Abstract
The utility model provides a flame retardation flexible cable for a communication power supply, wherein a conductor I is formed through intertwisting TR type flexible circular copper single wires together, thereby enabling the cable to have a small bending radius; a conductor insulating layer 3 is prepared by a flame retardation polyvinyl chloride material, such that the cable is not provided with flame retardation and self-extinguishing performances when an electrical circuit breaks out a fire disaster, thereby achieving A-grade flame retardation demands; gaps between cable cores are filled by a flame retardation filling rope 2; the surface of each cable core is wrapped by a flame retardation wrapping tape 4 in an overlap manner; and an outer sheath 5 is prepared by a flame retardation polyvinyl chloride material to perfect the flame retardation performance of the cable.
Description
Technical field
The utility model designs a kind of communication power supply and uses flame-retardant flexible electric cable, belongs to the power cable field, cable rated operational voltage: 0.6/1KV.
Background technology
Along with communication power supply with the application of cable in existing communication office (station), distribution bin; Original cable better softness, but its fire resistance still has some deficits, in case breaking out of fire; Cable is on fire thereupon; To result in greater loss,, can not adapt to the instructions for use of feed cable in the communications equipment room so the existing communication power supply is used cable.
Summary of the invention
The purpose of the utility model is to provide a kind of communication power supply to use flame-retardant flexible electric cable.
The technical scheme that the utility model adopts is: a kind of communication power supply is used flame-retardant flexible electric cable; Conductor adopts the soft single round copper wire of TR type; Through bunching machine strand with after make conductor insulation with flame-proof polyvinyl chloride; Insulated wire cores is provided with fire-retardant belting layer outward successively, flame-proof PVC protects outward, and the slit between the core is filled by fire-retardant gasket for packing.
Having the following advantages of the utility model:
1, described communication power supply is used flame-retardant flexible electric cable, and conductor adopts stranded the forming of the soft single round copper wire of TR type, makes this kind cable have less bending radius, suits under the environment that communication bureau's (station), distribution bin etc. are had relatively high expectations, to use.
2, described communication power supply is used flame-retardant flexible electric cable, and conductor insulation adopts the flame-proof polyvinyl chloride material, makes this cable when the electric wiring breaking out of fire, have not flame-retarding power and self-extinguishment, reaches the fire-retardant requirement of category-A.
3, described communication power supply is used flame-retardant flexible electric cable, and the slit adopts fire-retardant gasket for packing to fill between the core, simultaneously the fire resistance of complete this cable.
[0008]4, described communication power supply is used flame-retardant flexible electric cable, and it is overlapping wrapped that the cable core surface adopts fire-retardant band to do, simultaneously the fire resistance of complete this cable.
5, described communication power supply is used flame-retardant flexible electric cable, and flame-proof PVC protects outward and adopts the flame-proof polyvinyl chloride material, makes this cable when the electric wiring breaking out of fire, have not flame-retarding power and self-extinguishment, reaches the fire-retardant requirement of category-A.
Description of drawings
Fig. 1 is the structural representation of the utility model, wherein: 1, flexible conductor; 2, gasket for packing; 3, conductor insulation; 4, band; 5, flame-proof PVC protects outward.
Embodiment
Below in conjunction with accompanying drawing the utility model is explained further details:
As shown in Figure 1; The utility model conductor adopts soft single round copper wire 1 stranded the forming of TR type; Conductor insulation 3 adopts the flame-proof polyvinyl chloride material to extrude and forms; The slit adopts fire-retardant gasket for packing 2 to fill between the core, and it is overlapping wrapped that the cable core surface adopts fire-retardant band 4 to do, and flame-proof PVC protects 5 outward and adopts the flame-proof polyvinyl chloride material.
