The following are some of the characteristics of DC cables:
1. Conductor material: The conductors of DC cables are usually made of copper or aluminium because of their good conductive properties.Structures Cables
2. Insulation materials: As DC requires a higher insulation capacity, DC cables use materials with high insulation properties such as polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), rubber, etc.Accessories Cables
4. Rated voltage: DC cables are usually rated at a higher voltage than AC cables because of the lower energy losses associated with the transmission of DC power.
5. Application areas: DC cables are widely used in solar power generation systems, electric vehicle charging piles, industrial equipment, DC power transmission and other areas.
When purchasing a DC cable, the right size and material should be selected according to the specific requirements. Important considerations include the required current capacity, the operating environment (e.g. temperature, humidity, etc.), and certification of compliance with relevant electrical safety standards.
