CONSTRUCTION:
1. CONDUCTOR
– Bare copper class 2 to IEC 60228, round, multiwire stranded and
compact
2. CONDUCTOR SCREEN
– Inner semi-conducting coating
3. INSULATION
– Core insulation of cross-linked polyethylene (XLPE)

– Outer conductive layer extruded and per-manently welded with the
core insulation
Semi-conducting type
– Over the outer semi-conducting layer, a semiconducting tape must
be used.

– copper tapes helically with a minimum thickness of 0,1 mm.
Separator
– Over the screen as well as under outer sheath, a separating layer
must be used (e. g. taping).
6. SHEATH
– Outer sheath of PVC compound

MV XLPE Insulated Copper Cable Introduction:
MV xlpe insulated cable is used for power transmission and
distribution line with voltage rated at 35kv and below. Compared
with PVC Insulated Power cable, XLPE power cable boasts not only
characteristics of excellent electricity, mechanism, heat and
aging- resistant, environment stress-resistant and chemical
corrosion-resistant, but also simple structure, light weight, no
restriction by laying drop, and high temperature allowance for long
term working.
XLPE cable could be able to bear certain traction during
installation, and armoured xlpe cable could external mechanical
forces.
XLPE Insulated Copper Cable Usage Characteristics:
1). Rated power frequency voltage up to 35KV.
2). Max. Permissible continuous operating temperature of conductor:
90℃
3). Max. Short-circuit temperature of the conductor shall not
exceed: (5S maximum duration) 250℃
4). The ambient temperature under installation should not below 0℃
5). The bending radius of a cable should not be less than 15 times
of the cable diameter.
6).The flame-retardant properties of cable comply with grade A, B,
C of GB/T19666-2005 or IEC60332.
