Product Structure and Material Characteristics
• Aluminum Alloy Conductor
The conductor is manufactured using aluminum alloy materials. Through optimized conductor structural design, the conductor provides stable electrical conductivity and mechanical strength. Aluminum alloy materials provide advantages in weight control, while maintaining stable electrical performance during long-term operation.
• Insulation Layer
The insulation layer uses plastic insulation materials, commonly adopting a cross-linked polyethylene insulation structure. This material provides stable electrical insulation properties, heat resistance, and aging resistance, allowing the cable to operate under higher temperature conditions.
• Sheath Structure
The outer sheath adopts materials with good environmental resistance, providing effective protection for the internal cable structure. This enables the cable to maintain stable mechanical protection and environmental adaptability during installation and long-term service.
Through a rational structural design, the cable maintains a stable balance between electrical performance, mechanical strength, and environmental adaptability, allowing it to meet the requirements of various engineering applications.
Operating Characteristics
Cross-Linked Polyethylene Insulated Power Cable with Rated Voltage 3.6/6kV to 35kV
In medium-voltage power systems, cross-linked polyethylene insulated power cables provide stable electrical performance and reliable heat resistance. The main operating characteristics are as follows:
• The maximum permissible long-term operating temperature of the cable conductor is 90°C, maintaining stable conductivity during normal operation.
• Under short-circuit conditions, when the short-circuit duration does not exceed 5 seconds, the maximum allowable conductor temperature is 250°C, meeting the safety requirements of power systems under temporary fault conditions.
• During installation, the ambient temperature should not be lower than 0°C, ensuring that cable materials maintain appropriate mechanical performance and flexibility.
• Regarding bending radius requirements, the minimum bending radius of three-core cables is not less than 10 times the cable outer diameter, while single-core cables require a minimum bending radius not less than 15 times the cable outer diameter, maintaining structural integrity and operational reliability during installation.
Cross-Linked Polyethylene Insulated Power Cable with Rated Voltage 0.6/1kV
In low-voltage power distribution systems, cross-linked polyethylene insulated power cables also maintain stable operating performance. The main operating characteristics include:
• The maximum permissible long-term operating temperature of the cable conductor is 90°C, meeting the long-term operation requirements of low-voltage power systems.
• Under short-circuit conditions, when the duration does not exceed 5 seconds, the conductor temperature may reach 250°C.
• The ambient temperature during cable installation should not be lower than 0°C.
• The minimum bending radius is not less than 7 times the cable outer diameter, allowing the cable to maintain installation flexibility and construction convenience.
