RG59+2C Power Cable Surveillance Cable for CCTV Camera System


RG59+2C Power Cable Technical Data
1.Cable Structure & Components
The cable is essentially two cables in one jacket:
Component | Description | Typical Specification |
A. Coaxial Part (RG59/U) | Transmits high-frequency video signals. |
|
- Center Conductor | Solid bare copper or copper-clad steel (CCS). | 20 AWG (0.81 mm) |
- Dielectric | Polyethylene (PE) foam insulation. | Diameter ~3.7 mm |
- Shield 1 | Aluminum foil laminate (100% coverage). | Provides primary shielding against EMI. |
- Shield 2 | Tinned copper braid (usually 60-95% coverage). | Provides secondary shielding and ground path. |
- Overall Jacket | Polyvinyl Chloride (PVC). | UV-resistant for outdoor use. |
B. Power Conductors (+2C) | Transmits low-voltage DC power. |
|
- Conductors | Two insulated, stranded bare copper wires. | 18 AWG or 20 AWG (common) |
- Insulation | Color-coded PVC (e.g., Red/Black, Brown/Blue). | For polarity identification. |
C. Integrated Jacket | A single, durable outer jacket holding all components together. | PVC, often black for outdoor use. |
2. Key Electrical Specifications
For the RG59 Coaxial Section:
· Impedance: 75 Ohms (standard for video).
· Velocity of Propagation: ~66% (for foam PE dielectric).
· Capacitance: ~54 pF/ft (17.7 pF/m).
· Attenuation (Critical for video quality):
· Maximum Operating Voltage: Typically 300V RMS.
For the +2C Power Section:
· Conductor Size: Most commonly 18 AWG.
· Maximum Current Capacity (Chassis Wiring per NEC): ~10 Amps per conductor (depends on insulation rating and bundle).
· Typical Practical Use: Used for 12V or 24V DC camera systems. For a 12V system with a 30W camera drawing ~2.5A, 18 AWG is sufficient for runs up to 150-200 feet without significant voltage drop. For longer runs, thicker conductors (e.g., 16 AWG) are recommended.
· Insulation Resistance: >100 MΩ·km.
3. Physical & Environmental Specifications
· Overall Diameter: Approximately 7.0 - 8.0 mm.
· Weight: ~50 kg/km (varies by manufacturer).
· Temperature Range:
· Bend Radius: Minimum 10x the cable diameter (~70 mm).
· Jacket Rating: Standard is CM/CMR (Communications Riser). Outdoor versions have UV-resistant PVC.
4. Primary Applications
This cable is almost exclusively designed for:
CCTV / Surveillance Systems: Powers a single camera and carries back the analog video signal (BNC connection).
Analog HD Systems (HD-TVI, HD-CVI, AHD): Works perfectly for these modern analog formats over coaxial systems.
Other Composite Systems: Can be used for any device requiring separate power and a coaxial signal, like some old audio/video remotes.
5. Advantages & Limitations
Advantages | Limitations / Considerations |
Single-Run Installation: Saves time, labor, and conduit space by pulling one cable instead of two. | Voltage Drop: The power conductors are relatively thin. For long runs (>200 ft) or high-power devices, voltage drop can be an issue. Calculate drop before use. |
Cost-Effective: Lower total cost compared to buying separate RG59 and power cable. | Signal Interference: Poor quality cables may have crosstalk where power induces noise in the coaxial line. Quality shielding (95% braid + foil) is essential. |
Neat and Professional Appearance: Creates a cleaner installation. | Not for AC Mains Power: Designed for Low Voltage DC only (typically 12/24V). NEVER use for 110V/240V AC. |
Ideal for Standard CCTV Cameras: Perfectly matched to the requirements of most dome and bullet cameras. | Rigidity: Thicker and less flexible than standard RG59, making tight bends more difficult. |
6. Comparison with Other Common Cables
Cable Type | Best For | Key Difference |
RG59+2C |
Power + Analog Video to a single device (CCTV). | Composite design. |
RG59 Siamese | Power + Analog Video with separate, parallel cables. |
Coax and power are distinct cables fused side-by-side; easier to split. |
RG59 (alone) | Video only (e.g., cable TV, antenna, video between components). | No power conductors. |
UTP + Power Cable | Power + Digital Video/IP Camera. Requires two separate runs or a PoE switch. | Different signal type (digital data vs. analog RF). |
7. Installation Tips
Termination: Use a proper RG59 compression BNC connector on the coaxial end. Strip carefully to avoid nicking the braid.
- Power Polarity: Observe the color coding on the power wires (e.g., Red = Positive+, Black = Negative-) consistently at both the power supply and camera ends.
- Strain Relief: At the camera housing, secure the cable to relieve stress on the connections.
- Distance: Calculate voltage drop for your specific camera's amperage over the intended run length. Use a voltage drop calculator.
