Abstract

The utility model discloses a combination cable for monitoring, which comprises a radio frequency cable core and a control cable core. The radio frequency cable core and the control cable core are stranded into a bundle to form a combination cable core. A wrapping layer is coated outside the combination cable core. A filling layer which is filled with high temperature resistant glass fiber is arranged between the combination cable core and the wrapping layer. A water resistance layer is coated outside the wrapping layer. A shielding layer, an armored layer and an outer sheath layer are extruded and molded outside the water resistance layer. The composite cable for monitoring is reasonable in structure and design; and by reasonably combining the radio frequency cable core and the control cable core together, multifunctionality of the cable can be improved, the overall performance can be improved, the service life of the cable can be prolonged and the installation and laying of the cable can be convenient.

Description

A kind of monitoring combination cable

Technical field:

The utility model relates to cable, relates in particular to a kind of monitoring combination cable.

Background technology:

Radio frequency cable is the cable of electromagnetic energy in the transmission radio-frequency region; Radio frequency cable is an indispensable element in range radio communication system and the electronic equipment, is used for firm face such as radio communication and broadcasting, TV, radar, navigation, computer and instrument and makes system's branch line, subscribers feeder and other electronic installations.

Shortcomings such as traditional monitoring cable has function singleness, and performance is low, such as radio frequency cable when the cable of the multiple function of needs, just need to install to lay many cables, have caused a lot of inconvenience.

How radio frequency cable and control cable are combined, realized the combination of function, transmission brings certain practicality to information.

The utility model content:

In order to solve the prior art problem, the purpose of the utility model provides a kind of monitoring combination cable, and reasonable in design has realized a cable multiple use, is convenient to install lay, and has improved practicality.

The technical scheme of the utility model is following:

The monitoring combination cable; It is characterized in that: comprise radio frequency cable core and control cable core; The radio frequency cable core constitutes the combination cable core with the stranded bunchy of control cable core, and the combination cable core is wrapped with lapping layer, is provided with the pyroceram silk between combination cable core and the lapping layer and fills the packed layer that constitutes; Lapping layer is wrapped with water blocking layer, and the outer extrusion moulding of water blocking layer has screen, armour, external sheath layer.

Described monitoring combination cable is characterized in that: described radio frequency cable core comprises the alloy conductor of insulating barrier, and insulating barrier is enclosed with internal shield, fireprotection layer, inner restrictive coating outward successively.

Described monitoring combination cable is characterized in that: described control cable core comprises several conductors of wrap insulate layer, the stranded bunchy of several conductors of wrap insulate layer and be enclosed with successively in the outside that the aluminium foil wheat is drawn, flame retardant coating, inner restrictive coating.

Described monitoring combination cable is characterized in that: described fireprotection layer adopts the overlapping wrapped formation of mylar tape.

Described monitoring combination cable is characterized in that: described flame retardant coating adopts the overlapping wrapped formation of synthetic mica tape.

The utility model has the advantages that:

The utility model reasonable in design reasonably combines radio frequency cable core and control cable core, and it is multi-functional to have improved cable, and overall performance gets a promotion, and has prolonged the useful life of cable, lays to installation and has brought facility.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Embodiment:

Referring to Fig. 1:

The monitoring combination cable comprises radio frequency cable core 1 and control cable core 2, and radio frequency cable core 1 constitutes the combination cable core with control cable core strand 2 synthetic bundles; The combination cable core is wrapped with lapping layer 3; Be provided with the pyroceram silk between combination cable core and the lapping layer 3 and fill the packed layer 4 that constitutes, lapping layer 3 is wrapped with water blocking layer 5, and block-water performance improves; Adaptive capacity is good in the wet environment, and water blocking layer 5 outer extrusion moulding have screen 6, armour 7, external sheath layer 8.

Radio frequency cable core 1 comprises the alloy conductor 1-1 of insulating barrier 1-2, and insulating barrier 1-2 is enclosed with internal shield 1-3, fireprotection layer 1-4, inner restrictive coating 1-5 outward successively, and the shielding properties and the fire protecting performance of radio frequency cable core are improved.
