Product Description

1. Brief of XLPE insulation Power Cable

    XLPE insulation power cable has a number of advantages over paper insulated and PVC insulated cable. XLPE cable has high electric strength, mechanical strength, high-aging resisting, environmental stress resisting anti-chemical corrosion, and simple construction, using convenient and higher operating of long term temperature. It can be laid with no drop restriction.

    Various of flame-retardant and non-flame retardant XLPE cable can be manufactured with three technology (peroxide, silance and irradiation crossing-linking). The flame-retardant cable covers all kinds of low-smoke, low-halogen, low-smoke halogen free, and non-smoke non-halogenated and three classes of A, B, C.

    Our XLPE cable can be manufactured according to company’s specification which is equivalent to IEC 60502, IEC 60332, IEC 60754. Some indexes are superior to above international standard.

    Some of special XLPE cable can be manufactured according to the other standard required by customers.

    XLPE cable having higher long term working temperature and greater current rating, at the same environment XLPE cable may be reduced size (nominal cross-section) 1 or 2 class in comparison with paper and PVC cable. This is not only improve the quality and propertied of products, but also reduce cable’s production costs.

Nominal Cross-section Main core 2.5 4 6 10 16 25 35 50
Neutral core 1.5 2.5 4 6 10 16 16 25

 
 

Nominal Cross-section Main core 70 95 120 150 185 240 300 400
Neutral core 35 50 70 70 95 120 150 185

 
4. Main technical Characteristics of Cable
   1) D.C .Resistance: Conductor resistance of finished cable per kilometer at 20oC is not more than the following:
 

Nominal Cross-section  mm2 15 2.5 4 6 10 16 25
Cu core 12.1 7.41 4.61 3.08 1.83 1.15 0.727
Al core 18.1 12.1 7.41 4.61 3.08 1.91 1.20
Nominal Cross-section  mm2 35 50 70 95 120 150 185

Al core 0.868 0.641 0.443 0.320 0.253 0.206 0.164
Nominal Cross-section  mm2 240 300 400 500 630 800 1000
Cu core 0.0754 0.0601 0.0470 0.0366 0.0283 0.0221 0.0176

 
  2) Voltage Test
     Each drum of finished cable should withstand power frequency voltage 3.5kv for 5 minutes, the insulation is not breakdown.

  3) Service conditions and parameters of cable
     The cable is applied to fixed insulation for rated voltage 0.6/1kv of power transportation and distribution line.
     Max. rated temperature of conductor nominal operating 90oC.
     Short circuit: max. for 5 sec. 250oC.
     The cable can be laid without drop retriction, and the environment temperature shall not be lower than 0oC.
