Securiflex RG59 Premium Coaxial Cable | DCA, LSZH, UV, 75 Ohm, 100m | Black

FAQs

What makes this cable both “premium” and “LSZH Dca”?

This cable combines two premium features: a bare copper conductor for superior electrical performance, and an LSZH jacket with enhanced CPR Dca fire rating for maximum safety. The bare copper conductor provides lower resistance (<42Ω/km) and better signal quality compared to copper clad steel alternatives, enabling longer cable runs and superior HD video performance. The LSZH Dca jacket provides enhanced fire safety - it will not emit toxic halogen gases, produces limited smoke (s1b), has very low combustion gas acidity (a1), and minimal flaming droplets (d2). This combination makes it the ultimate choice for professional CCTV installations in public buildings where both signal quality and fire safety are critical requirements.

What does the CPR Dca rating mean and how is it better than Eca or Fca?

CPR Dca is a significantly enhanced fire performance classification under the Construction Products Regulation compared to basic Eca or Fca ratings. The “Dca” classification indicates limited contribution to fire, while the sub-classifications provide additional safety assurances: s1b means limited smoke production (better visibility for evacuation); a1 means very low acidity of combustion gases (reduced corrosive damage and health risks); d2 means minimal production of flaming droplets or particles (reduced fire spread). Dca-rated cables are required in many public buildings, escape routes, and safety-critical installations where basic Eca or Fca ratings are insufficient. This enhanced rating makes the cable suitable for the most demanding fire safety applications.

Why is LSZH important for public buildings?

LSZH (Low Smoke Zero Halogen) is critically important for public buildings because in a fire, the cable will not emit toxic halogen gases (like chlorine or bromine from burning PVC) and produces significantly less smoke. In public spaces such as schools, hospitals, shopping centres, and transportation facilities where large numbers of people may need to evacuate, reduced smoke improves visibility for safe evacuation, and the absence of toxic halogen gases reduces health risks and corrosive damage to equipment. Many building regulations and fire safety codes specifically mandate LSZH or similar low-toxicity cables in public access areas. The combination of LSZH properties with Dca fire rating provides maximum fire safety compliance.

Can this premium LSZH cable be used outdoors?

Yes, the UV-resistant LSZH formulation makes this cable suitable for outdoor installations and exposed applications. While basic LSZH compounds can degrade under UV exposure, this premium version is specifically formulated with UV resistance to withstand sunlight without deterioration. The extended operating temperature range (-40°C to 70°C) also makes it suitable for harsh outdoor environments. However, for direct burial applications, conduit or duct is recommended for additional mechanical protection. For aerial installations, cable runs along building exteriors, or any exposed outdoor CCTV application in public areas, this UV-resistant LSZH Dca cable provides the ideal combination of weather resistance, fire safety, and premium signal performance.

How does bare copper performance compare to copper clad steel for CCTV?

Bare copper provides approximately 12-15% lower resistance than copper clad steel (<42Ω/km vs <48Ω/km), resulting in measurably better performance: less signal loss over distance allowing 15-20% longer cable runs; improved signal-to-noise ratio for clearer images; better high-frequency performance critical for HD video over coax systems; and more consistent performance across temperature variations. For professional installations in public buildings using HD cameras or requiring long runs, the premium bare copper conductor ensures the best possible image quality. Combined with LSZH Dca fire safety, this cable provides both technical excellence and safety compliance for demanding public building applications.

Where should CPR Dca cables be specified?

CPR Dca-rated cables should be specified for: public buildings with stringent fire safety requirements; escape routes and evacuation corridors; schools, hospitals, care facilities, and other life-safety-critical buildings; shopping centres, cinemas, theatres, and entertainment venues; transportation facilities (airports, train stations, bus terminals); office buildings and hotels with public access; any installation where building regulations mandate enhanced fire performance beyond basic Eca/Fca; and installations requiring compliance with the highest fire safety standards. The Dca rating with s1b-a1-d2 sub-classifications meets the most demanding fire safety codes, making this cable suitable for environments where occupant safety is the primary concern.

Is this cable suitable for HD video over coax systems?

Yes, the premium bare copper conductor makes this cable particularly well-suited for HD video over coax systems (HD-CVI, HD-TVI, AHD). The lower resistance (<42Ω/km) reduces signal loss at the high frequencies used by HD video systems, resulting in clearer images, better colour reproduction, and more reliable signal transmission over distance. For HD video applications in public buildings where LSZH fire safety is also required, this premium LSZH Dca cable provides the ideal solution - combining the signal quality needed for high-resolution cameras with the fire safety compliance required for public access environments. Professional installers specify this cable for HD CCTV installations in schools, hospitals, and other public buildings requiring both performance and safety.

What is the service life of LSZH cable compared to PVC?

Modern UV-resistant LSZH compounds, like that used in this premium cable, provide service life comparable to PVC cables – typically 25-30 years or more under normal operating conditions. Early LSZH formulations sometimes had durability concerns, but current premium UV-resistant LSZH materials offer excellent aging properties, mechanical strength, and environmental resistance. The UV resistance specifically prevents degradation from sunlight exposure that would damage non-UV-rated cables. For professional installations in public buildings, the combination of long service life, premium bare copper conductor, and enhanced fire safety makes this cable an excellent long-term investment that provides decades of reliable, safe operation.

Does LSZH cable cost more than standard PVC cable?

Yes, premium LSZH Dca cable with bare copper conductor typically costs more than standard PVC cable with copper clad steel due to two factors: the specialized LSZH compound with UV resistance and enhanced fire rating, and the premium bare copper conductor. However, for public buildings and safety-critical installations where LSZH and enhanced fire ratings are mandated by regulations, the additional cost is necessary for compliance. The investment is justified by: superior fire safety protecting lives and property; compliance with building codes and insurance requirements; better signal performance from the bare copper conductor; and long-term reliability. In applications where fire safety and signal quality are priorities, premium LSZH Dca cable is the professional choice regardless of cost considerations.

Can this cable use standard RG59 connectors?

Yes, despite the premium LSZH jacket, this cable maintains the standard RG59 outer diameter (6.10mm) and is fully compatible with all standard RG59 BNC connectors, F-connectors, and termination tools. The installation process and connector types are identical to standard PVC RG59 cables. The only differences are the internal conductor material (bare copper vs copper clad steel) which affects electrical performance, and the jacket material (UV LSZH vs PVC) which affects fire safety properties. Professional installers can use their familiar techniques and existing connector inventory, making this cable a direct replacement for standard RG59 in applications requiring enhanced fire safety and premium performance.
