Description
Technical field
The present invention relates to a kind of cable, especially a kind of rated voltage 0.6 and 1KV silicon rubber insulations and high temperature resistant sheath are flat
Flat cable.
Background technology
Five development of the core plastic insulating power cable through nearly more than ten years, it has also become the important composition of 1kV plastic insulated cables
Part, and applied from key construction project and cities and towns skyscraper, develop into and largely used in low voltage power distribution network.
As the application environment of existing 5-core power cable is more and more extensive, the requirement to electromagnetic shielding and intensity is more next
Higher, existing cable is not often reached and its effect, and insulating cement by insulating rubber to carry out the effect of interference shielding
Piece easily receives the damage of external force, and existing solution is to increase by a protective metal shell in Exterior cable, is carried out by sheath
Effect in terms of electromagnetic shielding and raising intensity.But protective metal shell hardness is larger, it is not easy to recover after being not easy deformation and deformation, drops
The low recycling rate of waterused of cable.
The content of the invention
The present invention provides a kind of shield effectiveness that can improve cable, and can maintain its applicability rated voltage 0.6 and
1KV silicon rubber insulations and high temperature resistant sheath flat cable.
To achieve these goals, the present invention adopts the following technical scheme that：
The oval cable core formed including a cored wire and four subordinate lines being twisted around cored wire, described cored wire and subordinate line
Outside is provided with an insulating barrier, and a sheath is provided with outside insulating barrier, and described cored wire and subordinate line include inner conductor and located at conductors
The insulator on surface, it is characterised in that：Described sheath is to be socketed the silastic-layer with insulating barrier outer surface, outside described cable core
An aluminium foil and a drain wire are respectively equipped with, described aluminium foil 5 is connected with drain wire 6.
Preferably, described aluminium foil is one side clad aluminum foil.
Preferably, described one side clad aluminum foil metal level is located at inwall.
Preferably, described jacket inner wall is provided with non-hygroscopic nonmetallic tearing layer.
Preferably, one or more layers non-hygroscopic band is provided between described cable core and insulating barrier.
Preferably, the coincidence factor of described aluminium foil cladding is more than 25%.
Preferably, described aluminum foil thickness is more than or equal to 0.012mm.
Preferably, described drainage linear diameter is more than or equal to 0.5mm.
Preferably, described insulation diameter is 0.5mm.
Preferably, described insulation thickness is 0.2mm.
As a result of said structure, rated voltage 0.6 of the invention and 1KV silicon rubber insulations and high temperature resistant sheath are flat
Cable is covered on the outside of cable core by aluminium foil, and aluminium foil is connected with drain wire, and cable core is electromagnetically shielded by aluminium foil,
For insulating barrier, there is thickness of thin, the advantages of shield effectiveness is good, the screening ability of cable can be greatly improved, reduced
Interference, and using silastic-layer as sheath, silastic-layer is applied in combination with aluminium foil has the function that original protective metal shell,
And keep the pliability of cable.
