Electrical tape (or insulating tape) is a type of pressure-sensitive tape used to insulate electrical wires and other materials that conduct electricity. It can be made of many plastics but PVC (polyvinyl chloride, "vinyl") is the most popular, as it stretches well and gives effective and long-lasting insulation.
The international standard IEC 60446 Basic and safety principles for man-machine interface, marking and identification - Identification of equipment terminals, conductor terminations and conductors was a standard published by the International Electrotechnical Commission (IEC) that defined basic safety principles for identifying electrical conductors by colours or numerals, for example in ...
IEC 61395 Overhead electrical conductors – Creep test procedures for stranded conductors; IEC 61400 Wind turbines; IEC 61427 Secondary cells and batteries for renewable energy storage – General requirements and methods of test; IEC 61429 Marking of secondary cells and batteries with the international recycling symbol ISO 7000-1135
The most common three-phase system will have three hot legs, 208 V to each other and 120 V each to the neutral. An older, but still widely used, high-leg delta system uses three phases with 240 volts phase-to-phase for motor loads, and 120 volts for lighting loads by use of a center-tapped transformer; two of the phases are 120 volts to neutral ...
The fiber unit is covered with a plastic or steel tape, and the whole surrounded with aluminum and steel strands. Individual fibers may be in "loose buffer" tubes, where the inside diameter of the tube is greater than the fiber outside diameter, or may be "tight buffered" where the plastic buffer is coated directly on to the glass.
This allows one to choose single-phase AC power at either 110–120 volts between phase and neutral or 220–240 volts between phase and phase. Since these two modes do not need three phases there is also a dark yellow-orange four-pin connector available designed for a single-phase 110–120 or 220–240 volt load.
Tape-automated bonding: Variation of COF, where a flip chip is mounted directly to a flex circuit without the use of bonding wires. Used by LCD driver ICs. COG: Chip-on-glass: Variation of TAB, where a chip is mounted directly to a piece of glass - typically an LCD. Used by LCD and OLED driver ICs.
Electric heat tracing, heat tape or surface heating, is a system used to maintain or raise the temperature of pipes and vessels using heat tracing cables. Trace heating takes the form of an electrical heating element run in physical contact along the length of a pipe.
