The long-term hazard of insulating electrical tape

Some rural families, after purchasing a piece of electrical insulating tape, were not used much because they were usually used, and they were used for several years. This approach is inappropriate. A long time to put the electrical insulation tape can not be used!

Since the storage time of electrical insulating tapes is generally not to exceed 15 months, and the storage time is long, not only the viscosity is reduced, the adhesive is spilled, but also the insulation performance is greatly reduced. The expired electrical insulation tape is used to wrap the connector or the electrical appliance. The charged parts are dangerous. In addition, since the electrical insulation tape itself has a normal service life, a line or an exposed live part of the electrical insulation tape is used for a certain period of time, it will be aging and failure, must be regularly checked and replaced to prevent insulating tape The worn-out parts are aged, damaged, and lose the effect of insulation protection and leakage, causing short-circuit, electric shock, fire and other serious accidents.

Finally, to remind everyone that the purchase of electrical insulation tape to be stored at 0-30 °C, ventilation, can not be placed near the heat source, nor long-term exposure to sunlight. When in use, it is wrapped in a semi-overlap and wrapped around two layers. In order to make the wrapping uniform and neat, the wrapping should be applied with a uniform enough pulling force.
