2. Heat-shrink tubing - Wikipedia

   en.wikipedia.org/wiki/Heat-shrink_tubing

   Animation of heat-shrink tubing, before and after shrinking. Heat-shrink tubing (or, commonly, heat shrink or heatshrink) is a shrinkable plastic tube used to insulate wires, providing abrasion resistance and environmental protection for stranded and solid wire conductors, connections, joints and terminals in electrical wiring.

3. Electrical conduit - Wikipedia

   en.wikipedia.org/wiki/Electrical_conduit

   The conduit has an open face with removable cover, secured to the surface, and wire is placed inside. Plastic raceway is often used for telecommunication wiring, such as network cables in an older structure, where it is not practical to drill through concrete block. Advantages. Allows adding new wiring to an existing building without removing ...

4. Insulator (electricity) - Wikipedia

   en.wikipedia.org/wiki/Insulator_(electricity)

   A flexible coating of an insulator is often applied to electric wire and cable; this assembly is called insulated wire. Wires sometimes don't use an insulating coating, just air, when a solid (e.g. plastic) coating may be impractical. Wires that touch each other produce cross connections, short circuits, and fire hazards.

5. Thermoplastic-sheathed cable - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic-sheathed_cable

   The earth conductor is always stranded (unlike North American usage), with the exception of 1 mm 2 cables, and covered with green-yellow striped plastic insulation. In older cables the plastic insulation of the earth conductor is green. [6] Prior to the introduction of TPS cable, tough rubber sheathed (TRS) cable was used.

6. Electrical tape - Wikipedia

   en.wikipedia.org/wiki/Electrical_tape

   The first commercially available version of the tape was sold for use as a wire-harness wrapping. This original electrical tape wasn't black. [5] Tapes formulated for high-temperature were yellow, and later versions were white. Electrically insulating tapes are essential for enhancing functionality and reliability in a wide range of applications.

9. Electrical wiring - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring

   The earliest standardized method of wiring in buildings, in common use in North America from about 1880 to the 1930s, was knob and tube (K&T) wiring: single conductors were run through cavities between the structural members in walls and ceilings, with ceramic tubes forming protective channels through joists and ceramic knobs attached to the ...
