Description
Technical field
The utility model belongs to power cable field, is specifically related to a kind of ceramic fireproof cable.
Background technology
Cable refers generally to be made up of the conductor of one or more mutually insulated and outsourcing insulating protective layer, and electric power or information are transferred to the wire at another place from one.The application places of cable is relatively complicated, and the safe operation of place to cable of these complexity proposes challenge.It is one of of paramount importance factor affecting cable running safety that fire is suffered from, and how ensureing cable normal operation in high temperature environments, is the cable manufacturing enterprise technical issues that need to address.
Existing cable is because of reasons such as structural designs, and its fire-proof and water-proof and insulation property are generally poor, under hyperbaric environment, often punch-through can occur.
Utility model content
The utility model is intended to overcome the deficiencies in the prior art part and provides a kind of structure simple, and long service life, reliability is high, good insulating, is suitable for the ceramic fireproof cable that voltage range is wide.
For solving the problems of the technologies described above, the utility model realizes like this.
Ceramic fireproof cable, it comprises insulating sleeve and several cable core unit; Described several cable core unit is positioned at insulating sleeve; Coated first Ceramic silicon rubber fireproof layer on described cable core unit; Coated insulation layer on described first Ceramic silicon rubber fireproof layer; Coated watertight composition on described insulating barrier; Clad metal screen on described watertight composition; High temperature resistant packed layer is provided with between the outer wall of described several cable core unit and insulating sleeve inwall; The second Ceramic silicon rubber fireproof layer is provided with between described high temperature resistant packed layer and insulating sleeve inwall.
As a kind of preferred version, high temperature resistant packed layer described in the utility model can adopt glass fiber winding arrangement.
Further, the utility model can be provided with insulation fastened layer between described high temperature resistant packed layer and the second Ceramic silicon rubber fireproof layer.
The utility model structure is simple, long service life, and reliability is high, good insulating, is suitable for voltage range wide.The utility model comprises insulating sleeve and several cable core unit, by Combination Design such as built-in first Ceramic silicon rubber fireproof layer, the second Ceramic silicon rubber fireproof layer, watertight composition, insulating barrier and metal screen layers, can prevent cable under middle high-pressure environment, causing the phenomenon punctured because insulation property are low.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Protection range of the present utility model is not only confined to the statement of following content.
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: 1, cable core unit; 2, the first Ceramic silicon rubber fireproof layer; 3, insulating barrier; 4, watertight composition; 5, metal screen layer; 6, high temperature resistant packed layer; 7, the second Ceramic silicon rubber fireproof layer; 8, insulating sleeve; 9, insulate fastened layer.
Embodiment
Shown in Figure 1, ceramic fireproof cable, it comprises insulating sleeve 8 and several cable core unit 1; Described several cable core unit 1 is positioned at insulating sleeve 8; Coated first Ceramic silicon rubber fireproof layer 2 on described cable core unit 1; Coated insulation layer 3 on described first Ceramic silicon rubber fireproof layer 2; Coated watertight composition 4 on described insulating barrier 3; Clad metal screen 5 on described watertight composition 4; High temperature resistant packed layer 6 is provided with between the outer wall of described several cable core unit 1 and insulating sleeve 8 inwall; The second Ceramic silicon rubber fireproof layer 7 is provided with between described high temperature resistant packed layer 6 and insulating sleeve 8 inwall.
High temperature resistant packed layer 6 described in the utility model can adopt glass fiber winding arrangement.The utility model can be provided with the fastened layer 9 that insulate between described high temperature resistant packed layer 6 and the second Ceramic silicon rubber fireproof layer 7.
The utility model insulating sleeve 8, except insulation electrical, also has protection cable core unit to avoid the effect fractureed.First Ceramic silicon rubber fireproof layer and the second Ceramic silicon rubber fireproof layer mainly adopt the components such as silicon rubber, mica powder, mineral silicate, fire retardant, reinforcing agent.When cable is by fire, said components can sinter hardening and show as ceramic characteristic, thus provides protection for cable.The watertight composition that the utility model is arranged can play waterproof action to cable inside.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
