In the electricity process, people pay attention to the power line material cross-sectional area of ​​the size of the safe use of electricity have an impact, but often the use of insulation transformer pressboard is not enough attention. Now the power line alignment is more and more complex, walking under the wood floor, the wall, the partition and the wet underground or water are, if the insulation tape used improperly, will produce leakage, endangering personal safety or cause a fire. So how do you use insulating tape correctly?
Power cord connector is divided into "ten" word connection, "one" word connection, "Ding" word connection and so on. Joints should be wrapped around, smooth without thorns. Before the thread is broken, it should be wiped with a steel wire, and then wound around the mouth, and then swing around, the thread will be quickly disguised at the joint disconnected. If the joints in the dry place, you should first use insulated black cloth wrapped two layers, and then wrapped plastic tape (also known as pvc adhesive tape) two layers, and then J-10 insulation self-adhesive tape stretched about 200% Finally wrapped two layers of plastic tape.
Because the direct use of plastic tape a lot of defects: plastic tape a long time easy to glue dislocation, plastic open, electrical load heavy, the joints heat, plastic tape easy to melt shrink; electrical connector in the junction box with each other pressure, Easy to stamp empty plastic tape, etc., these risks directly endanger personal safety, causing the line is moderate, causing a fire. The use of insulating black tape will not appear above, it has a certain strength, flexibility, can be tightly wrapped around the joints, by time and temperature and dry fixed type, will not fall off, and flame retardant. Moreover, wrapped with insulated vinyl tape and then wrapped with moisture, rust.
Of course, the anti static plastic sheet is also defective, although it is waterproof but easy to break, so the last need to wrap two layers of plastic tape for the protective layer, connector and connector insulation self-adhesive tape non-stick, better performance.
