The ground wire of the tire shredder must also be bandaged according to the requirements of the diving cable connection process
When we first installed the tire shredder, wiring was a very important part. Because the tire shredder usually only uses lead cables when leaving 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 big impact on its use. Let's take a look at the cable wiring method of the shredder machine:
Strip the copper core of the cable about 30-35mm long on the shredder machine, and wipe the copper wire with an abrasive cloth to make it shine. Peel off the copper wire of the external three-core cable by 30-35mm, and wipe it clean with an emery 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 ends are soldered separately, the surface of the welding head is smooth, no burrs, and false soldering. If not, it should be re-welded. Until the requirements are met.
Squeeze half with polyester insulation tape. (Semi-layered dressing method) 8-12 layers of dressing, after wrapping. Then wrap the two layers with plastic tape to increase strength. Wrap the three heel wires together with plastic tape, and wrap the two layers more than 50mm beyond the end of each wire insulation layer. After dressing, take a basin of cold water and soak the wrapped thread in water. After 12 hours, use a 500V megohmmeter to measure the insulation not less than 50 megohms. Otherwise, it should be repacked until the requirements are met.
The ground wire of the shredder machine must also be bandaged according to the requirements of the submarine cable connection process. After connecting the wires, continue to shake the insulation resistance while observing the changes to prevent the cable wall from shattering the cable insulation. If the insulation level drops below 0.5MΩ, it should be placed to detect the cause.
