Abstract

The utility model discloses an energy-saving type flexible fireproof multi-core cable comprising a cable core. The cable core is formed by means of intertwisting several fan-shaped insulation wire cores. The fan-shaped insulation wire cores are composed of fan-shaped conductors and insulation layers wrapping the outside of the fan-shaped conductors. A synthetic flogopite tape wraps the cable core in a winding mode. A corrugated copper sheath longitudinally wraps the outside of the composite bronze mica tape. A low-smoke zero-halogen polyolefin outer sheath which is used for preventing oxidative deterioration caused by long-term contact of the corrugated copper sheath and air and which also serves as an oxygen barrier layer is arranged outside the corrugated copper sheath in an extruding mode. According to the energy-saving type flexible fireproof multi-core cable of the utility model, the round conductors of the energy-saving flexible fireproof multi-core cable are changed to be fan-shaped, so that the surface area is increased, the surface effect of current transmission is strengthened, and the cable can have large current-carrying capacity. When the cable is formed, complicated material filling operations are omitted, the production efficiency is improved, and the overall outer diameter of the cable is reduced by 5%-7%. Furthermore, materials required by the layers are decreased on the premise that structures of the layers are invariable, and resources are saved.

Description

A kind of energy-saving fire resistant flexible multicore cable
Technical field
The utility model relates to the electric wire field, specifically refers to a kind of energy-saving fire resistant flexible multicore cable.
Background technology
Along with fireproof cable plays an important role in modern Urban Architecture, as densely populated places such as high-rise civil building, office building, hotel, market, exhibition center, museum, library, hospital, gymnasium, airports, be widely used.
And existing fireproof cable is all often to form insulated wire cores at the wrapped mica tape in circular stranded conductor outside, phlogopite or muscovite, and then insulated wire cores is carried out to stranded formation cable core, owing to being circular stranded conductor, so there is space in the cable core after causing insulated wire cores stranded, filling also will be placed in the inside, space at cable core, not only increase cost, external diameter also can be very large; Because conductor assembly outer diameter is large, so it is also very big that the consumption of pricking the line copper sheath finally is set outside.Often ignored energy savings in production process, reduced and consume this major issue.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of not only flexible, ampacity is large, and reduces the whole cable external diameter, saved the energy, reduced the fire prevention multicore cable of cost.
A kind of energy-saving fire resistant flexible multicore cable described in the utility model, comprise cable core, wrapped synthetic gold mica tape outside cable core, and vertical wrapping line copper sheath outside synthetic gold mica tape, the cable core outermost layer extrudes the low-smoke halogen-free polyolefin oversheath; Described cable core is by some stranded the forming of fan-shaped insulated wire cores, and its fan-shaped insulated wire cores is by sector conductor and is extruded in the outer insulating barrier of sector conductor and forms.
Further improve, described sector conductor is by many stranded the forming of oxygen-free copper monofilament.
Further improve, described insulating barrier adopts synthetic phlogopite to tighten.
Further improve, described fan-shaped insulated wire cores is 3 cores, and its fan-shaped angle is 120 degree.
Further improve, described fan-shaped insulated wire cores is 4 cores, and its fan-shaped angle is 90 degree.
Further improve, described fan-shaped insulated wire cores is 5 cores again, and its fan-shaped angle is 72 degree.
The beneficial effects of the utility model are:
Compared with prior art, conductor described in the utility model is changed into fan-shaped by circle, causes surface area to increase, and has strengthened electric streamed skin effect, makes cable can carry larger ampacity.During stranding, saved loaded down with trivial details packing material, production efficiency has improved, whole cable reduced diameter 5%-7%, on each layer of structure under constant prerequisite because external diameter reduces, cause each layer of material requested also just to reduce, saved resource, reduced cost.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of energy-saving fire resistant flexible multicore cable described in the utility model, comprise cable core, described cable core is by some stranded the forming of fan-shaped insulated wire cores, and its fan-shaped insulated wire cores is by sector conductor 1 and is extruded in sector conductor 1 outer insulating barrier 2 and forms; Wrapped synthetic gold mica tape 3 outside cable core, at the outer vertical wrapping line copper sheath 4 of synthetic gold mica tape 3, in order to prevent that pricking the line sheath contacts and cause oxidation deterioration with air for a long time, thus in bundle line copper sheath 4 outsides, adopt fashion of extrusion to extrude one deck low-smoke halogen-free polyolefin oversheath 5, and double as oxygen barrier layer.
Sector conductor 1 described above is by many stranded the forming of oxygen-free copper monofilament.When fan-shaped insulated wire cores is three cores, its fan-shaped angle is 120 degree; When fan-shaped insulated wire cores is four-core, its fan-shaped angle is 90 degree; When fan-shaped insulated wire cores is five cores, its fan-shaped angle is 72 degree.
The concrete application approach of the utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
