Three cores armoured MV HEPR cable 8,7/15 kV

Application

MV network is a key element of the power distribution system to the end-users; its performance and reliability are strictly related to the quality of cable and accessories.

In the medium voltage segment, HEPR insulation permits good cable performance at conductor's operating temperature as high as 90°C, with peaks of 130°C, insulation provides also good short circuit resistance up to 250°C and matches high current carrying capacity with good safety margins.MEDIASTRIPG7 is an easy stripping cable (the outer semiconductor can be removed at room temperature )

Construction

Conductor : copper or aluminium (stranded conductors flexibility class 2)

Insulation : HEPR G7

Screen : copper tapes

Inner sheath: PVC

Armour: Double steel tapes

Outer sheath : PVC

Upon request may provide cables fire retardant according to :

IEC 60332-3-22 (CAT A)
IEC 60332-3-23 (CAT B)
IEC 60332-3-24 (CAT C)
