Al/CU Conductor XLPE/PVC Insulated Thin/Thick steel armored PE
Sheathed Power Cable. AL/CU,XLPE
/PVC,SWA/DSTA,PVC/PE
Relative manufacturing standards: IEC60505, BS, DIN,ASTM,JIS or
other standards.
Application
It is used to transmit and distribute power in power transmission
and distribution system of 35kV or lower.
It is generally applied to the fields including power, construction, mines, metallurgy, petrochemical industry
and communication in complete replace of oil immersed paper insulated power cable and in partial replace
of PVC insulated power cable.
Using features
| Rated voltage | Uo/U: 26/35kV, 21/35kV, 12/20 kV (24 kV), 8.7/10kV, 8.7/15kV, 6/6kV, 6/10kV and 0.6/1kV. |
| No. Of core | Single-core, Two-core,Three-core,Four-core,Five-core,Six-core. |
| Installation Environment | The highest allowed operating temperature of conductor for
long-term working is 90oC. In short-circuit (Max. Long-term is no
more than 5 seconds). The highest temperature for conductor is no
more than 250 degree. 4. D. C. Resistance of the conductor complies with the stipulations of international standar. 5. The environment temperature should be no lower than zero degree when lay. Otherwise it should be preheated. 6. The cable is laid without horizontal drop limit. The Min. Bending radius of cables should be no smaller than 12 times of cable outer diameter. |
| Working Frequency Voltage Test | For cable with Uo of 3.6kV or lower: 2.5Uo+2kV/5min without
puncture. For cable with Uo of 3.6Kv~18kV: 3.5Uo/5min without puncture. For cable with Uo of 21kV and 26 kV: 2.5Uo/30min without puncture. |

| Routine tests: | Sample tests: | Type tests: |
| These non-destructive tests are normally carried out on all lengths
manufactured. - Conductor resistivity - Spark test on oversheath - Voltage tests on sheath - D.C. voltage test on oversheath | These potentially destructive tests are normally carried out on
every production run. - Examination of conductor and dimensions - Hot set test for XLPE insulation - Insulation and oversheath thickness - Four hour voltage test | These destructive tests are normally carried out in addition to the
above tests on commencement of a particular cable supply to
validate its design. - Electrical type tests including bending and heat cycle - Non-electrical type tests including mechanical properties after ageing and tests under fire conditions. |
