Abstract
The utility model discloses a control cable, belonging to cable technical field. The utility model is characterized in that the cable conductor adopts a double-layer insulated structure; the inner insulated layer of the conductor surface adopts crosslinked polyethylene; the outer insulated layer adopts non-halogen low-smoke polyolefin; a filling layer, a non-halogen low-smoke wrapping belt, a copper strip wrapping, a non-halogen low-smoke wrapping belt and a non-halogen polyolefin outer sheath. The utility model has the advantages of low smoke density, good flame retardation, long service life and good impact resistance performance, according to the performance requirements of control cable completely, suitable for the power supply cable of power supply system with six hundred and one thousand V voltage rating or less or the wire connection of electrical equipment; the utility model is mainly used in power station, high-rise building, subway, ships, petrochemical fields; in addition, the utility model has wide usage and better social benefits and economic benefits.
Description
Technical field
The utility model relates to a kind of control cable structure, belongs to the cable new technical field.
Background technology
China's wires and cables industry will be by 10%～15% speed increment preceding 10 years of 21 century, and in the therefore following period, electric wire will welcome the animated period of a demand.The wires and cables industry of China has formed suitable scale through high speed development in a few years, but because production capacity greater than demand, easy situation occurs, and technology content is not very high, still is difficult to satisfy for some specific demands.Based on this situation, just show one's talent in special cable market, attracting increasing people to pay close attention to.Along with people to the attention of safety, environmental protection and the influence of other various factorss, the cable of other special applications such as shipboard cable, fire safety cable, rolling stock cable and used in nuclear power station cable more and more is subjected to people's welcome.These have in light weight, characteristics such as volume is little, low cigarette, Halogen, fire prevention with thermoplastic insulation or crosslinked polyetylene insulated special cable, thus installation, environmental protection easily, and fire safety.And China's infrastructure and engineering construction project are numerous, and there is huge latency development space especially in its cable market.According to statistics, control cable market the market demand in 2002 of China is about 3,000,000 dollars, is about 5,000,000 dollars in 2003.The a plurality of great international events that are about to hold in China (as the Asian Games in the 2008 Beijing Olympic Games and Shanghai World's Fair in 2010, Guangzhou etc.) all will increase numerous construction projects that require high-quality and high safety, further increased the market demand thus to special cables such as control cable.
The utility model content
Technical problem to be solved in the utility model is to overcome the defective that current general control cable exists, provide a kind of have high pressure resistant, smoke density is low, fire resistance good, the life-span is long, anti-seismic performance is excellent, mechanical strength height, the control cable that moisture resistance is good.
The purpose of this utility model is achieved in that a kind of control cable, comprise cable core, lapping layer and oversheath, the conductor in the middle of described cable core comprises and the insulating barrier of conductive surface, lapping layer and oversheath are wrapped successively outside cable core, it is characterized in that: the insulating barrier of described cable core is a double-decker.
The double hyer insulation layer is respectively crosslinked polyethylene inner insulating layer and low smoke, zero halogen polyolefin external insulation layer, and described conductor is a copper conductor.
The above-mentioned lapping layer of stating has three layers, is respectively low smoke, zero halogen twining package tape, copper strips twining package tape, low smoke, zero halogen twining package tape from inside to outside.
Above-mentioned oversheath is the halogen-free polyolefin oversheath.
The utility model is rational in infrastructure simple, and the manufacturing is easy, cost is low.Cable has stronger electrical property, insulation property, fire resistance; Construction of cable compactness, rounding can satisfy the performance requirement of the control cable of modernization project in building fully.Be mainly used in the power station, also can be used for fields such as skyscraper, subway, boats and ships, petrochemical industry, purposes is more extensive.Because it has advantages such as the HCL burst size is low, insulation resistance is high, life of product is long, when burning, do not produce toxic gas and smog, help carrying out smoothly of rescue and withdrawing of disaster affected people, simultaneously instrument, equipment are not produced corrosion, be applicable to the above-mentioned occasion high fully safety requirements.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, conductor 2, interior insulation 3, external insulation 4, filling 5, low smoke, zero halogen twining package tape 6, copper strips twining package tape 7, low smoke, zero halogen twining package tape 8, halogen-free polyolefin oversheath
Embodiment
As shown in Figure 1, extrude crosslinked polyetylene insulated layer 2 and low smoke, zero halogen polyolefin insulation layer 3 formation cable cores successively on the surface of copper stranded conductor 1, the outside is provided with three layers of lapping layer, fill with inserts 4 between lapping layer and cable core, three layers of lapping layer from inside to outside are respectively low smoke, zero halogen twining package tapes 5, copper strips twining package tape 6 and low smoke, zero halogen twining package tape 7 extrude the halogen-free polyolefin oversheath at last.
Claims (4)
1. a control cable comprises cable core, lapping layer and oversheath, the conductor in the middle of described cable core comprises and the insulating barrier of conductive surface, and lapping layer and oversheath are wrapped successively outside cable core, it is characterized in that: the insulating barrier of described cable core is a double-decker.
2. control cable according to claim 1 is characterized in that described double hyer insulation layer is respectively crosslinked polyethylene inner insulating layer and low smoke, zero halogen polyolefin external insulation layer.
