Today various types of electrical tapes are available in the market. Most of them are used especially for a specific purpose of insulating electrical wires. Normally black colored electrical tapes are used by electricians for the purpose of insulating the exposed electrical wires. But you can find electrical tapes in a variety of colors. The usage of PVC electrical tapes depends upon their colors. Electrical tapes of different colors are used for insulating wires carrying electrical current with different levels of phases and voltage.
Actually electrical tapes of different colors are known as Phasing tapes as they are used to insulate wires with different phases and voltage or current. The colored tapes are also used at the end of the wires carrying electrical currents of different phases and voltage to recognize them easily. In this way, PVC electrical tapes can be used not only for insulating the electrical wires but also to identify the quality and type of electrical current running through them.
Usage of electrical tapes according to their color code
· Black colored PVC electrical tape is largely used for insulating electrical wires
· The red-colored tape is used on wires with low voltage phase A or B current
· Blue colored tape is used on wires with low voltage phase C current
· Brown colored tape is used on wires with High voltage, phase A current
· Orange colored tape is used on wires with High voltage, phase B current
· The yellow-colored tape is used on wires with High voltage, phase C current
· Green colored tape is used on wires used for Earth ground
· Green with yellow stripe tape is used on wires used for Isolated ground
· The white-colored tape is used on neutral wires or carrying Low voltage current
· Grey colored tape is used on neutral wires or carrying High voltage current
How PVC electrical tape is made
Initially, electrical tapes were made from different types of materials like rubber, vinyl, varnished cambric, and mastic, etc. but today they PVC electrical tapes are made by using PVC or polyvinyl chloride because it provides good insulation, lasting stickiness, and variety of tapes at an affordable price. Moreover, PVC tapes can be used effectively in the surroundings with a temperature of fewer than 80 degrees C due to its good tolerance for temperature. PVC tapes of different colors are usually used for insulating different types of wires carrying electrical current at different levels of voltage and phases, as mentioned above. They are also packed differently according to the requirements of their users.
However, you should also keep in mind that PVC electrical tapes are not made of the only PVC as a coat of rubber sensitive adhesive is also coated on them as a backing material. This material is important to use on these tapes to provide the strength and avoid their needless breakage. It also makes the tape resistant to high voltage and extreme weather conditions. PVC electrical tapes are normally available in different lengths and widths like 5, 10, and 20 yards or 5, 10 and 20 meters in length and 12 to 50mm in width so that you can choose from them as per your requirement.
Difference between PVC electrical tapes and insulation tapes
Normally PVC electrical tapes are also considered as insulation tapes but it is a wrong conception. The difference between these two types of tapes is briefly described hereunder for your consideration.
PVC electrical tapes are made of the soft film of PVC and rubber-coated with pressure-sensitive adhesive. This tape has good resistance from flame, cold and voltage as well as good insulation properties. It can also be used for insulating wire winding and automotive wiring. Electrical tapes made of a film of polyester coated with solvent-based pressure-sensitive adhesive are also used for insulating electrical wires due to their resistance to high temperatures and high tensile strength.
On the other hand, the base of insulation tapes, normally used for insulation and preventing leakage, is made from different types of materials like synthetic fabric, cotton cloth, and plastic film, etc. The base tape is coated with a layer of pressure-sensitive adhesive. Though these tapes offer good pressure resistance, insulation, weather resistance, and retardance to flame you cannot rely on them for insulting electrical wires.
Thus, PVC electrical tapes can be used not only insulate electric wires but also to recognize them.
