RG59 Coaxial Cable: A Comprehensive Guide for the Chinese Market

RG59 coaxial cable is a prevalent type of coaxial cable widely used in China’s telecommunications and security industries. Understanding its technical specifications and variations is crucial for selecting the appropriate cable for specific applications. This guide delves into the details of RG59 coaxial cables available from various Chinese manufacturers like Elesun Cable (www.elesun-cable.com), Hongzhou Cable (es.hongzhoucable.com), Zion Communication (www.zion-communication.com), and BDK Cables (es.bdkcables.com).

Technical Features of RG59 Coaxial Cable

RG59 coaxial cables are characterized by their impedance, typically 75 ohms, ideal for video and low-power RF signal transmission. The cable’s construction involves a central conductor, insulation, shielding, and an outer jacket. The materials used for each component significantly impact the cable’s performance. Elesun Cable (www.elesuncable.com), for instance, highlights the use of Foam PE insulation for improved attenuation. Different manufacturers offer variations in shielding materials and construction, influencing signal quality and interference resistance.

Feature	Description
Impedance	Typically 75 ohms ± 2-3 ohms, crucial for signal integrity.
Inner Conductor	Usually bare copper or copper-clad steel (CCS), affecting conductivity.
Insulation Material	Common materials include solid polyethylene (PE) or foam PE, influencing capacitance and signal attenuation.
Shielding	Usually aluminum foil with a braided copper-clad aluminum (CCA) or copper braid for effective EMI/RFI protection.
Jacket Material	Typically PVC or PE, providing environmental protection and durability.
Capacitance	Varies depending on the insulation material and construction, typically around 67pF/m.
Attenuation	Signal loss over distance, dependent on frequency and cable construction.
Operating Temperature	Ranges from -40°C to 80°C, depending on the jacket material.
Diameter	Varies depending on the construction, typically around 6.10mm.

Different Types of RG59 Coaxial Cable

Variations in RG59 coaxial cable arise from the materials used and the cable’s construction. These differences influence the cable’s performance characteristics, suitability for different applications, and overall cost. Hongzhou Cable (es.hongzhoucable.com) offers an RG59 cable with a PVC jacket, while Zion Communication (www.zion-communication.com) provides a “Golden” RG59 cable with enhanced shielding. BDK Cables (es.bdkcables.com) offers RG59 cables with various shielding options. Choosing the right type depends on the specific requirements of your application.

Type	Inner Conductor	Insulation	Shielding	Jacket	Application
Standard RG59	Bare Copper	Solid PE	Aluminum Foil + Braid	PVC	General purpose video and CCTV applications.
RG59 with Foam PE Insulation	Bare Copper	Foam PE	Aluminum Foil + Braid	PVC	Improved attenuation for longer distances.
RG59 with Enhanced Shielding	Bare Copper	Solid or Foam PE	Double Braid or Additional Shielding	PVC or PE	High interference environments, critical signal transmission.
RG59 with Different Jackets	Bare Copper	Solid or Foam PE	Aluminum Foil + Braid	PE	Outdoor or harsh environmental conditions.

FAQs

1. What is the main application of RG59 coaxial cable?

RG59 coaxial cable is primarily used for transmitting video signals, particularly in CCTV systems and cable television networks. Its 75-ohm impedance is well-suited for these applications.

2. What are the key differences between RG59 cables with solid PE and foam PE insulation?

Foam PE insulation offers lower capacitance and better signal attenuation compared to solid PE insulation. This makes it a better choice for longer cable runs or higher-frequency applications.

3. How does the shielding affect the performance of RG59 coaxial cable?

Shielding protects the signal from external electromagnetic interference (EMI) and radio frequency interference (RFI). More robust shielding, such as double-braided or foil-plus-braid, improves signal integrity in noisy environments.

4. What is the typical length available for RG59 coaxial cable?

RG59 coaxial cable is available in various lengths, ranging from short lengths for connecting devices to spools of hundreds of meters for large-scale installations. The length availability varies by manufacturer.

5. Can I use RG59 coaxial cable for high-frequency applications?

While RG59 is suitable for many applications, its higher attenuation at higher frequencies may limit its use in high-frequency applications. Other cable types with lower attenuation might be more appropriate for such scenarios.
