【每周一课】H型单极安全滑触线对比管式多极安全滑触线

就现在工业设备供电安全滑触线来说，H型单极滑触线和管式多极安全滑触线应用范围比例较高。

As far as the safety sliding contact wire for power supply of industrial equipment is concerned, H-type unipolar sliding contact wire and tubular multipolar sliding contact wire have a high proportion of applications.

H型单极安全滑触线采用铝合金和铜作为导体，内镶不锈钢带，增加耐磨性，导线采用平行排列方式。载流量由200A-2000A不等。可以满足不同设备不同环境需求。其散热性、安全性、导电性都是移动设备的首选。正规厂家生产的滑触线如济南德玛电气，使用寿命较长，正常维护保养前提下，可达10余年，是最受客户青睐的一类产品。

H-type unipolar safety slip contact wire uses aluminium alloy and copper as conductors, inlaid with stainless steel strips, to increase wear resistance, and conductors are arranged in parallel. The carrying capacity varies from 200A to 2000A. It can meet the different environmental needs of different equipment. Its heat dissipation, safety and conductivity are the first choice for mobile devices. Sliding contact wires produced by regular manufacturers, such as Jinan Dema Electric, have a long service life. Under the premise of normal maintenance, they can reach more than 10 years. They are the most popular products among customers.

管式多极安全滑触线采用特殊工艺聚氯乙烯外壳加铜片构成，内部结构中空，集电器通过碳刷与导管四周的铜导体接触摩擦取电。集电器内部通过弹簧控制碳刷伸缩。管式滑触线集电器结构特殊，建议选择正规厂家产品，弹簧质量好，能够自由控制与导体接触面积，使用寿命长，故障率低。管式多极安全滑触线应用于200A以下设备，使用范围较小。

The tubular multipolar safety slip contact wire is composed of a special process PVC shell and copper sheet. The inner structure is hollow. The collector rubs against the copper conductor around the tube to collect electricity. The inner part of the collector controls the expansion and contraction of the carbon brush through a spring. Because of the special structure of the tubular slip-contact collector, it is suggested to choose the products from the regular manufacturers. The spring has good quality, can freely control the contact area with the conductor, has long service life and low failure rate. The tubular multipolar safety sliding contact wire is applied to equipment below 200A, and its application range is small.
