A kind of ethylene propylene rubber insulated type control cable, including master core, enter centered on master core and together with master core
If the twisted small core of carried interest for forming cable core of row.
The master core, small core include conductor, the ethylene propylene rubber insulated layer being extruded on the outside of conductor.
Interior separation layer is extruded with the outside of the cable core, the empty portions filling formed between the interior separation layer and cable core
There is low smoke and zero halogen oxygen barrier material.
It is provided with isolation lubricating layer on the outside of the interior separation layer, the outside of the isolation lubricating layer is according to from the inside to the outside successively
It is provided with proof copper-wire braided screen layer, sheath.
The isolation lubricating layer is included centered on the outer separation layer being distributed concentric with interior separation layer, the in addition axis of separation layer
The separator tube being uniformly and symmetrically distributed in the annular region formed in outer separation layer and interior separation layer, the outer separation layer with it is interior every
Empty portions are filled with lubricating grease in the annular region that absciss layer is formed.
Several are provided with equal intervals through proof copper-wire braided screen layer, sheath along axis direction on the outer separation layer
And the oil sealing plug coordinated with outer separation layer screw thread.
The oil sealing is provided with the sealing ring sealed beyond the Great Wall.
The separator tube is hollow rubber flexible pipe.
The interior separation layer, outer separation layer are that elastomeric material is made.
The beneficial effects of the invention are as follows：The present invention is reasonable in design, using the design of lubricating grease, can electric cable transporting,
The pliability of inside is improved during use, and the abrasion that the friction belt between internal part is come can be reduced, so as to electricity
Cable serves good protective effect, extends the service life of cable.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the internal structure schematic diagram of the present invention；
Fig. 2 is Fig. 1 A-A cross section structure diagrams.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, below it is right
The present invention is expanded on further.
As depicted in figs. 1 and 2, a kind of ethylene propylene rubber insulated type control cable, including master core, centered on master core simultaneously
If with carrying out the twisted small core of carried interest for forming cable core together with master core.
The master core, small core include conductor 1, are extruded in the ethylene propylene rubber insulated layer 2 in the outside of conductor 1.The present invention
The ethylene propylene rubber insulated layer 2 used, the insulating properties of entirety can be improved.
Interior separation layer 11, the empty portions formed between the interior separation layer 11 and cable core are extruded with the outside of the cable core
Filled with low smoke and zero halogen oxygen barrier material 10, so as to the degree of packing that boudoir is overall.
The outside of the interior separation layer 11 is provided with isolation lubricating layer, the outside of the isolation lubricating layer according to from the inside to the outside according to
It is secondary to be provided with proof copper-wire braided screen layer 6, sheath 7.
The isolation lubricating layer includes the outer separation layer 5 being distributed concentric with interior separation layer 11, the axis of separation layer 5 is in addition
Center is uniformly and symmetrically distributed the separator tube 4 in the annular region formed in outer separation layer 5 and interior separation layer 11, the outer isolation
Empty portions are filled with lubricating grease 3 in the annular region that layer 5 is formed with interior separation layer 11.The present invention can be using lubricating grease 3
