Description
Technical field
The utility model is related to technical field of electric wires and cables, and in particular to a kind of electric wire.
Background technology
Architectural engineering cable is when being laid with, generally using direct burial or aerial, generally require passing through building, road and
Subject to damage place, thus bend and surface damage possibility it is larger, be susceptible to cable breakdown, damage the problems such as and cause
It can not use.
In addition, the currently known cable for architectural engineering, using halogen insulated with material layer, restrictive coating.Due to building
Engineering phenomenon cable cluster laying, once fire occurs, halogen generates a large amount of dense smokes, makes rescue work be difficult to carry out, personnel are past
Toward not being scorched to death not instead of immediately, due to by the smoked asphyxia of smog, causing personal life danger and " secondary hazards ".Build work
Journey is had attracted more and more attention from people with cable, and as an important development direction of line cable industry.
Utility model content
The purpose of the utility model is to provide a kind of long-life type architectural engineering cables, solve the above technical problem.
Following technical scheme may be used to realize in the technical issues of the utility model is solved：
Long-life type architectural engineering cable, including conductor thread core, be equipped with successively outside the conductor thread core ceramic silastic-layer,
Low-smoke halogen-free polyolefin layer, nylon outer sheath layer.
The ceramic silastic-layer of the utility model has elasticity well, can guarantee bending and drawing in construction projects
It stretches.Low-smoke halogen-free polyolefin layer, not will produce a large amount of dense smoke and toxic gas when fire occurs, and burning is relatively more tired
Difficulty has good flame retardant efficiency.Nylon outer sheath layer has wear-resisting, oil resistant, chemical resistance and heat resistance outstanding feature.Cause
This utility model can be used in architectural engineering well by above-mentioned several layers of combinations, not only can be to avoid generation fire
When secondary hazards, especially in architectural engineering, the damage of cable is avoided well, the utility model can reach 70 years
Service life.
The ceramics silastic-layer is using refractory protection made of Ceramic silicon rubber material.The ceramics of the utility model
Refractory protection made of SiClx rubber material at normal temperatures it have the good fundamental characteristics of silicon rubber elastic, have it is nontoxic,
Tasteless, high-low temperature resistant, resistance to ozone aging, weatherable, excellent electrical insulation capability, it is good also to have common high temperature silicone rubber
Processing performance, can keep flexible cable state to 200 degree above freezing or so in 40 degrees below zero.Flame invade, temperature up to 300 degree with
When upper, the sponge ceramic body of hardness can be converted to by original soft condition, generate hole after being hardened inside refractory protection, have
Conducive to heat preservation, such sponge ceramic body has the function of significant fire resisting and barrier high temperature, to be effectively protected conductor thread core
Internal structure do not occur machinery change and electrical property variation.
The nylon outer sheath layer is using external sheath layer made of Nylon-1010.The most prominent advantage of nylon 1010 is
When being stretched to 3-6%, elastic restoration ratio is amenable to up to ten thousand foldings and scratches and not broken up to 100%.Therefore the utility model
Nylon outer sheath layer is not only light-weight, environmentally friendly, self lubricity is good, also has surface strength outstanding height, does not allow easy damaged,
Advantage with long service life.
The conductor thread core uses stranded conductor parallel or the manufactured conductor thread core that is twisted together.Since the utility model makes
With the limitation of occasion, movement and corner frequency are high, therefore conductor thread core avoids using sub-thread, but use multiply form, into
One step ensure that the utility model still securely and reliably uses, and increases its service life in mobile and bending cable.
Advantageous effect：Due to using the technology described above, the utility model also had fireproof wear-resisting etc. up to 70 year service life
Significant properties.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the utility model.
Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under
Face, which combines to be specifically illustrating, is expanded on further the utility model.
Referring to Fig.1, long-life type architectural engineering cable, including conductor thread core 1, conductor thread core 1 are equipped with ceramic silicon successively outside
Rubber layer 2, low-smoke halogen-free polyolefin layer 3, nylon outer sheath layer 4.Conductor thread core 1 uses stranded conductor parallel or the system of being twisted together
At conductor thread core 1.Ceramic silastic-layer 2 is using refractory protection made of Ceramic silicon rubber material.Nylon outer sheath layer 4
Using external sheath layer made of Nylon-1010.
The ceramic silastic-layer 2 of the utility model has elasticity well, can guarantee bending and drawing in construction projects
It stretches.Low-smoke halogen-free polyolefin layer 3, not will produce a large amount of dense smoke and toxic gas when fire occurs, and burning is relatively more tired
Difficulty has good flame retardant efficiency.Nylon outer sheath layer 4 has wear-resisting, oil resistant, chemical resistance and heat resistance outstanding feature.
Therefore the utility model can be used in architectural engineering well by above-mentioned several layers of combinations, not only can be fiery to avoid occurring
Secondary hazards when calamity, especially in architectural engineering, the damage of cable is avoided well, the utility model can reach 70 years
Service life.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
