2. The high mechanical and electrical characteristics of our impregnated grade P6252 allow mounting withour any protection or end fitting .Also, in many cases, it is possible to aboid maching of bevels at the ends of the shoe.
For shoes made of plain carbon materials, it is better to mount with bronze end-fittings, which will protect the carbon by absorbing impacts and carry part of the current.A special attention is given to the soldering of the carbon into its sheath, and guarantees a perfect electrical and mechanical link.
In each case, the actual wear of the shoe will depend on material and condition of the third rail (steel, stainless-steel, )and the use, at the same time ,of castiron or steel which will damage the patina and rail.
