Polymer Cable Trough & Lid | TTS 135 Series
Polymer Cable Trough
TTS 135 Series
Network Rail PADS Approved – Certificate Of Acceptance PA05/05145
TTS 135 Series of polymer cable trough is suitable for LV MV HV rail cable protection in applications such as ground installations, wall mounted or elevated on posts. The TTS 135 Series includes straight trough, 45-degree angle trough, T-junction trough and gradient trough pieces.
Green Trough from TTS, including base and lids, are manufactured from recycled synthetic resin to provide versatile cable ducting systems for power, signal and communications cables.

TTS Polymer Trough
The closest concrete trough equivalent size to the TTS 135 Series is C/1/7. However polymer cable trough is 82% lighter with a 20% more capacity than the equivalent concrete trough. Where cable capacity is not the prime concern, but weight saving is, the TTS 135 Series provides the perfect solution for conformance with Manual Handling & Operations Regulations of troughs and lids.
