OPTICELL FAQs

Available for the following cables:

  • Laying of communication cables: optical cable, coaxial cable, copper wire, Cat 5 cable
  • Power cable, control cable, light cable(Please consult our sales department for cases with heavy cable weight)
  • Cable laying indoors and outdoors at factories

OptiCell has been used in all of the above cable installations.

The maximum outer diameter of the cable that can be installed on the 4418 type is 18 mm, 22 mm on the 5222 type, and 28 mm on the 6428 type. However, in all cases this maximum outer diameter is not recommended. It may be affected by the size of the outer tube, the thickness of the existing cable, the pulling length, the change in height, the number of bendings and the degree of bending. The best solution is to lay the above-mentioned maximum outside diameter cable in one cell, and to lay a smaller cable in the other cell. If you have any questions about OptiCell or cable size under specific usage, please do not hesitate to contact us.

OptiCell can be laid in any pipeline as long as space is secured. For example, in some cases, two tubes are removed from the outer tube where three conventional sheaths are already laid, and a 3-cell OptiCell is laid there. In this case, the towing length was about 300m and there was one bend of about 90 °, but it could be laid by hand.

The maximum towing length at this time is about 1,830m. OptiCell has much better traction capacity than existing inner ducts (pods), so you may be able to guide a considerable length. However, OptiCell's traction length is affected by how the duct is configured. The number of vertical and horizontal bends, the presence or absence of existing cables and sheaths and their placement, and the presence of sediments in the outer tube. Extremely bad conditions can affect the traction length of an OptiCell, but rarely its traction capacity is denied.

The OptiCell, which has been used in many constructions to date, has been laid even at sites where there is some 90 ° bending up and down. Follow the recommended OptiCell installation method. If you have any questions about the use of OptiCell in your planned construction, please contact us. OptiCell's sales staff will advise on the installation method according to the situation.

OptiCell requires a tool called “swivelrdquo; to lay it. With the right tools and laid in the recommended way, OptiCell will not twist or become entangled. For details, see the page on how to lay.

Until now, the biggest concern when laying new cables where existing cables are laid was whether to damage the coating of each other when laying. However, with OptiCell, the cables do not touch each other during the installation, eliminating the risk of damage.

It can be laid as long as there is no serious problem, but depending on the degree of twisting of the existing cable, the pulling force may increase. If the degree of twist of the existing cable is such that it blocks the inside of the pipeline, any inner duct (pod) cannot be laid. However, if there is enough space for the OptiCell to pass, the OptiCell will allow the most cable runs. The difficulty with this problem is determining the degree of torsion at the bend.

When laying in the ground, mud and water are obstacles to the laying, but OptiCell performs at least as well as the existing inner ducts. In the case of water, it is not a problem unless it is a large amount and long distance. Although it may affect the traction force to some extent, it can be said that it has less effect than the conventional inner duct (pod). OptiCell is made of mesh fibers and has a water resistant property. If the pipeline is flooded with water, it will be easier to lay than the existing inner duct (sheath pipe) because it is water-permeable because of its fibrous nature. In the case of mud, it becomes a big problem depending on its hardness and amount. If there are few deposits and a small amount, you will be able to break the mud with a rod. However, if a large amount of mud accumulates over a long distance, it may not be possible to lay the OptiCell. Of course, in such a case, the conventional inner duct (pod) cannot be used. We recommend flushing or removing mud from outer pipes that have a continuous flow of mud before laying the OptiCell. And put a thick rope in each cell. This rope leaves the path in the future when laying cables, even if mud enters the outer tube again.

The following methods are commonly used:

  • Inflation bag (not 100% waterproof)
  • Termination plug (100% waterproof)
  • Putty etc. can be used for simple sealing

Not at this time.

Available. OptiCell is available in a standard type and a flame retardant type.

It does not change over the years unless exposed to sunlight for an extended period. OptiCell reels shipped from the factory are packaged in UV-resistant packaging. The seams are bonded with a bond and are resistant to water, seawater and petrochemicals.

OptiCell does not respond to these.

Slipperiness will not be lost or degraded over time.

Not all OptiCell products have a silicon-based additive, which is necessary. However, when laying in extremely difficult environments, for example, long distance laying, simultaneous laying of multiple OptiCells, multiple 90 ° bends, severe undulation, sediment such as mud in pipeline For example, it is recommended to apply additional lubricating oil.

Additional lubricant is not required as the OptiCell product itself is lubricated. However, you can apply more if you want to lay the cable more easily.

OptiCell uses the best materials because it is used underground. Due to its physical properties, OptiCell is extremely tough and resistant to wear and temperature changes. The materials used in OptiCell have excellent resistance to fuels such as jet fuel, gasoline, light oil and natural gas. OptiCell has better physical properties and chemical resistance than polypropylene and polyethylene. The materials used do not degrade even when attacked by underground organisms.

OptiCell has a tensile strength of approximately 1,300 kg for a 5222 x 3 cell. The breaking strength of the pull tape included in the cable tow is 565 kg.

No. This is not the case because OptiCell has less than half the coefficient of friction of high-density polyethylene.

Prolonged exposure to water, seawater or mud has no effect on the lifetime of the OptiCell.

OptiCell has a melting point of 215 ° C. In the United States, black fiberglass outer tubes are often used in bridges, but the temperature inside the outer tube can easily exceed 50 ° C due to exposure to direct sunlight or reflected light from the water surface under the bridge . However, OptiCell is used without any problems in such an environment.

OptiCell itself does not freeze in the global environment. However, if the water that has entered the pipeline freezes, problems may occur, as with inner ducts made of other materials.

The lubricating oil used in OptiCell does not freeze even at low temperatures and does not run down due to heat. Lubrication is not lost due to temperature and environmental changes.

OptiCell is a flexible fibrous inner duct, so the cell is not airtight. It is not currently available for this method.

OptiCell's production plant has acquired ISO9001: 2015.

OptiCell is essentially an insulator and cannot be detected by metal detectors. Historically, the most common way to be detectable was to bury a detectable pull tape or rope along with the pipe during pipework. However, if this pull tape is used when laying cables, it will not be detectable thereafter. To solve this problem, we have developed a product in which a thin, detectable cable is attached to the OptiCell. I try not to do it.

The prints are made with inkjet technology and will not be exposed to water or ooze to the extent of being soaked when laying. However, prints are not resistant to UV light and will gradually fade when exposed to sunlight for extended periods (months). Therefore, the reels are covered with UV-resistant wrap to protect the OptiCell and prints prior to installation.

The length of the OptiCell and the pull tape are indicated every 2 m. In addition, the length of each 1 m is indicated on the pull tape attached to each cell.
