2. Silicone rubber - Wikipedia

   en.wikipedia.org/wiki/Silicone_rubber

   Silicone rubber is used as an electrical insulator in power cables and cable joints. [18] [21] Silicone-insulated cables are advantageous in that they can withstand temperatures from -90°C to 200°C, and are highly flexible. These properties make them suitable for maintaining circuit integrity in the event of a fire.

3. 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.

4. Thermoplastic-sheathed cable - Wikipedia

   Orange: 10 AWG wire (5.26 mm 2) for 30-amp circuits Black: 6 or 8 AWG wire (13.3 mm 2 or 8.37 mm 2) for 60- and 45-amp circuits, respectively Grey: usage for underground installations, designated as "underground feeder" (UF) cables [4] The outer jacket is labeled with letters that show how many insulated wires are concealed within the sheath.

5. Wire wrap - Wikipedia

   en.wikipedia.org/wiki/Wire_wrap

   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. The tool is rapidly twisted. The result is that 1.5 to 2 turns of insulated wire are wrapped around the post, and above that, 7 to 9 turns of bare wire are wrapped around the post.

7. Insulator (electricity) - Wikipedia

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

   Film-insulated magnet wire permits a manufacturer to obtain the maximum number of turns within the available space. Windings that use thicker conductors are often wrapped with supplemental fiberglass insulating tape. Windings may also be impregnated with insulating varnishes to prevent electrical corona and reduce magnetically induced wire ...
