2. Electrical tape - Wikipedia

   en.wikipedia.org/wiki/Electrical_tape

   Electrical tape, standard black. 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.

3. Optical ground wire - Wikipedia

   en.wikipedia.org/wiki/Optical_ground_wire

   An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines. Such cable combines the functions of grounding and communications. An OPGW cable contains a tubular structure with one or more optical fibers in it, surrounded by ...

   Mechanical wire wrap tool Electrical wire wrap tool; pneumatic (air-powered) tools are also available. A "wire wrap tool" has two holes. The wire and 1 ⁄ 4 in (6.4 mm) of insulated wire are placed in a hole near the edge of the tool. The hole in the center of the tool is placed over the post.

5. Self-amalgamating tape - Wikipedia

   en.wikipedia.org/wiki/Self-amalgamating_tape

   Self-amalgamating tape. Self-amalgamating tape is a non-tacky silicone rubber tape that when stretched and wrapped around cables, electrical joints, hoses, and pipes combines or unites itself into a strong, seamless, rubbery, waterproof, and electrically insulating layer. [1][2] Unlike many other polymers and fibers, it is heat-, sunlight-, and ...

6. Friction tape - Wikipedia

   en.wikipedia.org/wiki/Friction_tape

   Friction tape is a type of woven cloth adhesive tape, historically made of cotton, impregnated with a rubber-based adhesive. Sticky on both sides, it is mainly used by electricians to insulate splices in electric wires and cables. [2] The rubber-based adhesive provides a degree of protection from liquids and corrosion, while the cloth mesh ...

7. Overhead power line - Wikipedia

   en.wikipedia.org/wiki/Overhead_power_line

   Overhead lines or overhead wires are used to transmit electrical energy to trams, trolleybuses or trains. Overhead line is designed on the principle of one or more overhead wires situated over rail tracks. Feeder stations at regular intervals along the overhead line supply power from the high-voltage grid.
