Copper Tape Screened Medium Voltage XLPE Insulated Power Cable delivers dependable medium voltage transmission with tightly controlled electric stress. This copper tape screened cable wraps a lapped copper tape screen around the insulation, and the inner and outer semi-conducting layers smooth the electric field so the dielectric is not overstressed. For medium voltage xlpe cable runs in substations and urban networks, that electrostatic field control is what keeps partial discharge low and life long.
The screened medium voltage xlpe cable construction starts with a compacted stranded copper conductor, adds an extruded semi-conducting conductor screen, applies a cross-linked polyethylene insulation, then a semi-conducting insulation screen and a copper tape metallic screen. This electrostatic field control prevents harmful voltage stress at 8.7/15 kV, and the copper tape screened cable conducts capacitive and fault currents safely to earth. Every copper tape screened cable length is partial discharge tested, and the medium voltage xlpe cable meets IEC 60502-2 for medium voltage service.

Q: Why use a copper tape screened cable at medium voltage?
A: The copper tape screen and semi-conducting layers control the electric field, so this copper tape screened cable avoids dielectric overstress.
Q: What standard does this medium voltage xlpe cable follow?
A: The medium voltage xlpe cable is manufactured and tested to IEC 60502-2.
Q: How is electrostatic field control verified?
A: By partial discharge testing, which confirms the electrostatic field control of every copper tape screened cable length.
Shenghua applies the semi conducting layers and the copper tape screen under tight tolerance, so the electrostatic field control of every copper tape screened cable is uniform along the length. Each medium voltage xlpe cable passes partial discharge testing to IEC 60502-2, and we measure screen resistance to confirm the copper tape screened cable conducts fault current safely. Because electrostatic field control depends on concentric layers, the medium voltage xlpe cable is checked for screen coverage and sheath integrity. Our engineers advise on bonding and earthing so the electrostatic field control of the copper tape screened cable is effective, and the medium voltage xlpe cable is supplied in single core form for urban and substation routes.
Q: How is electrostatic field control achieved in the copper tape screened cable?
A: Semi conducting inner and outer layers smooth the stress, so the medium voltage xlpe cable maintains dependable electrostatic field control.
Q: Is the medium voltage xlpe cable partial discharge tested?
A: Yes, every copper tape screened cable length is PD tested to IEC 60502-2.
