Mv Underground Cable XLPE/SWA(STA)/PVC
1. Brief Introduction of XLPE Insulated Power Cable
Cross-linked polyethylene insulated power cable not only has excellent electric, mechanical properties,
But also has powerful resistance against chemical corrosion, heat aging and environmental stress. Its structure
Is simple. The long term operating temperature is 90. It is convenient to use and can be laid with no
Restriction of different level.
Our enterprise can produce both flame retardant and non-flame retardant series of XLPE power cable.
Our XLPE Power cable covers all kinds of low-smoke low-halogen, low-smoke halogen free and three
Classes of A, B, C.
We can design and manufacture special XLPE cable according to the other standards required by the
Customers, such as Heavy section cut apart conductors, water-resistance, defend termites, defend mouse,
And so on.
2. Scope of our Cables
