Abstract
The utility model discloses a kind of motor train unit electric wire, include conductor, butyronitrile polyvinyl chloride insulation layer and tin plated steel wire woven shield is coated with successively in the outside of described conductor, form core by being coated with water resistance aramid fiber yarn packed layer, the heat insulation lapping layer of aluminium foil, dacron thread braid and plastic-aluminum combined membrane shield layer after two conductor pair twists successively in outside, after being placed side by side by two cores, be coated with LWA light wire armoured flame retardant coating, copper strips spiral winding covering and cold-resistant butyronitrile oversheath successively in outside.The utility model structure is simple, and be surrounded by butyronitrile polyvinyl chloride insulation layer and tin plated steel wire woven shield outside conductor, insulation shielding is effective, and resistance toly draws resistance to compression, also has the characteristic that fire prevention is cold-resistant.
Description
Technical field
The utility model relates to field of cable technology, particularly relates to a kind of motor train unit electric wire.
Background technology
Along with the raising of motor train unit speed, the CRH380A motor train unit speed per hour researched and developed by China's autonomous innovation can reach 350 kilometers/time, and when speed per hour reaches 350 kilometers, the insulating material of cable is needed not only to have higher withstand voltage, temperature resistant grade, also need that there is higher resist bending performance and less outside dimension, to adapt to the requirement that in EMU running, cable torsional frequency is excessive.
Utility model content
The utility model object is exactly the defect in order to make up prior art, provides a kind of motor train unit electric wire.
The utility model is achieved through the following technical solutions:
A kind of motor train unit electric wire, include conductor, butyronitrile polyvinyl chloride insulation layer and tin plated steel wire woven shield is coated with successively in the outside of described conductor, form core by being coated with water resistance aramid fiber yarn packed layer, the heat insulation lapping layer of aluminium foil, dacron thread braid and plastic-aluminum combined membrane shield layer after two conductor pair twists successively in outside, after being placed side by side by two cores, be coated with LWA light wire armoured flame retardant coating, copper strips spiral winding covering and cold-resistant butyronitrile oversheath successively in outside.
Described conductor is twisted by many tin-coated copper tow and forms.
The utility model has the advantages that: the utility model structure is simple, and be surrounded by butyronitrile polyvinyl chloride insulation layer and tin plated steel wire woven shield outside conductor, insulation shielding is effective, and resistance toly draw resistance to compression, also there is the characteristic that fire prevention is cold-resistant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of motor train unit electric wire, include conductor 1, butyronitrile polyvinyl chloride insulation layer 2 and tin plated steel wire woven shield 3 is coated with successively in the outside of described conductor 1, form core by being coated with water resistance aramid fiber yarn packed layer 4, the heat insulation lapping layer of aluminium foil 5, dacron thread braid 6 and plastic-aluminum combined membrane shield layer 7 after two conductor 1 pair twists successively in outside, after being placed side by side by two cores, be coated with LWA light wire armoured flame retardant coating 8, copper strips spiral winding covering 9 and cold-resistant butyronitrile oversheath 10 successively in outside.
Described conductor 1 is twisted by many tin-coated copper tow and forms.
