48/66kV Extruded Insulated Power Cable

48/66kV Extruded Insulated Power Cable

Product Description

The 48/66kV Extruded Insulated Power Cable represents a sophisticated transmission solution specifically engineered for the critical interface between medium and high-voltage applications in modern power networks. This cable configuration operates at the technical threshold where transmission efficiency and insulation integrity demand particularly meticulous design considerations. Unlike higher voltage systems requiring extensive space charge management, the 48/66kV cable achieves optimal performance through precision-engineered material interfaces and geometrically optimized stress control. The system's architecture begins with high-purity copper or aluminum conductors, progressing through a seamlessly extruded trilayer core of conductor screen, XLPE insulation, and insulation screen—each layer manufactured in a continuous process to eliminate microscopic imperfections and ensure perfect interfacial bonding.

At the heart of this high-voltage cable's reliability lies its advanced dielectric system, where specially formulated cross-linked polyethylene provides not only exceptional short-term dielectric strength but, more critically, demonstrates remarkable resistance to long-term electrical aging and water tree propagation. The semiconducting shields are engineered with controlled resistivity profiles that create a perfectly gradient transition at both conductor and insulation boundaries, effectively smoothing electrical stress distribution without creating charge accumulation zones. This cable incorporates a high-conductivity metallic screen system that performs dual functions: providing a low-impedance path for fault currents while simultaneously creating a symmetrical radial field configuration. The protective sheath system is custom-engineered for installation-specific challenges, offering graded resistance to mechanical stress, chemical exposure, and thermal cycling according to deployment requirements in underground ducts, direct burial, or submerged environments.

This 48/66kV cable platform serves as the workhorse solution for contemporary grid enhancement projects, offering particular advantages in capacity upgrades where space constraints prohibit overhead line expansion. Its technical design specifically addresses the voltage-range challenges where traditional materials approach their performance limits, making it ideal for substation interconnections, industrial park feeders, and coastal renewable energy integrations. The cable's balanced design philosophy—optimizing electrical performance without over-engineering—delivers exceptional value in applications requiring robust performance at this specific voltage tier, including urban infill projects, island interconnections, and industrial complex expansions where reliability requirements justify underground solutions without necessitating ultra-high voltage capabilities. This makes the 48/66kV cable not merely a scaled version of higher-voltage designs, but a purpose-engineered solution for the distinctive technical and economic requirements of this critical voltage segment in the modern power transmission hierarchy.
