Abstract
The utility model discloses a kind of layer-twisted type flame-proof cable, it is characterised in that：Including more light units, at least two gasket for packings, a center reinforcemen and external sheath layer; the protective layer of the light unit is stainless steel tube; the more light units and at least two gasket for packings are twisted to being twisted into cable core with SZ or S; the center reinforcemen is placed in inside cable core, and the external sheath layer is coated on outside cable core.The utility model has the advantages that：Fire resistance is good, light unit is easily distinguished, applied widely.
Description
Technical field
The utility model is related to a kind of flame-proof cable, specifically, be related to it is a kind of using stainless steel tube as protective layer
Layer-twisted type flame-proof cable, belong to optical fiber cable technical field.
Background technology
When using stainless steel tube design flame-proof cable, center tube structure is usually designed as, i.e. stainless steel tube optical unit exists
Optical cable centre position.Though this structure can meet fire resistant requirements, fiber number is limited by structure, when core number is more than 12 core
Optical fiber need to be distinguished using colo(u)r streak or optical fiber colour circle, not only production process is numerous and diverse, and there is also many inconvenience in terms of fibre junction.If
Stainless steel tube optical unit carries out stranding in the form of twisted, then can increase density of optic fibre, meet under different service conditions
Customer demand.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of fire resistance is good, light unit is easily distinguished, is applicable
The wide layer-twisted type flame-proof cable of scope.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of layer-twisted type flame-proof cable, including more light units, at least two gasket for packings, a center reinforcemen and outer shield
Jacket layer, the protective layer of the light unit are stainless steel tube, more light units and at least two gasket for packings are twisted to strand with SZ or S
Cable core is synthesized, the center reinforcemen is placed in inside cable core, and the external sheath layer is coated on outside cable core.
Further, the color of the gasket for packing is different.
The differentiating method of light unit is：Due to two added in cabling process or the gasket for packing of more than two, these
The color of gasket for packing should be incomplete same, if the clockwise direction for providing these colors is cable core A ends, the inverse time of these colors
Pin direction is cable core B ends, and cable core A ends carry out clockwise direction numbering by original position of a certain color filling rope, at cable core B ends
Counter clockwise direction numbering then is carried out by original position of the color filling rope, same sequence number is then same root light unit, is solved
The differentiation problem of same size light unit.
The utility model has the advantages that：It is simple in construction, fiber number is big, fire resistance is good, light unit is easily distinguished, is applicable
Scope is wide.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is structural representation of the present utility model.
Wherein, 1, external sheath layer, 2, gasket for packing, 3, center reinforcemen, 4, stainless steel tube.
Embodiment：
As shown in figure 1, a kind of layer-twisted type flame-proof cable, including four light units, two gasket for packings, 2, centers are strengthened
Part 3 and external sheath layer 1, the protective layer of light unit use stainless steel tube 4, four light units and two gasket for packings with SZ or S twist to
Cable core is twisted into, center reinforcemen 3 is placed in inside cable core, and external sheath layer 1 is coated on outside cable core.The color of two gasket for packings 2 is each
Differ.Because the color of two gasket for packings added in cabling process should be incomplete same, if providing the suitable of these colors
Clockwise is cable core A ends, then the counter clockwise direction of these colors is cable core B ends, cable core A ends using a wherein color filling rope as
Original position carries out clockwise direction numbering, is then carried out counterclockwise by original position of the color filling rope at cable core B ends
Numbering, same sequence number is then same root light unit, solves the problems, such as the differentiation of same size light unit.
The utility model innovation using to the more stainless steel tubes and at least two gasket for packings progress of SZ or S twisting process into
Cable, form layer-twisted type stainless steel tube flame-proof cable cable core.Optical fiber is formed secondary remaining long in cabling process, improves flame-proof cable
Ess-strain performance.The gasket for packing of two or more than two are added in cabling process, the color of these gasket for packings is incomplete
It is identical, and carry out AB petiolareas point and light unit differentiation according to these color sequences.The differentiation for solving same size light unit is asked
Topic.The use of layer-twisted type technique, the fiber number of stainless steel tube flame-proof cable is considerably increased, the spy larger to message volume
Different region is particularly suitable.
