Advantages of medium voltage cable
Medium voltage cable features a single-core design with a stranded, compacted circular copper conductor conforming to AS/NZS 1125 standards. The conductor is extruded with a semi-conductive conductor shield, followed by an XLPE insulation layer and a strippable semi-conductive insulation shield, forming a complete medium-voltage insulation and shielding system. A copper wire shield is placed outside the insulation shield, supplemented by spirally wrapped copper tape, allowing for grounding and fault current capacity design according to engineering requirements. The outer sheath is made of black PVC material, providing good mechanical and environmental resistance. The cable structure can also be optionally equipped with longitudinal water blocking, lead alloy metal sheathing, and a nylon anti-termite layer to adapt to different laying conditions.

APPLICATIONS
3.8/6.6 (7.2) kV XLPE insulated single-core copper medium-voltage cable is widely used in commercial, industrial, and urban and residential distribution networks, suitable for medium-voltage power transmission and distribution applications. This cable is commonly used in factory distribution systems, commercial building medium-voltage feeders, connections between small substations and distribution equipment, and urban underground distribution networks. The single-core structure facilitates phase-by-phase installation and system maintenance, and is suitable for fixed installation in cable trenches, conduits, or tunnels, providing safe, stable, and long-term reliable power support for medium-voltage power systems.
Commercial Complexes
It is also widely used in medium-voltage power distribution systems of public buildings such as office buildings, shopping malls, hospitals, and airports, undertaking the task of stable and reliable medium-voltage power transmission.
Industrial Plants
Used in medium-voltage power distribution systems within factories, this cable serves as the main power supply cable between transformers and medium-voltage distribution cabinets or large electrical equipment, meeting the requirements for continuous, high-load operation.
Residential Areas
Used for medium-voltage connections between residential community substations and various distribution nodes, ensuring the safety and stability of power supply to the community.
Tunnel
Suitable for installation in urban underground cable trenches, conduits, or tunnels, used for medium-voltage power transmission and regional distribution, supporting the long-term safe operation of urban power grids.
