The outlet type bell mouth copper terminal block is applicable to the connection between the copper conductor of power cable type wire with a nominal section of 1.5-630MM and the electrical equipment. It is made of high-purity T3 copper tube with a copper content of more than 99.4%, and the product surface is tinned. The peeping horn mouth type copper tube terminal is made of high conductivity T2 copper tube by stamping Seamless copper tubes provide high strength mechanical properties such as tensile extension. Thickened copper tubes can avoid cracking or deformation caused by mechanical crimping The design with inspection hole can clearly observe whether the incoming line is in place so that users can make adjustments in time Optimized chamfering treatment is adopted at the end of the copper tube, which can make the incoming line easier on the one hand, and disperse the stress generated by crimping on the other hand. The surface is environment-friendly electrolytic tin plating, and the conventional coating thickness is 3-6 μ m .
