【每周一課】H型單極安全滑觸線對比管式多極安全滑觸線

就現(xiàn)在工業(yè)設備供電安全滑觸線來說，H型單極滑觸線和管式多極安全滑觸線應用范圍比例較高。

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型單極安全滑觸線采用鋁合金和銅作為導體，內鑲不銹鋼帶，增加耐磨性，導線采用平行排列方式。載流量由200A-2000A不等?？梢詽M足不同設備不同環(huán)境需求。其散熱性、安全性、導電性都是移動設備的首選。正規(guī)廠家生產的滑觸線如濟南德瑪電氣，使用壽命較長，正常維護保養(yǎng)前提下，可達10余年，是最受客戶青睞的一類產品。

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.

管式多極安全滑觸線采用特殊工藝聚氯乙烯外殼加銅片構成，內部結構中空，集電器通過碳刷與導管四周的銅導體接觸摩擦取電。集電器內部通過彈簧控制碳刷伸縮。管式滑觸線集電器結構特殊，建議選擇正規(guī)廠家產品，彈簧質量好，能夠自由控制與導體接觸面積，使用壽命長，故障率低。管式多極安全滑觸線應用于200A以下設備，使用范圍較小。

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.
