Abstract
The invention discloses a middle-voltage fire-resistant power cable with a voltage of 8.7/15 kV. The middle-voltage fire-resistant power cable comprises a cable core; the cable core is formed by twisting a plurality of insulation wire cores; each insulation wire core consists of a conductor, a conductor screening layer, a cross-linked polyethylene insulation layer, a semiconductor insulation screening layer and a copper belt metal screening layer; the conductor screening layer, the cross-linked polyethylene insulation layer, the semiconductor insulation screening layer and the copper belt metal screening layer are sequentially coated outside the conductor; inorganic water and fillers can be extruded in the cable core; and a first fire-resistant layer, a ceramic silicon rubber insulation layer, a second fire-resistant layer and a steel belt armoring layer are sequentially extruded outside the cable core; and a low smoke halogen-free fire-resistant outer sleeve is extruded outside the outermost layer. The middle-voltage fire-resistant power cable provided by the invention has the characteristics of simple manufacturing technique, reasonable price, long service life, high security property and the like.
Description
Technical field
The present invention relates to the electric wire field, specifically refer to a kind of middle pressure fireproof power cable.
Background technology
Existing fire-resisting cable technology is widely applied at low-voltage cable, electric pressure is 1kV and following, the construction of cable is for adopting fire-resistant isinglass belt to realize fire-resistant function, product is mainly used in needs fireproof building, public place etc. in the city, from distribution box or transformer with power delivery to each power unit.
Along with the development of skyscraper and the raising of fire-protection rating, and the reinforcement of people's awareness of safety, some building need to be transported to the top, building with the voltage of 15kV with the fire-resisting cable of 15kV.15kV voltage is higher, and traditional mica tape fire-resisting cable structure can't satisfy the designing requirement of electric field in the cable, is not suitable for fully, so only design the requirement that could satisfy simultaneously electrical property and fire resistance with the complete different structure of traditional fire-resisting cable.
Summary of the invention
Press fireproof power cable among the 8.7/15kV that the technical problem to be solved in the present invention provides that a kind of manufacturing process is simple, reasonable price, long service life, security performance are high.
A kind of middle pressure fireproof power cable of the present invention comprises cable core, and its cable core is to form by several insulated wire cores are stranded; The inorganic water of extruding and filling extrude the first flame-retardant layer, separator, the second flame-retardant layer, armour successively outside cable core in cable core, and outermost layer extrudes oversheath.
Described insulated wire cores is by conductor and is coated on successively conductor outer conductor shield, insulation, insulation screen, metal screen layer and consists of.
Described the first flame-retardant layer, the second flame-retardant layer are a kind of LSOH anti-flaming glass fibre belt.
Described separator is a kind of ceramic silicon rubber separation sleeve.
Described oversheath is a kind of LSOH anti-flaming material.
Beneficial effect of the present invention is:
Compared with prior art, higher grade of voltage cable of the present invention, and fully without fire-resistant isinglass belt, the construction of cable is simple, and selected material is easy to get, and is easy to process, and environment is not polluted; The inorganic hydration of extruding is filled, and can discharge large water gaging when meeting fire, and forms non-burn-through mineral-filled layer.The ceramic silicon rubber of extruding is met the shell that can form the non-burn-through ceramic of one deck after fire burns.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment:
As shown in Figure 1, a kind of middle pressure fireproof power cable of the present invention comprises cable core, and its cable core is to form by several insulated wire cores are stranded; Described insulated wire cores is by conductor 1 and is coated on successively the outer conductor shield 2 of conductor 1, crosslinked polyetylene insulated 3, semiconductive insulation screen 4, copper strips metal screen layer 5 and consists of; The inorganic water of extruding and filling 6 extrude the first flame-retardant layer 7, ceramic silicon rubber separator 8, the second flame-retardant layer 9, steel-tape armouring layer 10 successively outside cable core in cable core, and outermost layer extrudes LSOH anti-flaming oversheath 11.
The invention provides a kind of coaxial cable structure form and implementation method; the above only is preferred implementation method of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention; can also make some improvement, these improvement also should be considered as protection scope of the present invention.
