辨别滑触线质量的四大要点：
Identify the four points of sliding contact line quality:
1、导体铝合金材料质量和来源。这一因素，也是决定滑触线价格的主要因素，铝合金导体材料比较好，价格也就高，相反亦然。
1, aluminum alloy conductor material quality and sources. This factor, is to determine the main factors of the sliding contact line price, aluminum alloy conductor material is better, the price is high, vice versa.
2、PVC外壳的厚度。通常来说，滑触线外壳起到保护滑触线导体，起到绝缘作用，同时起到防晒、防潮、防雨雪、防灰尘的作用。
2, the thickness of the PVC casing. Generally speaking, the sliding contact line enclosure protection sliding contact line conductor, the insulation effect, at the same time prevent bask in, moistureproof, prevent rain and snow, dust prevention role.
滑触线外壳的厚度也是衡量滑触线质量的一个标准，如果滑触线外壳比较薄，可能会发生人为不小心损坏滑触线，同时，安全性能也会大大降低。
Sliding contact line is the thickness of the shell is a measure of the sliding contact line quality, if the sliding contact line of the shell is thin, people could occur accidentally damaged sliding contact line, at the same time, the safety performance will be greatly reduced.
3、整体外观设计。这一项看似起不了多大作用，其实也是占有一定份额的，滑触线的整体外观设计符合大多数工程环境，而且外观设计利于保护滑触线，更从美学角度上增加了亮点。这在滑触线市场上会为产品提高竞争力。
3, the overall design. This one seems to have little effect, but also occupy a certain share, sliding contact line conform to the majority of the engineering environment, the overall appearance design and appearance design to protect sliding contact line, the more increase the highlights from the aesthetic Angle. The market for the product on the sliding contact line more competitive.
4、导体截面积、导体厚度。很明显导体截面积越大，其散热性就越好；导体厚度越厚，其导电能力越强。购买滑触线的时候，一定要观察滑触线导体截面积，同时也要观察导体的厚度，不排除，有些厂家，将其电流小的滑线冒充成电流大的滑线。
4, conductor cross-sectional area, the thickness of the conductor. Obviously the bigger the conductor cross-sectional area, the heat dissipation is better; Conductor thickness is thicker, the better its conductivity. Buy sliding contact line, must observe the sliding contact line conductor cross-sectional area, as well as to observe the thickness of the conductor, do not rule out that some manufacturers, the current small slip line masquerading as current big slide wire.
