The utility model discloses the locomotive cable electric pressure reaches 30KV, withstand voltage test 75kV15min, and the mechanical strength and the tensile strength of increase cable make the resistant performance reinforcing of buckling of cable.
Description
Technical field
This utility model relates to cable, is specifically related to a kind of locomotive cable.
Background technology
Locomotive cable is mainly the cable that the electrical installation of the distribution system of rail traffic vehicles, control system and signaling system uses, and its ac rated voltage is below 3KV.
Existing locomotive cable can only meet about 100 meters electric locomotive power demands, use the only simple increase cable length of the occasion beyond 100 meters of locomotive cables can not meet the demand of mechanical strength, it is possible to produce fracture because the mechanical force suffered by cable is excessive and cable self is too heavy. Owing to locomotive cable uses under the mal-condition such as high temperature, high radiation, and in use winding, bending easily cause cable bend cracking back and forth, have a strong impact on service life, and frequently change cable and increase cost, affect operation security.
Summary of the invention
The purpose of this utility model is to provide a kind of locomotive cable, and this locomotive cable electric pressure reaches 30KV, pressure test 75kV/15min, increases mechanical strength and the tensile strength of cable, makes the performance enhancement of the resistance to bending of cable.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of locomotive cable, including the cable core being centrally located, inner restrictive coating and low smoke and zero halogen oversheath, it is disposed with the first nylon belt, the first polyethylene layer between described cable core and inner restrictive coating from inside to outside, between described inner restrictive coating and low smoke and zero halogen oversheath, is disposed with the second polyethylene layer, the second nylon belt, the thin winding layer of tinned copper wire and non-woven fabrics lapping layer from inside to outside;
Described cable core farther includes the first copper conductor of being centrally located and outer copper conductor layer, and described outer copper conductor layer is made up of 6 stranded the second copper conductors in the first copper conductor outer surface.
In technique scheme, further improved plan is as follows:
1., in such scheme, described first copper conductor, the second copper conductor form by some copper wires are stranded.
2., in such scheme, described first nylon belt, the second nylon belt are by the wrapped formation of nylon tape.
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that
This utility model locomotive cable, in its inner restrictive coating, outside is respectively arranged with the first nylon belt, the first polyethylene layer and the second polyethylene layer, the second nylon belt, electric pressure reaches 30KV, pressure test 75kV/15min, and insulation does not puncture shielding resistivity: conductor shielding��1000 �� .m; Insulation shielding��500 �� .m;-40 DEG C of low temperature extend and low-temperature impact (not breaking); By single vertical combustion test; Secondly, increase mechanical strength and the tensile strength of cable, make the performance enhancement of the resistance to bending of cable, reduce cracking, increase cable service life, save operation cost, reduce replacement frequency simultaneously, improve security performance.
