GRP Cable TroughingGRP Trough

Protection of Rail Cables & LV MV HV Power Infrastructure Using Cable Troughing Systems | GRP

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.

MITA also offer a range of cable containment and support accessories for GRP cable troughs including steel posts and brackets.

Why GRP Trough over Concrete or Steel?

GRP trough offers between 30-40% less installation costs – with easier cutting, drilling and no deburring, painting or earthing required.

The GRP solution offers a far easier installation, without the need for painting, earth bonding or special tools. Fast installation with wide selection of pre-manufactured fittings. Supplying 6m or 3m lengths of trough reduces amount of couplers required.

Composites are corrosion resistant and maintenance free. GRP cable management products from MITA are designed and manufactured to withstand the majority of chemicals and extreme weather – without requiring further maintenance. This ensures a long lifetime and lower maintenance than steel or concrete trough.

Density and weight of GRP cable troughing systems are significantly lower than steel (70% lighter than steel, 90% lighter than concrete) with reduced on-site handling requirements. Composite materials are excellent insulators, do not require earthing and have a thermal conductivity 1/60 of a steel type cable trough product.

GRP is available with zero halogen, low conductivity and self extinguishing material that is also low smoke classified for fire security. Not only this, but it is effective at temperatures between -140 C to +120C.

Tension, flexure and compression strength of GRP material is approximately 20 times that of steel with much greater safety factors. Composites do not permanently deform under high loads. GRP trough offers reduced risk of staff injuries due to its lightweight, easy to cut, no hot works requirement, no deburring and no sharp edges meaning better Health and Safety.
