Ⅰ,Brief introduction
With the characteristics of stable performance,advanced technology,broad materials resources,low prices,good flexible and easy to lay and maintain, the polyvinyl chloride insulated power cable is used in fixing lay-up on transmission and distribution electric lines of 50 Hz A.C rated voltage 10 KV or below.
Ⅱ,Application properties
1,Long term permissible working temperature of cable conductive core is not more than 70°C.
2,During short circuit (maximum permanent time is not more than 5 seconds),Temperature of cable conductor is not more than 165°C.
3,The difference level of lay-up cable is not restricted. When laying the cable, temperature of laying is not low than 0°C.
4,They have a good chemical stability, acid resistance, alkali resistance, salt resistance, oil resistance, solvent resistance and flame retardant properties..
5,Light weight, good bending properties and easy to install and maintenance.
| Type | Name | Application |
| VV VLV | Copper(aluminum)core, PVC insulated and sheathed power cable | Mainly laid indoors. Channels, cable slot, tube and other places which can not bear greater pulling and pressure force. |
| VY VLY | Copper(aluminum)core, PVC insulated, PE sheathed power cable |
| VV22 VLV22 | Copper( aluminum)core, PVC insulated, steel tape armoring PVC sheathed power cable | The cables can be laid indoors, in channels, cable slot and direct burial. The cable can bear mechanical force but can not bear greater pulling force. |
| VV23 VLV23 | Copper(aluminum)core, PVC insulated, steel tape armoring PE sheathed power cable |
| VV32 VLV32 | Copper(aluminum)core, PVC insulated, fine steel wire armoring PVC sheathed power cable | Laid indoors, in mining well and water, can bear mechanical force and pulling force. |
| VV33 VLV33 | Copper(aluminum)core, PVC insulated, fine steel wire armoring PE sheathed power cable |
| VV42 VLV42 | Copper(aluminum)core, PVC insulated, thick steel wire armoring PVC sheathed power cable | Laid indoors, in mining well and water, bear greater pulling force. |
| VV43 VLV43 | Copper(aluminum)core, PVC insulated, thick steel wire armoring PE sheathed power cable | As above |
