Caledonian thin wall rolling stock cables conform to EN 50306 (The corresponding French railway standard is NF

F 63808) are ozone resistant, acid and alkali resistant, mineral oil, fuel oil and UV light resistant. Anti-termite

cables and anti-rodent cables can also be offered upon customer request.

Application:

FIREROL thin wall rolling stock cables combine the advantages of small size, lightweight, high oil resistance,

halogen free, high mechanical properties. They are recommended for installation in railway vehicles (locomotives,

trains, trolleybuses...).

A 120 °C conductor temperature is allowed for a 20000 hours cumulative working time.

The external sheath is mineral oil and fuel oil resistant, ozone and UV resistant.

Conductors:

Flexible stranded tinned copper class 5 according to IEC 60228 with optional separator tape. Conductor

temperature +90/105 °C or +105/125 °C

Insulation:

Crosslinked halogen free polyethylene or polymer

Sheathing:

Cables sheathed with special S1 and S2 compounds (described in EN 50306-1) or EN 50264 sheathing

compounds (EM 101. EM 102. EM 103 and EM 104)
