<p>The invention relates to a splice bar (6), in particular for a buried rail, including a material forming a matrix, and at least one web of fibers (13, 14) extending longitudinally, the shrinkage coefficient of the fiber being lower than the shrinkage coefficient of the thus-formed splice bar and lower than 0.04%/ºK. Such a splice bar is particularly suitable for use in regions having a wide temperature range, in order to, in particular, limit the risk of stray current leakage.</p> |
