HDPE cable ducts
The cable ducts made of high density polyethylene (PE-HD) are intended for mechanical protection of fibre optic and metal cables. They are used on installations of local and long-distance telephone networks, cable television transmissions, information transfer networks, etc.
PARAMETERS
| OUTER DIAMETER: | 20 – 50 mm |
| INSIDE DIAMETER: | 15,4 – 42 mm |
| WALL THICKNESS: | 2,3 – 4 mm |
| WEIHGT: | 122 – 552 g/m |
| LENGTH ON A DRUM: | 1 100 – 7 800 m |
| COIL LENGTH: | 300 – 2 000 m |
FUNCTION
| serves to form cable conduits for subsequent installation of cables (by pulling or blowing)
| provides a protection for the installed cables
| permits an easy replacement of cables without the necessity to dig the cables out
ADVANTAGES
| increased efficiency in network building
| ease of connecting the ducts with the aid of couplings
| a print indicating length of cables gives information about the length of the cable installed
| possibility of using ducts of different colour allows to distinguish cables when several cables are installed in a single trench
| strength imparting the duct compression resistance
| heat resistance providing satisfactory mechanical properties in the temperature range from -20 to +55 °C
long durability
| resistance to moisture, oil, petrol, rodents and other unfavourable factors that may affect the duct underground
