Electricians usually use black colorer insulation tapes. The colours of insulation tapes are used to mark voltage level and phase of the wire. Insulation tapes in sri lanka also comes in various sizes and thickness. They are commonly known as phasing tapes in sri lanka. insulation tapes works with wide range of cables, wires and materials that conduct electricity. Most pvc insulation tapes have decent thermal properties and heat-resistant and fireproof up to 80 Celsius. However most tapes will be flammable if they get hot enough. In most insulations combustion is very low. Usually PVC wire insulation tapes should be used for insulation of low voltage cables and very low temperature applications. Most pvc wire insulation tapes in sri lanka can handle hard weather conditions, so these are ideal for outdoor wiring.Black Electrical Insulation Tape, mostly used by electricians, home, office, DIY for insulation of wires and connections. White Electrical Insulation Tapes signify ‘low voltage, neutral. Blue Electrical Insulation Tape indicates ‘low voltage 230V’. Green Electrical Insulation Tape signifies ‘earth’ wire. Brown Electrical Insulation Tape indicates ‘high voltage, phase A’. Yellow Electrical Insulation Tape indicates ‘low voltage, phase B’ 110V. Red Electrical Insulation Tape indicates ‘low voltage, phase A’ 415V 3-phase’. Grey Electrical Insulation Tape indicates ‘low voltage, phase C’. PVC tapes also offers an excellent protection against corrosion and gives complete environmental, mechanical and electrical protection used for outside and underground applications.
