Abstract
The utility model provides a power cable for providing power supply for communication equipment, aiming at the current situations of the prior art in order to solve the technical problem. The power cable comprises metal lead wires 1, flame-retardant insulating layers 2 and shield covers 3. The flame-retardant insulating layers 2 are wrapped outside the metal lead wires 1, the shield covers 3 are arranged outside the flame-retardant insulating layers 2, flame-retardant jackets 4 are arranged at the outer sides of the shield covers 3, and the two lead wires 1 which are wrapped with the flame-retardant insulating layers 2 are sheathed at the shield covers 3. The sections of the metal lead wires 1 are rectangular. The outlines of the sections of the flame-retardant jackets 4 are rectangular and in the shapes of chamfer angles. Flame-retardant and insulation materials in the power cable adopt halogen-free low-smoke insulation materials, such as polyolefin. The original round sections of the lead wires are changed into rectangular sections, and then two rectangular insulating wire cores are merged into one cable core, so that the outer diameter of the power cable is reduced by 15% compared with the round cable with the same specifications; moreover, the insulation and jacket materials are saved by 10%, and one working procedure is reduced as well.
Description
Technical field
The utility model relates to the cable technology field, is specially a kind of power cable that is applicable in the communication apparatus and supply of electric power is provided for equipment
Background technology
Show according to authoritative institution investigation, much build breaking out of fire and all be the electrical fire that reasons such as causing spontaneous combustion owing to cable is aging short out causes.And the most serious disaster is drawing out of intensity of a fire court of a feudal ruler cable line after fire takes place.How to reduce potential safety hazard, improve the fail safe of system, become the primary safety problem of a lot of new buildings.After introducing Structured Cabling System, the cable total amount that is installed in the commercial building has had very big growth.Usually cable by the colligation bunchy and be installed in suspended ceiling and sandwich boards for construction between the space in, or be installed under the floor of raising.This just requires to pay special attention to the performance of cable, not only is their transmission characteristic, also is to prevent potential fire.Necessary improvement has all been done by numerous in this respect manufacturers, such as in order to adopt the fire retardant insulating sheath on the fire prevention sheath, still because technology causes the increase of cable production cost, in addition because the restriction of profile is also bigger to occupying of space.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of power cable that is applicable in the communication apparatus and supply of electric power is provided for equipment at above-mentioned prior art present situation, when guaranteeing reliable conduction, embody fire-proof insulation, and cost is lower, the space hold rate is low.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of power cable that is applicable in the communication apparatus and supply of electric power is provided for equipment, comprise plain conductor (1), wrap up in and invest the outer flame retardant insulation (2) of plain conductor (1) and be arranged at flame retardant insulation (2) housing (3) outward, housing (3) arranged outside has fire retardant jacket (4), and described housing (3) is arranged with two leads (1) of wrapping up in attached flame retardant insulation (2).
The cross section of described plain conductor (1) is a rectangle.
Described fire retardant jacket (4) cross section outline is rectangle and chamfering.
The beneficial effects of the utility model are: change original cross section into rectangle for circular lead, making the doubling of two rectangle insulated wire cores then is a cable core, and the external diameter of the round cable of comparable same specification reduces by 15%. insulation and sheath material saves 10%.And reduced one procedure.This cable is assemblied in the communication apparatus, if use normally used round cable, just have bigger physical dimension, will increase the overall size and the weight of entire equipment like this, thereby increased manufacturing and cost of transportation, adopted low smoke, zero halogen insulation and sheath material, under the cable fire state, seldom discharged smog, poison gas and corrosive gas, the fail safe that can effectively improve communication system.
Description of drawings
Fig. 1, a kind of power cable cross section structure schematic diagram that is applicable in the communication apparatus and supply of electric power is provided for equipment.
Embodiment
Shown in Figure 1, a kind of power cable that is applicable in the communication apparatus and supply of electric power is provided for equipment, comprise plain conductor 1, wrap up in and invest the outer flame retardant insulation 2 of plain conductor 1 and be arranged at the outer housing 3 of flame retardant insulation 2, housing 3 arranged outside have fire retardant jacket 4, and described housing 3 is arranged with two leads 1 of wrapping up in attached combustion insulating barrier 2.The cross section of described plain conductor 1 is a rectangle.Described fire retardant jacket 4 cross section outlines are rectangle and chamfering.Fire-retardant and insulating material employing low smoke, zero halogen insulating material in the utility model, such as: polyolefin.
Claims (3)
1, a kind of power cable that is applicable in the communication apparatus and supply of electric power is provided for equipment, comprise plain conductor (1), wrap up in and invest the outer flame retardant insulation (2) of plain conductor (1) and be arranged at flame retardant insulation (2) housing (3) outward, housing (3) arranged outside has fire retardant jacket (4), it is characterized in that: described housing (3) is arranged with two leads (1) of wrapping up in attached combustion insulating barrier (2).
2, a kind of be applicable in the communication apparatus and for equipment provides the power cable of supply of electric power, it is characterized in that: the cross section of described plain conductor (1) is a rectangle according to claim 1.
3 according to management expectancy 1 or 2 described a kind of are applicable in the communication apparatus and for equipment provides the power cable of supply of electric power, it is characterized in that: described fire retardant jacket (4) cross section outline is rectangle and chamfering.
