Product Overview

The DL Series Aluminium Cable Lugs are low-voltage terminal components designed for secure, low-resistance connections between aluminum cables and electrical equipment (e.g., terminal blocks, circuit breakers, busbars). Manufactured from high-purity aluminum (AL≥99.5%, typically alloy 1350), they ensure minimal electrical resistance, reducing voltage drop and heat generation at connection points. The series covers cable cross-sectional areas from 10mm² (DL-10) to 300mm² (DL-300), with precise dimensional tolerances (e.g., ±0.5mm for φ, ±2mm for length) to ensure compatibility with standard cables and equipment. Key design features include a seamless barrel (for cable crimping) and a flat palm (with precision-drilled bolt holes), delivering mechanical robustness and electrical reliability.

Key Features

High-Conductivity Material

99.5% pure aluminum ensures excellent electrical conductivity, meeting low-voltage (LV) power system requirements. The material also offers light weight and cost-effectiveness, especially for large cable sizes (e.g., DL-300 for 300mm² cables).

Two-Part Robust Construction

• Barrel: Seamless cylindrical section accepts stripped cable ends; crimping creates a cold-welded, gas-tight connection that resists vibration and corrosion.

• Palm: Flat tongue with precision-drilled holes (e.g., M8/M10 for DL-300) ensures secure bolting to equipment, preventing loose connections.

Durability & Corrosion Resistance

One-piece forged construction enhances resistance to mechanical stress, while the aluminum surface resists oxidation—suitable for indoor/outdoor applications (e.g., industrial panels, outdoor substations).

Standardized Sizing

Clear correlation between model number and cable cross-sectional area (e.g., DL-70 for 70mm² cables) simplifies product selection, reducing compatibility errors.

Scenario-Specific Solutions

Industrial Electrical Panels

In factories or manufacturing facilities, DL lugs connect incoming/outgoing feeder cables to distribution boards. The low-resistance connection prevents overheating, ensuring safe operation of motor control centers and automation systems.

Power Distribution Systems

Substations and switchgear use DL lugs to terminate LV cables (e.g., grounding conductors, feeder lines). The gas-tight crimping ensures long-term reliability, reducing maintenance checks.

Renewable Energy Installations

In solar farms or wind turbines, DL lugs connect cables from panels/turbines to inverters or LV combiner boxes. Their light weight eases installation in elevated or tight spaces (e.g., solar racking).

Grounding/Earthing Systems

For building or industrial grounding, DL lugs provide a robust connection between grounding conductors and earth bars. The corrosion-resistant design ensures consistent grounding performance, critical for electrical safety.

Technical Support

• Crimping Guidance: 4-step crimping process (prepare lug & wire → insert wire into barrel → crimp with specialized pliers → inspect connection) provided in manuals, with recommended crimping tool specifications.

• Dimensional Documentation: Detailed size tables (for all models) include φ, D, d, L, L1, and W dimensions, aiding cable/equipment matching.

• Compliance Testing: Each batch undergoes conductivity testing and mechanical strength checks (e.g., pull-out force for crimped connections) to meet LV standards.
