Application:
1.steel-tape armored cable is to be laid underground, the cable could bear certain mechanical force.
2.Steel-wire cable is applicable to the well, underwater with the bottom of sea, the cable cans bear the bigger pressure with lead to pull the dint.
Standard: This product adopts the standards of IEC502 & IEC332-3
Scope of application: This item is applied for the alternating current circuitry with voltage (Uo/U) 0.6/1kV for the power supply.
Working conditions:
1) This maximum working temperature of the conductor is 70°C.
2) During having a short(lasting less than 5 seconds)the maximum temperature of the cable conductor for shall not be above 160°C.
3) Environment temperature should be no lower than 0°C for laying the cable;
4) Bending radius allowance of the cable;
single core cable: no steel tape cable 20D: steel tape cable 15D.
3 core cable: no steel tape cable 15D; steel tape cable 12D.
Notes: D practical external diameter of cable
