We supply a wide range of twinwall duct coil to suit your needs. This twinwall duct coil is 150/178mm and 6m long – suitable for telecoms use.
Why purchase twinwall ducting?
At Cotterill’s we offer an advanced and comprehensive range of ducting. We can help meet the needs of all civils, utility and telecommunication markets. These ducting systems offer the advantages of a lightweight flexible product combined with high strength and durability.
These ducts are manufactured in polyethylene the pipe is normally supplied in either 6m lengths or 50m coils. This twinwall duct is made from HDPE (High Density Polyethylene), being both strong and resistant to corrosion. Like our flexible duct, it is designed to meet the current compressive strength requirement of the Highways Agency. The external corrugated profile gives the product added strength and the internal bore is smooth to prevent cables from snagging.
You should always choose a diameter that allows plenty of room within the duct to allow the cable or cables to be drawn through smoothly. The internal wall is smooth allowing cables/pipes to be pulled through easily and prevent snagging, whilst the external wall is corrugated which can withstand high compressive forces and gives added strength during installation. This duct is also both BBA approved and kitemarked certified to BS EN 61386-24, providing peace of mind.
If you plan to run any type of service underground, it should be running inside a duct system. A duct is designed to protect the service cable or pipe from damage and alert others to the presence of duct in the ground.
Why purchase green/telecoms twinwall ducting?
Green twinwall ducting is used for ducting telecoms supply pipes. This should ensure that the pipe is unaffected by either frost or potential surface digging.
