电缆桥架常见规格有： Current specifications of channel-style cable tray(fully closed-end): 250250 150250 150300 100250 150200 梯级式电缆桥架常见规格有： 100200 150200 100600 150600 100800 150800 100500 150500 100300 150300 100400 150400电缆桥架规格表示方法: XQJ-形式类别规格 XQJ表示汇线桥架系列 形式表示结构形式（用中文第一个汉语拼音的大写字母 T为梯级式、P为托盘式 C为槽式、ZH为组合式） 类别表示类别种类序号（用阿拉伯数字加英语字母表示） 规格表示规格或规格序号（用阿拉伯数字表示） 电缆桥架尺寸选择与计算: 电缆桥架的载荷G总的计算 G总=n1q1+n2+q2+n3q3+. 式中：q1、q2、q3.为各电缆每单位长的重量（kg/m） n1、n2、n3.为相应的电缆根数 G应小于电缆桥架的允许载荷（参照载荷曲线图表） 当电缆桥架在室外或带护罩时，还应计入水载和风载等因素。 电缆桥架宽d度的计算：1、电力电缆 b=n1(d1+k1)+n2(d2+k2)+n3(d3+k3)+. 式中：d1、d2、d3.为各电缆直径；n1、n2、n3.为相应电缆直径的根数； k1、k2、k3.为电缆间距（K值最小不应小于d/4） 控制电缆桥架的宽度b的计算：（一般电缆桥架的填充率取40%左右） 电缆的总载面积：S0=n1(d1/2)2+n2(d2/2)2+. 需要的托架横载面积：S=S0/40% SS/hS0/40%h 式中：h为电缆桥架净高。 150*75表示桥架宽度150mm高度75mm 规格 在空气中载流量（A） YJV-0.6/1KV 3*4+1*2.5 30
