Product details of Osaka PVC Tennis Ball Tape & Electric Tape (Black)

Description

These primary tapes used in electrical applications are vinyl, rubber, mastic, and varnished cambric.
Electricians generally use only black tape for insulation purposes, but other colour's are also required.
The other colors are used to indicate the voltage level and phase of the wire. (In fact, the colored tape is referred to as phasing tape.)
This is done on large wire which is available only in black insulation.
When wires are phased, a ring of tape is placed on each end near the termination so that the purpose of the wire is obvious.
This is the best fitted for outdoor use due to its durability and weather resistance.
What's important to remember though is that you need to use the right tape when covering up wires.
These tapes are made of rubber-based adhesive that helps it stretch.
These are used for different purposes but mostly in electrical applications such as on wires etc.
