DAHUA DH-PFM941i-59/3-90 RG59 90M COXIAL CABLE WITH POWER CABLLE

Model Name: DH‑PFM941I‑59/3‑90, a combined coaxial and power cable designed for CCTV deployment.

Cable Configuration: Siamese cable bundling RG59 coaxial line and a 3-core power cable within a single sheath.

Total Length: Approximately 90 m (295 ft) per roll.

Coaxial Conductor: Uses oxygen-free copper with a 0.41 mm (26 AWG) diameter for superior video signal integrity.

Coax Insulation: PE foam dielectric with ≥0.8 mm thickness and ~2.0 mm diameter to ensure stable impedance.

Inner Shield (Coax): Single-side aluminum foil with ≥25% overlap for improved shielding.

Outer Shield (Coax): Copper-clad aluminum-magnesium braid (16 strands × 5/0.12 mm), ≥80% density for low interference.

Characteristic Impedance: 75 Ω ± 5 Ω, ideal for video signal consistency.

Power Cable Conductors: Three oxygen-free copper cores (~0.22 mm²) in red, yellow, and gray for organized power distribution.

Power Cable Insulation: PVC, ≥0.3 mm thickness; each core ~1.25 mm diameter.

Outer Sheath: Black PVC outer jacket, ≥0.4 mm wall thickness, rugged yet flexible.

Electrical Resistance:

• Coax conductor ≤ 13.8 Ω per 100 m

• Power conductor ≤ 8.4 Ω per 100 m

Safety Standards:

• Flame retardancy per CPR Eca classification

• Compliance with RoHS 2.0 and REACH regulations

Durability Features: Anti-aging design with high resistance to interference and environmental stress.

Operating Conditions: Functional from –20 °C to +60 °C; installation from 0 °C to +50 °C; storage at –10 °C to +40 °C and < 60% RH.

Packaging: 90 m per roll; dimensions ~250 × 250 × 105 mm; net weight ~2.90 kg, gross ~2.95 kg.

Use Case: Ideal for installing analog CCTV systems—simultaneous transmission of video and power via a single cable, simplifying wiring.

Optimal Applications: Suitable for HDCVI, AHD, TVI, CVBS cameras; most effective for runs up to 90 m.

Warranty: Comes with a standard 2-year manufacturer warranty.
