FAQ

Questions engineers ask first

How do Network Rail Type E1 / E2 cables differ from Type B1 / B2 and Type C1 / C2?
In NR/PS/SIG/00005, Type B1/B2 are unscreened and unarmoured; Type C1/C2 are steel-wire-armoured (SWA) without a copper screen; and Type E1/E2 combine BOTH a collective copper EMC screen and galvanised steel wire armour (SWA) for 25 kV AC OLE electrified routes.
Why are the copper screen and the steel wire armour separated by an inner bedding sheath in Type E1 / E2?
The elastomeric bedding sheath isolates the collective tinned copper screen from the galvanised steel wire armour (SWA) so the copper screen can be terminated cleanly to the clean signalling earth bar while the SWA is clamped in an outdoor brass cable gland.
Can NR Type E1 / E2 be installed directly in the ground without concrete troughing?
Yes. Because Type E1 / E2 incorporates full round galvanised steel wire armour (BS EN 10257-1) beneath a heavy-duty BS 7655 EM2 PCP outer sheath, it is approved for direct burial, under-track crossings (UTX), and elevated post routes.
What is the difference between Type E1 and Type E2?
Type E1 covers screened, armoured circular multicore signalling cables (typically 4 to 40 cores of 1.5 mm² or 2.5 mm²), whereas Type E2 covers screened, armoured 2-core tail and feeder cables (2.5 mm² up to 35 mm²).
