Description
Technical field
The utility model belongs to power cable technical field, is specifically related to a kind of cold-resistant Compression-resistincable cable.
Background technology
China is vast in territory, and the north and south temperature difference is large, and especially in the winter time, the outdoor temperature of northeast region-by-region can reach-50 DEG C.In cold weather conditions, plastics and partial rubber understand brittle, cracking, even there will be the phenomenon of self falling.
Because cold weather major part cable there will be cable cover(ing) cracking, embrittlement, if its generation pressure of outer bound pair, the meeting heavy damage construction of cable, even phenomenon leaks outside, and the normal transmission that not only can affect cable also can threaten the life security of people.
Therefore, how improving cold resistance and the crushing resistance of cable, is the current technical issues that need to address of those skilled in the art.
Summary of the invention
The utility model provides a kind of cold-resistant Compression-resistincable cable, has good cold resistance and crushing resistance, is specially adapted to the application of low temperature environment, can use for a long time in-60 ~-30 DEG C, and reduce the harm caused environment.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of cold-resistant Compression-resistincable cable, comprise cable core and be coated on the protective jacket outside described cable core, described cable core is the conductor that some electric units are intertwined, described electric unit comprises metal bare wire and is coated on the butadiene rubber insulating barrier outside described metal bare wire, and described protective jacket comprises solution polymerized butadiene styrene rubber sheath, steel band, armour and silica gel cloth lapping layer from outside to inside.Solution polymerized butadiene styrene rubber has wear-resisting, cold-resistant, the advantage such as heat-dissipating is low, resilience good, shrinkage is low, color and luster is good, ash content is few, purity is high and curingprocess rate is fast, it can be used as the outer protective sleeve of protective jacket, greatly can improve the cold tolerance of cable.Silica gel cloth lapping layer has higher insulation property; high-low temperature resistant; and can play and well block water and heat-blocking action; steel band and armour are set between the two; hardness and the sound construction degree of protective sleeve can be increased; improve crushing resistance, extend the useful life of protective sleeve, cable is better worked.
Preferably, the space between the space between described cable core and silica gel cloth lapping layer, electric unit is all filled with heating filler, is also provided with fire-proof heat-insulating reinforcement in the space between electric unit.The highest heating temp of heating filler is no more than 40 DEG C, utilizes heating filler and has the protective sleeve acting in conjunction of heat-blocking action, being conducive to preventing cable from occurring congealing phenomenon, improves cable useful life.
Preferably, described heating filler is that heat generating fiber is cotton.There is heating functioin, simultaneously also can be fire-retardant, the normal use of cable in low temperature environment can be ensured very well.
Preferably, described fire-proof heat-insulating reinforcement is glass fibre belt.Glass fiber tape adopts high-temperature-resistant high type glass fibre, processes through special process.There is high temperature resistant, insulation, insulation, fire protection flame retarding, corrosion-resistant, ageing-resistant, the feature such as weatherability, high strength, smooth in appearance.Spun-glass insulation heat insulating belt, silicon rubber glass fibre is mainly divided into protect heat insulating belt, glass radiation proof heat-preserving heat-insulating belt etc.
Preferably, described steel band is galvanized steel strip.Can crushing resistance be improved, cable is better worked.
Preferably, described armour is phosphating steel wire.Can crushing resistance be improved, cable is better worked.
The utility model discloses a kind of cold-resistant Compression-resistincable cable, adopt solution polymerized butadiene styrene rubber as the outer protective sleeve of protective jacket, greatly can improve the cold tolerance of cable.Silica gel cloth lapping layer has higher insulation property; high-low temperature resistant; and can play and well block water and heat-blocking action; steel band and armour are set between the two; hardness and the sound construction degree of protective sleeve can be increased; improve crushing resistance, extend the useful life of protective sleeve, cable is better worked.The fill gaps heating filler of the space between cable core and protective sleeve and cable core inside, in conjunction with cold-resistant heat insulation protective sleeve, can ensure that cable normally uses in low temperature environment very well.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the structural representation of a kind of cold-resistant Compression-resistincable cable of the utility model.
