Send An Email6.35-11kV XLPE-insulated medium-voltage power cables are suitable for distribution or secondary transmission networks, typically serving as the primary power supply for commercial, industrial, and urban residential networks. They are applicable to systems with high fault currents rated up to 10kA/1 second. Structures for higher rated fault currents are available upon request. Suitable for static applications in ground, indoors/outdoors, cable ducts, submerged, and where cables are not subjected to significant mechanical stress or tensile strain. Owing to its exceptionally low dielectric loss factor, which remains constant throughout its service life, and the superior insulating properties of XLPE material, this cable exhibits high operational reliability. The conductor shield and semiconductor material insulation are securely longitudinally spliced (single-pass extrusion). Suitable for substations, power stations, and industrial plants.
HV Cable Insulation XLPE has the following advantages:
1.Heat Resistance Performance:
XLPE with reticulated three-dimensional structure has very excellent heat resistance performance. It will not decompose and carbonize below 300℃, the long-term working temperature can reach 90℃, and the thermal life can reach 40 years.
2.Insulation Performance:
XLPE maintains the original good insulation characteristics of PE, and the insulation resistance is further increased.
Its dielectric loss angle tangent value is very small, and it is not greatly affected by temperature.
3.Mechanical Properties:
Due to the establishment of new chemical bonds between macromolecules, the hardness, stiffness, abrasion resistance, and impact resistance of XLPE have been improved, thus making up for the shortcomings of PE which is susceptible to environmental stress and cracking.
4.Chemical Resistance Characteristics:
XLPE has strong acid and alkali resistance and oil resistance, and its combustion products are mainly water and carbon dioxide, which are less harmful to the environment and meet the requirements of modern fire safety.
