Jinhua IDSS (Optical Cable Blocking)
Release time:
2020-02-09
It has been more than 10 years since the implementation of fiber optic cable sealing according to national and relevant regulations. At present, cement is commonly used for sealing in the market, but due to some characteristics of cement, it cannot meet the sealing requirements. Later, when the fireproof mud sealing was replaced, it was still an alternative sealing product that did not achieve the expected effect. The underground well for laying optical cables is a very small cubic well, and there is a cable underground well for laying optical cables every 50-60 (unit meters). Sometimes, the optical cables and cables are located in the same well, so the problems that need to be solved for sealing the cable well for laying cables also exist. Due to the particularity of the cable well for laying optical cables, the sealing requirements have increased. (1) Prevent sediment from filling pipelines. (2) Prevent small animals (mice) from corroding the optical cable or entering the user area along the optical cable pipeline. (3) Prevent water from entering the pipeline. Implementation plan (1) Clean the pipeline wall and optical cable to remove previous sediment, cement, and fire-resistant mud residues. (2) Use inflatable cable duct sealing device (IDSS) for sealing and sealing.

reason
The underground well for laying optical cables is a very small cubic well, with an underground well for laying optical cables set up every 50-60 (unit meters). Sometimes, the optical cables and cables are located in the same well, so the problems that need to be solved for sealing the cable well for laying cables also exist. Due to the particularity of the cable well for laying optical cables, the sealing requirements have increased.
(1) Prevent sediment from filling pipelines.
(2) Prevent small animals (mice) from corroding the optical cable or entering the user area along the optical cable pipeline.
(3) Prevent water from entering the pipeline.
Implementation plan
(1) Clean the pipeline wall and optical cable to remove previous sediment, cement, and fire-resistant mud residues.
(2) Use inflatable cable duct sealing device (IDSS) for sealing and sealing.
