On the insulated cable used for electrical wiring design of fire-fighting equipment - fire equipment, electrical wiring and fire protection materials
?? Fire fighting equipment when the fire broke the normal operation of the evacuation, control fire spread and reduce fire losses have an important role. Therefore, the electrical distribution line fire-fighting equipment shall meet the reliability of distribution systems, fire resistance, safety, effectiveness, scientific requirements to ensure that fire fighting equipment fire power will not be interrupted to protect the personal safety, to ensure continuous power supply time, and strive to ensure the quality of power supply system wiring is simple, investment, low operating costs.
Electrical Wiring with Aluminium and Copper
Copper wiring is the mostly used wiring in electrical, the main reason being its high electrical conductivity. Its high conductivity allows the electricity to pass through it without being much heated up. Because of high cost of copper wire, aluminum wires are being used in its place. The low cost of aluminium wire make them the popular in electrical wiring.
Two Commonly Used Metals in Electrical Wiring
Copper is one of the most commonly used metals for electrical wiring. The obvious reason being its high electrical conductivity. The conductivity of copper allows the electricity to pass through it without being much heated up. Owing to its high cost, aluminium wires started being used in place of copper wires. Aluminium wires had been used widely in the North American residential wiring from 1960s to 1970s.
