Cable select matters needing attention
1, according to the selection of laying mode cable protective serial number (whether with armour )
2, under the conditions of use, regional and economic choice Cu or Al conductor
3, according to the load selection specifications and core number: lighting load selected 4 core, office buildings and important building 4+1 is less than 25mm2 core, 5 core.
4, with the match line voltage grade.
5, according to the experience of 1kV and below the cable current is normally the power 2 times, pure resistive load current is 1.5 times its power.
6, when the cable length greater than 400 meters, to consider when selecting cables voltage drop.
7, select cable specifications mainly considers the current size, laying mode.
8, the cable selection should also be considered when the maximum load starting current, the future development of projects, sectional allowance.
