Abstract
The utility model discloses a high-temperature resistant compensation cable, which comprises a cable core, wherein the cable core comprises a plurality of cable conductors which are wrapped by insulating layers and shielding layers from inside to outside sequentially; a cladding layer wraps a plurality of cable conductors wrapped by the insulating layers and the shielding layers; a sheath layer wraps the cladding layer; a plurality of circular hollow filling pipes are filled in gaps among the cable conductors wrapped by the insulating layers and the shielding layers; and a drainage wire is arranged on the outer wall of each of the circular hollow filling pipes. The high-temperature resistant compensation cable has a simple structure and is convenient to manufacture; compared with the conventional fillers, the hollow filling pipes are light in weight and firm; and the drainage wires are arranged outside the filling pipes, so that the drainage effect is good.
Description
Technical field
The utility model relates generally to field of cables, relates in particular to a kind of high temperature resistant compensating cable.
Background technology
Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety satisfies rate and domestic market occupation rate all above 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes first in the world electric wire producing country.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.China's economic growth continuously and healthily; For cable products provides the huge market space, the temptation that Chinese market is strong makes the world all focus on Chinese market to sight; Reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry lets the world regard with special esteem.Along with the continuous expansion of industry sizes such as China Power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.
The application of electronic computer, instrument and meter is universal day by day, and people's awareness of safety constantly strengthens, and the performance and the environmental requirement of the cable supporting with it also improved constantly.Existing computer and instrument are high temperature resistant not high with fire resistance with cable, and the security reliability of cable is low under fire condition, and shielding properties and interference free performance are not high, are not suitable for as densely populated and higher to device security reliability requirement place.
Therefore, be badly in need of a kind of high temperature resistant, anti-flammability, shielding, high temperature resistant compensating cable that anti-interference is good, safe.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of high temperature resistant compensating cable to be provided.
The utility model is realized through following technical scheme:
High temperature resistant compensating cable; Include cable core; It is characterized in that: described cable core includes a plurality of cable conductors that are enclosed with insulating barrier, screen from inside to outside successively, and a plurality of outsides that are enclosed with the cable conductor of insulating barrier, screen are enclosed with belting layer, and the outside of belting layer is enclosed with restrictive coating; Gap between the described cable conductor that is enclosed with insulating barrier, screen is filled with a plurality of circular hollows and fills pipe, and described circular hollow is filled on the outer wall of pipe and is furnished with drainage thread.
Described insulating barrier adopts crosslinked polyethylene.
Described external sheath layer adopts polyolefin.
The utility model has the advantages that:
The utility model is simple in structure, manufacturing is convenient, and the filling hollow pipe is more in light weight, firm than other fillers, and drainage thread cloth is outside filling pipe, and effect is better.
Description of drawings
Fig. 1 is the structural representation of the utility model.
