1.PC20 管:
照明回路WL1 : ( 4+0.05-1.5-0.8 ) +1.88+0.7+ ( 4+0.05-1.3 ) +1.43+3.6 × 4+3.1 × 7+(2.4+4+0.05+0.3-3.5-0.05)+1.95+(4+0.05-1.3)=52.51(m)
插座回路:[(0.5+0.05+2.93+(0.05+0.3)×2+3.45+(0.05+0.3)]=7.98(m)
PC20 管小计:52.51+7.98=60.49(m)
2.PC40 管:
WP1 回路:(1.5+0.05)+12.6+(0.5+0.05)=14.70(m)
插座箱到动力插座:(0.5+0.05+4.45+0.05+1.4)=6.45(m)
PC40 管小计:14.70+6.45=21.15(m)
3.管内穿2.5mm2 线:
三线:(0.6+0.8)×3+[(4+0.05-1.5-0.8)+1.88+1.43+3.6×2+3.1×4+((2.4+4+0.05+0.3-3.5-0.05))]
×3=92.38(m)
四线:(3.6×2+3.1×3)×4=66(m)
五线:[0.7+(4+0.05-1.3)+1.95+(4+0.05-1.3)]×5=40.75(m)
管内穿2.5mm2 线合计:92.38+66+40.75=199.13(m)
4.管内穿16mm2 线:
(0.6+0.8)×5+[(1.5+0.05)+12.6+(0.5+0.05)]×5+(0.3+0.3)×5=83.50(m)
(0.3+0.3)×3×2+[(0.5+0.05+2.93+(0.05+0.3)×2+3.45+(0.05+0.3)]×3+(0.5+0.05+4.45+0.05+1.4)×3=3.6+7.98×3+6.45×3=46.89(m)
管内穿16mm2 线合计:83.50+46.89=130.39(m)
