In the age of the energy shortage, micro duct and cluster tube low cost and high quality has obvious advantages, by the telecommunication operators and highway investors, in recent years has been widely used in Europe and America, has been called the fourth generation communication pipeline products.
Product features:
1.reliable quality guarantee
2.flexible convenient network scheme
3.safe and fast laying cable way
4.Improve the resource utilization of existing pipeline
5.the best choice of Super capacity installment construction information channel
Product advantage:
1.material cost and construction costs are far less than The same number of silicone core tube
2.according to the market demand stage investment, Avoid optical fiber assembly density , improve underground pipeline resources;
3.Elastic expansion ability, meet sudden demand of optical fiber communication service.
4.construction simple, greatly shorten the construction period
5.compatible with existing optical fiber, adapt to the market development, technology stay on top.
6.Micro duct main performance indexes cluster tube core pipe
7.maximum traction's load (N) ≥3500 ≥300
8.tensile strength (Mpa) ≥15 ≥18
9.Breaking elongation rate (%)≥350 ≥500
2, cluster pipe : one or a few micro ducts, According to certain permutation order together , topical, PE sheathed layer, the products made of cluster, In the limited space in can accommodate more pipeline quantity
.
Structure features:
Through the color code, every micro ducts are defined in the cluster root the position of the tube , and convenient for construction, effectively avoid microtubules fault;
through special process and product formula, to ensure the micro ducts and the sheath layer relative separation, convenient for construction and the connection of internal micro ducts
through the cluster management layer color is different, or in the cluster tube sheath layer increased stripe logo to distinguish the mocro ducys in same the trench.
