8.7/10kV (15kV) Copper Conductor XLPE Insulated Underground Medium Voltage Power Cable

  • 8.7/10kV YJV / YJLV / YJV22 / YJLV22 / YJV32 / YJLV32
  • RMJT
  • IEC 60502-3
Quantity:

Introduction

This cable is used to transmit power on the power transmission and distribution line of A.C.50Hz, rated voltage 35kV or lower. In comparison with PVC insulation cable, it boasts not only excellent electric character, mechanical character, heat and aging-resistant character, environmental stress-resistant character and chemical corrosion- resistant character, but simple structure, light weight, no restriction by laying drop, and high temperature allowance for long-term working as well.


Working conditions:  

1This maximum working temperature of the conductor is 90 0C;

During having a short (lasting less than 5 seconds) the maximum temperature of the cable conductor shall       not be above 250 0C; Environment temperature should be no lower than 00C for laying the cable;

2Bending radius allowance of the cable:

 Single core cable: No steel tape cable 20D; Steel tape cable 15D

Cores cable:  No steel tape cable 15D; Steel tape cable 12D.

 Notes: D practical external diameter of cable.

Be applicable to   the well, underwater with the bottom of sea, the cable cans bear the bigger   pressure with lead to pull the dint.

Hint Specially

The single-core magnetism material packs   the cable is not suitable for to use for the AC power supply back track, the   necessity hour eligibility uses the single-core 62 or 72 type pack the cable.

Disallow the cent to cross the magnetism   piping mutually when single-core cable establish, the in order to prevent   results in the descent that cable transport electric current ability.
