Demand for the underground installations
of power cable and telecommunication cable are increasing tendency
to secure safety and space as well as beautification in rural, industrial
and residential area according to the modern industrial and municipality
congestion. The conventional underground cable being applied have
been Hume pipe, Steel pipe And PVC pipe, that are straight, heavy
and being caused lots of disadvantages in work sites, as such materials
required numerous connections couplings due to short length of ducts
(Max. 6 meter/PVC). In addition, it has been causing increase of
project cost and troubles due to long period of installation time.
COD has successfully solved all such difficulties and disadvantages.
COD is product of specific spiral formed, which solved the vulnerability
of compressive load of conventional straight PE pipe to be several
times stronger than that of conventional pipes, increasing the efficiency
and flexibility. COD promises to meet the requirement of end users
with its considerable profitability, endurance and economy.

|
1. Better Flexibility
Owing to spiral forming of product, COD is easy to bend without
special bending efforts, and easy to by-pass or over pass hurdles
along with the duct line.
|
|
 |
2. Lengthy pipe
Owing
to lengthy and coiled on drum, it reduces considerable labor cost
as well as working period to install by waving numerous connections
in between two manholes but one time installation.
On top of it, COD never require inserting
of inner duct into outer duct owing to
built-in production of multiple inner ducts.
|
|
|
3. Lighter in
weight
Owing to the lighter gravity (0.95:1.43), COD is considerably
lighter, which offers benefit in handling in the work site and
transport-ation compare to the conventional duct.
|
|
 |
4. Stronger
Owing to the readily built-in multiples numbers of inner ducts perfectly
without any loose space inside of spiral outer duct, COD offers considerable
advantage in terms of compressive load.
5. Safety
COD stands safe in Earthquake and Land Subsidence owing to its strong
compressive load and flexibility. |
|
 |
6. Better resistance
against chemicals and better endurance:
COD lasts semi-permanently owing to resistance against chemicals
and corrosion
free from salt water or wetland.
|
|
| |
7. Easy insertion
of copper & optic fiber cables
COD facilitate easy insertion of cables up to
the maximum-coiled length owing to perfect alignment of inner
ducts and less friction,
as it has no connections. In addition,
it enables to extend the manhole distance.
On top of it, COD enables to insert cable up to 75% of inner
diameter of inner duct, while conventional duct allows only 50%
of it.
|
|
|
8. High Reliability
COD is non-conductive of electricity,
and therefore, it is ideal to apply for
power cable duct.
9. Cost Efficiency In consideration of all advantages
and efficiency, COD offers cost efficiency throughout all consecutive
work stages and endurance.
