What are the models of very fine coaxial cables? What are the UL numbers for very fine coaxial cables?

Extremely thin coaxial line is a kind of cable used to transmit high frequency signals, which has small size, low loss and excellent signal transmission performance. According to different application requirements and standards, there are many models and specifications of very thin coaxial lines. The following are some common very thin coaxial models and their features: 1. RG-178: RG-178 is a commonly used very thin coaxial model with an outer diameter of about 1.78 mm. It is commonly used in low-power, high-frequency applications, such as wireless communication devices, antennas, wireless sensors, and so on. RG-178 wire is typically made with copper conductors and polyethylene insulation. 2. RG-316: RG-316 is one of the more common very thin coaxial models, featuring an outer diameter of about 2.6mm. It excels in high frequency signal transmission and has low signal loss and good impedance characteristics. RG-316 wire is typically made with a copper conductor and polytetrafluoroethylene (PTFE) insulation. 3. RG-178B/U: The RG-178B/U is an improved version of the RG-178 and a common extremely thin coaxial line. It has a similar outside diameter and characteristics as the RG-178, but is optimized for electrical and mechanical performance. RG-178B/U wire is typically made with copper conductors and polyethylene insulation. 4. RG-179: RG-179 is a very thin coaxial line with an outer diameter of about 2.3mm. It is often used for high frequency signal transmission, suitable for television equipment, cameras, monitoring systems and other applications. RG-179 wire is typically made with copper conductors and polyethylene insulation. 5. RG-316DS: The RG-316DS is a double-shielded, very thin coaxial model featuring an outer diameter of approximately 2.6 mm. It uses a double-shielded structure to provide better anti-interference performance and signal integrity for demanding high frequency signal transmission applications. These very thin coaxial line models are often used in wireless communications, television, electronic equipment, aerospace, and other fields, depending on the frequency range of the application, signal requirements, environmental conditions, and other factors. In UL (American Safety Laboratory) standards, UL number refers to the certification number held by UL certified products. For very thin coaxial lines, UL certification ensures compliance with relevant safety and performance standards. Although the specific assignment of UL numbers depends on the manufacturer and product, the following are examples of common UL numbers for very thin coaxial lines: 1. UL20276: UL20276 is a universal UL number for very thin coaxial lines for indoor applications such as televisions, computers, etc. 2.UL21458: UL21458 is the UL designation for a very thin coaxial cable for specific applications, depending on the cable manufacturer and product specifications. Please note that the exact assignment of a UL number is dependent on the UL certification and product specification requirements of the cable manufacturer. Therefore, the most accurate UL number information can be obtained by contacting a particular cable manufacturer or consulting their product documentation.
