NA2XSY (YJLSV) 6-10(12)kV (Al/XLPE/CWS/PVC）

Medium voltage cables for distribution networks. They are suitable for laying Indoor, tunnel, cable trench, shaft or buried laying. The cable can withstand mechanical external forces and a certain tensile force, it widely used in transformer stations, electric power plants and industrial plants.IEC60502-2

Application

YJLSV (Al/XLPE/CTS/PVC) 3-core medium voltage non-armoured power cable is specifically designed for a wide range of power distribution networks. It provides a dependable connection for generation units and is ideal for various industrial and process applications. You can install this versatile cable directly in the ground, outdoors, indoors, or within cable ducts, offering flexibility for diverse project requirements.

Description

Construction: The N2XSEY – YJLSV cable is built with a carefully engineered multi-layer design to deliver optimal power transmission and durability.
- Conductor: At its core are high-quality aluminum (Al) conductors. These conductors are circular and compacted, ensuring efficient electrical flow and reliable performance.
- Conductor Screen: A non-metallic, semi-conducting compound forms the conductor screen. This layer helps to create a smooth electrical field around the conductor, preventing partial discharges.
- Insulation: The cable features robust XLPE (Cross-linked Polyethylene) insulation. This advanced insulation material provides superior electrical strength, which is essential for medium voltage applications, and contributes to the cable’s high insulation resistance.
- Insulation Screen: An additional non-metallic, semi-conducting compound acts as the insulation screen, working in conjunction with the XLPE to maintain electrical integrity.
- Metallic Screen (CTS): A Copper Tape Screen (CTS), composed of fine copper wires, surrounds the insulation. This metallic screen is crucial for safety, managing electrical fields, and providing protection against electromagnetic interference.
- Fillers and Binders: Non-hygroscopic materials are used as fillers and binders within the cable structure. These components ensure the cable’s stability and maintain its circular shape, especially important for non-armored designs.
- Outer Sheath: The cable is encased in a durable Polyvinyl Chloride (PVC) outer sheath. This outer layer provides robust protection against external mechanical stress, moisture, and environmental factors, making the cable resilient in various conditions.
Main Characteristics: It stands out for its excellent electrical and mechanical properties. It offers minimal dielectric loss, which translates to reduced energy waste during power transmission. The high insulation resistance ensures stable and safe operation across its lifespan.
