在人口密度较小的作业区可以选用任意一种阻燃电缆。(2)阻燃电缆分为A、B、C3类,其中A类阻燃电缆性能较B、C类更优,价格也最贵。设计人员提供订货清册时应标明阻燃电缆的类别。(3)从外观上无法区分阻燃电缆的A、B、C类别,只有靠制造厂家进行供货保证,因此在设计选用时应慎重选择电缆制造厂家。
IN/OUT类型:将指定位置的参数传到子程序,从子程序来的结果值被返回到同样的地址。常数和地址值不允许作为输出参数。TEMP类型:局部存储器只能用作子程序内部的暂时存储器,不能用来传递参数。局部变量表的数据类型可以是能流、布尔(位)、字节、字、双字、整数、双整数和实数型。能流是指仅允许对位输入操作的布尔能流(布尔型),梯形图表达形式为用触点(位输入)将电源母线和指令盒连接起来。在局部变量表输入变量名称、变量类型、数据类型等参数以后,双击指令树中的子程序(或选择点击方框快捷按钮,在弹出的菜单中选择子程序项),在梯形图显示区显示出带参数的子程序调用指令盒。
3. 绝缘厚度:3.3线芯绝缘厚度为0.5,绝缘后外径为3.5毫米。0.85线芯绝缘厚度为0.7绝缘后外径为2.5毫米。4. 成缆时把四根线芯排列为红,绿,蓝,白,排流线,排流线要和线芯一起绞合,千万不要纵放,成缆时不要加填充物,缆芯外用铝箔绕包,而后再绕包一层聚酯膜,在外有一层铜丝编织屏蔽(屏蔽铜丝不镀锡)。
对于星绞式电缆,其排列顺序为:星绞组数×每组心线数×导线直径(mm) 50×4×0.5—100对电缆对于对绞式电缆,其排列顺序为:心线对数×每对心线数×导线直径(mm) 100×2×0.5—100对电缆。
