Elstolparna - hållbarhet (Elektrifiering/elektrisk drift)

av Jan Frelin, Tuesday, September 16, 2008, 22:20 (5931 dagar sedan) @ Richard Loe

Generellt så räknar man med att en galvaniserad stolpe i stål/järn varar ungefär 80 år, och en stolpe i trä (med behandling typ kreosot) ungefär 40 år. Så det börjar nog bli dags för stolpbyte utmed en del av våra järnvägar på samma sätt som Svenska Kraftnät nu börjar riva och bygga om de äldsta delarna av stamnätet (som är nu lite över 70 år).

Det väcker omedelbart den viktiga frågan om bevarande av aäldre kraftledningsstolpar! :-P Finn nån utanför Örsundsbro, t.ex.
