International standard: IEC60502-2:2005 rated voltage 1~30KV extruded insulated power cables and accessories
Additional standard: GB/T 19666-2005 General rules for flame-retardant and fire-resistant cables
Scope of application: It should be used on transmission and distribution lines with 50 Hz AC rated voltage Uo/U of 0.6/1KV and below.
Operating conditions for cable laying
When laying in the air, the center distance of single-core cables when laying in parallel: 185mm2 and below is twice the diameter of the cable; 240mm2 and above is 90mm.
Model | Name | Scope of application |
YJV | Copper core XLPE insulated PVC sheathed power cable | Indoors, tunnels and cable trenches, etc., do not need to bear external mechanical force. Single-core cables are not permitted to be laid in magnetic conduits. |
YJLV | Aluminum core XLPE insulated PVC sheathed power cable | |
YJY | Copper core XLPE insulated PE sheathed power cable | |
YJLY | Aluminum core XLPE insulated PE sheathed power cable |
Features
● YJV cross-linked cables have good mechanical properties, excellent insulation properties, larger transmission capacity than oil-paper insulated cables with the same cross-section, simple production process, and large-scale production.
● XLPE insulated cables have a higher operating temperature (90 °C), which increases the ampacity of the cable, smaller bending radius, light weight, and easier maintenance and installation.
