Description Of Medium Voltage (up to 35kV) XLPE Insulated Power Cable
Rated Temperature: 90℃
Rated Voltage: up to 26/35kV
Reference Standard: IEC60502-2
Conductor: Shaped and circular stranded copper conductors
Insulated: Insulated with Cross-linked polyethylene
Sheathed: PVC
Medium voltage (up to 35kV) XLPE insulated power cable utilize chemical cross-linking (peroxide-initiated) or physical irradiation processes to convert linear polyethylene molecules into a three-dimensional thermosetting network structure. This transformation enhances the material’s thermal stability, elevating its maximum operating temperature from 75°C (thermoplastic PE) to 90°C (short-circuit withstand up to 250°C), while retaining superior dielectric properties.
Application of Medium voltage (up to 35kV) XLPE insulated power cable:
Urban Distribution Networks: Medium-voltage connections between ring main units (RMUs) and transformers.
Industrial Power Supply: Main feeder lines in chemical plants, refineries, and corrosive environments.
Rail Transit: Power transmission for traction substations and electrified rail systems.
Renewable Energy: PV plant step-up circuits/Wind farm collector lines
Submarine Cables: XLPE insulation with lead-sheath protection for subsea power transmission (≤35 kV).
