The thickness of the wire (cross-sectional area of the wire) corresponds to the load capacity, that is, the allowable normal working current. Purely theoretically, the thicker the wire diameter, the smaller the line loss, and the smaller the wire diameter, the greater the line loss. This is not wrong. But you can't blindly increase the diameter in order to save electricity once every 10 years. This is neither economical nor necessary. The selection should be based on the allowable nominal current of the wire to match the maximum working current of the line. As for someone who mentioned that the working current of the short-circuit fault increases sharply, this can not be solved by thickening the wire diameter, but by selecting the appropriate circuit breaker in the distribution box to ensure the safety of electricity use.
Wajers irqaq se jikkunsmaw aktar enerġija. Hemm żewġ raġunijiet. L-ewwel, meta l-wajers huma rqaq, ir-reżistenza hija kbira, u s-sħana ġġenerata taħt l-istess kurrent hija kbira, li tikkonsma aktar enerġija. It-tieni, meta r-reżistenza hija kbira, il-waqgħa tal-vultaġġ hija kbira, u l-vultaġġ tat-tagħbija finali huwa baxx. Għal ħafna tagħbijiet, bħal muturi, il-vultaġġ baxx se jwassal għal effiċjenza baxxa, il-kurrent se jiżdied minflok, u l-konsum tal-enerġija se jiżdied b'mod sinifikanti.
Iktar ma jkun żgħir il-wajer, akbar tkun ir-reżistenza, li se tikkonsma aktar enerġija relattivament, iżda l-parti tat-telf multi-hija kważi negliġibbli!
It's not that thicker wires save power!
Jiddependi fuq is-sitwazzjoni speċifika. Meta ċ-ċirkwit ikun imqabbad, jinstab li l-wajer jissaħħan, u l-enerġija elettrika tiġi kkunsmata f'parti mill-wajer. Naturalment, il-wajer huwa ċċarġjat fin. Innota li f'dan il-każ, il-wajers eħxen għandhom jiġu sostitwiti fil-ħin biex jipprevjenu inċidenti!
