Abstract

The utility model discloses a cable for a CRH380A motor train unit. The cable mainly comprises an aluminum conductor, a semiconductor shielding layer, a liner layer, an insulating shielding layer, a filling layer, a copper conductor cable core, an insulating layer and a sheath. The aluminum conductor is coated by the semiconductor shielding layer; the semiconductor shielding layer is coated by the liner layer; the liner layer is coated by the insulating shielding layer and the insulating shielding layer is coated by the filling layer. The cable provided by the utility model has good flexibility, and the insulating material adopts an elastomer with a double layer structure. The elastomer not only has the characteristics of low smoke, halogen-free, flame retardation, oil resistance, corrosion resistance and wear resistance, but also has a high voltage withstand grade and good toughness and bending resistance performance. The breakage elongation of the elastomer is up to 350%, meeting the torsion resistant and ultrathin requirements of the cables for the CRH380A motor train unit at a speed of 350 kilometers per hour.

Description

A kind of CRH380A motor train unit cable

Technical field

The utility model relates to field of cables, relates in particular to a kind of CRH380A motor train unit cable.

Background technology

The cable that common motor train unit is used adopts rubber elastomer as insulating material more, can meet the requirement of speed per hour 300 kilometer motor vehicle group cables.Raising along with motor train unit speed, the CRH380A motor train unit speed per hour of being researched and developed by China's autonomous innovation can reach 350 kilometers/time, and when speed per hour reaches 350 kilometers, need the insulating material of cable not only to there is higher withstand voltage, temperature resistant grade, also need to there is resistance to bend(ing) energy and the less outside dimension higher than polyester elastomer, to adapt to the excessive requirement of cable torsional frequency in EMU running.

Utility model content

In order to overcome the defect of above-mentioned prior art, it is good that the purpose of this utility model is to provide a kind of flexibility, the CRH380A motor train unit cable wear-resisting, oil resistance is excellent.

The utility model takes following technical scheme to realize: a kind of CRH380A motor train unit cable, it mainly comprises aluminium conductor, shield semiconductors layer, inner covering, insulation screen, packed layer, copper conductor cable core, insulating barrier and sheath, described aluminium conductor is wrapped with layer of semiconductor screen, described shield semiconductors layer is wrapped with inner covering, described inner covering is wrapped with one deck insulation screen, and described insulation screen is wrapped with one deck packed layer.

In described packed layer, be extruded with copper conductor cable core.

In described packed layer, be extruded with a drainage thread.

The utlity model has in sum following beneficial effect: this cable has good flexibility, simultaneously, insulating material adopts double-deck elastomer, this elastomer is except having low-smoke non-halogen flame-retardant, oil resistant, the characteristic such as corrosion-resistant, wear-resisting, also there is higher voltage withstand class, good toughness and resistance to bend(ing) energy, its elongation at break can reach 350%, can meet resistance to torsion and the ultra-thin requirement of cable for speed per hour 350 kilometer motor vehicle group CRH380A.
