5 Core Flame Proof Cable ZC-VV22 PVC Armored Power Cable 0.6/1kV

ZC-VV22 is a low-voltage PVC-insulated, PVC-sheathed, steel-tape armored power cable designed for fixed installation routes requiring enhanced mechanical protection and superior flame retardancy. It is commonly used in underground conduits, trenches, cable corridors, and building inlets, locations where external pressure, backfill stress, or field handling risks are higher than standard indoor cable trays. In many market conventions, VV indicates PVC insulation and PVC sheath, 22 typically indicates steel-tape armor, while ZC is widely used to indicate the flame retardancy rating to ensure the safety of cable routes in projects.

For cross-border sourcing, ZC-VV22 is positioned as a practical and durable + flame-retardant low-voltage armored cable suitable for infrastructure, industrial sites, and building distribution applications where route protection requirements are high.

Typical rated voltage: 0.6/1 kV

Please confirm the exact flame retardancy rating required in your project standards and Bill of Quantities (BOQ).

• 1C for single-core feeder designs (project-specific)
• 2C for dedicated single-phase circuits
• 3C for three-phase circuits without a neutral (project-specific)
• 4C for three-phase circuits with a neutral (widely used)
• 5C for three-phase circuits with a neutral and protection (widely used)
• 3+1 and 3+2 for many commonly used feeder configurations (project-specific)

Availability depends on conductor grade, armor construction, and required standards.

• Steel tape armor provides pressure resistance and line protection. Steel tape armor construction is commonly used to improve the resistance to external pressure and mechanical stress in conduits, trenches, and protected underground lines.
• Flame retardant rating ensures safer installation. The ZC flame retardant rating helps limit the spread of flame along cable lines, thus improving safety in risers, corridors, and dense installation environments.
• PVC insulation and sheath for cost-effective performance. PVC is widely used in low-voltage distribution due to its practicality, economy, and ease of installation and termination.
• Suitable for Industrial and Infrastructure Lines Commonly used in building feeders, industrial power distribution, utility corridors, and fixed installations with high mechanical risk.
• Facilitates procurement for contractors and distributors Standard configurations and common sizes support repeat orders, inventory planning, and project delivery schedules.

• Underground conduit and trench power distribution
• Building feeders and main low-voltage power distribution lines
• Cable corridors and service tunnels with external pressure risks
• Industrial and utility lines requiring armor protection
• Fixed installation lines expected to experience high field handling stress

1. Copper Conductor Preparation Copper is drawn and stranded to the required grade to meet resistance targets and installation flexibility requirements.
2. PVC Insulation Extrusion PVC insulation is extruded with controlled thickness to ensure consistent dielectric properties.
3. Core Identification and Routing Cores are identified and routed according to the required number, using filler and binding tape as needed to maintain a stable geometry.
4. Side Layer Formation Side layers are laid to protect the core assembly and provide a smooth base for the armor layer.
5. Steel Strip Armor The steel strip is wound around the core in a controlled overlapping manner, primarily providing mechanical protection against compression and external pressure.
6. PVC Outer Sheath Extrusion The PVC outer sheath is used to improve line durability and protect the armor layer.
7. Routine Testing and Inspection Typical inspections include conductor resistance, insulation thickness, spark testing, voltage testing, dimensional verification, and sheath integrity checks. Flame retardancy verification is performed according to the required rating.

• When your project requires flame-retardant PVC armored low-voltage cables to ensure safer cable laying and stronger mechanical protection, please select ZC-VV22.
• Select the number of cores based on the power distribution scheme and neutral/PE requirements.
• Select the cross-sectional area based on current, laying length, ambient temperature, grouping, and allowable voltage drop.
• For laying in environments with high impact risk or special corrosive conditions, clearly define the laying conditions to ensure proper matching and protection design.
