PVC cables are made from Polyvinyl Chloride (PVC) and offer good flame retardancy and physical properties, but may produce toxic gases and dense smoke when burned. PE cables, on the other hand, use Polyethylene (PE) as the insulating material, known for its excellent dielectric properties and low-temperature resistance, making it suitable for the insulation of high-voltage cables
Composition
Polyvinyl chloride (PVC) or polyethylene (PE) resin.
Fillers: such as aluminum hydroxide, calcium carbonate, etc.
Additives: such as antioxidants, lubricants, UV absorbers, etc.
Pigments: such as inorganic pigments, organic pigments, etc.
Stabilizer: such as heat stabilizer, light stabilizer, etc.
Classification
1. PVC cable: Polyvinyl chloride (PVC) as an insulating material, with good mechanical properties, chemical corrosion resistance and flame retardant. This type of cable is often used in fixed power transmission and construction installation projects.
2. PE cable: polyethylene (PE) as insulation material, with good flexibility, electrical properties and low temperature performance. This type of cable is often used in mobile electrical equipment and outdoor engineering.
Applications
● Power transmission: These cables are often used in fixed power transmission and building installation projects. They have good mechanical properties, chemical corrosion resistance and flame retardancy, ensuring safe and stable power transmission.
● Mobile electrical equipment field: PE cable has the characteristics of flexibility, wear resistance, etc., suitable for mobile electrical equipment and outdoor engineering. Its low temperature resistance makes it possible to maintain good electrical performance in cold environments.
● Industrial automation: PVC or PE cables are widely used in industrial automation systems, such as the connection of sensors, actuators and other equipment. Its anti-interference performance and signal stability provide a reliable guarantee for industrial automation.
● Civil construction field: This type of cable is also commonly used in electrical lines in civil buildings, such as lighting, sockets, etc. Its safety and environmental performance make it an ideal choice for electrical circuits in civil buildings.
