Product Overview
Designed for critical 110kV transmission networks, this single-core or three-core copper conductor cable delivers high-capacity power flow from primary substations to heavy load centers. Manufactured under strict compliance with IEC 60840 (Power cables with extruded insulation and their accessories for rated voltages above 30 kV up to 150 kV), this model CU/XLPE/PVC/SWA/PVC combines high thermal endurance with mechanical armor, making it ideal for direct burial, tunnels, or outdoor trays in smart grid projects.
Technical correction note: For 110kV, IEC 60502 is not applicable (max 30kV). Our cable strictly follows IEC 60840 to ensure legal compliance and grid operator acceptance.

1. Conductor:
Stranded annealed copper (CU) – Class 2 circular or shaped.
Optional: Longitudinal water blocking or copper tape shielding.
2. Conductor Screen (Semiconductive):
Bonded XLPE-based semi-conducting layer to eliminate air voids and homogenize electrical stress.
3. XLPE Insulation (Main Insulation):
Dry-cured, super-clean XLPE with low dissipation factor.
Thickness per IEC 60840 (typically ≥16mm for 110kV).
Rated temperature: 90°C (normal), 250°C (short circuit).
4. Insulation Screen:
Strippable or bonded semi-conducting layer + swelling tape.
5. Metallic Screen (Copper Wire or Tape):
Helically applied copper wires + counter-helical copper tape.
Earth fault capacity designed per system requirements.
6. PVC Inner Sheath (Bedding):
Extruded PVC protecting the metallic screen and providing a stable base for armor.
7. SWA (Steel Wire Armor):
Galvanized round steel wires.
Protection against rodents, rocks, and mechanical impact for direct burial.
Also serves as a continuous earth path.
8. PVC Outer Sheath (Overseal):
Black UV-stabilized PVC – ST2 or ST7 (low smoke & halogen-free options available).
Printed with voltage, standard, length markers, and manufacturer code.
Why Choose This 110kV CU/XLPE/SWA Cable?
1.High Power Transfer Capacity:
Copper conductor combined with XLPE insulation allows up to 1000A+ continuous current (depending on installation) with minimal dielectric loss.
2. Robust Steel Wire Armor (SWA)
Withstands high pulling tension during installation (≥15 kN per core) and resists external compression in underground or submarine approaches.
3. IEC 60840 Certified
Fully type-tested for partial discharge (≤5pC at 2U₀), impulse voltage (550 kVp), and long-term aging. Suitable for 30+ year service life.
4. Zero Water Treeing (XLPE Grade)
Super-smooth insulation suppresses water tree growth, ensuring reliability in wet soil or high humidity tunnels.
5. Fire Safety Compliance
PVC outer sheath meets IEC 60332-1 for flame retardancy. LSZH (Low Smoke Zero Halogen) outer sheath optional for indoor/urban substations.
