多极安全滑线与单极安全滑线有那些区别

1、电流量的区别：单极滑线主要用在电流量大的场合，例如国家规定的200A、320A、400A、500A、630A、800A等电流量；多极滑线主要应该在电流量小的场合，例如国家规定的50A、80A、120A、140A、170A、210A等场合。从电流量上可以看出，单极滑线可以弥补多极滑线的不足，通常情况下，一个车间如果滑线电流量较小的话，再上新的行车，就要考虑滑线所能承载的电流量了。而选用单极滑线，正可以解决这个问题。
The difference between the 1, the amount of the current: mainly used in the current situation of large amount of unipolar slip line, such as the provisions of the state of 200A, 320A, 400A, 500A, 630A, 800A and other current; multipole slip line should be a small amount of current situations, such as the provisions of the state of 50A, 80A, 120A, 140A, 170A, 210A etc.. From the current amount can be seen, unipolar slip line can make up for a lack of multipole slip line, under normal circumstances, a workshop if slip line current is smaller then, to a new road, it must consider the current slide wire can load weight. The unipolar slide wire, it can solve this problem.
2、整体结构的区别：单极安全滑线外壳采用聚氯乙烯为原料，导体采用铝合金，内部为实体铝合金，导体和滑线外壳都需要模具来制造；多极滑线外部采用聚氯乙烯为原料，导体采用铜条。 多极滑线内部为中空。从这可看出，在运输多极滑线途中，对包装要有要求。
The difference between the 2, the overall structure: unipolar safe slide wire shell is made of polyvinyl chloride as raw materials, the use of aluminum alloy inner conductor, solid aluminum alloy, conductor and slide wire casing all require special mold to manufacture; multipole slide wire external use of polyvinyl chloride as raw materials, using copper conductor. Multipole slip line hollow. From this can be seen in the transportation, multi slide way, a request for packing to.
3、安装方式的区别：单极滑线可以采用三线四线制安装方式，或者三线三线制，目前国家已经出台只能按照三相三线制安装。多极滑线只采用单线制安装，单极滑线的角钢支架和多极滑线角钢支架相差在5cm左右，安装基本相同，由此可以看出多极滑线安装空间要小于单极滑线。
The difference between the 3, installation methods: single slip line can use three line four line installation, or three line three line, the country has issued only in accordance with the three-phase three wire system installation. Multipole slip line using only single line installation, unipolar slip line angle bracket and multipole slip angle bracket is about 5cm, the installation is basically the same, we can see that the multipole slide wire mounting space than the unipolar slip line.
4、使用维护的区别：单极滑线使用三相四线制，如果滑线出现故障，可以很容易的检修，并找到出问题的点；而多极滑线，由于各级别的铜条都在一条管子内不，对检修造成一定难度；多极滑线更换和采购的成本要大于单极滑线。
4, use and maintenance of difference: unipolar slip line four line system using phase, if the slip line failure, can repair easily, and find out the problem points; and multipolar slide wire, the copper strip of each level are in a tube not, cause certain difficulty to the maintenance cost of slip line replacement; and procurement of multipole than unipolar slip line.
