Description
Technical field
The utility model relates to XETFE insulated cable, specifically the special-shaped XETFE thinwalled insulation in a kind of high strength heavy in section cable.
Background technology
Along with the fast development of China's Aero-Space cause, space exploration scope constantly expands, Science Research Project going deep into gradually, Aero-Space are all had higher requirement to the own wt of airborne equipment, the bearing capacity of fuel and effective usage space, cable is as the key components of airborne equipment electric power transfer, at device interior, there is larger proportion and space occupancy, therefore, the mechanical performance of the external diameter reducing cable, the weight reducing cable, enhancing cable is the development need of current fluoroplastics thinwalled insulation cable.
In the prior art, the external diameter of extrusion type fluoro-containing plastic thinwalled insulation electric wire reduce and weight saving and mechanical performance increase mainly by reducing the measures such as the raw material of the thickness of insulation/restrictive coating, the external diameter of compressed conductor and employing high strength.Along with the introduction of external advanced material, insulation/restrictive coating the thickness of electric wire is compressed to the limit, then the structure of the insulation/sheath of cable changes to the type of thinner strip lap, but for the field of employment that some is special, as damp and hot in height, big current, many electric arcs etc., wrapped type structure should not use again; And compressed conductor external diameter is also there is certain limited range, excess compression will reduce the net sectional area of cable, reduces the bending property of product; Meanwhile, by the restriction that cable electricity function index requires, raw-material selection range is also subject to certain restrictions.
Summary of the invention
The purpose of this utility model is to solve the problems of the technologies described above, and provides a kind of high strength heavy in section special-shaped XETFE thinwalled insulation cable.This insulated cable is while meeting custom power transmission demand, in physical dimension and mechanical properties, the basis of fluoroplastics thinwalled insulation cable is optimized lifting again, greatly reduce the weight of product, installing space, enhance the mechanical performance of axial, the diametral tensile strength of cable.
Realizing the technical solution of the utility model is: a kind of high strength heavy in section special-shaped XETFE thinwalled insulation cable, comprises heavy in section allotype insulation conductor wire core, strengthening core, screen and oversheath; It is characterized in that: described heavy in section allotype insulation conductor wire core comprises three groups and above special-shaped conductor wire core; The many nickel plating copper-alloy stranded conductors that described special-shaped conductor wire core wraps up XETFE double-layer thin wall insulating barrier by top layer form; Described three groups and above special-shaped conductor wire core adopt the composition heavy in section allotype insulation conductor wire core that is intertwined of concentric stranding even structure; Described strengthening core is filled in the stranded space of cable core; Described screen is woven by nickel-clad copper alloy wire to form; Described oversheath melt extrudes by XETFE the outermost layer being coated on cable.
Many nickel plating copper-alloy stranded conductor groups of described top layer parcel XETFE double-layer thin wall insulating barrier are the abnormity through fan-shaped or trapezoidal mold pressing after concentric stranding, and the insulation of XETFE double-layer thin wall is by melt extruding, and is coated on special-shaped conductor wire core top layer.
Described XETFE double-layer thin wall insulating barrier and XETFE oversheath all have passed the radiation of the high-power electron beam of doses.
Non-metal N OMEX strengthening core is filled in the stranded space of described cable core.
The beneficial effects of the utility model are:
1, by the cable core that the insulated conductive wires core of Special-shaped moulded forms, effectively decrease the space between the circular cable core of traditional rule, reduce total external diameter of cable and the use amount of shielding material and sheath material.
2, by the radiation of high-power electron beam, the mechanical strength of insulating barrier and restrictive coating, temperature resistant grade and chemical stability is greatly improved.
3, the filling of NOMEX strengthening core, further enhances the axial tensile strength of cable, makes the cable core more rounding type of cable simultaneously, and the oversheath thickness of feed layer extruded is also evenly consistent, and the radial anti-tensile of cable also can significantly be strengthened by force.
4, compared with prior art the utility model to have axial-radial tensile strength superior, installing space takies the features such as little, weight is lighter, cost performance is higher, environmental suitability is strong, radiation hardness, performance safety are reliable.
