Type and Designation

Using Feature & Main Technical Performances

1. Rated voltage(U₀/U):450/750V.

2.The Max.long - term operating temperature of conductor:

PE insulated cable: 70°C，XLPE insulated cable:90°C

PVC insulated cable:70°C,90°C,105°C (according to the grade of heatproof after the type)

Low- smoking halogen -free flame-retardant PO insulated cable: 70°C, 90°C (according to the grade of heatproof after the type).

3.The Min.laying temperature is:-20°Cfor PE insulated cable 0°C for PVC or HFPO insulated cable.(It should be preheated if it is below the Min. laying temperature)

4.The permitted bending radius:

No less than 12 times of the overall diameter of the cable for which has armor or wrapped shield. No less than 6 times of the overall diameter of the cable for the others.

5.Flame characteristics

The flame retardant cable can pass the test according to GB/T18380 (IEC60332-3): Test method on electrical wires or cables under fire conditions Part 5: Test on bunched wires and cables.

The low-smoking low-halogenflameretardantcablenotonlycanpass testaccording to GB/T18380(IEC60332-3),but also can pass test according to GB/T17651 (IEC61034):Test method on electrical wires or cables under fire conditions Part 7: Measurement on smoke density of wire or cables.

The insulation and sheath material of the cable should be tested as per IEC 60754-1 :the HCL content of the separated out gas in the firing test is no more than 100mg/g.

The low-smoking halogen-free flame retardant cable not only can pass test according to GB /T1838o(iEC 60332-3), but also can pass test according to GB /T17651(IEC61034). The insulation and sheath material of the cable should be tested as per IEC 60754-2, which pH is no less than 4.3 and conductivity should be less than 10us/mm.

6.The D.C. resistance of conductor is show in table 3 and the insulation resistance is show in table 4.
