一、单极安全滑触线的结构是：
Structure, unipolar safety sliding contact line is:
1、导体：首要质料是铜，根据其截面积常用的有10平方、16平方、25平方。
1, Conductor: main raw material is copper, according to its cross-sectional area commonly used has 10 square, 16 square, 25 square.
2、受电器是在导管内工作的一组电刷壳架，由安顿在用电安排上的拨叉股动，使之与用电安排同步工作，将通过导轨，电刷的电能舆到电动机或其他操控元件。受电器电刷的极数有3-16极与导管中导轨极数相应。
2, by the appliance is working in the duct of a group of brush shell frame, by settling in electricity arrangement poking fork on the femoral artery, and make the electricity synchronous work, will be through the guide rail, electricity and to a motor or other control elements brush. By the electric brush pole number is 3-16 pole and the catheter guide pole number of the corresponding.
3、护套：是一根半封闭的导形管状部件，是滑触线的主体有些。内部可根据需要嵌高3-16根祼体导轨作为供电导线，各导轨间彼此绝缘，然后保证供电的安全性。本厂出产的导管每条长度为4m，可以联接成恣意需要长度，通常导管制作成直线形，也可按格外需要制成圆弧形等。
3, sheath: is a semi enclosed guide tubular parts, is the subject of some sliding contact line. According to the need of high internal embedded 3-16 root naked body guide rail as the power supply wire, each rails insulated from each other, and then ensure the safety of power supply. This factory produces catheter each length of 4m, can be connected into arbitrary need length, usually catheter made into a straight line shape, also can be made into a circular arc shape according to need the extra etc..
二、单极安全滑触线产品的特性是：
Characteristics of two, unipolar security sliding touch line of products is:
1、可靠：输电导轨导电怀能极好，散热较快，并用电流密度高、线路丢失小、电刷由具有高导电功用，高耐磨功用的金属石墨资料制成。
1, reliable transmission guide rail with excellent: conductive, fast heat dissipation, and high current density, the line loss of small, brush by a high conductive function, made of metal graphite material high wear resistance function.
2、方便：供电滑触线设备将多级母线集合于一根导管之中，组半简练。固定支架，联接夹、悬吊设备，均以通用件供应，装拆、调整、修补也非常方便。
2, convenient: power supply sliding contact line equipment combines the multi bus collection in a catheter, semi simple. The fixed bracket, the connecting clamp, suspension equipment, are in general parts supply, assembly and disassembly, adjustment, repair is very convenient.
3、安全：供电滑触线外壳系由高绝缘功用的工程塑料制成。可根据需要达以IP13、IP55级，能防护雨、雪和冰冻突击以及吊物触及。绝缘功用出色，对修补人员触及输电导管外部无任何损害。
3, security: power supply sliding contact wire shell is made of high insulation function of the engineering plastics. According to the need to reach to IP13, IP55 level, can prevent rain, snow and frozen assault and hanging touch. Excellent insulation function, repair personnel to reach transmission outside the vessel without any damage.
4、经济：供电滑触线设备计划简略，选用电流密度高，电阻率低，电压损耗低的铜排作为导电主体。可节电6%左右，实现以塑代钢，以塑代铜，无需赔偿线，设备于起重机操控室同侧，节省设备资料和经费。
4, economic power: sliding contact line equipment plan briefly, selection of high current density, low resistivity, low voltage loss of copper as a conductive body. Can save electricity by 6%, the realization of plastic steel, plastic instead of copper wire, without compensation, the device in crane control room with side, save equipment materials and funds.
