U-1000 RVFV 3G25 cut to length

Application

These U-1000 RVFV cables are suitable for direct burial without additionnal protection or for installation on cables trays or in ducts where mechanical protection is necessary (bursting risk).

Core stranding

Cores stranded with filler.

Installation

Burried directly in the ground.

Outside on cable trays, within conduits or fixed to walls.

Permissible current and voltage drop are given

a) in free air, sheltered from sun, on cable tray or bracket, on cable ladder, and spaced from the wall, temperature = 30°C.
b) buried with thermal resistivity of the ground 1Km/W, laying depth : 600 mm, temperature = 20°C.

If conditions are differents, apply correction factors from NF C 15-100 standard  or equivalent national standard
 

Voltage drop

Calculated with cosj = 0,8
