FAQ From Customers
-
What is the structure of an overhead insulated cable?
Overhead insulated cables typically consist of a conductor, insulation layer, and an optional outer sheath. The conductor is usually made from aluminum or copper, providing excellent electrical conductivity. The insulation layer, made from materials like cross-linked polyethylene (XLPE) or PVC, protects the conductor and prevents accidental contact with live wires. An optional outer sheath is added for additional mechanical protection and durability, particularly in harsh environmental conditions. -
What materials are used for the insulation of overhead insulated cables?
The insulation of overhead insulated cables is typically made from cross-linked polyethylene (XLPE), which offers superior thermal stability, electrical insulation properties, and resistance to environmental factors. Alternatively, PVC (polyvinyl chloride) can be used for lower voltage applications. These materials help prevent electrical hazards by ensuring that the conductor remains safely insulated, especially in outdoor and exposed environments such as overhead power lines. -
How are overhead insulated cables manufactured?
The manufacturing process of overhead insulated cables begins with the conductor preparation, which involves drawing aluminum or copper to the desired size. The insulation layer is then applied using extrusion technology, ensuring uniform thickness and durability. For high voltage cables, the insulation is cross-linked to improve performance at elevated temperatures and resist electrical stress. The outer sheath is then added, providing protection against physical damage and environmental conditions. The entire process follows stringent quality control and testing procedures to ensure reliability and compliance with international standards such as IEC and ANSI. -
What makes overhead insulated cables suitable for high voltage applications?
Overhead insulated cables are suitable for high voltage applications due to their specialized insulation materials such as cross-linked polyethylene (XLPE), which provides excellent electrical strength and thermal stability. These materials prevent the risk of electrical leakage and offer protection against high voltage surges. The cables' mechanical strength and weather-resistant outer sheath ensure long-term durability and performance, even in extreme environments. Additionally, the insulated layers prevent external damage from wind, moisture, and physical contact, making them ideal for high-voltage power transmission. -
How do overhead insulated cables protect against environmental factors?
Overhead insulated cables are designed to withstand environmental challenges such as moisture, extreme temperatures, UV radiation, and mechanical stress. The insulation material, typically XLPE or PVC, offers excellent resistance to corrosion and weathering, ensuring long-lasting performance even in harsh climates. The outer sheath further protects the cable from abrasion, chemical exposure, and physical damage, ensuring that the cables maintain their integrity and electrical safety during their service life.
