9842-600V LSZH Alternative Cable

What is 9842-600V LSZH Alternative Cable?

The 9842-600V LSZH Alternative Cable is an unarmoured, double-screened low-capacitance multi-pair data transmission cable featuring Class 2 stranded tinned copper conductors, PE insulation, an Al/PET foil with a drain wire, a tinned copper wire braid (TCWB) screen, and a grey LSZH outer jacket complying with EN 50575 CPR fire safety standards. It is designed for noise-immune, high-speed signal and data transmission up to 600V in industrial RS485 serial fieldbus networks requiring superior noise suppression in high-density control environments.

Engineered to ensure uncorrupted signal integrity under demanding electromagnetic operating conditions, the cable combines low-loss polyethylene core insulation with dual-layer Al/PET foil and braided tinned copper shielding to isolate delicate differential signals from high-power machinery noise. Its halogen-free outer jacket emits zero corrosive acidic gases in fire conditions, preserving clear escape routes and protecting sensitive control room hardware from secondary chemical damage in enclosed public or commercial buildings.

9842-600V LSZH Alternative Cable Construction

• Conductor: 2 Pairs 24 AWG (7/0.20mm) Class 2 stranded tinned copper conductors offering superior conductivity and corrosion resistance.
• Insulation: Low-dielectric Polyethylene (PE) compound delivering low mutual capacitance and minimal signal attenuation.
• Pair Assembly: 2 twisted pairs laid up to suppress intra-cable crosstalk and ensure balanced differential communication.
• Screen / Shield: Double screening system consisting of an Aluminium/Polyester foil (Al/PET) tape providing 100% electrostatic coverage plus an overall Tinned Copper Wire Braid (TCWB) for maximum magnetic interference immunity.
• Drain Wire: Stranded tinned copper drain wire for rapid, low-resistance ground bonding.
• Outer Sheath: Thermoplastic Low Smoke Zero Halogen (LSZH) compound delivering flame-retardant, acid-free safety.
• Core Identification: Pair 1: Blue/White and White/Blue; Pair 2: Orange/White and White/Orange.
• Sheath Colour: Grey.

Frequently Asked Questions

Q: Why is a low mutual capacitance important in multi-pair RS485 instrumentation cables?
A: Low mutual capacitance reduces signal attenuation and distortion across extended cable runs, ensuring that high-speed digital pulses maintain their waveform integrity in long-distance fieldbus topologies.

Q: What is the operational benefit of combining an Al/PET foil screen with a TCWB braid?
A: The Al/PET tape provides 100% physical coverage against high-frequency electrostatic noise, while the tinned copper braid offers low-frequency magnetic shielding and high mechanical strength.

Q: What life-safety benefits does the LSZH outer sheath provide compared to standard PVC?
A: The LSZH outer sheath emits minimal non-toxic smoke and zero corrosive halogen acid gases during combustion, preserving emergency escape visibility and preventing secondary acid damage to sensitive control room electronics.

Q: What commercial payment terms does Huadong Cable Group offer for export contracts?
A: We provide standard international commercial 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 for engineering procurement contractors and overseas distributors.
