Electrical tapes are designed to insulate the electricity-conducting wires or other materials that carry electrical currents. They protect the people and other components by preventing power transmission of a wide variety of wiring by insulating them. They feature an adhesive backing for applying to cables that protect against fire hazards, electric shocks, UV radiation, dust, moisture, dirt, and a range of solvents. Furthermore, they are resistant to abrasion and are flame retardant and used when installing or repairing electrical wiring. Additionally, they come in varied thicknesses, widths, materials, and colours that suit a range of specific applications.
What are the Alternate Names for Electrical Tapes?
These tapes are also identified as insulation tapes, PVC tapes, thermal tapes, insulating tapes, or electrical insulation tapes.
Colours of Electrical Tapes
Electrical tape comes in multiple colours and combinations that are used to mask them and code the voltage levels and phases of the specific wires (phasing tapes). The following are the insulating tape colours.
- Black
- Blue
- Red
- Yellow
- Green
- Grey
- Brown
- White
- Green/Yellow.
Colour Codes of Electrical Tapes in the UK
In the UK, each colour denotes different voltage and phase levels of the wires, such as brown tape showing low-voltage live wires, blue tape representing low-voltage neutral wires, whereas green denotes the protective earth (PE) wire.
Electrical Tape Materials
Electric tape is commonly made of vinyl as it stretches well and provides long-lasting insulation for electrical wiring. However, they can also be constructed from plastic, such as PVC.
Types of Electrical Tapes
Insulation tapes are classified into the following types based on their ability to provide insulation resistance, extreme temperature capabilities, and dielectric breakdown.
- Conductive Tapes- made from conductive materials, these insulating tapes are ideal for shielding distinct varieties of electrical connections along with the high-voltage splices insulation and rebuilding strand.
- Electrical antistatic tapes – Suitable for use near electronic components and assemblies. They produce a minimum amount of voltage upon removal, minimizing the risk of damage caused by electrostatic discharge.
- Glass cloth tapes –with high mechanical strength and the ability to withstand exceeding temperatures, also feature excellent varnish and resin absorption properties.
What are the Typical Applications of Electrical Tapes?
Depending on the type of electrical insulating tape, they are typically employed for the insulation purposes of electrical wiring. For instance, black electrical tape is ideal for low-voltage neutral uses. They are used by professionals like electricians and engineers during the:
- Electrical Installation
- Electrical Maintenance
- Isolation between conductors in electronic devices (computers, telephone boxes)
- Automotive Repair.
