: Duct/Innerduct abstracts and colors:

Fiber ducts are usually fabricated from HDPE (high-density polyethylene), PVC or added compound. They are usually in atramentous or gray. Cilia innerduct is usually orange or yellow.

:: Why usually cilia ducts and innerducts are corrugated?

Fiber ducts and innerducts are corrugated to accommodate the afterward benefits:

1. Decreasing affairs tensions during installation

2. Actual adjustable and can be acclimated in accession locations area abounding turns are involved

3. After installation, corrugated innerduct should be larboard for a day to acquiesce the innerduct to retreat aback into the aqueduct through its corrugated bounce action

:: The use of affairs tape

Fiber optic cable affairs band is preinstalled in cilia aqueduct and innerduct in the factory. This saves cogent time during the accession process. Aqueduct and innerduct can aswell be pre-lubricated in the factory, appropriately decidedly reduces affairs tensions.

:: Never angle over its minimum angle radius

Just like cilia optic cable, cilia aqueduct and innerduct aswell accept a minimum angle ambit spec. Never anytime should the aqueduct or innerduct be angled tighter than its minimum angle radius.

:: What is accurate radius?

The accurate ambit is the minimum angle ambit if the aqueduct is angled about a acknowledging anatomy such as in addition aqueduct or on a reel.

:: What is bottomless radius?

The bottomless ambit is the minimum angle ambit if the aqueduct has no acknowledging anatomy in the bend.

:: Benefits of application cilia duct

Fiber aqueduct protects the cilia cable and aswell provides an befalling for approaching cable admission and expansion. Cilia optic cable can be affairs into absolute duct. The aqueduct should usually be colossal to acquiesce approaching cables be pulled in.

:: Benefits of application cilia innerduct

Fiber innerduct provides aegis for the cilia cable from getting abashed by added companies’ cable accession operation. It aswell provides added aegis from the environment. Or cilia innerduct can be acclimated in old aqueduct installation.

:: Things to accumulate in mind

1. Install end plugs

After the cilia optic cable is installed into a aqueduct or innerduct, end plugs should be installed to accommodate a baptize seal. No bits should be able to access the aqueduct or innerduct, and absolute should consistently be maintained for the aqueduct or innerduct.

2. Aqueduct and innerduct should be appropriately sized for approaching amplification possibility

As always, planning for approaching amplification is acute for absolute acknowledged projects. A best of 40% ample arrangement is a acceptable convenance to follow. The aqueduct admeasurement should be added for continued accession lengths with abounding turns. A beyond aqueduct can advice to abate cable-pulling tensions. Standard aqueduct sizes alter from 3 to 8 inch ID and innerduct sizes alter from 0.75 to 2 inch.

:: The account of application aqueduct lubricant

Duct adipose can decidedly abate the cable’s accessory of friction, appropriately abbreviation the affairs astriction during cable affairs process. This is abnormally important in continued cable aqueduct pulls and pulls with abounding turns.

Duct adipose spillage should be bankrupt up as anon as accessible to anticipate blow back it is actual slippery. Manufactures’ recommended action for charwoman adipose provides acceptable apprenticeship on how to do the cleaning.
