Cable Trough
Cable Trough | GRC | GRP | Concrete Cable Protection Trough For LV MV HV Rail Power, Signal & Telecoms
Cable trough provides both a high security shallow trench for cable protection and management with support for post elevated cable routes – we distribute a range of cable troughing systems manufactured in GRP, GRC or concrete for all infrastructure installations including railway, highway, power, telecoms and utility projects.
Thorne & Derrick working with Anderton, BCM and MITA distribute cable troughs from stock designed to protect underground and elevated cables including LV-HV power, signalling and telecoms up to 33kV.
Anderlite Cable Trough | 30% Weight Reduction Over Traditional Route Systems
Anderlite reduces the risk of manual handling concerns and minimises labour requirements. The general reduction in the weight of the cable trough product reduces transport costs by up to 20%, lessening the carbon footprint and providing cost savings over traditional systems. The unique cementitious mix design utilises up to 7% of recycled materials which reduces the environmental impact of the product – it is easy to install with sufficient mass to avoid pinning.
Resin Types for GRP Trough
The MITA range of GRP cable trough and support systems provide industrial management for cables located in harsh, hazardous and corrosive environments with explosive atmospheres.
MITA offers 4 main resin types to accommodate the requirements of various industrial applications which can be in chemically aggressive locations with demanding heated environments.
Material Selection | The fibres and composition provide different levels of corrosion resistance – when considering a particular resin system for an intended environment, the degree of exposure, the concentration of the corrosive element and the temperature of the environment must be determined. The degree of corrosion resistance on the surface is achieved by the use of a surface mat or veil.
Thorne & Derrick can assist with the selection and specification of cable trough and support management systems for all onshore and offshore industrial sectors.
 | POLYESTER Type 2 | Referencing Convention: Ending with PY2 This type of polyester is for general trough applications, is resistant to corrosion suitable in industries using heavy chemical and caustic materials, and resistant to UV light by nature. |
| POLYESTER Type 1 | Referencing Convention: Ending with PY1 This type of polyester has better fire retardance which makes the cable trough suitable for railway, trackside and any other application requiring UL94 compliance and 5VA classification. | |
| POLYESTER Type 1 Carbon Loaded | Referencing Convention: Ending with PY1C This type of polyester has anti-static properties as it contains carbon powder. It, therefore, requires grounding. It is for on-shore and off-shore oil and gas applications which are classified as explosive environment. | |
| MODIFIED ACRYLIC | Referencing Convention: Ending with MX This type of polyester cable trough has anti-static properties as it contains carbon powder. It, therefore, requires grounding. It is for on-shore and off-shore oil and gas applications which are classified as explosive environment. |
Rail Cable Trough Protection
| Signalling | Power (SWA Armoured) |
| Medium & High Voltage Power MV HV | Telecoms |
| Track Feeder | Network Rail & LU London Underground Approved |
GRP, GRC & Concrete Cable Troughs
PADS Approved
All rail cables are protected against accidental damage or vandalism whilst remaining easy to access if maintenance, jointing or future upgrade is required.
Cable trough ensures the ground stability of trackside and lineside cables without experiencing gradual displacement, “snaking”, caused by ballast disruption from passing train movements.
Thorne & Derrick range of protective troughs are supplied in a range of sizes (diameters and depths) and specifications to suit the installation and capacity needs of the client and application. For rail cables in tunnels Thorne & Derrick supply cable hangers to provide support for single and multiple runs of power and signalling cables, the J-type hangers are available in galvanised steel or a non-metallic nylon material conformant with London Underground 1-085 specification.
GRP cable trough manufactured by MITA is used for trackside protection, support and management of rail power, signalling and telecoms cables – this includes 11kV/33kV high voltage armoured/unarmoured power cables to British Standards (BS6724 BS6622) and 25kV/44kV trackfeeder cables providing DC and AC electrification in accordance with Network Rail specification NR/PS/ELP/00008.

Network Rail PADS Approved Cable Troughing
Trough and protective lids with Network Rail PADS approvals ensure protection of trackside power and S&T cables on the UK rail infrastructure – this includes LV copper and aluminium dc traction power and medium/high voltage (MV-HV) power cables supplying 11kV, 25kV and 33kV electricity distribution.
Troughing systems for Network Rail NR/PS/SIG/00005 (formerly RT/E/PS/00005) signalling cables provides high strength protection to vital rail cables – the easy to install trough systems include channels, lids, stakes, brackets, bends and tee’s to enable the containment and installation of rail signalling cables.
PADS
PADS (Parts and Drawing System) numbers relate to the Network Rail register of individual product references which comprise an approved product database for use on trackside, station, underground, tunnel and infrastructure applications on the UK rail system.
The Network Rail PADS system preserves rail safety, product compatibility, reliability and prevents against risk elements damaging the operationality of the rail system through the installation of equipment not “fit for purpose”.
