GRC Cable Trough

GRC Cable Trough

Network Rail PADS approved cable troughs and elevated cable troughing from BCM are manufactured from glassfibre reinforced concrete (GRC) and are installed at trackside ground level, over bridges and through rail tunnels.

The new design cable trough and elevated channel overcomes E&P and S&T security and safety issues including finger trapping, lid “popping” and cable troughs dropping between support posts.

GRC cable trough provides reliable support and protection to LV-MV power, signalling and communications cables.

GRC Cable Trough

GRC cable trough is the Network Rail standard for elevated troughing and trackside cable troughing. Standard sizes available C/1/7 up to C/1/43 to accommodate cable configurations with an internal width up to 350mm and internal depth up to 300mm.

BCM GRC cable trough and channel system includes radiused bends, channels, lids, stakes, brackets and accessories.
