Z1O-YMz1Kas mbzh (LSZH) Cable

What is Z1O-YMz1Kas mbzh (LSZH) Cable?

The Z1O-YMz1Kas mbzh (LSZH) cable is a Dutch-standard, low-voltage (0.6/1kV) armoured halogen-free power cable accredited under KEMA K42C-1-5 and European harmonised standard HD-604-5-C. It is specifically engineered for heavy industrial distribution networks, direct underground burial, and routing in environments subject to severe mechanical compaction and physical stress.

Featuring XLPE insulation rated for continuous operation up to +90°C, the cable provides exceptional electrical dielectric strength and current-carrying capability. Its Galvanized Steel Wire Braid (GSWB) armour and tinned copper drain wire ensure robust mechanical impact protection and low-resistance earth fault grounding, while the dual HFFR bedding and outer jacket inhibit vertical flame spread per EN 60332-3-24 Category C without emitting toxic halogen acid fumes or dense smoke.

Z1O-YMz1Kas mbzh (LSZH) Cable Construction

• Conductor: High-purity plain annealed copper; Class 1 solid copper or Class 2 stranded copper conforming to European standards.
• Insulation: Cross-Linked Polyethylene (XLPE) compound providing high thermal overload endurance up to +90°C.
• Bedding / Filler: Halogen-free flame-retardant (HFFR) compound filler maintaining a compact circular core profile.
• Armour / Braiding: Galvanized Steel Wire Braid (GSWB) delivering high mechanical impact resistance and tensile protection.
• Drain Wire: Continuous tinned copper drain wire in direct contact with the braid for fast, reliable grounding.
• Outer Sheath: Heavy-duty halogen-free flame-retardant (HFFR) thermoplastic compound.
• Core Identification: Color-coded cores matching European harmonised low-voltage wiring conventions.
• Sheath Colour: Industrial Grey.

Applications

Z1O-YMz1Kas mbzh (LSZH) cables are engineered for primary and secondary low-voltage power networks requiring enhanced mechanical protection and non-toxic fire performance:

• Direct Underground Burial: Buried directly into soil trenches and subterranean service routes subject to backfill compaction and ground shifting.
• Industrial Facilities & Plants: Heavy manufacturing facilities, refineries, chemical plants, and processing depots where mechanical compulsion occurs.
• Underground Service Ducts: Hauled through civil utility ducts, outdoor concrete trenches, and service tunnels.
• High-Safety Infrastructure: Utility networks, transport hubs, and substations complying with EN 50575 CPR and zero-halogen fire safety regulations.

Frequently Asked Questions

Q: Is Z1O-YMz1Kas mbzh cable suitable for direct underground burial?
A: Yes, unlike unarmoured YMz1K cables, Z1O-YMz1Kas mbzh is specifically engineered with GSWB armour and a durable HFFR jacket, making it suitable for direct underground burial and areas where mechanical compulsion is present.

Q: What is the primary role of the Galvanized Steel Wire Braid (GSWB) and tinned copper drain wire?
A: The GSWB provides robust mechanical impact protection and rodent resistance, while the continuous tinned copper drain wire ensures reliable electrical continuity for earth fault current drainage.

Q: What is the significance of the KEMA K42C-1-5 accreditation?
A: Testing and accreditation by KEMA Laboratories in the Netherlands certifies that the cable complies with stringent European performance, material safety, and fire retardancy standards for critical infrastructure.

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