Huihua pole, which increases the contact area of aluminum and copper by 3-5 times, and the joint strength also increases geometrically.
1. Less wastage.
2. Effectively reduce the input of welding equipment in the factory.
