Key words:
1. Product Overview
Low Voltage Power Cable (Low Voltage Power Cable) usually refers to cables with rated voltage 0.6/1kV and below, which are used for fixed laying in the power system with AC 50Hz and rated voltage not exceeding 1kV, to transmit and distribute electric energy. Widely used in construction, municipal, industrial, mining, rail transportation and other fields.
2. Product structure
Low-voltage power cables are composed of multi-layer materials to ensure electrical conductivity, insulation and mechanical protection:
Conductor:
Material: High purity oxygen-free copper (T1/T2) or aluminum alloy (AA8000 series) in accordance with IEC 60228.
Type: Multi-stranded stranded (Class 2/5) or single core (Class 1) for improved flexibility and resistance to bending.
Insulation:
Material: polyvinyl chloride (PVC), cross-linked polyethylene (XLPE) or ethylene propylene rubber (EPR).
Characteristics: Heat-resistant (70℃~90℃), flame-retardant, chemical-resistant.
Filler layer (multi-core cable): non-hygroscopic material (e.g. PP rope) to maintain roundness.
Inner sheath (optional): PVC or PE to enhance internal protection.
Armor layer (optional):
Steel Tape Armor (STA): pressure resistant, suitable for direct burial.
Steel wire armor (SWA): tensile, for mine or underwater.
Outer sheath:
Material: PVC (weather-resistant), PE (moisture-proof), LSZH (low-smoke halogen-free, flame retardant).
Color: black/gray (standard), can be customized.
3. Main types
VV/VLV: Copper core/Aluminum core PVC insulated PVC sheathed cable (non-armored).
YJV/YJLV: copper core/aluminum core XLPE insulated PVC sheathed cable (high temperature resistant 90℃).
NH-VV: fire-resistant type, mica tape wrapped conductor, maintained energized during fire.
ZC-YJV: Flame-retardant grade C, passed GB/T 18380 flame-retardant test.
WDZ-YJY: Halogen-free and low smoke, environmentally friendly, suitable for crowded places.
4. Technical parameters
Voltage level: 0.6/1kV, 300/500V.
Conductor cross-section: 1.5mm²~1000mm² (single-core or multi-core: 2~5 cores, including 3+1, 4+1, etc.).
Bending radius: ≥10×cable outer diameter (non-armored) or ≥15×(armored).
Working temperature:
PVC insulation: -15℃~70℃; XLPE insulation: -40℃~90℃.
Laying method: direct burial, pipe penetration, bridge, cable trench, etc.
5. Core performance
Electrical performance: pass partial discharge, industrial frequency withstand voltage test (3.5kV/5min).
Mechanical properties: tensile, compressive, wear-resistant (armored models are better).
Environmental adaptability:
Waterproof: IP68 rating (special model).
UV Resistance: Suitable for outdoor exposure.
Oil/acid/alkali resistance: Specialized for chemical occasions.
6. Certification Standards
International: IEC 60502, BS 5467, UL 1072.
Domestic: GB/T 12706, JB/T 8734.
Industry: Flame retardant (GB/T 19666), fire resistant (GB/T 19216).
7. Application Scenarios
Building power distribution: building trunk lines, lighting circuits.
Industrial equipment: motor, inverter, production line power supply.
Infrastructure: subways, airports, tunnels (flame retardant/low smoke required).
New energy: photovoltaic power stations, wind farms within the low-voltage connection.
8. Advantageous features
Safe and reliable: strict process control, low failure rate.
Long life: XLPE insulation life of more than 30 years.
Customization: Flame retardant A/B/C grade, termite proof, rodent bite proof and other special requirements are available.
