SUMMERY OF THE UTILITY MODEL

The utility model discloses technical scheme is too single technical problem to prior art solution, provides a copper core plastic control cable is showing and is being different from prior art's solution to propose in solving above-mentioned background art because often comparatively moist and cold in the tunnel, control cable lays for a long time and uses, very easily receives the erosion of moisture, low temperature, and influences the problem of control cable signal transmission stability.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a copper core plastic control cable, includes the sinle silk, the sinle silk is equipped with the thickening shielding layer that is used for shielding external signal of telecommunication interference outward, and has filled the filling layer between thickening shielding layer and the sinle silk to thickening shielding layer outer wall cladding has the waterproof layer, waterproof layer outer wall cladding has the silica gel cavity layer that is used for isolated temperature, and silica gel cavity layer outer wall cladding has the surrounding layer.

Further, the wire core comprises a conducting wire made of a copper wire and an insulating layer coated on the outer side of the conducting wire.

Furthermore, the thickened shielding layer is composed of an aluminum-plastic composite belt, the thickness of the thickened shielding layer is larger than that of the insulating layer, and the waterproof layer is composed of a copper-plastic composite belt.

Furthermore, the filling layer is made of mica materials, the silica gel cavity layer is made of silica gel materials, and cavities containing air are densely arranged in the silica gel cavity layer.

Furthermore, the outer cladding comprises a sheath made of polyvinyl chloride material, an anticorrosive layer coated on the outer wall of the sheath and made of epoxy resin material, and reinforcing ribs arranged inside the sheath.

Compared with the prior art, the beneficial effects of the utility model are that: this copper core plastic control cable, this cable is equipped with the surrounding layer of epoxy resin material through the outer wall and plays waterproof certain waterproof and anticorrosive effect, avoid the cable to use for a long time in the tunnel by humid gas erosion, and the setting up of the internal strengthening rib of surrounding layer has reduced the cable and under receiving the exogenic action, excessively buckle and the condition of harm takes place, air cavity through the internal intensive setting of silica gel cavity, one then can play certain buffering and resistant effect of buckling, two then because the air thermal conductivity of not circulating is relatively poor, thereby avoided the influence of external cold gas to inside sinle silk, the cable weight has also been reduced, be convenient for carry and use, three then intracavity air also can improve the insulating properties of cable, thereby the stability of signal transmission in dark moist tunnel of control cable has been promoted.

Through the setting of the waterproof layer that the compound area of copper plastic constitutes, when further having strengthened the ability of the dampproofing moisture erosion of cable again, also possess certain external signal of telecommunication interference's of shielding nature, the thickening shielding layer that is greater than the sinle silk insulating layer thickness that the compound area of aluminum-plastic constitutes in addition on the cooperation for the ability of the external signal interference of resistance of cable is strengthened.
