Domestic and Industrial Wiring MCQ [Free PDF] - Objective - Testbook Although available in the larger sizes, solid conductors are rarely used with wire sizes greater than 1mm2 CSA, since the small increase in manufacturing cost of stranded conductors is far outweighed by the relative ease of working with them, especially at the points of termination. However, if expanded polystyrene is in intimate contact with PVC sheathed cables, over time a chemical reaction can draw out the sheath plasticiser to form a sticky layer on the outside of the cable. Customization can be easily done in this wiring system e.g. It is not lasting, reliable and sustainable wiring system. 2.What are the following cable types used for and how are they made?

PVC conduits offer a highly resistant against corrosion. Mineral-insulated copper-clad cable - Wikipedia cables and fibre optic cable fail during the ammability test (CA T A) on bunch of cables which . Thermoset or crosslinked PVC has improved temperature resistance, is tougher and has better dielectric strength, and the table name can apply a thinner coating or insulating layer to make the overall cable size smaller. It can be cleaned away with methylated spirits, wearing gloves and paying proper attention to hygiene, and after use the cleaning materials must be properly disposed of. Material of inner sheath should be PVC Type ST2 as per IS:5831-1984. Therefore, some phosphorus-containing and sulfur-containing plasticizers should be excluded.
