RG59 Siamese Coaxial Cable with 2-Conductor Power | 305m Bulk CCTV Wire | Double Jacket RG59+2C

Product Overview: RG59 Siamese Coaxial Cable (305m Bulk)

Our RG59 Siamese Coaxial Cable is the preferred industry standard for professional security and surveillance systems. This innovative RG59+2C design combines a high-performance 75 Ohm RG59 video cable with a dedicated 2-conductor power cable, all neatly bundled under a single, durable double jacket.

Running video and power simultaneously saves considerable time, cost, and labor on installation projects, making this cable essential for commercial buildings, warehouses, and large residential security setups.

Key Features & Construction Details

✅ Integrated Siamese Design (RG59+2C)

The parallel construction allows installers to pull one cable instead of two, simplifying routing, saving conduit space, and providing a cleaner, more professional final installation.

✅ Coaxial Core (RG59)

• Impedance: Precisely engineered to 75 Ohm (±3 Ohm) for optimal video signal transmission and minimal attenuation.

• Center Conductor: Available in BC (Bare Copper) for maximum performance, or CCS (Copper Clad Steel) for cost-effectiveness and increased tensile strength.

• Shielding: High-density braid coverage (95% minimum), essential for rejecting RFI and EMI interference, ensuring a crystal-clear video feed.

✅ Power Conductors (2C)

• Gauge: Typically 18 AWG or 20 AWG (Pure Copper Stranded) for low voltage DC power (12V or 24V).

• Reliability: Uses high-purity copper strands, ensuring reliable current delivery over distance to power cameras, PTZ devices, or baluns.

✅ Durable Double Jacket

The outer double jacket uses high-grade PVC (Polyvinyl Chloride), providing excellent resistance against moisture, abrasion, and UV light (for outdoor-rated versions).

🙋‍♂️ Frequently Asked Questions

Q: What is Siamese Coaxial Cable?

A: Siamese cable refers to the construction where the RG59 video coaxial cable and a separate 2-conductor power cable (usually 18AWG or 20AWG) are permanently molded together under one double jacket. This allows you to run both video and power for a surveillance camera using a single wire run.

Q: Should I choose BC (Bare Copper) or CCS (Copper Clad Steel) for the center conductor?

A:

• BC (Bare Copper): Offers lower resistance and superior signal quality, making it the top choice for longer runs and high-performance video systems.

• CCS (Copper Clad Steel): More economical and offers increased strength, often used for shorter runs.

Q: Can this cable be used for Digital TV (CATV)?

A: No, RG59 is rated at 75 Ohm impedance and is designed for video surveillance and short-distance CATV runs. Modern digital CATV and broadband typically require 75 Ohm RG6 cable, which has a thicker center conductor and lower attenuation.

Q: What gauge is the power wire?

A: The power wires in our Siamese cable are typically 18 AWG or 20 AWG (Pure Copper Stranded). 18 AWG is recommended for longer runs to minimize voltage drop.
