SIAMESE CABLE RG59 + 2DC 500FT STANDARD WHITE

Product Overview

The 750065 Siamese Coaxial Cable is a dual-jacketed composite CCTV cabling solution engineered for commercial and residential analog high-definition video surveillance installations. By integrating a 75-Ohm RG59U coaxial video transmission line side-by-side with an 18 AWG 2-conductor (18/2 / 2DC) stranded low-voltage power pair, this Siamese configuration allows security installers to run both camera video signal and 12V DC / 24V AC operating power in a single coordinated cable drop. Supplied on a compact 500-foot (152-meter) spool, it halves labor time and keeps raceways, drywall cavities, and ceiling drops clean and organized.

Constructed with a 20 AWG solid center conductor wrapped in gas-injected foam polyethylene dielectric insulation, the video transmission core delivers crisp image clarity across HD-CVI, HD-TVI, AHD (up to 5MP/4K resolutions), and legacy CVBS analog channels. A heavy-duty 95% coverage braided shield provides resistance against electromagnetic interference (EMI) and radio frequency interference (RFI) emitted by fluorescent lighting, electrical conduits, and industrial equipment. The adjacent 18/2 stranded power wire features color-coded red and black insulated conductors designed to minimize DC voltage drop over typical camera runs. Bound in an architectural white PVC jacket with a zip-cord separation groove, the cable peels apart effortlessly for rapid field termination into standard BNC compression/crimp connectors and screw-terminal DC power plugs.

✅ Key Features

• Combined Video & Power (2DC) Architecture: Runs 75 Ω RG59 video transmission and 18/2 DC power in parallel, eliminating redundant cable drops.

• 500FT (152m) Continuous Spool: Convenient jobsite length packaged for smooth dispensing without kinks, knots, or spool binding.

• Dense 95% Braided Shielding: Provides superior rejection of ground loops, cross-talk, and RF/EMI electrical interference.

• Optimized for HD Coaxial Video: Fully compatible with HD-CVI, HD-TVI, AHD, and standard CVBS analog cameras and recorders.

• Heavy-Gauge 18/2 Stranded Power: 18 AWG multi-strand conductors minimize voltage drop over distance compared to lighter gauge security wire.

• Easy-Peel Siamese Webbing: Pre-notched center groove enables clean, tool-less splitting of the power pair from the coaxial lead at termination points.

• Architectural White PVC Sheath: Neutral commercial white finish blends cleanly into painted interior walls, baseboards, and open commercial ceilings.

• Universal BNC & DC Compatibility: Terminates cleanly with standard RG59 BNC compression, crimp, or twist-on connectors, 900057 BNC couplers, and 2.1 mm DC pigtails.
