1~35KV underground armored power cable medium voltage
XLPE insulated cable:
1-35Kv power cable is a kind of XLPE insulated cable, suitable for medium voltage to high voltage; it consists of compact stranded aluminum wire or stranded copper wire as bare conductor, with XLPE insulation and metal shielding layer, PVC sheath or PE sheath Cover to prevent corrosion.

1KV 33KV XLPE power cable structure
Conductor: Common annealed stranded compacted round copper or aluminum round conductor in accordance with IEC60228 level 2
Conductor shielding: extruded semiconducting compound
Insulation: XLPE (cross-linked polyethylene) rated temperature is 90°C
Insulation shielding: extruded semiconducting compound
Wire Mesh: Concentric layers of copper tape or copper wire
The color of the core wire logo: red, yellow, and blue tape should be pasted between the insulating shielding layer and the metal shielding layer (the above logos can be changed as needed);
Assembly: Stack the three shielded core wires together, if necessary, fill with non-hygroscopic materials compatible with insulating materials, and cover with a layer of PVC sheath
Inner sheath: PVC ST2 or PE extrusion layer, low smoke and halogen free
Armouring: three-core power cable with double wires of galvanized steel tape or galvanized steel wire, double wires of single power cable with aluminum foil or aluminum wire
Outer sheath: PVC type ST2, in line with IEC 60502 or PE, LSZH
XLPE (cross-linked polyethylene) power cable has excellent electrical and physical properties and is the best cable for transmission and distribution lines. The advantages of these cables are simple structure and light weight; in addition to excellent electrical, thermal, mechanical and chemical resistance, they also have the convenience of application. It can also be placed along the route without being restricted by the level difference.
Used in power transmission and distribution systems of 35kV and below. It can completely replace oil-impregnated paper-insulated power cables, and can also partially replace polyvinyl chloride-insulated power cables. It is widely used in power, construction, mining, metallurgy, petrochemical, and communications fields.
