Wenzhou aluminum gasket, aluminum washer, aluminum sealing gasketAttention requirements:

Copper and aluminum cannot be directly welded, it's not that they can't be welded together, but that welding will produce electrochemical reactions after being electrified, which can be dangerous!!
Some copper aluminum transition parts work by forming a copper aluminum alloy at the welding point.

The "Code for Construction and Acceptance of Busbar Devices in Electrical Equipment Installation Engineering" clearly stipulates that when busbars are overlapped with busbars, busbars with branch lines, and busbars with electrical wiring terminals,Wenzhou aluminum gasket, aluminum washer, aluminum sealing gasketThe treatment of overlapping surfaces should meet the following requirements:

(1) Copper and copper: Tin coating must be applied outdoors, in high temperature and humid environments, or indoors with corrosive gases to the busbar; It can be directly connected indoors in a dry environment.

(2) Aluminum and aluminum: directly connected.

(3) Copper and aluminum: Copper conductors should be tinned in dry indoor environments. For outdoor or indoor environments with similar relative humidity, copper aluminum transition plates should be used, and the copper ends should be tinned. Correspondingly, copper aluminum connection pipes can be used to connect copper cables with aluminum cables, and copper aluminum terminals can be used to connect copper cables with aluminum wires. The copper end should be tinned, etc.
With the increasing replacement of copper with aluminum in the power system, poor contact caused by corrosion at the contact between aluminum and copper has emerged
Heating, sparking, increased resistance, equipment accidents, increased maintenance frequency, and other adverse phenomena that affect safe operation
If a strong aluminum copper transition joint is used at the joint, these problems can be effectively solved
Currently, likeAluminum gasket, aluminum washer, aluminum sealing gasketThe commonly used aluminum copper transition joints in the market are mostly flash welded products However, due to the complexity of the flash welding process, it is necessary to
Large equipment is required, resulting in high product costs and narrow usage range Based on this situation, our company refers to domestic and international standards
Based on our experience, we have successfully developed an aluminum copper transition joint using the explosive welding technique
