9844-SWA LSZH 600V Alternative Cable

What is 9844-SWA LSZH 600V Alternative Cable?

The 9844-SWA LSZH 600V Alternative Cable is an armoured, double-screened low-capacitance multi-pair data transmission cable featuring Class 2 stranded tinned copper conductors, PE insulation, an LSZH inner sheath, an AL-PET foil tape with a drain wire, a tinned copper wire braid (TCWB) screen, steel wire armour (SWA), and a grey LSZH outer jacket complying with EN 50575 CPR fire safety standards. It is designed for high-speed, noise-immune signal transmission up to 600V in industrial RS485 multi-drop communication buses, process automation architectures, and harsh outdoor plant environments.

Engineered to ensure signal fidelity under extreme electromagnetic and mechanical stresses, the cable features an exact 120-ohm characteristic impedance match and a 66% velocity of propagation. The dual AL-PET foil and braided tinned copper shielding architecture isolates delicate multi-drop differential telemetry from high-voltage motor and drive noise, while helical steel wire armour delivers high radial crush resistance and tensile strength for direct burial or exposed tray installations. The halogen-free thermoplastic outer jacket emits zero corrosive acid gases under fire exposure, safeguarding sensitive control electronics and maintaining clear evacuation routes in enclosed facilities.

9844-SWA LSZH 600V Alternative Cable Construction

• Conductor: 4 Pairs 24 AWG (7/0.20mm) Class 2 stranded tinned copper conductors offering superior conductivity and corrosion resistance.

Frequently Asked Questions

Q: What is the primary benefit of Steel Wire Armour (SWA) on the 9844 alternative cable?
A: Steel Wire Armour (SWA) provides high tensile strength and radial crush resistance, allowing the cable to be directly buried in underground plant trenches and routed through exposed outdoor raceways without requiring additional metallic conduit.

Q: Why does the cable combine an AL-PET foil screen with a TCWB braid?
A: The AL-PET foil provides 100% electrostatic coverage against high-frequency electromagnetic noise, while the tinned copper wire braid shields against low-frequency magnetic interference and provides enhanced mechanical strength.

Q: What life-safety advantages does the LSZH outer sheath provide compared to standard PVC?
A: The LSZH outer jacket 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 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.
