Underground XLPE Swa PVC Armoured Medium Voltage Cable

Cable Underground PVC/XLPE SWA

1.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.

2.Scope of XLPE Cable

 

 

3.Main technical Characteristics of Cable

4. 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 .

Short circit: (Max.for 5 sec.) 250

Temperature of laying, in air 25

Underground 15

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.
