Technical Field
The invention belongs to the field of tin removal and tin coating, and particularly relates to tin removal and tin coating equipment for electrical equipment and a use method thereof.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
The tinned shielding control cable is characterized in that the long-term allowable working temperature of the cable conductor is 70 ℃, and the cable laying temperature is not lower than 0 ℃. The cable should have a permitted bend radius of not less than 12 times the outer diameter of the cable for cables with armor or copper tape shielding structures. For a flexible cable with a shielding layer structure, the outer diameter of the flexible cable should be not less than 6 times. The cable without armor layer should not be less than 6 times of the outer diameter of the cable. The flame-retardant flexible cable for the direct-current cable communication power supply is suitable for power transmission and distribution systems of power supplies of communication offices (stations), high-rise buildings and the like.
In order to improve the strength and avoid copper oxidation and corrosion, tin plating is performed on copper noses (including copper bars and the like) connecting cables and electrical equipment, and the electrical equipment needs to be overhauled or overhauled once in three to five years, and the copper noses (including the copper bars and the like) need to be detached for overhauling so as to perform inspection on the cables, the electrical equipment and the copper noses. The detached copper noses (including copper bars, etc.) will have tin, which is generally oxidized. If the copper nose (including copper bars and the like) is needed to be used again, tin oxidized on the copper nose (including copper bars and the like) needs to be removed, and then tin is re-plated when the copper nose is used again.
It can be seen that the prior art lacks a device integrating tin removal and tin plating.
