MV power cable are rated up to 18/30 (36) kV and manly used in MV distribution network. The conductors are copper or aluminium , mostly compacted stranded to shape round insulated core. Their size range from 25 up to 630 sq mm per core and 3 insulated corer are laid up to assembly a cable. Any cable prtections may be applied , including construction and material for direct burial , longitudinal and /or water tightness, anti termite and fire safety.
XLPE power cable has high electric strength, mechanical strength, high-ageing resisting, environmetal stress resisting antichemical corrossion, and it is 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, silane and irradiation crosslinking). The flame-retardant cable covers all kinds of low-smoke low-halogen low-smoke halogen free, and non-smoke nonhalogented and three classes of A, B, C.
Our XLPE power cable can be manufactured according to IEC 60502, IEC 60332, and IEC 60754. Some of indexes are superior to above international standard IEC.
Some of special XLPE power cable can be manufactured according to the other standards required by customs.
XLPE power cable having higher long-term working temperature and greater current rating, at the same environment XLPE cable may be reduced size(nominal cross-section)1or 2 class in comparison with paper and PVC cable. This is not only improve the quality and properties of products, but also reduce cables production costs.

NO. of cable cross: 1 core(Single core),2cores(Double cores),3cores, 4cores(4 equal-section-area cores OR 3 equal-section-area+1 small section area neutral core),5cores(5 3 equal-section-area cores+2 small area neutral cores OR 4 equal-section-area +1 small area neutral cores).We provide armored type and non-armored type for the cables stated above.
Also can do according to the customer's request.
4. Characters of XLPE Cable:
a.Max Long-time operating temperature of XLPE insulated cable is 90°C
b.Installing temperature of cable should not be less than 0°C
c.Max short-circuit temperature is not exceed 250°C,Not more than5 Sec.
d.Unable be laid without the limit of fall with enough mechanical pull,Single core cable can not be laid in iron tube or fixed by circled iron tools around cables
