Abstract
The utility model relates to a frequency converter cable comprising a main sheath, a shielding layer, main insulating layers, a main conductor, side sheaths, auxiliary insulating layers and an auxiliary conductor. The shielding layer is sleeved in the internal part of the main sheath. The main insulating layers are evenly and symmetrically distributed in the internal part of the shielding layer. The main insulating layers wrap the external side of the main conductor so that wire cores are formed. Three threads of the wire cores are twisted so that a cable core is formed. The side sheaths are evenly and symmetrically distributed in a gap between the shielding layer and the cable core. The auxiliary insulating layers are respectively installed in the side sheaths correspondingly. The auxiliary insulating layers wrap the external side of the auxiliary conductor. The frequency converter cable has advantages of being reasonable in structural design, low in manufacturing cost and long in the service life so that the internal part of the cable can be protected, normal work of equipment is ensured, defects of a conventional frequency converter cable of being liable to be broken and fractured are solved, and the service life of the cable is prolonged.
Description
Technical field
The utility model relates to a kind of cable, specifically a kind of converter cable.
Background technology
Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety meets rate and domestic market occupation rate all over 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes first electric wire producing country in the world.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.The structure of converter cable comprises three main line insulated wires, three zero line insulated wires; at main line insulated wire and zero line insulated wire, set gradually interior lapping layer, copper strips layer, outer lapping layer and external sheath layer outward; form 3+3 core structure; make cable there is stronger proof voltage impact; pulse voltage in the time of standing at a high speed frequent frequency conversion, plays a good protection to frequency conversion electrical equipment.
Yet in daily use procedure, unavoidably can converter cable is crooked or dilatory, if things go on like this can make converter cable occur skin breakage or the fracture of cable inner conductor, especially zero line, itself is comparatively tiny, and do not take any safeguard procedures, in crooked or dilatory for a long time process, very easily occur fracture having influence on the normal use of equipment.
Summary of the invention
It is a kind of reasonable in design, low cost of manufacture, long service life that technical problem to be solved in the utility model is to provide, thereby can play a protective role and guarantee the cable of the normal work of equipment, i.e. a kind of converter cable cable inside.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A converter cable, comprises main sheath, screen, main insulating layer, leading body, side sheath, auxiliary insulating layer and auxiliary conductor, and described screen is sleeved on the inside of main sheath; Described main insulating layer is distributed in the inside of screen symmetrically, and the outside that described main insulating layer is wrapped in leading body forms core, by stranded the forming of compenzine core, forms cable core, and described side sheath is distributed in the gap between screen and cable core symmetrically; Described auxiliary insulating layer respectively correspondence is arranged in side sheath, and described auxiliary insulating layer is wrapped in auxiliary conductor outside.Adopt side sheath to play the effect of protection to auxiliary insulating layer and auxiliary conductor, thereby effectively avoided because of cable bending or the dilatory auxiliary conductor that causes, rupturing in routine use process, guaranteed the normal use of equipment.
Described side sheath ovalize structure, the medial surface of side sheath is mutually circumscribed with auxiliary insulating layer, the lateral surface of side sheath respectively corresponding with the medial surface of screen, the lateral surface of main insulating layer is mutually circumscribed.Utilize side sheath to fill up in the gap between screen and main insulating layer, can increase the degree of packing of cable on the one hand, also avoided on the other hand contacting between auxiliary insulating layer and screen, main insulating layer, effectively prevented because the auxiliary insulating layer that between auxiliary insulating layer and screen, main insulating layer, phase mutual friction causes breaks, thereby extended the life-span of auxiliary insulating layer, for the normal operation of equipment provides safeguard.
Described side sheath is made by the elastomeric material of good toughness; even bending or drag cable in daily use procedure like this; only can produce extruding by offside sheath; and utilize the toughness of side sheath to play buffer protection function to auxiliary insulating layer and auxiliary conductor, can not produce destruction to auxiliary insulating layer and auxiliary conductor.
The beneficial effects of the utility model are: the utlity model has the advantages such as reasonable in design, low cost of manufacture and long service life; thereby can play a protective role and guarantee that equipment normally works cable inside; solve the easy fracture of traditional converter cable existence, the defect of breaking, extended the useful life of cable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is internal structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of side sheath of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below the utility model is further set forth.
As shown in Figure 1 to Figure 2, a kind of converter cable, comprises main sheath 1, screen 2, main insulating layer 3, leading body 4, side sheath 5, auxiliary insulating layer 6 and auxiliary conductor 7, and described screen 2 is sleeved on the inside of main sheath 1; Described main insulating layer 3 is distributed in the inside of screen 2 symmetrically, the outside that described main insulating layer 3 is wrapped in leading body 4 forms core, by stranded the forming of compenzine core, form cable core, described side sheath 5 is distributed in the gap between screen 2 and cable core symmetrically; Described auxiliary insulating layer 6 respectively correspondence is arranged in side sheath 5, and described auxiliary insulating layer 6 is wrapped in auxiliary conductor 7 outsides.Adopt side sheath 5 to play the effect of protection to auxiliary insulating layer 6 and auxiliary conductor 7, thereby effectively avoided because of cable bending or the dilatory auxiliary conductor 7 that causes, rupturing in routine use process, guaranteed the normal use of equipment.
Described side sheath 5 ovalize structures, the medial surface of side sheath 5 is mutually circumscribed with auxiliary insulating layer 6, the lateral surface of side sheath 5 respectively corresponding with the medial surface of screen 2, the lateral surface of main insulating layer 3 is mutually circumscribed.Utilize side sheath 5 to fill up in the gap between screen 2 and main insulating layer 3, can increase the degree of packing of cable on the one hand, also avoided on the other hand contacting between auxiliary insulating layer 6 and screen 2, main insulating layer 3, effectively prevented because the auxiliary insulating layer 6 that between auxiliary insulating layer 6 and screen 2, main insulating layer 3, phase mutual friction causes breaks, thereby extended the life-span of auxiliary insulating layer 6, for the normal operation of equipment provides safeguard.
Described side sheath 5 is made by the elastomeric material of good toughness; even bending or drag cable in daily use procedure like this; only can produce extruding by offside sheath; and utilize the toughness of side sheath to play buffer protection function to auxiliary insulating layer and auxiliary conductor, can not produce destruction to auxiliary insulating layer 6 and auxiliary conductor 7.
