Product Description

Low Voltage Underground Power Cable
1. Standard.

IEC60502-1. IEC60228.

2. Brief of XLPE Insulated Power Cable

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 resistance, environmental
stress resisting anti-chemical corrosion, 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, silence, and irradiation, cross linking). The flame-retardant cable covers all kinds of low-smoke,
low-halogen, low-smoke halogen free and non-smoke no halogenated and three classes of A, B, C.
Our XLPE cable can be manufactured according to company’s specification which is equivalent to
IEC60502, IEC60332, IEC60754. 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, ar the same environment
XLPE cable may be reduced size (nominal cross section) 1 or 2 class in comparison with paper and
PVC cable. These are not only improving the quality and properties of products, but also reduce cable’s
production costs.

3. Service conditions and Parameters of Cable
The cable is applied to fixed installation for rated voltage 0.6/1KV of power transportation and distribution line.
Max. Rated Temperature of conductor: Nominal Operating 90 degree .
Short circit: (Max.for 5 sec.) 250 degree.
Temperature of laying, in air 25 degree
Underground 15 degree.
For laying, single core, triangle laying for three cables.
Depth of laying in direct:100cm
Coefficient of thermal resistivity of soil 100 .cm/w
The cable can be laid without drop restriction, and the environment temperature shall not be lower than 0 .
Single core, steel tape armoured cable should be only aplied to direct-circuit line.
For nominal insulation thickness, size of armour, over-diameter, weight and current rating of retardantflame
cable of class A,B,C, you should refer to the value of general cable.
