Abstract
The utility model relates to a reinforced steel-core detection cable, which is characterized in that the cable mainly comprises a plurality of conductors, insulating layers and a sheath layer, each conductor is in a mixed and stranded structure which is made of a plurality of bare copper wires and steel wires, the external surfaces of the conductors are wrapped by the insulating layers, and the sheath layer is arranged on the external surfaces of the conductors which are wrapped by the insulating layers. The reinforced steel-core detection cable has the beneficial effects that since each conductor is in the mixed and stranded structure and high-density polyethylene and low-density polyethylene are mixed and extruded at high pressure, the elongation and the bearing capacity of the cable are ensured; since a lapping layer is cancelled and the insulating layers and the sheath layer are connected tightly, the tensile force of the cable is ensured; and since the sheath layer is made of specially excellent polyvinyl chloride which is reinforced and extruded at high pressure, the tight connection between a cable sheath and the insulating layers is ensured and the tensile strength of the cable is improved.
Description
Technical field
The utility model belongs to cable, relates in particular to a kind of reinforced steel core exploration cable.
Background technology
Adopt bare copper conductor in the process structure of plain edition steel core exploration cable, the phenomenon that cable is elongated or breaks in use appears in common polythene insulation, lapping layer and pvc sheath easily.The centre is provided with lapping layer, and it is loose that insulating barrier is linked to each other with restrictive coating, can't guarantee the pulling force of cable.Environment for use requires little, the no pulling force layer of cable of the outside diameter of cable itself, relies on cable itself to come bearing equipment fully, as the connecting line between the connection device on down-hole or colliery time and the ground, then needs to research and develop a kind of reinforced steel core exploration cable.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provide a kind of reinforced steel core exploration cable, itself has good weight capacity, conductor adopts bare copper conductor to mix stranded, insulating barrier employing low density polyethylene (LDPE) with steel wire to mix with the high density polyethylene (HDPE) hyperpressure and extrude, remove lapping layer, sheath adopts the reinforced ultra high voltage of extra best best polyvinyl chloride to extrude, and has successfully solved the problem that cable is elongated easily or breaks.
The utility model for achieving the above object, by the following technical solutions: a kind of reinforced steel core exploration cable, it is characterized in that: mainly constitute by some conductors, insulating barrier and restrictive coating, described conductor is that the multiply bare copper wire mixes lay configuration with steel wire strand, conductor outer surface coated insulation layer, the described some conductor outer surfaces that are coated with insulating barrier are provided with restrictive coating.
The mixing lay configuration of described conductor adopts one group of steel wire and six groups of bare copper wire lay configuration, or adopts three groups of steel wires and nine groups of bare copper wire lay configuration.
Beneficial effect: conductor adopt to mix lay configuration and adopts high density polyethylene (HDPE) and low density polyethylene (LDPE) mixed high-voltage power to extrude, and has not only guaranteed percentage elongation but also has guaranteed the bearing capacity of cable; The cancellation of lapping layer makes insulating barrier closely link to each other with restrictive coating, has guaranteed the pulling force of cable; Restrictive coating adopts the reinforced extreme pressure of extra best best polyvinyl chloride to extrude, and has guaranteed that cable cover(ing) is connected with the tight of insulating barrier, has strengthened the pull-off force of cable simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of conductor among Fig. 1.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of reinforced steel core exploration cable, mainly constitute by some conductors 1, insulating barrier 2 and restrictive coating 3, described conductor is that multiply bare copper wire 4 mixes lay configuration with steel wire strand 5, conductor outer surface coated insulation layer, the described some conductor outer surfaces that are coated with insulating barrier are provided with restrictive coating.The mixing lay configuration of described conductor adopts one group of steel wire and six groups of bare copper wire lay configuration, or adopts three groups of steel wires and nine groups of bare copper wire lay configuration.
Design principle: every performance index that this cable proposes according to the client, the analysis-by-synthesis structure is passed through the adjustment to the cable material and the construction of cable, and comprehensively selects for use special substance to make this cable itself have weight capacity.This product adopts mixed structure, and conductor adopts bare copper conductor to mix stranded, insulation employing low density polyethylene (LDPE) with steel wire to mix with the high density polyethylene (HDPE) hyperpressure and extrude, removed lapping layer, and the reinforced extreme pressure of sheath employing extra best best polyvinyl chloride is extruded.Realized the requirement that cable itself can the load-bearing detecting devices.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
