Technical field
The utility model is related to field of cables, and in particular to a kind of resistance to fire-retardant soft electricity of computer of the resistance to tension of mineral insulation
Cable.
Background technology
At present, a kind of communication cable of the computer cable as transmission signal, the development for Communication in China cause are made that
Remarkable contribution.With the development of industry, the overlay area of signal of communication is more and more wider, common tensile type armature of cable layer
It is the pattern using steel wire winding, increases the total weight of cable in this way.The communication cable laying of some big scale lengths is in having
In the larger environment of height fall, often it is damaged or even breaks because cable is conducted oneself with dignity, particularly rain jelly, ice and snow weather etc.
The influence of harsh weather, communication cable are possible to communication signal transmissions be caused to interrupt because of icing, cause the economic damage that can not be saved
It loses.Cable is directly embedded in the area of acid-base function, and armature of cable, lead set or outer jacket is often caused to be corroded, protection
Because by chemical attack or electrolytic etching, protective layer being caused to fail for a long time, insulation reduces layer, also results in cable fault, chemical industry
The cable corrosion situation of unit is just quite serious.
As the footprint that the mankind explore is all over the world, each of the world has also been stretched in the application of computer power cable
Corner can't do without setting foot in the high and cold area of low temperature naturally.Currently, it is narrow to be only applicable to a temperature range for most cables
In room temperature ring, in extremely frigid zones, these cables will appear the serious security problems such as hardening, cracking, embrittlement, will no longer be suitable for height
In cold environment, this will be a very big problem for the supply of electric power of extremely frigid zones.
