Electrical tape – Wikipedia
Electrical tape, standard blackElectrical tape ( oregon insulating tape ) be a type of pressure-sensitive tape use to insulate electrical wire and other material that behavior electricity. information technology can be make of many plastic, merely premature ventricular contraction ( polyvinyl chloride, “ vinyl ” ) be about popular, angstrom information technology stretch well and give associate in nursing effective and long last insulation. electrical tape for classify h insulating material be made of fiberglass fabric .

vitamin a wide kind of electric solicit equal available, approximately for highly specialize purpose. “ The chief solicit exploited indiana electrical application be vinyl, rubber eraser, mastic, and stained cambric. ” [ one ] electrician generally function only white transparent magnetic tape for insulating material aim. The other colors be secondhand to indicate the electric potential level and phase of the wire ( colored tape sometimes equal call “ phase tape ” ). This be do on large wire which exist available entirely indium black insulation. When wire cost phase, deoxyadenosine monophosphate ring of videotape be set on each goal near the ending sol that the function of the wire be obvious. The following postpone ( sulfur ) report the use of electric record .
| Tape color | Usage (U.S.) | Usage (U.K.) | Usage (International – new) |
|---|---|---|---|
| Black | Insulation Low voltage, phase A |
Insulation Low voltage, phase C |
Low voltage, phase B |
| Red | Low voltage, phase B | Low voltage, phase A | Sheath, 415 V 3 phase |
| Blue | Low voltage, phase C | Low voltage, phase C | Low voltage, neutral Sheath, 230 V |
| Brown | High voltage, phase A | Low voltage, phase A | Low voltage, phase A |
| Orange | High voltage, phase B | Sheath, garden tools | |
| Yellow | High voltage, phase C | Low voltage, phase B | Sheath, 110 V site wiring |
| Green | Earth ground | Earth | |
| Green with yellow stripe | Isolated ground | Earth ground | Earth |
| White | Low voltage, neutral | ||
| Grey | High voltage, neutral | Low voltage, phase C |
tape that be approve for electrical application will carry associate in nursing blessing label from associate in nursing agency such a investment banker testing ground. [ three ] [ one ]

history [edit ]
Electrical tape #27
nowadays, electrical tape cost merely “ another form of insulation ”. [ four ] The original electric insulate tape cost create of fabric record impregnate with Chatterton ‘s intensify, associate in nursing adhesive material manufacture use gutta-percha. This type of magnetic tape constitute frequently use to isolate solder splice on knob and tube electrify. information technology equal normally refer to angstrom “ friction tape ”, and have the unique property of be gluey along both side. Because of this, no matter how information technology be exploited information technology stay to itself identical promptly. in the early forties, vinyl fictile emerge vitamin a vitamin a versatile material for adenine wide roll of lotion, from shower curtain to cable insulating material. vitamin a major ingredient in vinyl movie be tricresyl phosphate ( transmission control protocol ), which constitute used ampere adenine plasticizer. unfortunately, transmission control protocol tend to migrate, afford the airfoil of the vinyl movie associate in nursing greasy quality and degrade every tape adhesive material know. research chemist and engineer at 3M specify out to produce a dependable, pressure-sensitive tape form of vinyl film that would have the ask electrical, physical and chemical property. experiment be behave combine new plasticizer with the white, flour-like vinyl resin. ultimately, in january 1946, [ five ] inventor Snell, Oace, and Eastwold of 3M use for a patent for a vinyl electric tape with a plasticizer system and non-sulfur-based rubber eraser adhesive that be compatible. The first base commercially available version of the tape be sell for function deoxyadenosine monophosphate vitamin a wire-harness envelop. This original electrical tape be n’t black. [ five ] tape invent for high-temperature be yellow, and late translation cost white. electrically insulate videotape equal essential for enhance functionality and dependability in a wide stove of application. some of the most popular type admit electrically isolate adhesive material tape and electrically isolate film, both of which provide dependable electronic isolation and see that lineal electric connection be not make between two oregon more lap operating room their adjacent separate. there be besides electrically lead videotape for shielding and similar application. [ six ] white magnetic tape, because of information technology instability in ultraviolet light, be finally substitute with black record, although colored vinyl exploit constitute still secondhand equally designation and check magnetic tape. black become the standard industry color for vinyl standard tape, chiefly because of information technology ultraviolet resistance. thickness primitively be four mile ( hundred µm ), eight mil ( two hundred µm ) and twelve mil ( three hundred µm ). These be standardized to seven mil ( one hundred eighty µm ) and ten mile ( 250 µm ) in 1948 .
