The Importance of Elongation in Electrical Tapes

February 11, 2021

Electrical tape is a significant piece of any electrical technician’s tool stash. It is utilised to cover and insulate a wide assortment of electrical wires and links just as distinguish them by voltage level and stage.

Since the electrical tape is utilised day by day by those in the field, it assumes a fundamental part of maintaining electrical wellbeing. What’s more, much the same as with other wellbeing items, you should understand what you are looking for while selecting the appropriate electrical tape.

What is Elongation and Why is it Important?

A critical trademark for selecting a top-notch tape is elongation. Elongation is the proportion of how far the tape can extend before it breaks. Knowing the elongation rating (estimated in rates) will reveal to you how well it can deal with the continuous pressure of being extended, whenever it is applied.

Elongation is a vital trademark to search for while choosing an electrical tape since stretch is a significant piece of the way toward applying the tape in a splicing or phasing task. In electrical applications, the most ideal approach to guarantee a watertight and secure seal is to extend the tape as you fold it over the link so when you are finished, the wrapped tape normally needs to get back to shape, maintaining a solid grasp. The capacity to get back to shape is identified with elongation and will in general increase with the evaluation and nature of tape utilised. A tape with helpless elongation may break effectively while being applied, resulting in lost time, squandered tape, and dissatisfaction.

With regards to sealing out contamination and dampness in basic applications, an excellent tape will offer you the elongation properties vital. At the point when you stretch the tape to apply it to the wires, it will normally need to contract back to its original state, forming a “living memory.” This is vital because the living memory is the thing that keeps the tape firmly got to the wire, blocking out the dampness and contamination.

Here several strategies for testing elongation that you can perform with little exertion at home or in the field:

Take a piece of electrical tape, stretch it, and apply it around your finger as though you were wrapping a piece of wire. On the off chance that you feel the tape quickly tightening, then that is a decent indicator.

Append in any event a 2-inch portion of the tape to a table, hold the end joined to the table while stretching the flip side outwards, to about twofold its length, and afterwards let go. If the tape rapidly withdraws back to its original structure, that is a decent indicator.
