The key characteristics of wiring cables include:
Conductor Material: Copper or aluminum is typically used as the conductor material; copper conductors offer superior electrical conductivity and corrosion resistance, while aluminum conductors are relatively more cost-effective.
Insulation Material: Common insulation materials include Polyvinyl Chloride (PVC), Cross-linked Polyethylene (XLPE), and Polypropylene (PP); these materials possess excellent electrical insulation properties and heat resistance.
Sheath Material: The sheath of wiring cables is typically made of Polyvinyl Chloride (PVC), which provides robust mechanical strength and corrosion resistance.
Rated Voltage and Current: The rated voltage and current of wiring cables vary according to the standards of different countries and regions; a common rated voltage is 450/750V, while the rated current is determined by the cross-sectional area of the conductor.
Standard Specifications: The manufacturing and quality standards for wiring cables typically adhere to national or regional wire and cable standards, such as those established by the International Electrotechnical Commission (IEC) or Underwriters Laboratories (UL).
