井下低压电缆截面选择探讨

Probe into Selection of Cross Section of Underground low Voltage Power Cables

井下低压供电质量与电缆截面选择有着密切的连系,电缆截面大不经济;电缆截面小则电压损失大,负荷不能正常工作,甚至不能启动或磁力启动器不能吸持。合理选择井下低压电缆截面,可为提高供电质量提供客观依据。

The quality of Underground low voltage power supply is in contact with the choice of cable cross section. Large cross section caused the high cost. But the small cross section caused the large voltage loss and the load is not working properly, which also caused magnetic starter can not work. It can be to improve the quality of supply that the reasonable selection of underground low voltage cable cross section.
