9501 300V LSZH Alternative Cable

What is 9501-300V LSZH Alternative Cable?

The 9501-300V LSZH Alternative Cable is an unarmoured, overall-screened low-voltage data and instrumentation cable featuring Class 2 stranded tinned copper conductors, PE insulation, an aluminium foil shield with a tinned copper drain wire, and a grey LSZH outer sheath complying with European EN 50575 CPR fire safety standards. It is designed for fixed signal, instrumentation control, and RS232 data transmission up to 300V where low signal distortion and comprehensive noise suppression are critical over long distances.

Engineered to resolve data dropouts and cross-talk interference in dense automated facilities, the cable pairs low-capacitance polyethylene insulation with an impervious aluminium foil screening layer. This structure isolates low-level electronic pulses from surrounding motor and drive electromagnetic radiation, while its halogen-free thermoplastic jacket produces no corrosive acidic vapors during a fire, safeguarding human life along egress corridors and preventing secondary corrosion damage to expensive switchboards and microelectronics.

9501-300V LSZH Alternative Cable Construction

• Conductor: 1 Pair 24 AWG (7/0.20mm) Class 2 stranded tinned copper conductors offering high electrical conductivity and resistance against surface oxidation.
• Insulation: Premium Polyethylene (PE) compound delivering low dielectric loss and high signal propagation stability.
• Pair Assembly: 1 twisted pair engineered to minimize internal inductive loop errors and signal phase shift.
• Screen / Shield: Overall Aluminium Foil (AL-Foil) providing 100% electrostatic coverage against electromagnetic interference.
• Drain Wire: Stranded tinned copper drain wire in direct contact with the foil screen for low-resistance grounding termination.
• Outer Sheath: Thermoplastic Low Smoke Zero Halogen (LSZH) compound offering flame retardancy and acid-free safety.
• Core Identification: Pair 1: Black and Red (with standardized pairing codes Pair 2: Black/White, Pair 3: Black/Green, Pair 4: Black/Blue).
• Sheath Colour: Grey.

Applications

Frequently Asked Questions

Q: Why is Polyethylene (PE) insulation preferred over PVC for RS232 and data applications?
A: Polyethylene exhibits a significantly lower dielectric constant and dissipation factor than standard PVC, ensuring lower signal attenuation and distortion over extended distances, which preserves pulse rise times in digital communications.

Q: What is the primary benefit of the AL-Foil screen and tinned copper drain wire?
A: The AL-Foil tape provides 100% electrostatic coverage to prevent external electromagnetic interference from corrupting micro-volt instrumentation signals, while the tinned drain wire allows fast, reliable grounding termination without unraveling wire braids.

Q: What life-safety advantages does the LSZH jacket provide during a building fire?
A: The LSZH jacket generates minimal smoke to maintain visual clarity in evacuation paths and releases zero acidic halogen fumes (such as hydrogen chloride), eliminating lethal inhalation risks and shielding precision electronics from airborne acid etching.

Q: What payment terms does Huadong Cable accept for international industrial export orders?
A: We accept standard international commercial payment terms including Telegraphic Transfer (T/T, 30% advance deposit with 70% balance against shipping documents) and 100% Irrevocable Letter of Credit (L/C) at sight.
