Detailed Product Description

XLPE insulated power cable has a number of advantages over paper insulated and PVC insulated cable. XLPE 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 cable can be manufactured according to companys specification which is equivalent to IEC 60502, IEC 60332, and IEC 60754. Some of indexes are superior to above international standard IEC.

Some of special XLPE cable can be manufactured according to the other standards required by customs.

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)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.

Characteristics:
1. Long-term operating temperature: 90ºC
2. Laying temperature:≥0ºC
3. MIN bending radius:
                 6 times of OD of cable for non-armored cable
                 12 times of OD of cable for armored cable
4. MAX short-cut temperature: 250ºC for 5s
 

note: ZR can be added before the type designation of flame retardant cable
       WD can be added bofore the type designation of free-halogen and low-smoke

YJY: Applicable in tunnel or pipeline, not able to withstand traction force and pressure
YJY23: Laid underground, can bear outer mechanical force but should not bear a large tractional force
YJY33: Laid indoor, tunnels or mines, can bear outer mechanical force and fairly large tractional force
