Belden H125A03 Series Coaxial Cable, 5000m Cable Length, 75 Ω Characteristic Impedance - H125A03.005000
This Coaxial cable provides a reliable medium for analogue video and signal transmission in industrial and surveillance installations. It is an unterminated, solid-conductor Coax designed for continuous runs on a bulk reel and intended for environments where low smoke emissions and flame-retardant behaviour are required.
Features & Benefits
• 75Ω characteristic impedance for consistent video signal integrity
• 18AWG solid bare copper conductor for stable electrical continuity
• LSZH jacket reduces toxic emission during combustion
• Flame-retardant construction helps limit fire propagation
• Rated minimum −30°C to maximum 70°C for broad operating range
• 1.8dB attenuation to quantify signal loss per standard measurement
• 18AWG solid bare copper conductor for stable electrical continuity
• LSZH jacket reduces toxic emission during combustion
• Flame-retardant construction helps limit fire propagation
• Rated minimum −30°C to maximum 70°C for broad operating range

How is the cable supplied for long installations?
It is provided on a 5000 m bulk reel to facilitate extensive continuous cabling without frequent joints.
What construction detail aids soldering and termination?
The conductor is solid bare copper which offers straightforward soldering and reliable mechanical termination.
How does the sheath perform in safety-critical buildings?
The low-smoke zero-halogen jacket limits corrosive gas and dense smoke, assisting evacuation and equipment protection.
Which measurement indicates its suitability for standard video equipment?
The 75Ω impedance matches typical video inputs and outputs, ensuring impedance continuity across connections.
