9504-300V LSZH Alternative Cable

What is 9504-300V LSZH Alternative Cable?

The 9504-300V 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 eliminate data transmission loss and cross-talk interference in complex multi-channel automation architectures, the cable combines low-capacitance polyethylene insulation with an impermeable aluminium foil screening shield. This architecture isolates delicate digital and analogue pulses from neighboring variable frequency drives and power equipment, while its halogen-free outer jacket ensures zero corrosive acid emissions during thermal incidents, preserving clear escape routes and shielding expensive control hardware from secondary chemical damage.

9504-300V LSZH Alternative Cable Construction

• Conductor: 4 Pairs 24 AWG (7/0.20mm) Class 2 stranded tinned copper conductors providing high electrical conductivity and resistance to oxidation.
• Insulation: Low-dielectric Polyethylene (PE) compound delivering minimal capacitance and low transmission attenuation.
• Pair Assembly: 4 twisted pairs laid up to minimize internal crosstalk and electromagnetic distortion.
• Screen / Shield: Overall Aluminium Foil (Al-Foil) screen offering 100% electrostatic coverage against high-frequency electromagnetic interference.
• Drain Wire: Continuous tinned copper drain wire in intimate contact with the foil screen for low-resistance grounding termination.
• Outer Sheath: Thermoplastic Low Smoke Zero Halogen (LSZH) compound delivering flame-retardant, acid-free safety.
• Core Identification: Pair 1: Black and Red; Pair 2: Black and White; Pair 3: Black and Green; Pair 4: Black and Blue.
• Sheath Colour: Grey.

Frequently Asked Questions

Q: Why is Polyethylene (PE) insulation preferred over standard PVC for 4-pair RS232 communication?
A: Polyethylene possesses a significantly lower dielectric constant and dissipation factor than standard PVC, which reduces capacitive signal attenuation, prevents waveform distortion over long distances, and maintains high-speed digital pulse integrity.

Q: What is the operational function of the Al-Foil screen and tinned copper drain wire?
A: The aluminium foil provides 100% electrostatic shielding against external electromagnetic fields, while the continuous tinned copper drain wire ensures reliable and effortless ground termination without unbraiding fine wires.

Q: What protection does the LSZH sheath offer in public or enclosed industrial spaces?
A: The LSZH compound generates low smoke density to maintain visibility during fire egress and emits zero acidic halogen fumes, protecting both human respiratory systems and sensitive electronics from corrosive acid damage.

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, with 30% advance deposit and 70% against shipping documents) and 100% Irrevocable Letter of Credit (L/C) at sight.
