天皋单机组合式滑触线产品介绍：
tiangao Single machine combined sliding contact line product introduction:
HXPnR-H系列排式单极安全滑线导轨，其导电主体为断面呈“H”型的铝型材，故又称“H”型节能滑线装置，节能是相对于以角钢为主体的滑触线，电能在输电过程中的损耗大大地被减小。滑触线
HXPnR - H series type single safety sliding guide rail, the conductive body to section "H" type of aluminum, so it is also called "H" type energy saving slide wire device, saving energy is relative to the sliding contact line with Angle steel as the main body, the electric energy in the process of transmission loss is significantly reduced.
铝材的电阻率远远低于钢材，且比重又小，将铝材轧制成“H”型，是在保证一定的导电截面积的基础上以能提高其整体刚性和强度，但是铝材的表面硬度低且不耐磨的特殊物质，大大延长使用寿命。
The resistivity of aluminum was far below the steel, and the proportion of small, aluminum rolling into "H" type, is on the basis of the guarantee of conductive cross-sectional area to improve the overall rigidity and strength, but the surface of the aluminum low hardness and low wear resistance of special material, greatly extend the service life.
滑线导轨的表面，除下部开口与集电器接触外，其余部分用PVC塑料作整体保护，成为密封式。
The surface of sliding guide rail, in addition to the bottom openings in contact with the collector, with the rest of the PVC plastic for the overall protection, be sealed.
安装后的滑线无导电的外露部分，给安装和维修带来方便，同时整体外壳保护，使滑触线不积灰和防雨、露、冰、雪侵袭之功能，从而保证机械安全可靠的运行。
After installation of the exposed portion of slide wire without conductive, bring convenience to installation and maintenance, the overall enclosure protection at the same time, make the sliding contact line is not dust and rain and dew, snow, ice, the function of invasion, thus ensuring safe and reliable mechanical operation.
