The inner sheath is thermoplastic polyester elastomer inner sheath, and the maintenance set is polyethylene outer sheath；Light in the microbeam pipe
It blocks water powder between fine beam filled with dry type.
It further comprise the cable core include multiple light units and cladding in one preferred embodiment of the utility model
The water blocking tape layer of all light units is filled with dry type waterproofing rope between the light unit in the water blocking tape layer.
It further comprise that the water blocking tape layer includes polyester yarn layer and is attached in one preferred embodiment of the utility model
Water absorbing resin particle on polyester yarn layer.
It further comprise being embedded with tear rope in the inner sheath in one preferred embodiment of the utility model.
It further comprise being embedded with reinforcer in the oversheath in one preferred embodiment of the utility model.
In one preferred embodiment of the utility model, further comprise the reinforcer be waterproofing type non-metal reinforcement member or
Person's composite water-stopping band.
It further comprise that the waterproofing type non-metal reinforcement member is fragrant for waterproofing type in one preferred embodiment of the utility model
Synthetic fibre silvalin.
The all dielectric self-supporting microbeam pipe ADSS optical cable of one, the utility model, optical cable with high light fibre density and
Still ensure that lesser outer diameter and lighter optical cable weight in the case where larger capacity, the cable connection time can shorten 50% with
On, have the characteristics that small size, easy stripping, easily separated, weight is small, total cross-section is impermeable, optical cable heatproof require up to -30 DEG C~+
70 DEG C, flat pressure is allowed to reach 1200N/10cm, allows drawing force to reach 1300N, it is complete that permeability performance meets TEC60794-1-2-F5B
Section is impermeable.
Secondly, thermoplastic polyester elastomer can be made the microbeam pipe of ultra-thin wall thickness, and have preferable stripping, good
Good heat resistance, it is ensured that optical cable with high light fibre density and larger capacity in the case where still ensure that lesser outer diameter and
Lighter optical cable weight.
