The principle of insulating tape
There are many disadvantages to using plastic tape directly: plastic tape is prone to dislocation and glue opening for a long time; when the electrical load is heavy, the connector is heated, and the plastic tape is easy to melt and shrink; the power connector is squeezed against each other in the junction box. Injury plastic tape, etc.
These hidden dangers will directly endanger personal safety, cause short circuits, and cause a fire. The above situation does not occur when using insulating black tape. It has certain strength and flexibility, can be wrapped around the joint for a long time, and is compacted and shaped by the influence of time and temperature. It will not fall off and is flame-retardant. Furthermore, it can be protected from moisture and rust by wrapping it with insulating black tape and wrapping it with plastic tape.
Of course, the insulating self-adhesive tape also has defects. Although it has good waterproof performance, it is easy to break. Therefore, it is necessary to wrap two layers of plastic tape as a protective layer. The insulating self-adhesive tape of the joint and the joint is non-sticky to each other and has better performance.
