1.5mm2 To 400mm2 Fire Resistant Cable NH-VV PVC Control Cable 0.6/1kV

NH-VV is a fire-resistant low-voltage power cable designed, according to relevant standards, to maintain circuit integrity and operate continuously for a period of time during fire exposure. It is commonly used in emergency and life-safety power circuits requiring continuous circuitry, such as emergency lighting feeders, fire pump power supplies, smoke exhaust fans, critical ventilation systems, and essential equipment that must maintain power supply during evacuation and firefighting. NH-VV typically uses copper conductors, is covered with PVC insulation and a PVC sheath, and integrates fire-resistant elements into the construction.

For cross-border sourcing, NH-VV is a practical and standards-compliant emergency circuit power cable when a PVC-sheathed construction is specified and the project budget requires a reliable and widely accepted solution.

Typical rated voltage: 0.6/1 kV

Please confirm the exact required rated voltage, fire resistance rating, and duration in your Bill of Quantities (BOQ).

• Emergency lighting feeders and distribution lines
• Fire pump power supply and critical pump room circuits
• Smoke exhaust and booster fan power circuits
• Emergency ventilation and critical HVAC (HVAC) gas supply lines
• Emergency elevators and critical building equipment (depending on the project)
• Power supply for critical switchboards and life safety distribution boxes

• Fixed installation in cable trays, conduits, trunking, risers, shafts, equipment rooms, and protected indoor pathways.

• 1C for high-current feeders and phase-separated installations
• 2C for dedicated single-phase emergency circuits
• 3C for three-phase circuits without a neutral wire (depending on the project)
• 4C for three-phase circuits with a neutral wire (common)
• 5C for three-phase circuits with a neutral wire and protection circuits (common)
• 3+1 and 3+2 are used in many market-standard feeder designs (depending on the project)

Availability depends on conductor grade and fire-resistant construction required by reference standards.

• Providing Fire-Resistant Circuit Continuity for Life Safety

  Designed to maintain power supply for a specified time during a fire, supporting evacuation, fire-fighting equipment, and essential services.

• Easy-to-Produce PVC Construction

  PVC insulation and PVC sheath construction are well-known and widely used by contractors, facilitating installation, termination, and maintenance.

• Cost-Effective Emergency Circuit Compliance Solution

  When the Bill of Quantities (BOQ) requires the use of PVC, the required fire resistance is provided without the need for more advanced Low Smoke Halogen-Free (LSZH) specifications.

• Wide Range of Sizes for Feeders and Distribution

  Supports cross-sections from small to large and multi-core configurations to meet the needs of various emergency power loads.

• A Reliable Choice for Public Buildings and Infrastructure

  Commonly used in hospitals, shopping malls, high-rise buildings, stations, and industrial sites where emergency power continuity is required.

1. Copper Conductor Production

   Copper is drawn and stranded to meet the resistance and flexibility requirements of the installation path.

2. Fire-Resistant Component Integration

   Fire-resistant layers are added according to required standards to form a critical structure that maintains circuit integrity in a fire environment.

3. PVC Insulation Extrusion

   PVC insulation layers of controllable thickness are used to meet dielectric performance requirements.

4. Cable and Molding

   For multi-core structures, the insulated cores are stranded in a controllable geometry; fillers and adhesives can be used to maintain shape and improve sheath quality.

5. PVC Outer Sheath Extrusion

   In fixed installations, a PVC sheath provides mechanical protection and improves path durability.

6. Routine Testing and Compliance Checks

   Typical checks include conductor resistance, insulation thickness, spark testing, voltage testing, dimensional verification, and continuity checks. Fire resistance verification is performed according to the required rating and standards.

Application:

Fire-resistant low-voltage distribution cable for emergency circuits

• When the project requires fire-resistant low-voltage power cables (with PVC sheath) to maintain emergency load circuit operation in the event of a fire, please select NH-VV cables.
• Please confirm the fire resistance duration and relevant standards in the tender documents.
• Select the number of cores based on the system design (neutral and protective circuit requirements).
• Select the cross-sectional area based on current, line length, grouping, ambient temperature, and allowable voltage drop.
• If the circuit requires low-smoke halogen-free performance, please select the LSZH fire-resistant cable specified in the project.

• What are the main uses of NH-VV?

  NH-VV is used for emergency low-voltage power circuits that must remain operational for a certain period during fire exposure, such as emergency lighting, fire pumps, and smoke exhaust fans. Specific applications must comply with project standards.

• What does NH usually stand for?

  NH usually stands for fire-resistant construction, designed to maintain circuit integrity during fire exposure. Specific testing methods and durations are specified by relevant standards.

• Is NH-VV the same as ordinary VV cable?

  No. NH-VV cables incorporate fire-resistant elements in their construction to ensure circuit integrity during a fire, unlike standard VV cables.

• Where are NH-VV cables typically installed?

  NH-VV cables are typically installed in protected fixed wiring, such as cable trays, conduits, risers, and equipment rooms, for emergency power distribution.

• Can NH-VV cables be used outdoors?

  Outdoor suitability depends on the PVC sheath formulation and environmental exposure. If UV and weather exposure are anticipated, please specify the environment so that appropriate sheathing and protection measures can be selected.

• What information is needed for an accurate quote?

  Fire resistance requirements and duration, conductor configuration, cross-sectional area, total length, required standards, packaging preferences, and destination.
