NHVV22 Cable
NHVV22 Cable: Engineered for Robust and Reliable Power Transmission
In demanding industrial and infrastructural applications, reliable power transmission is non-negotiable. The NHVV22 Cable stands as a premier solution, meticulously designed to deliver exceptional performance, durability, and safety under challenging conditions. This armored power cable is the backbone of critical operations, from heavy industrial plants to extensive underground distribution networks.
The NHVV22 is a copper conductor, PVC insulated, steel wire armored, and PVC sheathed cable. This specific construction provides a formidable defense against mechanical stress, corrosion, and environmental hazards, ensuring long-term operational integrity where standard cables would fail.
Core Features and Key Advantages
- Superior Mechanical Protection: The galvanized steel wire armor (SWA) offers robust resistance against crushing, impact, and rodent damage, making it ideal for direct burial and exposed installations.
- Enhanced Safety & Durability: PVC insulation and sheathing provide excellent resistance to moisture, acids, alkalis, and atmospheric degradation, ensuring safe operation and an extended service life.
- High Temperature Resistance: Rated for continuous operation at conductor temperatures up to 70°C, suitable for a wide range of ambient conditions.
- Excellent Electrical Properties: Designed for efficient power distribution with low dielectric losses, ensuring stable voltage transmission.
- Versatile Application Scope: Perfect for fixed installations in indoor, outdoor, underground, and cable duct environments. Widely used in power networks, industrial projects, and infrastructural development.
Detailed Technical Specifications
The following table outlines the standard construction and technical parameters of the NHVV22 Cable:
| Component | Material / Specification | Key Property / Standard |
|---|---|---|
| Conductor | Plain annealed copper, stranded (Class 2) | High conductivity, flexibility |
| Insulation | Polyvinyl Chloride (PVC) | Type TI, Rated for 70°C |
| Inner Sheath (Bedding) | PVC | Provides cushioning over armor |
| Armor | Galvanized Steel Wire (GSWA) | Mechanical protection |
| Outer Sheath | Polyvinyl Chloride (PVC) | Type ST, Grey or Black, rated for 70°C |
| Voltage Rating | 0.6/1 kV | U0/U |
| Standards Compliance | IEC 60502-1, BS 6346, SANS 1507-3 | |
Standard Sizing and Current Ratings
Available in a comprehensive range of core configurations and cross-sectional areas to meet diverse project requirements.
| Number of Cores | Nominal Cross-Sectional Area (mm²) | Approximate Overall Diameter (mm) | Approximate Weight (kg/km) | Rated Current in Air (A)* |
|---|---|---|---|---|
| 2 Core | 1.5 - 400 | 12.5 - 58.5 | 280 - 11000 | 20 - 630 |
| 3 Core | 1.5 - 400 | 13.0 - 61.5 | 320 - 12500 | 18 - 560 |
| 3.5 Core | 25 - 400 | 22.0 - 65.5 | 700 - 14000 | Refer to 4-core |
| 4 Core | 1.5 - 400 | 14.0 - 66.5 | 360 - 15000 | 16 - 500 |
*Current ratings are indicative for cables laid in air at an ambient temperature of 30°C. Consult engineering tables for specific installation conditions (buried, grouped, etc.).
Installation and Application Guidelines
The NHVV22 cable is designed for fixed installations. For direct burial, ensure a trench depth of at least 0.7 meters in non-traffic areas and 1.0 meter under roads. A layer of fine sand or screened soil is recommended as bedding below and above the cable to protect the sheath. In cable ducts, ensure proper sizing to avoid excessive pulling tension and allow for heat dissipation. The minimum bending radius during installation should be 12 times the overall cable diameter for armored cables.
Its primary applications include:
- Main and sub-main power distribution in industrial complexes.
- Underground power supply networks for residential and commercial developments.
- Feeder circuits for heavy machinery, pumps, and compressors.
- Power supply in environments with high risks of mechanical damage.
- Infrastructure projects like tunnels, water treatment plants, and mining operations.
