Abstract
The utility model discloses a kind of PVC-C cable sleeves, including PVC-C tube body, the fiber glass reinforced polypropylene around PVC-C tube wall setting and nylon composite layer, the insulating layer for surrounding the fiber glass reinforced polypropylene and the setting of nylon composite layer, around insulating layer setting metal layer, the thermal insulation layer, the wearing layer for surrounding thermal insulation layer setting, the conductive coating for being set to the potsherd of the PVC-C inboard wall of tube body and being located between the PVC-C tube body and the potsherd that are arranged around the metal layer.Compared with the relevant technologies, the PVC-C cable sleeve intensity is big, and wearability is good and easy for installation.
Description
Technical field
The utility model relates to a kind of PVC-C cable sleeves.
Background technique
For chliorinated polyvinyl chloride (PVC-C) power cable protecting pipe using chlorinated polyvinyl chloride resin as primary raw material, addition must
The auxiliary agent wanted, the improved power cable protecting pipe with specific physical performance of one kind through extrusion molding.Cable is buried
It in laid processes, is required to set protection pipe in cable jacket, to play the role of protecting cable.It has at present by chlorinated polyvinyl chloride second
Alkene and thermoplastic material are nested together the composite cable conduit to be formed, and also have thermosetting plastics and thermoplastic material
By intermediate adhesive layer, the composite cable conduit that it is bonded together into indirectly.However, due to tube body receipts inside and outside multiple tube
Contracting difference, since intensity is bad, and wearability is inadequate, be easy to cause the loss of tubing, and service life is low.
Therefore, it is necessary to a kind of novel PVC-C cable sleeve be provided, to overcome defect in the prior art.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of PVC-C cable sleeve, the PVC-C cable sleeve is strong
Degree is big, and wearability is good and easy for installation.
The technical solution of utility model is as follows:
A kind of PVC-C cable sleeve gathers including PVC-C tube body, around the fiberglass reinforced of PVC-C tube wall setting
Propylene and nylon composite layer, the insulating layer of the circular fiber glass reinforced polypropylene and the setting of nylon composite layer, the circular insulation
Layer setting metal layer, the thermal insulation layer around metal layer setting, the wearing layer around thermal insulation layer setting, be set to it is described
The potsherd of PVC-C inboard wall of tube body and the conductive coating being located between the PVC-C tube body and the potsherd.
Further, the conductive coating with a thickness of 20-25 μm.
Further, the potsherd with a thickness of 2-3mm.
Further, the metal layer is galvanized steel wire netting.
Further, the insulating layer with a thickness of 3-4mm.
Further, the length of the PVC-C cable sleeve is 6-8m.
The utility model has the advantages that
The PVC-C cable sleeve of the utility model improves tubing by using fiber glass reinforced polypropylene and nylon composite layer
Tensile strength and impact flexibility；Inner wall smooth is made using potsherd, reduces frictional force, reduces threading resistance；It uses simultaneously
Conductive coating can effective electromagnetic wave absorption, prevent tubing from generating heat.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of PVC-C cable sleeve.
Specific embodiment
The utility model is described in further details below with reference to the drawings and specific embodiments:
Embodiment 1: such as Fig. 1, a kind of PVC-C cable sleeve 100, including PVC-C tube body 1, outside the PVC-C tube body
What fiber glass reinforced polypropylene and nylon composite layer 2, the circular fiber glass reinforced polypropylene and the nylon composite layer 2 that wall is arranged were arranged
Insulating layer 3 metal layer 4, the thermal insulation layer 5 for surrounding the metal layer 4 setting is arranged around the insulating layer 3, around described heat-insulated
The wearing layer 6 of 5 setting of layer, be set to the potsherd 7 of 1 inner wall of PVC-C tube body and be located in the PVC-C tube body 1 with
Conductive coating 8 between the potsherd 7.
The conductive coating 8 with a thickness of 20-25 μm.The conductive coating is used for the electromagnetic wave that absorbs, conducts and decay, from
And play the role of shielding electromagnetic interference.A coating 8 of leading is using the inner wall of the metal spraying after hot melt to PVC-C tube body
Form one layer of pure metal sedimentary.
The potsherd 7 with a thickness of 2-3mm.The potsherd is for reducing friction, and resistance is smaller when installing cable, no
Cable sheath can be damaged.
The wearing layer 6 uses abrasive rubber.
The thermal insulation layer 5 uses rock wool heat-preservation felt, and rock wool heat-preservation felt has excellent thermal and insulating performance, and construct and
Installation is convenient, energy-saving effect is significant.
The metal layer 4 uses zinc-coated wire stratum reticulare.
The insulating layer 3 uses synthetic resin, with a thickness of 3-4mm.
The fiber glass reinforced polypropylene and nylon composite layer 2 can be improved the mechanical property of tubing, and hot property is mentioned
Height has good creep resistance etc..
The length of the PVC-C cable sleeve 100 is 6-8m.
The PVC-C cable sleeve of the utility model improves tubing by using fiber glass reinforced polypropylene and nylon composite layer
Tensile strength and impact flexibility；Inner wall smooth is made using potsherd, reduces frictional force, reduces threading resistance；It uses simultaneously
Conductive coating can effective electromagnetic wave absorption, prevent tubing from generating heat.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
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.
