Abstract

The utility model discloses a kind of inert gas shielding composite cable; the airway tube of inert gas including innermost layer; inert gas is filled with the airway tube, uniformly arrangement is provided with circle extruding bar for the periphery of described airway tube, and the outside for extruding bar is wrapped up by the extruded layer of setting；Uniformly be placed with eight conductors that covering is wrapped up by insulating barrier outside described extruded layer, eight insulating barriers uniformly arranged after by the wrapped stranding of Mica tape layer.The extruding bar made in the utility model in the outside elastomeric material for setting a circle evenly distributed of airway tube; outside conductor is arranged on extruding bar via arranged in a ring after insulating barrier insulation parcel; airway tube can be effectively protected when external pressure is larger not destroyed by crunch; absorbing external partial pressure, increase the service life of airway tube；By Mica tape outside other insulating barrier, increase fire resistance, and set screen layer and waterproof layer to increase shield effectiveness and water resistance.

Description

A kind of inert gas shielding composite cable

Technical field

A kind of the utility model pair twist cable, and in particular to inert gas shielding composite cable.

Background technology

Inert gas composite cable refers to wrap up the airway tube of an inert gas at the middle part of cable, filled in airway tube There is inert gas, conductor can be made to work again in the environment of HTHP under the protection of inert gas, existing inert gas Filling pipe it is most use cross-linking radiation airway tube, certain pressure, bending and tensile force can be born, but actually using When sometimes airway tube receive external pressure it is larger when still can cause conductor tube flexural deformation, reduce and benefit from the life-span, finally Cause conductor tube damaged, inert gas effusion.

Utility model content

The purpose of this utility model is in view of the deficienciess of the prior art, providing a kind of inert gas shielding compound electric Cable, its technical scheme are as follows：

A kind of inert gas shielding composite cable, include the airway tube of the inert gas of innermost layer, filled in the airway tube There is inert gas, uniformly arrangement is provided with circle extruding bar for the periphery of described airway tube, and the outside for extruding bar passes through setting Extruded layer parcel；Eight conductors that covering is wrapped up by insulating barrier, eight insulating barrier quilts are uniformly placed with outside described extruded layer Uniformly pass through the wrapped stranding of Mica tape layer after arrangement；Described lapping layer is coated with screen layer, outside described screen layer Waterproof layer is coated with, described waterproof layer is coated with sheath.

Preferably, the pipe outer wall of described airway tube is additionally provided with some arc grooves, described extruding bar can be uniform Arrangement is arranged in arc groove.

Preferably, described airway tube is arranged to cross-linking radiation airway tube, wall thickness 5mm.

Preferably, described extruding bar is arranged to rubber extruded bar, external diameter is arranged to 2mm；Described extruded layer is same The extruded layer of elastomeric material making is arranged to, the thickness of the extruded layer is 1mm.

Preferably, it is additionally provided with tear rope structure between the insulating barrier of eight described conductors.

Beneficial effect：The utility model has the advantages that：In the utility model one is set in the outside of airway tube The extruding bar that evenly distributed elastomeric material makes is enclosed, outside conductor is via setting arranged in a ring after insulating barrier insulation parcel On extruding bar, extruding bar has certain crimp ability, and airway tube can be effectively protected when external pressure is larger Do not destroyed by crunch, absorbing external partial pressure, increase the service life of airway tube；Pass through cloud outside other insulating barrier Master tape is wrapped, increases fire resistance, and sets screen layer and waterproof layer to increase shield effectiveness and water resistance.

Brief description of the drawings

Fig. 1 is the utility model structure diagram.

Embodiment

Below in conjunction with the accompanying drawings and specific embodiment, the utility model is furtherd elucidate, the present embodiment is with the utility model Implemented under premised on technical scheme, it should be understood that these embodiments are merely to illustrate the utility model rather than limit this reality With new scope.

As shown in figure 1, a kind of inert gas shielding composite cable, includes the airway tube 1 of the inert gas of innermost layer, this is led Inert gas is filled with tracheae 1, uniformly arrangement is provided with circle extruding bar 2 for the periphery of described airway tube 1, and extrudes bar 2 Outside wrapped up by the extruded layer 3 of setting；Eight are uniformly placed with outside described extruded layer 3, and covering is wrapped up by insulating barrier 4 Conductor 5, eight insulating barriers 4 by uniformly arranged after by 6 wrapped stranding of Mica tape layer；Described lapping layer 6 is coated with Screen layer 7, described screen layer 7 are coated with waterproof layer 8, and described waterproof layer 8 is coated with sheath 9.

The pipe outer wall of described airway tube 1 is additionally provided with some arc grooves, and described extruding bar 2 can uniformly arrange installation In arc groove；Described airway tube 1 is arranged to cross-linking radiation airway tube, wall thickness 5mm；Described extruding bar 2 is arranged to Rubber extruded bar, external diameter are arranged to 2mm；Described extruded layer 3 is likewise provided as the extruded layer 3 of elastomeric material making, the extruding The thickness of layer 3 is 1mm；Tear rope structure 10 is additionally provided between the insulating barrier 4 of eight described conductors.

The extruding bar made in the utility model in the outside elastomeric material for setting a circle evenly distributed of airway tube, it is outside Conductor via insulating barrier insulation parcel after it is arranged in a ring be arranged on extruding bar on, extruding bar there is certain crimp energy Power, when external pressure is larger can be effectively protected airway tube is not destroyed by crunch, absorbing external partial pressure, increases Add the service life of airway tube；By Mica tape outside other insulating barrier, increase fire resistance, and screen layer is set and prevented Water layer increases shield effectiveness and water resistance.

Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and Retouching also should be regarded as the scope of protection of the utility model.
