Abstract
The invention relates to a novel longitudinally waterproof flexible inorganic insulated fireproof cable. The cable is characterized in that the cable conductor consists of a plurality of stranded copper wires; each wire core is composed of a synthetic mica tape wrapping layer outside the cable conductor, and a glass fiber wrapping tape layer outside the synthetic mica tape wrapping layer; a binding agent is applied between the synthetic mica tape wrapping layer and the glass fiber wrapping tape layer; an inorganic fiber filler is filled in the space among a group of wire cores; the inorganic fiber filler is doped with water-blocking yarns, and is coated with a thermal-radiation prevention coating; a water-blocking wrapping tape wraps the inorganic fiber fillers; and the water-blocking wrapping tape is a copper sleeve with a galvanized layer outside the copper sleeve. The novel longitudinally waterproof flexible inorganic insulated fireproof cable has the advantage that the synthetic mica tape wrapping layer can enhance the insulation performance, and the glass fiber wrapping tape layer can enhance the force physical property so as to effectively prevent fire and improve the flexibility; the water-blocking tape and the water-blocking yarns can effective prevent longitudinal invasion of water; and the copper sleeve with the galvanized layer can effectively enhance the fire resistance and corrosion resistance.
Description
Technical field
The present invention relates to a kind of fireproof cable, relate in particular to the flexible inorganic insulation fireproof cable of a kind of novel longitudinal water proof type.
Background technology
At present, fireproof cable adopts organic material rubber, plastics etc. as insulating material usually, and when ignition of cable, insulating barrier burns totally, and the smog that is caused by the plastics burning simultaneously can cause " secondary disaster "; Traditional mineral insulated cable is with the cable of metal oxides such as magnesia powder as insulating material; It has excellent performance such as fire-resistant, explosion-proof, high temperature resistant, and the circuit that guarantees to catch fire is supplied power within a certain period of time, has improved the fireproofing of cable performance; But its complex process, cost is high.Factory length is also restricted simultaneously; The easy moisture absorption of magnesia powder, moisture content along cable vertically deeply causes the decline of insulating performance of cable after the moisture absorption, influences electric property.In addition, the cable bending property is relatively poor, installs and lays inconvenience, and the scope of application is restricted.
Summary of the invention
In order to overcome the deficiency in the existing fireproof cable technology, the present invention provides a kind of novel longitudinal waterproofing type inorganic insulation flexible fire-proof cable, and this flexible fire-proof cable is simple in structure, can prevent fires effectively, high temperature resistant, vertically block water, corrosion-resistant and pliability is high.
The technical solution adopted for the present invention to solve the technical problems is: its cable conductor is set up jointly by multiply metallic copper skein silk; Every core is made up of cable conductor outerwrap synthetic mica tape lapping layer, the wrapped belt of synthetic mica tape lapping layer outerwrap glass fiber; And scribble adhesive between the wrapped belt of synthetic mica tape lapping layer and glass fiber, fill the inorfil inserts between one group of core, the inorfil inserts is mixed with water blocking yarn; And scribble the thermal radiation resistant coating on the inorfil inserts; The inorfil inserts outerwrap twining package tape that blocks water, the twining package tape that blocks water is copper sheath outward, copper sheath is outward a zinc coat.
Between inorfil inserts and copper sheath, be provided with a wrapped reinforced layer.
Scribble the thermal radiation resistant coating on the described wrapped reinforced layer.
The present invention realizes like this that its purpose, conductor are adopted to press circular configuration, and this structure factory length is unrestricted, is convenient to processing, and electric cable accessories is simple, and is easy for installation; The multilayer synthetic mica tape lapping layer of conductor outerwrap has increased insulation property and fire resistance property, and product meets BS, IEC standard, under rated voltage, can bear 950 ℃, 3 hours burning test, and guarantees the normal power-up operation of circuit; The wrapped belt of glass fiber of synthetic mica tape lapping layer outerwrap has improved the insulation physical and mechanical properties; Copper sheath has the excellent sealing effect, stops the footpath of moisture content to go into to immerse; The outer zinc coat of copper sheath has increased the corrosion resistance of cable, in the more serious occasion of chemical corrosion, can play antiseptic effect.Block water twining package tape and water blocking yarn that cable is inner have at cable end under the situation of moisture content intrusion, expand rapidly, stop moisture content further deeply vertical, guarantee the electrical insulation properties of cable.
The invention has the beneficial effects as follows: because the synthetic mica tape lapping layer has increased insulation property, the wrapped belt of glass fiber has improved the power physical property, plays fire prevention and flexible purpose effectively; Waterstop and water blocking yarn can effectively stop vertical immersion of moisture content.Copper sheath is provided with zinc coat outward again and has strengthened fire resistance and corrosion resistance effectively, adopts embossing or embossing structure not according to the occasion different Cu sheath that uses.
