Abstract
The utility model relates to the technical field of an optical cable, and particularly to a mining optical cable. The structure of the mining optical cable comprises a single-groove frame, an optical fiber and a sheath. The single-groove frame is provided with an accommodating groove which is used for accommodating the optical fiber. The sheath is sheathed outside the single-groove frame. A watertight layer and a steel band layer are provided between the sheath and the frame. The sheath is composed of an inner protective layer, a glass fiber layer and an outer protective layer for flame retardation from inside to outside. The single-groove frame is internally provided with a reinforcing member. The mining optical cable provided by the utility model has high side pressing resistance, and furthermore optical fiber branching can be performed without peeling the whole optical cable.
Description
Technical field
The utility model relates to optical cable technology field, particularly optical fiber cable for mine.
Background technology
The environment for use of optical fiber cable for mine is very complicated, be mainly used in mine, the tunnels such as colliery, gold mine, iron ore, optical fiber cable for mine is in use wanted level to lay with vertical to lay, optical fiber cable for mine not only needs outside the good communication performance of optical fiber cable simultaneously, also needing to have good anti-flammability, protection against rodents property, particularly mine is Frequent Accidents ground, still guarantees that communication is unimpeded when guaranteeing unexpected the generation, reduce the loss, this requires optical fiber cable for mine also to need that good mechanical property is arranged.And at present optical fiber cable for mine adopts, be central beam optical fiber cable for mine and layer-twisted type optical fiber cable for mine, in use come with some shortcomings: (1) optical cable needs the cross section of the whole optical cable of stripping in use, strong to the destructiveness of optical cable, and is unfavorable for branch; (2) lateral pressure resistant is indifferent.
Summary of the invention
The utility model provides a kind of lateral pressure resistant ability by force and does not need the whole optical cable of stripping can carry out the optical fiber cable for mine of fiber optic tap.
Provide optical fiber cable for mine for this reason, comprise single groove skeleton, optical fiber and sheath, single groove skeleton offers a storage tank for optical fibre, sheath is sheathed on outside single groove skeleton, be provided with water blocking layer and steel belt layer between sheath and single groove skeleton, sheath is arranged with from inside to outside sheath, fiberglass layer and, for fire-retardant outer jacket, in single groove skeleton, is provided with reinforcement.
Wherein, be provided with and tear rope between fiberglass layer and outer jacket.
Wherein, sheath is the PE sheath, and outer jacket is the LSZH outer jacket.
The utility model has adopted single groove skeleton structure, during branch, only need optical cable lateral section stripping to get final product, can not destroy the integrality of optical cable, be easy to branch, further, because single groove skeleton has only been offered a groove, single groove skeleton has still kept whole stronger mechanical property, thereby guaranteed the lateral pressure resistant ability of optical cable, the energy level lays with vertical and lays, and reinforcement and fiberglass layer make optical cable have good tensile property, water blocking layer guarantees that optical cable has good water preventing ability, the flame-retarding characteristic of outer jacket guarantees that optical cable has good anti-flammability, sheath and steel belt layer can guarantee that optical cable has good protection against rodents property jointly.
To sum up, the utlity model has good water preventing ability, anti-flammability, protection against rodents property and mechanical property, can be suitable for complicated environment for use, the utility model does not need again the whole optical cable of stripping can carry out fiber optic tap simultaneously, be easy to branch, and the performance of lateral pressure resistant is good.
The accompanying drawing explanation
Fig. 1 is the structural representation of optical fiber cable for mine.
Embodiment
Optical fiber cable for mine, comprise single groove skeleton 1, optical fiber 2 and sheath, single groove skeleton 1 offers a storage tank for optical fibre 3, sheath is sheathed on outside single groove skeleton 1, be provided with water blocking layer 5 and steel belt layer 6 between sheath and single groove skeleton 1, sheath is arranged with from inside to outside PE sheath 7, fiberglass layer 8 and, for fire-retardant LSZH outer jacket 9, in single groove skeleton, is provided with reinforcement 4, is provided with between fiberglass layer 8 and outer jacket 9 and tears rope 10.
