In the electricity process, people note that the size of the cross-sectional area of ​​the power cord material on the safe use of electricity have an impact, but often the use of vpi mica tape is not enough attention. Power lines are now more and more complex, walking under the wood floor, walls, partitions and damp 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 disconnected, it should be wiped with a steel wire, and then wound around the mouth, and then swing around, the thread will be quickly in the connector at the break. If the joints in the dry place, 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 mica insulation 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 connectors in the junction box with each other pressure, Easy to stamp the 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 long-term, by the 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, bakelite sheet suppliers 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.
