8444NH Multi-Conductor Cable

What is 8444NH Multi-Conductor Cable?

The 8444NH Multi-Conductor Cable is a low-voltage, unscreened multi-conductor signaling cable featuring Class 2 stranded tinned copper conductors, polypropylene (PP) insulation, and a flame-retardant low smoke zero halogen (LSZH) outer jacket complying with UL 1685 FT4 and UK AWM 21307 standards. Operating at a 300V voltage rating, it is engineered for general-purpose instrumentation, security monitoring, audio lines, and low-speed data communication in modern commercial and industrial facilities.

Designed with a compact, unscreened profile, this cable facilitates rapid routing through conduit, trunking, and containment systems where high physical flexibility is required. The combination of low-dielectric polypropylene insulation and a halogen-free thermoplastic jacket ensures stable signal characteristics while preventing toxic halogen gas release during fire incidents, supporting life-safety compliance in public and commercial buildings.

Frequently Asked Questions

Q: What is the primary benefit of Polypropylene (PP) insulation in 8444NH?
A: Polypropylene offers a lower dielectric constant and lower mutual capacitance compared to standard PVC, resulting in reduced signal attenuation and better electrical transmission stability across instrumentation loops.

Q: How does the LSZH outer sheath enhance building safety?
A: The Low Smoke Zero Halogen (LSZH) jacket emits minimal non-toxic smoke and zero corrosive halogen acid gases during a fire, preserving visibility along evacuation routes and protecting sensitive electronic equipment from acidic damage.

Q: Can 8444NH cable be installed outdoors or directly underground?
A: 8444NH is an unscreened and unarmoured indoor cable; external or underground installations require routing inside enclosed protective conduits or cable containment systems.

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