U-1000 R2V (industrial unarmoured)

Application

U-1000 R2V cables can be used in all low voltage power installations. Multiconductors cables are adapted to remote control and telecontrol installations.

In case of high ambiant temperature, use correction coefficient.

Installation

These cables can be fixed on cable trays, within conduits or fixed to walls. They also can be buried directly with extra mechanical protection.

Cross sections 1,5 - 2,5 and 4 mm² have to be of class 2 flexiblility, if the cable is connected to equipment subject to vibration.

Permissible current and voltage drop are given

For 1 conductor , 4 and 5 conductors and 3 conductors without ground (1x, 3x, 4x,4G, 5x, 5G) according to a THREE PHASE CURRENT
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

For 2 and 3 conductors with ground (2x and 3G); according to a SINGLE PHASE CURRENT =
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
