Abstract
The utility model discloses a fire-resisting optical fiber composite cable, which comprises four alloy conductors. A refractory layer and an inorganic insulation layer are respectively and sequentially coated outside each alloy conductor. The four conductors coated with the inorganic insulation layers are arranged into a rhombus to form a cable core. A belting layer is coated outside the cable core. A filling layer which is made of ceramic magnesium oxide powder is arranged between the belting layer and the cable core, and among the four conductors. Optical fiber belts are arranged inside the filling layer. Loose sleeve tubes are sleeved outside the optical fiber belts. Fiber pastes are arranged between the loose sleeve tubes and the optical fiber belts. A sheath layer is extruded and molded outside the belting layer. According to the fire-resisting optical fiber composite cable, the electric energy transmission and the optical signal transmission can be carried out simultaneously; with the design of the refractory layer and the filling layer, the continuous operation time of the cable in high temperature environment can be well improved; and by adopting the optical fiber belts in cooperation with the protection functions of the fiber pastes and the loose sleeve tubes, the stability of the signal transmission can be ensured.
Description
Technical field:
The utility model relates to field of cables, relates in particular to a kind of fire safe type Optical Fiber Composite cable.
Background technology:
The existing power cable does not possess fire-proof function and transmission signals function; Therefore possess transmission of electricity and transmission photosignal function for needs; High temperature resistant, fire prevention, anti-environment had both been required; Require the applicable situation of height flexibility again, just must lay power cable and optical cable high temperature resistant, fire-resistant, anti-environment simultaneously, like this concerning some high-rises, national heavy construction, subway, track traffic, city network etc.; Aggravated the crowded state of pipe installation, the also corresponding waste that causes substantial contribution.
In addition, original cable adopts the loss percentage of optical fiber higher relatively, causes the information transmission to be interrupted, and brings unnecessary trouble.
The utility model content:
In order to overcome the deficiency of existing power cable function singleness, the utility model provides a kind of fire safe type Optical Fiber Composite cable, is applicable in specific (special) requirements, the abominable operational environment, has transmission of electricity and two kinds of functions of transmission photosignal.
The technical scheme of the utility model is following:
Fire safe type Optical Fiber Composite cable; It is characterized in that: comprise four alloy conductors, every alloy conductor is enclosed with flame retardant coating, inorganic insulation layer outward respectively successively, and the outer diamondwise of four alloy conductors of parcel inorganic insulation layer is arranged and constituted cable core; Cable core is wrapped with belting layer; Between described belting layer and the cable core, be equipped with the packed layer that ceramic magnesium oxide powder constitutes between four alloy conductors, be provided with fibre ribbon in the packed layer, fibre ribbon is with loose sleeve pipe outward; Be provided with fine cream between pine sleeve pipe and the fibre ribbon, the outer extrusion moulding of described belting layer has restrictive coating.
Described fire safe type Optical Fiber Composite cable is characterized in that: described flame retardant coating adopts the overlapping wrapped formation of synthetic mica tape.
It is following that the utility model is compared the beneficial effect of existing power cable:
The utility model realizes that electric energy and light signal transmit simultaneously; The design of flame retardant coating and packed layer improves cable well and under hot environment, continues regular hour work, and fire protecting performance is superior, in addition; Adopt fibre ribbon to cooperate the protective effect of fine cream and loose sleeve pipe, ensured the stability that signal transmits.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1:
Fire safe type Optical Fiber Composite cable; Comprise four alloy conductors 1, every alloy conductor 1 outer flame retardant coating 2, the inorganic insulation layer 3 of being enclosed with successively respectively, four alloy conductors, the 1 outer diamondwise of parcel inorganic insulation layer 3 is arranged and is constituted cable core; Cable core is wrapped with belting layer 4; Between belting layer 4 and the cable core, be equipped with the packed layer 5 that ceramic magnesium oxide powder constitutes between four alloy conductors 1, be provided with fibre ribbon 6 in the packed layer 5, fibre ribbon 6 is outer to be with loose sleeve pipe 7; Be provided with fine cream 8 between pine sleeve pipe 7 and the fibre ribbon 6, belting layer 4 outer extrusion moulding have restrictive coating 9.
