TBM gantry & advancing tunnel reel
Galvanised steel wire armour (SWA) over extruded LSZH inner bedding allows direct burial and culvert routing.
Product
Halogen-free 300/500 V armoured process instrumentation cable built to BS EN 50288-7 with Class 2 copper conductors, +90 °C XLPE (2X) insulation, collective or PiMF Al/PET screen, LSZH inner bedding, galvanised steel wire armour (SWA) and LSZH outer sheath.
Typical values for this cable type, based on BS EN 50288-7 / EN 10257-1 / IEC 60754 — confirmed in the datasheet and quotation for your order.
Application fit
Engineered for direct burial, exposed process pipe racks, LNG terminals, utility tunnels and hazardous areas requiring both SWA mechanical protection and zero-halogen LSZH fire performance.
Galvanised steel wire armour (SWA) over extruded LSZH inner bedding allows direct burial and culvert routing.
UV-stabilised LSZH outer sheath and SWA armour withstand harsh open-air petrochemical environments.
Routes directly from outdoor trenches into indoor halogen-free DCS marshalling rooms without transition boxes.
SWA armoured construction is exclusively for fixed installations and direct burial.
