1、電流量的區(qū)別：?jiǎn)螛O滑線主要用在電流量大的場(chǎng)合，例如國家規(guī)定的200A、320A、400A、500A、630A、800A等電流量；多極滑線主要應(yīng)該在電流量小的場(chǎng)合，例如國家規(guī)定的50A、80A、120A、140A、170A、210A等場(chǎng)合。從電流量上可以看出，單極滑線可以彌補(bǔ)多極滑線的不足，通常情況下，一個(gè)車間如果滑線電流量較小的話，再上新的行車，就要考慮滑線所能承載的電流量了。而選用單極滑線，正可以解決這個(gè)問題。
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、整體結(jié)構(gòu)的區(qū)別：?jiǎn)螛O安全滑線外殼采用聚氯乙烯為原料，導(dǎo)體采用鋁合金，內(nèi)部為實(shí)體鋁合金，導(dǎo)體和滑線外殼都需要模具來制造；多極滑線外部采用聚氯乙烯為原料，導(dǎo)體采用銅條。 多極滑線內(nèi)部為中空。從這可看出，在運(yùn)輸多極滑線途中，對(duì)包裝要有要求。
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、安裝方式的區(qū)別：?jiǎn)螛O滑線可以采用三線四線制安裝方式，或者三線三線制，目前國家已經(jīng)出臺(tái)只能按照三相三線制安裝。多極滑線只采用單線制安裝，單極滑線的角鋼支架和多極滑線角鋼支架相差在5cm左右，安裝基本相同，由此可以看出多極滑線安裝空間要小于單極滑線。
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、使用維護(hù)的區(qū)別：?jiǎn)螛O滑線使用三相四線制，如果滑線出現(xiàn)故障，可以很容易的檢修，并找到出問題的點(diǎn)；而多極滑線，由于各級(jí)別的銅條都在一條管子內(nèi)不，對(duì)檢修造成一定難度；多極滑線更換和采購的成本要大于單極滑線。
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.
