Aluminum alloy 4*50 + 1 high-voltage wire and cable YJLHV. Power industrial engineering manufacturer. Batch supply of power cables. Starting from 100 meters.

I. Model and Structure (As you mentioned, “aluminum alloy 4*50 + 1 high-voltage wire and cable YJLHV”)
Model: YJLHV 4×50 + 1×25 (standard format)
Y: Polyethylene insulation
J: Cross-linked (XLPE, cross-linked polyethylene)
L: Aluminum / Aluminum alloy conductor
H: Aluminum alloy (AA8030/AA8000 series)
V: Polyvinyl chloride (PVC) outer sheath
4×50 + 1×25: 4 cores 50mm² + 1 core 25mm² (ground wire), aluminum alloy conductor
Voltage level: 0.6/1kV (low voltage), not high voltage; high voltage is generally 8.7/10kV, 26/35kV Structure
Conductor: Rare earth high-titanium aluminum alloy (AA8030), compact type, resistant to creep, greater flexibility than pure aluminum
Insulation: XLPE (cross-linked polyethylene), long-term working temperature 90℃
Filling / Wrapping: Ensures roundness and resistance to compression
Outer sheath: PVC (polyvinyl chloride), black, wear-resistant, weather-resistant, flame-retardant
Standards: GB/T 31840-2015 (aluminum alloy cable national standard), IEC 60502
II. Core parameters (national standard YJLHV 4×50+1×25)
Rated voltage: 0.6/1 kV
Conductor: Aluminum alloy AA8030, 4×50mm² (phase wire) + 1×25mm² (ground wire)
Long-term allowable working temperature: 90℃; Short-circuit temperature (≤5s): 250℃
Installation temperature: ≥0℃; Minimum bending radius: 15D (multi-core without armor)
Circuit current reference (air installation): Approximately 145–160A (specific to the manufacturer’s sample)
Weight: Approximately 1.8–2.0 kg/meter (about 40% lighter than the same specification copper cable)
Flame retardant grade: Regular ZC (C-level flame retardant), can be upgraded to ZB/ZA, fire-resistant (NH-YJLHV)
Certification: CCC compulsory certification (essential for national standards)
III. Applicable scenarios (preferred for industrial engineering)
Industrial plants: Workshop power distribution, production lines, fans, water pumps, large equipment power supply
Commercial / Residential: Residential areas / shopping malls main power supply, vertical shafts, underground garage power distribution
Infrastructure: Parks, logistics warehouses, photovoltaic / wind power, pipe racks, municipal power distribution
Advantages
Low cost: 40%–55% cheaper than the same specification copper cable (YJV 4×50+1×25)
Light weight: Saves installation effort, reduces labor costs by 20%–30%
Resistance to creep: Aluminum alloy conductor is more stable than pure aluminum, connection is reliable
Corrosion resistance: Suitable for humid, mild corrosive environments
