Type and Designation

Using Feature & Main Technical Performance

1. Rated voltage U₀/U includes 0.6/1kV, 1.8/3kV,3.6/6kV,6/6kV,6/10kV, 8.7/10kV, 8.7/15kV,12/20kV, 21/35kV,26/35kV.

2. The highest operating temperature allwed of conductor for long-term working is 90°c.In short-circuit (Max.long-term is continue no more than 5 second),The highest temperature of conductor is no more than 250°C.

3.D.C. Conductor resistance complies with the stipulations of GB/T3956.

4. Environment temperature in laying the cable should be no lower than 0°c.Otherwise it should be preheated. The Min. bending radius should be no smaller than 15 times of cable outer diameter.

5. The cable is laid without drop limit.

6. Working Frequency Voltage Test:

    for cable with U₀ of 3.6kV or lower: 2.5 U₀+ 2kV/5 min without puncture;

    for cable with U₀ of 3.6kV or higher: 2.5 U₀/5 min without puncture.

7. Partial Discharge Test:

    The discharge volume should be no more than 20pC under 1.73U₀ for the cable with U₀ of 1.8kV or higher & 18kV or lower and no more than 10pC under 1.73U₀ for the cable with U₀ of higher than 18kV.

8. Flame-retardant Character:

    Flame-retardant cable could endure firing test in bundle stipulated in GB/T18380 (IEC60332-3):

    Low smoke & low halogen flame-retardant cable could endure firing test in bundle stipulated in GB/T18380 (IEC60332-3), and smoke density in firing should comply with stipulations of GB/T17651 (IEC61034). HCL content of gas separated out in firing should be no more than 100mg/g and comply with IEC60754-1;

    Low smoke & halogen-free flame-retardant cable could endure firing test in bundle as GB/T18380 (IEC60332-3). Smoke density in firing should comply with stipulations of GB/T17651 (IEC61034). PH value of solution water of gas separated out should be less than 4.3, and electric conductivity rate should be no more than 10us/mm and comply with stipulations of IEC60754-2.
