Overview
The YJLW03 64/110kV single-core power cable is designed for high-voltage power transmission networks. It features a copper conductor, cross-linked polyethylene (XLPE) insulation, a corrugated aluminum sheath and a protective polyethylene (PE) outer jacket. The XLPE insulation provides reliable electrical insulation and thermal performance, while the corrugated aluminum sheath serves as a metallic moisture barrier and helps protect the cable core. The PE outer jacket provides additional protection against environmental exposure during suitable installation conditions. This cable is suitable for underground power transmission, substations and utility distribution projects, subject to project design requirements. Conductor cross-section, shielding configuration and installation conditions should be confirmed according to the applicable technical specification.
Key Features
Hermetic Corrugated Aluminum Sheath
Corrugated aluminum sheath provides an effective metallic moisture barrier, helping protect the cable insulation system against moisture ingress and supporting reliable long-term underground installation.
High-Performance XLPE Insulation
Cross-linked polyethylene (XLPE) insulation offers excellent dielectric properties, thermal stability and electrical insulation performance for high-voltage power transmission applications.
High-Conductivity Copper Conductor
The copper conductor provides high electrical conductivity and efficient power transmission. Conductor cross-section can be selected according to load requirements and project specifications.
Durable PE Outer Sheath
The polyethylene (PE) outer sheath provides protection against abrasion, environmental exposure and installation-related damage, helping maintain cable integrity under suitable operating conditions.
Reliable 64/110kV Transmission
Designed for 64/110kV high-voltage power transmission networks, the YJLW03 cable is suitable for utility grid projects, substations and other power infrastructure applications.
Flexible Corrugated Sheath Design
The corrugated aluminum sheath design accommodates cable bending during installation while providing mechanical support. Installation must follow the specified minimum bending radius and applicable cable-handling requirements.
