When designing power systems for homes or businesses, what are your primary concerns? Cable safety, durability, or transmission efficiency? Poor choices can lead to operational inefficiencies or even pose serious safety risks. With XLPE insulated single-core cables, these worries become a thing of the past.
Exceptional Performance Through Advanced Engineering
XLPE insulated single-core cables, also known as cross-linked polyethylene insulated cables, have become indispensable in power transmission due to their outstanding electrical and physical properties. These cables feature high-quality annealed bare copper conductors, ensuring stable current transmission with minimal loss. The XLPE insulation layer provides exceptional heat resistance, chemical corrosion resistance, and mechanical strength, enabling reliable operation in various challenging environments.
Structural Analysis: The Foundation of Reliability
XLPE insulated single-core cables typically consist of these key components:
-
Conductor: Made of annealed bare copper, available in either solid single-strand or multi-strand configurations. Multi-strand designs offer greater flexibility for easier installation and bending.
-
Insulation layer: Composed of XLPE material treated with a specialized cross-linking process that alters its molecular structure, significantly enhancing heat resistance, electrical strength, and mechanical properties.
-
Optional sheath: Some cables include an additional PVC sheath for extra mechanical protection and weather resistance, extending service life.
Quality Assurance Through International Standards
Manufacturing and testing of XLPE insulated single-core cables strictly adhere to international standards including AS 5000.1, IEC 60502, and BS7889. These standards specify requirements for materials, construction, electrical performance, mechanical properties, and environmental resistance, guaranteeing consistently high-quality products.
Comprehensive Specifications for Diverse Applications
These cables are available in multiple specifications to meet various application requirements. Common sizes include 1.5 mm², 2.5 mm², 4 mm², 6 mm², 10 mm², 16 mm², 25 mm², 35 mm², 50 mm², 70 mm², and 95 mm². Selection should be based on actual load requirements and installation conditions.
