When we first installed a metal shredder machine, wiring was a very important part. Since metal shredder machines usually only use lead cables at the factory, users need to reconnect the cables separately when installing the cables. Therefore, please pay attention to the correct method when connecting the cables. Otherwise, it will have a significant impact on its use.
Let's take a look at the cable connection method of the metal shredder machine: strip the copper core of the cable about 30-35mm long from the metal shredder machine, and then wipe the copper wire with an emery cloth to make it shine. Peel off the copper wire of the external three-core cable by 30-35mm, and then wipe it with an abrasive cloth.
Insert the three-core cable and the copper wire stripped from the external cable. Then tie it tightly with a thin copper wire. Cut off the rest and use a pair of scissors to prevent it from being restrained. The three wire heads are welded separately, the surface of the head is smooth, no burrs, and welding errors. If not, it should be re-welded. Until the requirements are met. Squeeze half with polyester insulation tape. (Half-layer dressing method) 8-12 layers of dressing after bandaging. Then wrap the two layers with plastic tape to increase strength.
Wrap three heel wires with plastic tape, and wrap two layers more than 50 mm at the end of the insulation of each wire. After bandaging, take a pot of cold water and immerse the wrapped thread in water. After 12 hours, use a 500V megohmmeter to measure insulation of not less than 50 megohms. Otherwise, it should be repackaged until it meets the requirements.
The ground wire of the metal shredder machine must also be bundled according to the requirements of the submarine cable connection process. After connecting the wires, keep shaking the insulation resistance while observing the changes to prevent the cable wall from damaging the cable insulation. If the insulation level drops below 0.5 MΩ, it should be placed to detect the cause.
