Description

A kind of stretch-proof shield type mineral insulated cable
Technical field
This utility model relates to field of cables, particularly relates to a kind of stretch-proof shield type mineral insulated cable.
Background technology
At present, development along with science and technology, the fields such as industry and machinery are all at rapid advances, the usage amount of cable is greatly increased the most therewith, cable is widely used in controlling in the technology manufacture fields such as installation, connection equipment and handling cable, particularity because of these fields, thus cable is had higher requirement, but existing cable is because its fabrication design is unreasonable or the problem of material selection, during the use of cable, it is easy to that the situation that cable cover(ing) is worn occurs, causes cable internal structure to spill, bring a lot of inconvenience to the use of people.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of stretch-proof shield type mineral insulated cable.
This utility model takes techniques below scheme to realize: a kind of stretch-proof shield type mineral insulated cable, it includes cable body, described cable body includes conductor, mineral insulation layer, oxygen barrier layer and oversheath, and described cable body is internally provided with many conductors;One layer of enhancement Layer of described conductor outer wrapping;Described enhancement Layer and conductor collectively form cable core;Described cable body is internally provided with many cable cores;One layer of mineral insulation layer is set outside described cable core;One layer of fire-resistant expanding layer of mineral is extruded outside described mineral insulation layer;One layer of oxygen barrier layer is extruded outside the fire-resistant expanding layer of described mineral;One layer of lock armo layer is extruded outside described oxygen barrier layer;One layer of oversheath is extruded outside described lock armo layer.
Above-mentioned a kind of stretch-proof shield type mineral insulated cable, between described mineral insulation layer and cable core, gap portion is provided with packed layer.
Above-mentioned a kind of stretch-proof shield type mineral insulated cable, described mineral insulation layer uses mica material to make.
Above-mentioned a kind of stretch-proof shield type mineral insulated cable, described lock armo layer uses aluminum alloy strip interlocking to be prepared from.
Above-mentioned a kind of stretch-proof shield type mineral insulated cable, described oversheath uses polyurethane material to make.
Above-mentioned a kind of stretch-proof shield type mineral insulated cable, is surrounded with many elastic adhesive tapes inside the fire-resistant expanding layer of described mineral.
This utility model has the advantages that this utility model has reasonable in design, advantages of good shielding performance and the advantage such as easy to use in sum, described oversheath uses polyurethane material to make, so that cable body has the advantages such as good insulating properties, Inverter fed motor and arc resistance, in the case of temperature and frequency change, the electrical insulation capability of cable body can keep stable.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation;
Wherein: 1, cable body;2, conductor;3, enhancement Layer;4, packed layer;5, mineral insulation layer;6, the fire-resistant expanding layer of mineral;7, elastic adhesive tape;8, oxygen barrier layer;9, lock armo layer;10, oversheath.
Detailed description of the invention
As it is shown in figure 1, a kind of stretch-proof shield type mineral insulated cable, it includes that cable body 1, described cable body 1 include that conductor 2, mineral insulation layer 5, oxygen barrier layer 8 and oversheath 10, described cable body 1 are internally provided with many conductors 2;Described one layer of enhancement Layer 3 of conductor 2 outer wrapping;Described enhancement Layer 3 and conductor 2 collectively form cable core;Described cable body 1 is internally provided with many cable cores;One layer of mineral insulation layer 5 is set outside described cable core;One layer of fire-resistant expanding layer of mineral 6 is extruded outside described mineral insulation layer 5;One layer of oxygen barrier layer 8 is extruded outside the fire-resistant expanding layer of described mineral 6;One layer of lock armo layer 9 is extruded outside described oxygen barrier layer 8;One layer of oversheath 10 is extruded outside described lock armo layer 9.
Described mineral insulation layer 5 uses mica material to make, so that cable has, fire protecting performance is superior and operating temperature advantages of higher, makes cable body 1 internal structure the compactest, improves the service life of cable body 1;The fire-resistant expanding layer of described mineral 6 can form duricrust after meeting fire, forms the thermal resistance material of many spaces and high-foaming, has the anticollision performance of excellence;Described elastic adhesive tape 7 substantially increases the impact resistance of cable body 1, it is possible to buffering cable body 1 pressure experienced in time;Described oxygen barrier layer 8 can completely cut off the oxygen within cable body 1, it is hereby achieved that preferably flameproof effect;Described lock armo layer 9 uses aluminum alloy strip interlocking to be prepared from, and can effectively strengthen anticorrosive property and the water resistance of cable body 1, increase the bending radius of cable, also mitigate the weight of cable body 1 simultaneously;Described oversheath 10 uses polyurethane material to make, so that cable body 1 has the advantages such as good insulating properties, Inverter fed motor and arc resistance, in the case of temperature and frequency change, the electrical insulation capability of cable body 1 can keep stable.
The above is embodiment of the present utility model, therefore all equivalence changes done according to structure, feature and the principle described in this utility model application range or modification, all it is included in this utility model patent claim.
