Abstract
The invention relates to a metal net interval type three-core medium-pressure energy-saving capacity-increasing cable comprising single-core cables, metal nets, a stainless steel strip and inflaming retarding plastic pipes, wherein the stainless steel strip is internally provided with the three single-core cables and bundles the three single-core cables with gaps left, and the centers of the single-core cables are provided with plug cores formed by the metal nets; the air inflation type inflaming retarding plastic pipes are arranged among cable cores of the single-core cables, and the inflaming retarding plastic pipes are internally filled with high-efficient inflaming retarding foaming agents. The metal net interval type three-core medium-pressure energy-saving capacity-increasing cable is provided with the cores formed by the metal nets so that the heat dissipating surfaces of original three cables which are closed by being mutually contacted are mutually independent and transparent, thereby being beneficial to the convection of air and the conduction of heat energy; and in addition, the invention can achieve the purpose of high-efficient inflaming retarding to fundamentally cancel all auxiliary fireproof measures in cable tunnels, such as a firewall, a fire retardant packet, plugging mud, and the like, has good heat dissipating effect and enhances the current-carrying capability.
Description
Technical field
The present invention relates to a kind of cable, relate in particular in a kind of metal net interval type three-core and press energy-saving capacity-increasing cable.
Background technology
Press 8.7/10-26/35kV level cable single core and two kinds of forms of three cores generally to be arranged in existing as the transmission line of city looped network.Single-core cable has good heat dissipation effect, feature that current capacity is strong, but electric parameter big and the three-phase line transmission inconsistent (reactance of laying at interval as three-core parallel) because it takes up room, be easy to cause threephase load unbalanced and lay workload big (need lay three times with three-core cable relatively) and relative position instability, isosceles triangle lays the three-phase single-core cable and understands occurrence positions and move the deterioration that causes transmission quality under mechanical force; In addition, three-core cable Stability Analysis of Structures, equalization parameter, lay and simple and directly once finish, thermal resistance between core is big, the defective of radiating effect difference but exist, and the single-core cable current capacity will descend about 30% relatively.Combine the advantage of single core, two kinds of cables of three cores and exempt from but separately shortcoming at this present situation metal net interval type three-core midium voltage cable, reach to lay and simple and directly once finish, Stability Analysis of Structures, equalization parameter, good heat dissipation effect, current capacity are big, and have the advantage little, that anti-flaming function is strong that takes up room.
Summary of the invention
Purpose of the present invention provides in a kind of metal net interval type three-core and presses energy-saving capacity-increasing cable, and Stability Analysis of Structures, equalization parameter, good heat dissipation effect, current capacity are big, to overcome the above-mentioned deficiency of existing single-core cable and three-core cable.
The present invention is achieved through the following technical solutions:
Press energy-saving capacity-increasing cable in a kind of metal net interval type three-core, comprise single-core cable, woven wire, stainless steel band, flame retardant plastics pipe, described stainless steel band inside is provided with three single-core cables and gap-like is tied up, the center of three single-core cables is provided with the plug core that is made of woven wire, be provided with the flame retardant plastics pipe of inflation shape between the core of described single-core cable, be filled with the highly effective flame-retardant blowing agent in three flame retardant plastics pipe pipes.
Press the beneficial effect of energy-saving capacity-increasing cable to be in the metal net interval type three-core of the present invention: by being provided with the plug core that constitutes by woven wire, make the existence of original three cable heat-delivery surface invar screen grids that are in contact with one another and seal and penetrating independently of one another, help the convection current of air and the conduction of heat energy; The flame retardant plastics pipe of three inflation shapes will spray enough intumescent flame retardents reach highly effective flame-retardant with the space of stopping up cable core and steel belt layer formation purpose, fundamentally can cancel auxiliary fire prevention measures all in the cable tunnel, as fire compartment wall, back-fire relief bag, shutoff mud etc.; Because good heat dissipation effect, can improve 33%--35% than the current capacity of the three-core cable of its equal specification.
Description of drawings
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the cross sectional representation of pressing energy-saving capacity-increasing cable in the described metal net interval type three-core of the embodiment of the invention.
Among the figure:
1, single-core cable; 2, woven wire; 3, stainless steel band; 4, flame retardant plastics pipe; 5, highly effective flame-retardant blowing agent.
Embodiment
As shown in Figure 1, press energy-saving capacity-increasing cable in the described metal net interval type three-core of the embodiment of the invention, comprise single-core cable 1, woven wire 2, stainless steel band 3, flame retardant plastics pipe 4, described stainless steel band 3 inside are provided with three single-core cables 1 and gap-like is tied up, thereby make the position relative fixed of three single-core cables 1, the center of three single-core cables 1 is provided with the plug core that is made of woven wire 2, make the existence of original three cable heat-delivery surface invar screen grids that are in contact with one another and seal and penetrating independently of one another, therefore help the convection current of air and the conduction of heat energy; Be provided with the flame retardant plastics pipe 4 of inflation shape between the core of described single-core cable 1, be filled with highly effective flame-retardant blowing agent 5 in three flame retardant plastics pipes 4, can prevent to be subjected to the fire invasion and attack when having the function of support, these three plastic tubes will spray enough intumescent flame retardents reach highly effective flame-retardant with the space of stopping up cable core and steel belt layer formation purpose, can fundamentally cancel auxiliary fire prevention measures all in the cable tunnel, as fire compartment wall, back-fire relief bag, shutoff mud etc., its flame retardant rating can reach the level of super category-A.
