Abstract
The invention discloses a 1500 V soft direct current cable capable of preventing mice, temites, and ultraviolet and blocking water, and refers to the technical field of a cable. The 1500 V soft direct current cable is formed by orderly extruding and wrapping five types of soft copper wire conductors, a wrapping layer, an ethylene propylene rubber insulation layer, a linear low-density polyethylene water blocking layer, a high-oxygen index polyolefin fireproof layer, a weaving armor layer and an anti-mice temite-proof low-smoke zero halogen polyolefin outer sheath layer from inside to outside. The 1500 V soft direct current cable is reasonable in design; the conductor adopts five type of copper wire twisting structures, so that the whole softening property of the cable is guaranteed; for adopting the ethylene propylene rubber insulation, the cable insulation performance cannot be reduced under the condition of immersing in the water for a long time; the water blocking layer adopts linear low-density polyethylene with bad water permeability and can stop water out of the insulation layer; the fireproof layer adopts the high-oxygen index polyolefin fireproof layer, so as to ensure the flame-retarding performance of the whole cable; the weaving armor layer is big in density and can effectively prevent mouse biting and temite decaying; besides, the outer sheath adopts anti-mice temite-proof low-smoke zero halogen polyolefin, thus the 1500 V soft direct current cable has the effect of preventing mice and temites.
Description
Technical field
The present invention relates to cable, particularly relate to a kind of termite-resistant rodent-resistant antiultraviolet and to block water the soft direct current cables of 1500V.
Background technology
The each provincial capital in the whole nation is substantially all at construction subway, and the particular/special requirements such as subway 1500V direct current cables requires protection against rodents, termite-proof, antiultraviolet blocks water, therefore the design of the construction of cable just becomes the key met the demands.Subway cable produces stress when mainly considering cable laying or bending installation, there will be cracking phenomena, therefore require that the construction of cable is soft, cable installation environment more complicated, long period of soaking is in water sometimes, and cable must have excellent block-water performance, because cable exposure lays, also need ultraviolet resistance and anti-rat bite and termite moth erosion performance, the stability that subway cable needs is high and longer useful life.Existing cable cannot meet above-mentioned requirements completely.
Summary of the invention
For solving above-mentioned technological deficiency, the object of the invention is to provide a kind of termite-resistant rodent-resistant antiultraviolet and blocks water the soft direct current cables of 1500V.
The solution of the present invention is as follows: a kind of termite-resistant rodent-resistant antiultraviolet blocks water the soft direct current cables of 1500V, is 5 class soft copper silk conductors from inside to outside, belting layer, ethylene propylene rubber insulated layer, LLDPE water blocking layer, high oxygen index polyolefin fireprotection layer, braiding armour and the termite-proof low-smoke halogen-free polyolefin external sheath layer of protection against rodents extrude successively and form.
Described braiding armour forms with the braiding of bare copper wire, tinned copper wire or stainless steel wire, and count is more than or equal to 90%.
The present invention is reasonable in design, conductor adopts 5 class soft copper silk lay configuration to ensure that the softness of whole cable, adopt ethylene propylene rubber insulated meet long term submersion in water situation under insulating performance of cable do not decline, water blocking layer adopts the LLDPE of bad hydraulic permeability, can moisture be blocked in outside insulating barrier, fireprotection layer adopts high oxygen index polyolefin jacket material, ensure the fire resistance of whole cable, braiding armour density is large, can effectively prevent rat from biting and the erosion of white mosquito moth, oversheath adopts the termite-proof low-smoke halogen-free polyolefin material of protection against rodents, there is certain termite-resistant rodent-resistant effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein: 1,5 class soft copper silk conductors; 2, belting layer; 3, ethylene propylene rubber insulated layer; 4, LLDPE water blocking layer; 5, high oxygen index polyolefin fireprotection layer; 6, armour is woven; 7, low-smoke halogen-free polyolefin external sheath layer.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described;
As shown in Figure 1, a kind of termite-resistant rodent-resistant antiultraviolet blocks water the soft direct current cables of 1500V, is 5 class soft copper silk conductors 1 from inside to outside, belting layer 2, ethylene propylene rubber insulated layer 3, LLDPE water blocking layer 4, high oxygen index polyolefin fireprotection layer 5, braiding armour 6 and the termite-proof low-smoke halogen-free polyolefin external sheath layer 7 of protection against rodents extrude successively and form.
Described braiding armouring 6 layers forms with the braiding of bare copper wire, tinned copper wire or stainless steel wire, and count is more than or equal to 90%.
Conductor adopts 5 class soft copper silk lay configuration to ensure that the softness of whole cable, adopt ethylene propylene rubber insulated meet long term submersion in water situation under insulating performance of cable do not decline, water blocking layer adopts the LLDPE of bad hydraulic permeability, can moisture be blocked in outside insulating barrier, fireprotection layer adopts high oxygen index polyolefin jacket material, ensure the fire resistance of whole cable, braiding armour density is large, can effectively prevent rat from biting and the erosion of white mosquito moth, oversheath adopts the termite-proof low-smoke halogen-free polyolefin material of protection against rodents, there is certain termite-resistant rodent-resistant effect, this cable is made to have protection against rodents, anti-ant, antiultraviolet and the function blocked water, and useful life can increase greatly, reduce maintenance cost.
Although give detailed description and explanation to the specific embodiment of the present invention above; but what should indicate is; we can carry out various equivalence according to conception of the present invention to above-mentioned execution mode and change and amendment; its function produced do not exceed that specification contains yet spiritual time, all should within protection scope of the present invention.
