Abstract
The utility model particularly relates to a novel flame resistant cable, including many cable cores, many cable cores are become a circular cross section by the mica tape compact winding, are being full of the filler material between mica tape and the duo gen cable core, the filler material is fire -retardant gasket for packing, and this circular cross section has still set gradually insulating layer, flame retardant coating, inoxidizing coating outward, the inoxidizing coating has inner sheath, armor, oversheath to constitute. The utility model provides a pair of novel flame resistant cable, change the inside filler material of this cable into fire -retardant gasket for packing, the refractiveness of cable has been improved, adopt the mica tape to wrap up the cable core, the refractiveness of cable is ensured to the fire resistance that utilizes mica tape self, and the mica tape that adopts comprises mica paper and reinforced materials, intensity and the electrical property of mica sinter layer are improved through reinforced materials, and but the fire -retardant fire -resistant silicon rubber combined material of fire -resistant adoption porcelainization makes, it can decompose the temperature of absorbing the heat and reducing the cable when high temperature, thereby provide the refractiveness of cable.
Description
Technical field
The utility model relates to field of cable technology, particularly relates to a kind of novel flame resistant cable.
Background technology
Along with the development of Chinese national economy, the demand of people to electric power increases year by year, cause the continuous quickening of Construction of Intercity Network transformation paces, the electric utility of China is obtained and develops fast, and then promoted the flourish of whole wires and cables industry.The Cultivar development of current cable is diversified development trend,
All trades and professions are also just more and more higher to the quality requirement of cable.At cable laying close quarterses such as skyscraper, postal and telecommunication entities, boats and ships, cable initiation fire will affect the normal life of industrial expansion and the people, and causes and remember great economic loss, and thus the demand of fire-resisting cable grows to even greater heights.Fire-resisting cable refers under certain flame temperature burning condition, and cable can normal transmission within a certain period of time, guarantees the normal operation of fire-fighting first-aid apparatus.
Utility model content
In view of the above, the purpose of this utility model is to provide a kind of novel flame resistant cable, solves that prior art is easily mechanically damaged cable, the problem of ageing of insulation.
A kind of novel flame resistant cable, comprise many cable cores, described cable core is disposed with conductor, internal shield, insulating barrier, outer shielding layer from inside to outside at cental axial position, wherein said insulating barrier adopts cross-linking polyethylene materials to make, many cable cores are closely wound in a circular cross-section by mica tape simultaneously, and packing material abrim between mica tape and Duo Gen cable core, described packing material is flame resistant filler rope, this circular cross-section is also disposed with thermal insulation layer, flame retardant coating, overcoat outward, and described overcoat has inner sheath, armour, oversheath to form.
A kind of novel flame resistant cable that the utility model provides, preferably, described flame retardant coating is for making by porcelain flame-retardant silicon rubber composite material.
A kind of novel flame resistant cable that the utility model provides, preferably, described mica tape is made up of mica paper and reinforcing material, and also arranges bonding coat between mica paper and reinforcing material.
