Abstract
The utility model relates to a metal outer sheath cable, particularly a metal outer sheath cable which has the advantages of good waterproof property, strong pressure resistance and good flexibility. The utility model is characterized in that a welded and formed stainless steel sheath is longitudinally covered outside cable cores, and the surface of the sheath is rolled with closed annular bamboo joint ripples. Thereby, the cable has strong longitudinal water baffling capability. When water enters the end of the cable, or the water enters the end of the cable owing to breakage, and after the water enters the stainless steel outer sheath of the cable, a water baffling layer and a buffer belt of the cable absorb the water, and cause the outer sheath to rapidly expand. Thereby, the bottom of the annular bamboo joint ripples of the cable cores of the cable and the stainless steel outer sheath forms an expansion and closed space, and the longitudinal infiltration of the water is prevented. In addition, the strength of the bamboo joint ripples is higher than that of thread ripples, the utility model can raise the pressure resistance of the cable, and the pressure resistance can be increased above 5%. The annular bamboo joint ripples have good flexibility, thereby, the annular bamboo joint ripples are favorable to cable laying and installation. The cable is especially suitable for transferring electric power by rail traffic, such as light rails, subways, etc.
Description
Technical field
Utility model relates to a kind of metallic jacket cable, relate in particular to a kind of have good water resistance and anti-pressure ability strong, the metallic jacket cable of good bandability.
Background technology
The track traffic cable, because of its particularity, high to fail safe, the reliability requirement of electric power system.Require cable to have protection against rodents, anti-ant, fire-retardant (fire-resistant), low smoke and zero halogen, waterproof, combination properties such as shielding.
Chinese patent 97219880.6 discloses the stainless steel tube (Fig. 4) that a kind of oversheath is welded into by slim stainless steel band, and at the rolling cable that has screw thread 9 to constitute of stainless steel tube outer surface.Though this structural cable is because of adopting stainless steel outer packed pipe, have protection against rodents, anti-ant, anti-flaming function preferably, yet, stainless steel oversheath surface rolling vertically is used to the screw thread that leads to because having, thereby water proofing property is bad, do not have vertical water-proof function, behind end water inlet or oversheath damage and water inflow, the moisture that enters cable can be along the oversheath screw thread to vertical rapid osmotic, thereby block-water performance can not meet the demands.Still having is worth improved place.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides that a kind of water resistance is excellent, anti-pressure ability is strong, the metallic jacket cable of good bandability.
The utility model purpose realizes that main improvement is the screw thread with the rolling vertical conducting of cable stainless steel oversheath, changes the annular ring ripple of vertical blocking-up sealing into, blocks water thereby cable is reached vertically.Specifically, utility model metallic jacket cable comprises insulated wire cores, filler, buffer strip and vertical bag stainless steel sheath, it is characterized in that said vertical bag welding fabrication stainless steel sheath surface rolling has closed ring ring ripple.
The utility model cable can be changed filler and buffer strip material according to different instructions for uses, and as being used as the cable that blocks water, filling and buffer strip then replace to block water and fill and the buffer strip that blocks water; As being used as flame retardant cable, filling and buffer strip replace to fire-retardant filling and fire retardant cushion band, also can fill non-flammable gases such as nitrogen or carbon dioxide in stainless steel sheath; As being used as fire-resisting cable, the cable core conductive surface also can increase flame retardant coating, and filling and buffer strip are replaced with fire-resistant filling and buffer strip, also can increase high flame retardant oxygen barrier flame retardant coating in stainless steel sheath.In addition, cable can also adopt and block water, fire-retardant composite construction, cable is had simultaneously block water, anti-flaming function.
The said insulated wire cores of utility model according to instructions for use, can be single core, also can multicore.
Utility model is used to logical screw thread owing to will indulge bag welding fabrication stainless steel sheath surface longitudinal, changes the annular ring ripple of sealing into, and its annular is sealing process vertically, thereby makes cable have very strong vertical water-resisting ability.When cable end water inlet or damage and water inflow, after moisture enters cable stainless steel oversheath, filled by blocking water of cable and buffer strip absorbs rapidly and expands, thereby forming to expand in the annular ring wave bottom of cable conductor and stainless steel oversheath seals, thereby stoped the longtitudinal dispersion of moisture.In addition, the intensity of ring ripple is higher than the screw thread ripple, can improve the anti-pressure ability of cable, and anti-pressure ability can improve about more than 5%.Besides, annular ring ripple has good bandability, thus more favourable cable laying and installation.The utility model cable is particularly useful for track traffics such as light rail, subway and transmits electric power.
