1. Official Name, Model Code & Standards

Full Name: 0.6/1kV Rare Earth High-Speed Aluminum Alloy Conductor XLPE Insulated Aluminum Interlocked Armoured Power Cable (Basic Type Without Outer Sheath) Commercial Model: MELHS; National Standard Model: YJLHS Compliance: GB/T 31840.1-2015, GB/T 29920, IEC 60502, consistent with North American AC90 specification无锡江南电...

Model Code Explanation

• MELH: Enterprise code for AA8030 rare earth aluminum alloy conductor

• YJ: XLPE cross-linked polyethylene insulation

• L: Aluminum alloy conductor

• H: Mark for rare earth iron-aluminum alloy

• S: Aluminum interlocking armour (no plastic outer sheath) Variant: WDZB-YJLHS = Class B1 LSZH flame retardant type

2. Internal Structure (Inner to Outer, No Outer Plastic Sheath)

1. Compact Stranded AA8030 Rare Earth Aluminum Alloy ConductorClass 2 shaped wire compact stranding minimizes internal gaps. It eliminates creep, terminal loosening and overheating defects of pure aluminum cables. For equal current capacity, its cross-section is 1.5 times copper cable while weight is only 50% of copper counterpart, featuring outstanding flexibility and stable connection under temperature cyclesTONG GUANG....

2. XLPE Insulation LayerMaximum continuous operating temperature 90℃, short-circuit withstand temperature 250℃ (≤5s); uniform insulation, low dielectric loss and water-tree resistance. LSZH insulation is optional for fire safety requirements.

3. Flame-Retardant Filler & Wrapping Buffer LayerDense eco-friendly filling ensures cable roundness, relieves mechanical stress and blocks longitudinal moisture penetration for dry indoor flame retardant needs.

4. 5000-Series Aluminum Interlocking Armour (Outermost Layer, No Outer Sheath)Continuous corrugated interlocked aluminum tape serves as the final protection:

• Non-magnetic material avoids eddy current loss and heat buildup during dense three-phase laying for higher energy efficiency;

• Ultra-flexible with bending radius only 7×cable outer diameter, suitable for sharp bends and vertical shaft wiring without numerous elbow fittings;

• Integrates compression resistance, impact resistance, rodent protection and basic electromagnetic shielding;

• Lighter than steel tape armour, allowing pipe-free & tray-free exposed installation indoors to greatly reduce auxiliary material and construction costs.

3. Core Performance Advantages

1. Lightweight & Flexible, Greatly Reduced Construction CostHalf the weight of copper cables with equal current capacity for easy transportation and wiring. Small bending radius adapts to complex wiring in machine rooms and shafts. Pipe/tray-free installation cuts bracket consumption and labor time by over 30%, ideal for indoor renovation projects广东欣意电....

2. No Eddy Current Loss, Higher Energy Efficiency for Dense DistributionNon-magnetic aluminum armour eliminates eddy current heat during dense three-phase laying, lowering voltage drop and power consumption for large-area industrial & residential distribution, superior to steel tape armored YJLHV22.

3. Excellent Creep Resistance & Permanent Connection SafetyRare earth optimized alloy structure resists thermal & mechanical deformation. Matched copper-aluminum bimetallic terminals guarantee stable connection without overheating under seasonal temperature variation.

4. Durable Service Life for Dry Indoor EnvironmentNon-aging inorganic insulation + metal armour delivers service life over 30 years under normal dry conditions. Dense passive oxidation film forms on armour surface for indoor corrosion resistance.

5. Integrated Multi-Function ProtectionCombines mechanical compression resistance, rodent proof, electromagnetic shielding and continuous PE earth conductor, simplifying power distribution systems.

6. Optional LSZH Class B1 Flame Retardant GradeWDZB-YJLHS releases little smoke and no toxic halogen gas during combustion, complying with fire codes for shopping malls, hospitals and office buildings安徽中青欣....
