什么是交叉电缆，当你会使用它？
交叉电缆在学员小组(高度竞争的学员的一个重要特征)之间提供“气隙(Air Gap)”安全性。
The crossover cable provided "air gap" security between student teams, an important feature with highly competitive students.
伴热电缆的交叉：在易燃易爆场合必须采用配套的防爆直线型接线盒，一般场合也可以采用绞接或焊接。
Heating cable cross: must be used in explosive situations linear supporting proof junction box, the general situation can also be used splice or welding.
电缆应按图纸要求规定的路径敷设，敷设时尽量减少交叉，电缆要排列整齐。
The cable should be laid according to the route specified in drawings. And while laying, there should be as little cross as possible, and the cables should be arranged orderly.
高压电缆的金属护套交叉互联导致行波在多个波阻抗不连续点产生了复杂的折反射行为，这对高压电缆线路的行波故障测距产生很大的影响。
The reflection and refraction of traveling wave are quite complicated at the sheath-crossing point of high voltage power cable, due to its remarkably noncontinuous surge impedance.
电缆敷设时合理安排电缆敷设顺序，尽量减少电缆交叉。
Make sure of a reasonable arrangement for the cable laying orders, and furthest minimize the case of the cable frogging.
用于直埋、工井或隧道内敷设的两段电缆连接，电缆金属护套可直接连接，也可交叉连接。
For connection of two sections cable in direct burial, working well or tunnel, the cable metal bushing can be connected directly, and also can be connected across.
在水平管道安装时，可敷设在管道下部45度处，伴热电缆安装时允许多次交叉重叠，但尽可能减少扭曲。
When installed in horizontal pipes can be laid at 45 degrees lower in the pipeline, heating cable installation allows multiple overlapping, but to minimize distortions.
