Abstract
The utility model discloses a kind of shielding compensating cable, comprise several conductor groups, each conductor group all has two conductors, conductor is coated with crosslinked polyetylene insulated layer and forms insulated wire cores, after insulated wire cores pair twist, outside is coated with lapping layer, sub-shield, several conductor groups wherein one join and surround annular and form cable core, cable core extrusion moulding is in ceramic silicon rubber protective layer, ceramic silicon rubber protective layer center is provided with foamed plastic core, ceramic silicon rubber protective layer is coated with aluminium-plastic tape lapping layer outward successively, total screen, low smoke halogen-free flame-retardant polyolefin external sheath layer.The utility model structural design is novel; by several conductor groups wherein one join and surround annular and form cable core; cable core extrusion moulding is in ceramic silicon rubber protective layer; overall weight is comparatively light; be convenient to install and lay; in addition, coordinate sub-shield, total isostructural design of screen to improve the stability of the overall signal transmission of cable.
Description
technical field:
The utility model relates to electric wire, relates in particular to a kind of shielding compensating cable.
background technology:
Conventional compensating cable, its insulation and sheath material are all polyvinyl chloride, are the materials that contains halogen, cannot meet the needs that those use in the environment of Halogen.
At present, also there is the defect that shielding properties is comparatively weak in traditional compensating cable, and compensating cable mostly is the some mutual stranded bunchys of single core insulation core and forms cable core, and practical ranges is relatively narrow, can not meet the need of market.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of shielding compensating cable, and structural design is novel, and compact overall structure is good, and overall weight is comparatively light, and shielding properties is remarkable, and the scope of application is extensive, long service life.
The technical solution of the utility model is as follows:
Shielding compensating cable, it is characterized in that: comprise several conductor groups, each conductor group all has two conductors, conductor is coated with crosslinked polyetylene insulated layer and forms insulated wire cores, after insulated wire cores pair twist, outside is coated with lapping layer, sub-shield, several conductor groups wherein one join and surround annular and form cable core, cable core extrusion moulding is in ceramic silicon rubber protective layer, ceramic silicon rubber protective layer center is provided with foamed plastic core, ceramic silicon rubber protective layer is coated with aluminium-plastic tape lapping layer outward successively, total screen, low smoke halogen-free flame-retardant polyolefin external sheath layer.
Described shielding compensating cable, is characterized in that: between the lapping layer of described conductor group and conductor, be provided with the fire-resistant packed layer that high-temperature fibre band and mineral wool rope form.
Described shielding compensating cable, is characterized in that: described conductor adopts alloy conductor.
The utility model has the advantages that:
The utility model structural design is novel; by several conductor groups wherein one join and surround annular and form cable core; cable core extrusion moulding is in ceramic silicon rubber protective layer; overall weight is comparatively light; be convenient to install and lay; in addition, coordinate sub-shield, total isostructural design of screen to improve the stability of the overall signal transmission of cable.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to accompanying drawing:
Shielding compensating cable, comprise several conductor groups, each conductor group all has two conductors 1, conductor 1 is coated with crosslinked polyetylene insulated layer 2 and forms insulated wire cores, after insulated wire cores pair twist, outside is coated with lapping layer 3, sub-shield 4, several conductor groups wherein one join and surround annular and form cable core, cable core extrusion moulding is in ceramic silicon rubber protective layer 5, ceramic silicon rubber protective layer 5 centers are provided with foamed plastic core 6, the outer aluminium-plastic tape lapping layer 7 that is coated with successively of ceramic silicon rubber protective layer 5, total screen 8, low smoke halogen-free flame-retardant polyolefin external sheath layer 9.
Between the lapping layer 3 of conductor group and conductor 1, be provided with the fire-resistant packed layer 10 that high-temperature fibre band and mineral wool rope form.
Conductor 1 adopts alloy conductor, and the pliability of conductor is good, and after stranding, bending property gets a promotion, and is convenient to transport and mounting and installation, has also reduced the cost of manufacture and mounting and installation.
