Abstract
The utility model discloses a track traffic is with stable power cable that transmits, including the sinle silk district, the sinle silk district is divided into 8 partitions by the copper line, all is equipped with a copper conductor and ground wire in every subregion, and the sinle silk district is packed by the shielding layer, and the shielding layer is equipped with the insulating layer outward, and the insulating layer overcoat has the protective sheath. The utility model discloses compare with the conventional art, sinle silk district divides equally for several regions that have independent transmission, and when conductor in certain is regional damaged, the interior conductors in other regions still can the regular transmission, does not hinder the transmission of whole piece cable.
Description
Technical field
The utility model belongs to field of cables, is specifically related to a kind of track traffic stable transfer power cable.
Background technology
The technical requirement of existing power cable for rail transit performs GB/T28429-2012: power cable for rail transit and annex, for the electric power transfer of orbit traffic direct current trailer system, its structure is followed successively by from center to skin: cable copper conductor, the insulating barrier of the crosslinked polyethylene extruded or ethylene-propylene rubber or hard ethylene-propylene rubber.When needed, water blocking layer can be had; When needed, watertight composition can be had; When needed, refuge floor can be had; When needed, armour can be had; When needed, the protection overcoat adding chemical agent can be had.After a long time use, certain section of core may damage and cause whole piece cable to use traditional power cable.
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, provides a kind of track traffic stable transfer power cable.
Technical scheme: in order to reach foregoing invention object; the utility model has specifically come like this: a kind of track traffic stable transfer power cable; comprise core district; described core district is divided into 8 deciles by copper cash; a copper conductor and ground wire is equipped with in each subregion; core district is filled by screen, is provided with insulating barrier outside screen, and insulating barrier overcoat has protective sleeve.
Beneficial effect: the utility model is compared with conventional art, and core district divides equally for several region with individual transmission, when conductors against damage in certain region, the conductor in other regions still can normal transmission, does not hinder the transmission of whole piece cable.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
