<br/>
</span>按公式算线长<span lang="EN-US">,</span>以我的经验是一定不准的<span lang="EN-US"> <br/>
<br/>
</span>但是也没有一定准确方法<span lang="EN-US"> <br/>
<br/>
</span>在施工的过程里还有不可预测的变动呢<span lang="EN-US"> <br/>
<br/>
</span>我们国家对八芯双绞线<span lang="EN-US">(</span>包括五类<span lang="EN-US">,</span>超五类<span lang="EN-US">,</span>六类<span lang="EN-US">)</span>最长布线距离规定在一百米以内<span lang="EN-US"> <br/>
<br/>
</span>设计院设计图纸的时候一定也会考虑到<span lang="EN-US"> <br/>
<br/>
</span>那么一般情况下最短的线应该在十米左右<span lang="EN-US">,</span>最长的线在九十米左右<span lang="EN-US">(</span>留十米的余量<span lang="EN-US">) <br/>
<br/>
</span>平均一下<span lang="EN-US">,</span>每根线在五十米左右<span lang="EN-US"> <br/>
<br/>
</span>如果穿越楼层的话<span lang="EN-US">,</span>每根再加个楼层高度就可以了<span lang="EN-US"> <br/>
<br/>
</span>误差不会太大<span lang="EN-US"> <br/>
<br/>
</span><b style="mso-bidi-font-weight: normal">最关键还是要看现场情况<span lang="EN-US">,</span>以及要熟练看懂图纸<span lang="EN-US">,</span>这个是要时间和磨练的</b></pre> |
