About This Product

Dependable flame-retardant power distribution designed for industrial and commercial building wiring

Application Scenarios & Mainstream Selection

The ZC-YJV Class C flame-retardant, cross-linked polyethylene (XLPE) insulated power cable (featuring a PVC outer sheath and no armor) is a widely used fixed-installation power cable for building and industrial power distribution. It is the preferred choice for applications such as main feeders, floor-level distribution, branch circuits, and installations within cable trays or trenches—essentially any fixed-wiring scenario not subject to concentrated heavy mechanical pressure. Its Class C flame-retardant construction inhibits the spread of flames and possesses self-extinguishing properties, offering a significantly higher margin of fire safety compared to standard, non-flame-retardant YJV cables.

Core Technical Standards & Insulation Structure

The cable’s insulation structure complies with the GB/T 12706 standard, and its flame-retardant performance meets the requirements for combustion testing as specified in GB/T 19666-2019, “General Rules for Flame-Retardant and Fire-Resistant Electric Wires, Cables, or Optical Cables.” It has a rated voltage of 0.6/1 kV and is suitable for fixed installation indoors, in tunnels, or in cable trenches. As this model is unarmored, please select the steel-tape armored version (ZC-YJV22) if the cable is to be buried directly or subjected to external mechanical impact.

Full-Range Supply & Delivery Assurance

SinoPowerCable offers a full range of  ZC-YJV cables in various core counts and cross-sectional areas, manufactured using high-purity oxygen-free copper conductors and low-smoke, flame-retardant PVC materials. For cables with a cross-sectional area of up to 240 mm², the standard lead time is 12–20 days. All price quotes can be accompanied by factory test reports and relevant certification documents.

Cable Structure

Identical in geometry to standard YJV, but distinct in chemical properties during combustion.

    Conductor — Stranded Bare Copper (Class 2)

    High-purity annealed bare copper conductor per IEC 60228. Class 2 stranded configuration is standard for fixed installations, delivering stable electrical conductivity and excellent mechanical flexibility for building wiring and cable tray routing.

    Insulation — Cross-Linked Polyethylene (XLPE)

    Dry-cured XLPE insulation providing a maximum continuous conductor operating temperature of 90°C and 250°C under short-circuit conditions. Offers exceptional dielectric strength, thermal endurance, and moisture resistance for reliable power transmission.

    Filler & Binding Tape — Flame-Retardant Material

    Non-hygroscopic polymer filler fills the interstices between cores to maintain a circular and compact cable geometry. High-performance binding tape secures the core assembly and assists in retarding flame propagation along the cable axis.

    Outer Sheath — Flame-Retardant PVC (Class C)

    Extruded flame-retardant PVC outer sheath formulated to meet GB/T 19666 Class C fire performance standards, effectively suppressing flame spread and providing self-extinguishing capabilities. Acts as the primary mechanical and environmental protection;

    Frequently Asked Questions

    BTTZ is the classic rigid mineral-insulated cable: copper conductor, magnesium oxide powder insulation, copper tube outer sheath, all drawn together. Invented 1930s, still the gold standard but heavy, expensive, rigid, and prone to moisture absorption at cut ends. BBTRZ replaces the MgO powder with extruded mineral compound and the copper tube with LSZH polyolefin — flexible, drum-length, cheaper, easier to install. BTTRZ keeps the LSZH outer jacket but adds back a laser-welded seamless copper tape sheath underneath for hermetic moisture sealing and continuous earth path. Cost ranking: BBTRZ < BTTRZ < BTTZ.

    Is BBTRZ a real mineral insulated cable, or just “mineral insulated” in name?
