Composite Cable/Tunnel Trench Cover
Composite cable/tunnel trench cover
Thermoset polymer composite trench cover, formed in a single high-temperature, high-pressure moulding cycle. Used over cable trenches and tunnel service ducts where weight savings and electrical isolation are priorities.
Features
01
Strong electrical and mechanical properties, suiting live cable environments
02
Chemically resistant, performing in damp, salty and contaminated trenches
03
Over 50% lighter than the equivalent cement-based cover
04
Does not drop slag, so it stays clean and safe in pedestrian areas
05
Maintenance-free, with custom colour and finish options
