This is practical be mainly the supporting electric wire of the serial motor-car vehicle of CRH, be applicable to rated voltage 3.6kv and following various motor-car vehicle and city railway vehicle for distribution system, control system electrical installation cable, there is Environmental Safety, high flame retardant, high-low temperature resistant, LSZH, oil resistant, acid-alkali-corrosive-resisting, be applicable to ambient temperature :-40 DEG C-90 DEG C, still there is under low temperature the performances such as good flexibility.
The utility model cable shield adopts special construction, adds fiber in process of production and carry out mixed weaving during cable braid on the basis of common copper wire woven shield, reaches the protection of mechanical performance to cable and electrical property.After the utility model modified node method, cable has merged the advantage of appeal two kinds of braid shielded modes, can either ensure the transmission of electric power, improves earth leakage protective, also assures that the flexible nature of cable simultaneously.
The feature of the utility model CRH series motor train unit standard wall heavy insulation cable:
1. conductor is stranded tinned conductor; Filament diameter from 0.2 ~ 0.39mm, through stranded composition.
2. the non-toxic high molecular material of insulation and sheath employing.
3., after insulation stranding, carry out fiber and copper wire mixed weaving in insulated outer surface, number of spindles is identical, and direction is contrary.
CRH series motor train unit standard wall heavy insulation rated voltage for cable: 0.6/1kV, 1.8/3kV, 3.6/6kV.
The technical scheme that the utility model CRH series motor train unit standard wall heavy insulation cable is taked is:
A kind of CRH series motor train unit standard wall heavy insulation cable, is characterized in: CRH series motor train unit standard wall heavy insulation cable is made up of insulated wire cores, mixed weaving layer and restrictive coating; Insulated wire cores is formed by extruding insulating barrier outside twisted copper conductors, has mixed weaving layer outside insulated wire cores, and mixed weaving layer is fiber and copper wire mixed weaving structure, is restrictive coating outside mixed weaving layer.
The utility model CRH series motor train unit standard wall heavy insulation cable can also adopt following technical scheme:
Described CRH series motor train unit standard wall heavy insulation cable, is characterized in: fiber is identical with copper wire number of spindles with fiber in the mixed weaving layer of copper wire mixed weaving structure, and direction is contrary.
