Insulating electrical tapes are used in the same kind, but there are waterproof and ordinary insulating tapes. Generally, the life span is about five to seven years. This means that it is indoors. If it is outdoors, it is only about three to five years.
As long as the low-voltage tape is tightly attached, it is forbidden to oil, water, sun, and freeze. It can be used for more than 10 years, and the protective wire will also have a long life. Not to mention the insulating tape. The key is to connect the wires and tighten the tape. Wrap at least 5 layers. The aging of the insulating tape is related to your usage. For example, it will age quickly if it is used under wind and sun, but it will have a longer life when used in a cool environment, so the service life cannot be stated objectively. There must be a prerequisite. Insulating tape is used in the short term. If you want to use it for a long time, use a more professional joint form. Wire and cable joints must reach four unchanged, that is, the mechanical strength is unchanged; the voltage loss is unchanged; the safe current-carrying capacity is unchanged; and the insulation protection is unchanged. After the end of the thread is connected, wrap it with a layer of waterproof tape (waterproof tape, high-pressure waterproof self-adhesive tape). Be sure to tighten it when wrapping, wrap = more than one layer (above 1KV and more than five layers), wrap it with plastic tape for electricians, then Just wrap it with a layer of black tape. There is also a relatively backward method (currently only used for weak current and electronic circuits) that can also achieve the waterproof effect: make a long or square box at the joint, put the joint in the box and fill it with pine glue.
