横梁8的截面形状、滑动方法以及将支撑件420和锚固夹110附接至支撑杆100的横梁的方法同上。应该注意的是,在所有描述的实施例中,悬臂的几何形状总是呈三角形矩形三角形类型,即,悬臂是由支撑供电电缆支撑件的水平横梁以及至少一个倾斜支撑杆形成。从以上描述中可以看出,根据本发明的悬臂使得克服上文所述现有技术中的缺点成为可能。事实上包括弯曲边缘的形状接合形成下切,并也能在不将支撑件支撑在悬臂上的情况下使支撑件滑动。在一个实施例中,支撑杆100也是由绝缘材料制成。

在例如25KV的高速铁路线上,电绝缘设置在支撑桥塔16与悬臂400之间而不是设置在电缆与横梁8之间。具体地,第一绝缘体430置于桥塔16与支撑杆100之间,而第二绝缘体440置于桥塔与横梁8之间。横梁8由位于电缆支撑件620附近、一侧附接至柱160且另一侧附接至横梁8的至少一个支撑杆100支撑。所述支撑电缆622是由绝缘材料制成。该几何特征的具体优势在于,仅通过沿着横梁移动相关支撑件就能调节轨道线的位置和接触线的位置。此外,由于与悬臂的相应附接部分的形状接合,电缆支撑件总是能相对于横梁正确地有角定向;换句话说,装配工完全不必担心发生像具有圆形截面的横梁的现有技术方案中中所发生的支撑件的角定向问题。
此外,在柱160与横梁8之间插入有另一个绝缘体630。在图12-15所示的关于电车线的实施例中,悬臂600与上述悬臂不同之处在于,至少一个电缆支撑件620是沿着横梁8放置的,包括附接至横梁8低轮廓侧28的基部40以及附接至所述基部40且支撑横向支撑电缆622的夹621,所述横向支撑电缆622支撑供电电缆3。事实上,电缆支撑件的布置总是既正确又快速,因为只要求在正确布置前松开螺栓或螺钉,使支撑件沿着相应的垫板滑动。相反地,横梁同支撑杆一样保持在相同位置上。将绝缘体放置在桥塔附近且与横梁和支撑杆成一条直线,而不是放置在电缆支撑件上和定位臂上,这可避免由于绝缘体的径向负载导致在横梁上产生危险的动量。
这使得悬臂的装配和支撑件的调节变得更快速安全。优选地,悬臂4由铝或铝合金制成。 It ought to be noted that in all described embodiments the geometry of the cantilever is always of the triangular rectangular triangular type, ie the cantilever is formed by a horizontal beam supporting the provision cable help and a minimum of one inclined assist bar. As could be seen from the above description, the cantilever in keeping with the invention makes it potential to beat the disadvantages of the prior artwork described above. Even with a minimal movement fee of .5 GPM it is possible to have a move associated downside however it's too much simpler to solve. In items that can not management their outlet circulate, electric cable you will need to "throttle" the stream price yourself on the outlet. Strong and efficient legal guidelines on this area are important because technical measures can do no more than serve as obstacles to unauthorized use and such measures will all the time be topic to defeat. Maintained to the very best requirements, our cable wire pullers are ready to your subsequent challenge.
