Abstract
The utility model relates to a conductive wire core structure of a flame retardant cable, which comprises single thin and soft copper wires, wherein the single thin and soft copper wires are twisted at small pitches, and a tin layer is plated on the outer lateral surface of each single thin and soft copper wire or an isolated layer is coated on the outer lateral surface of each single thin and soft copper wire; preferably, the diameter of the single thin and soft copper wire is 0.1-0.3 millimeter, the bunch twisted pitch multiple of the single thin and soft copper wire is smaller than or equal to 16 times, the multiple twisted pitch multiple is smaller than or equal to 10 times, the single thin and soft copper wires are twisted in the same direction, and the outer lateral surface of each single thin and soft copper wire is a smooth and clean surface. The conductive wire core structure of the flame retardant cable has artful design, simple structure, favorable flexibility and bending resistance performance, good electric conductivity, long service life and convenient installation and emergency repair, and is suitable for being used as a conductive wire core of a mine cable.
Description
Technical field
The utility model relates to the cable technology field, and particularly flame retardant cable technical field specifically is meant a kind of conductor wire core structure of flame retardant cable.
Background technology
The colliery is meant special-purpose ground installation and the underground equipment electric wire cable product of coal mining industry with flame retardant cable.The colliery is very complicated with the environmental condition of cable, and condition of work is very harsh, and the zone that gas and coal dust gather is very dangerous again, sets off an explosion easily, causes serious loss of life or personal injury and property loss.Therefore, had higher requirement with the security feature of cable in the colliery.
Because mining cable generally is used for frequent mobile occasion, require cable compliance and resistance to bend(ing) energy good.In addition because rubber insulation material that cable adopted extruding in the process with connecting sulphur equipment, because of the part material of insulation in filling a prescription under the effect of steam, be easy to decompose and be penetrated in the conductor, the conductor oxidation is become fragile, even rupture, and influence the performance of conductor.And the defective that requires the bright and clean no greasy dirt of conductive surface, the most advanced and sophisticated projection of nothing and other infringements to insulate.
Therefore, need provide a kind of conductor wire core structure of flame retardant cable, it has good compliance and resistance to bend(ing) energy, conducts electricity very well, and long service life is convenient to install, rush to repair, and is suitable for the conductor wire core as mining cable.
The utility model content
The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, a kind of conductor wire core structure of flame retardant cable is provided, the conductor wire core structural design of this flame retardant cable is ingenious, simple in structure, have good compliance and resistance to bend(ing) energy, conduct electricity very well long service life, be convenient to install, rush to repair, be suitable for conductor wire core as mining cable.
To achieve these goals, the conductor wire core structure of flame retardant cable of the present utility model has following formation:
The conductor wire core structure of this flame retardant cable is characterized in, the conductor wire core structure of described flame retardant cable comprises soft copper single line, and described soft copper single line is stranded with fine pith, and the lateral surface of described soft copper single line is coated with the tin layer or is coated with separator.
Preferably, the diameter of described soft copper single line is 0.1mm～0.3mm.
More preferably, the diameter of described soft copper single line is 0.2mm.
Preferably, the bundle of described soft copper single line strand pitch multiple≤16 times twists pitch multiple≤10 times again.
Preferably, described soft copper single line is stranded for stranded in the same way.
Preferably, the lateral surface of described soft copper single line is a smooth finish surface.
The beneficial effects of the utility model are specific as follows:
1. the lateral surface of soft copper single line of the present utility model is coated with the tin layer or is coated with separator, soft copper single line is stranded with fine pith, design ingenious, simple in structure, have good compliance and resistance to bend(ing) energy, conduct electricity very well long service life, be convenient to install, rush to repair, be suitable for conductor wire core as mining cable;
2. thereby the stranded in the same way lead flexibility that further improved of the stranded employing of soft copper single line moral of the present utility model;
3. tin layer that the lateral surface of soft copper single line of the present utility model is coated with or coating moral separator are convenient to the slide relative of lead in insulating barrier and are convenient to repairing is installed.

In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.
See also shown in Figure 1, the conductor wire core structure of flame retardant cable of the present utility model, the conductor wire core structure of described flame retardant cable comprises soft copper single line 1, and described soft copper single line 1 is stranded with fine pith, and the lateral surface of described soft copper single line 1 is coated with tin layer 2 or is coated with separator.In concrete enforcement of the present utility model, the lateral surface of described soft copper single line 1 is coated with tin layer 2.Generally, the electric cable for coal mining machine lead of electric drill cable and small bore adopts zinc-plated, and heavy in section electric cable for coal mining machine lead adopts zinc-plated or the bag separator.
Preferably, the diameter of described soft copper single line 1 is 0.1mm～0.3mm.In concrete enforcement of the present utility model, the diameter of described soft copper single line 1 is 0.2mm.
Preferably, the bundle of described soft copper single line 1 strand pitch multiple≤16 times twists pitch multiple≤10 times again.In concrete enforcement of the present utility model, 12 times of the bundle of described soft copper single line 1 strand pitch multiples twist 8 times of pitch multiples again.
In concrete enforcement of the present utility model, described soft copper single line 1 stranded for stranded in the same way.To improve the lead flexibility.
In concrete enforcement of the present utility model, the lateral surface of described soft copper single line 1 is a smooth finish surface.The defective of no greasy dirt, the most advanced and sophisticated projection of nothing and other infringement insulation.
Adopt the conductor wire core of said structure, it has flexibility and resistance to bend(ing) energy preferably, the rubber insulation material that cable adopts is extruding in the process and not to be easy to decomposition under can the effect at steam and to be penetrated in the conductor with connecting sulphur equipment, thereby the performance of conductor can not be affected,, prolonged useful life.
To sum up, the conductor wire core structural design of flame retardant cable of the present utility model is ingenious, simple in structure, has good compliance and resistance to bend(ing) energy, conducts electricity very well, and long service life is convenient to install, rush to repair, and is suitable for the conductor wire core as mining cable.
In this specification, the utility model is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
