Up to 500kV XLPE Submarine/Underground Cables · ACSR / AAAC Overhead Conductors · OPGW Optical Wires
Kingshark Energy consolidates premium Chinese cable and conductor manufacturing hubs across Jiangsu (Yixing), Zhejiang, and Shandong. We supply extra-high-voltage XLPE insulated submarine and underground power cables (up to 500kV), medium/low-voltage distribution cables, overhead bare conductors (ACSR, AAAC, AACSR), and Optical Ground Wires (OPGW).
Our power cables utilize ultra-pure cross-linked polyethylene (XLPE) compounds (Borealis / Dow Chemical) co-extruded through triple-layer VCV dry-curing catenary lines. This guarantees flawless void-free insulation with negligible dielectric dissipation factor and ultra-low partial discharge.
All cables are supplied on reinforced steel-wood or heavy-duty all-steel ocean freight drums. Drums undergo sealed watertight moisture barrier treatment and are tested in sequence with TDR fault location and high-voltage dielectric withstand checks before ocean loading.
Every product is drawing-verified and audited to IEEE / IEC international norms.
Triple co-extruded XLPE insulated transmission cables for urban grids and renewable step-up connections. Corrugated aluminum or lead alloy sheath for radial and longitudinal water blocking.
