Abstract
The invention discloses a low-voltage composite cable for a thermal insulation optical fiber of an optical unit. The low-voltage composite cable comprises a cable core and an outer protection layer extruded at an outermost layer. The low-voltage composite cable is characterized in that the cable core is formed by a plurality of electric unit, a thermal insulation optical unit and a thermal insulation filling combination partially coated outside the thermal insulation optical unit. With the adoption of the low-voltage composite cable, the optical unit of the cable has the thermal insulation function due to the thermal insulation design of the optical unit, so that the heat conduction of the electric units to the optical unit can be effectively reduced; the working temperature of the optical unit can be ensured; and the problem that the working temperatures of the light unit and the electric units are compatible can be effectively solved. The low-voltage composite cable for the thermal insulation optical fiber of the optical unit combines functions of communication and electric power, so that the multi-network combination can be effectively realized; and the cost of the network construction can be reduced. The low-voltage composite cable is a multi-network combined product with highest cost performance.
Description
Technical field
The power cable field that the present invention relates to communicate by letter, refer to a kind of smooth unit heat insulation optical fiber low pressure composite cable especially.
Background technology
Optical fiber composite low-voltage cable is as one of important cable products in the intelligent grid construction, it has merged the function of communication and electric power, the many nets that can effectively realize telecommunications network, electric transmission network, television network, the Internet etc. merge, reducing the cost of networking, is one of present cost performance the highest " many nets merge " product.
At present, when optical fiber composite low-voltage cable is manufactured, after employing electric unit, the compound stranding in light unit, extrude the structural design of sheath, this design can meet instructions for use in common laying under environment.But in some Special use occasions, in the situations such as large as cable load, overload, the electric unit caloric value is large, the light unit is subject to the impact of heat, temperature raises, thereby the transmission performance of light unit is impacted, thereby causes light unit and the electric unit working temperature problem of compatibility mutually.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of smooth unit and has heat insulating function, effectively reduce electric unit conducts light unit heat, guarantee the working temperature of light unit, thereby efficiently solve the optical fiber composite cable of light unit and electric unit working temperature phase compatibling problem.
A kind of smooth unit of the present invention heat insulation optical fiber low pressure composite cable, comprise cable core and outermost outer jacket, and described cable core is combined by several electric units, a heat insulation smooth unit and the local heat insulation filling that is coated on outside heat insulation smooth unit.
Described electric unit consists of the electric insulation core.
Described heat insulation You Guang unit, smooth unit and wrapped glass fibre heat-insulation and heat-preservation band formation outside the light unit.
Described heat insulation filling consists of ceramic fibre circle sennit.
Described outer jacket is that thermosetting or thermoplastic plastics extrude sheath.
Beneficial effect of the present invention is:
1, the present invention has by special structural design and use ceramic fibre circle sennit and the glass fibre heat-insulation and heat-preservation band that heat-proof quality is good, make the light unit of cable have heat insulating function, effectively reducing electric unit conducts light unit heat, guarantee the working temperature of light unit, thereby effectively solve light unit and the electric unit working temperature problem of compatibility mutually.
2, outer jacket is that thermosetting or thermoplastic plastics extrude sheath, realizes the defencive function to cable core structures such as light unit and electric units.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of smooth unit of the present invention heat insulation optical fiber low pressure composite cable, comprise cable core and be extruded in outermost outer jacket 4, described cable core is by several electric units 1, heat insulation smooth unit 2 and locally be coated on the 2 outer heat insulation fillings 3 of heat insulation smooth unit and combine.
The invention provides version and the implementation method of a kind of smooth unit heat insulation optical fiber low pressure composite cable; the above is only preferred implementation method of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also make some improvement, these improvement also should be considered as protection scope of the present invention.
