求三相五线电缆的计算

ac米兰

请问高手，在设计中计算设备的功率要用多大的电缆线，是怎样计算的。

正规的专业设计都是根据国家相关的设计规范要求及技术规范要求来计算的。不是一句两句话说的清楚的。
在选择电缆的截面时，要考虑的因素很多，设备功率、功率因数、使用系数、环境温度、冷却条件、电缆长度、敷设条件等等。
如果是我们自己计算一些临时设备用电缆时，可参考一下“电气口诀”ShowPost.asp?ThreadID=5222

The up side with this talent
spec wow power leveling is that the Shaman will be able to gain on their damage and their critical strike chances.
Once a Shaman of Elemental spec hits their seventh tier, they gain Elemental Mastery, which is an extremely usable wow power leveling spell that can be cast every three minutes. This spell will guarantee a mana- will
greatly aion power level increase the damage that a Shaman can do, and the magical offense as well. So, for
both PvP aion powerleveling and PvE, this is a great talent tree to go with.
The Enhancement talent tree enhances the Shaman's abilities to provide special timed enchants on their aion powerleveling weapons and to expand on their melee abilities. This talent spec is appealing to lower
level Shamans since it offers a mana increase, reduced cast time, and gives them the ability to u  cheap aion power leveling two-handed weapons. Further up the Enhancement talent tree, the Shaman can begin to do a huge amount of melee damage wow power leveling and can even surpass some Warriors and Rogues. But, they will start to lack
the buy wow gold ability to reduce threats, so this can make it hard to ward off aggro.
