Electrical cable LGYDY LGY 1x120 mm² black 450/750V single-core power conductor

LGYDY LGY 1x120 mm² black electrical cable is a single-core power conductor designed for low-voltage distribution at 450/750V. The cable features a 120 mm² copper conductor cross-section and a black insulating sheath suitable for fixed installations and protected routing in commercial, industrial, and infrastructure projects that require high current capacity. It is intended for heavy-current applications such as feeders, main lines and connection points where a single-core power conductor is preferred.

Advantages

The single-core design provides straightforward routing and termination for feeders and main power lines. With a large conductor cross-section, the cable supports high current carrying capacity and reduced voltage drop over long runs. The 450/750V insulation rating makes the cable appropriate for standard low-voltage systems, while the black sheath offers basic protection against mechanical abrasion and simplifies identification in multi-cable installations.

Suitable for

• Feeder lines and main distribution circuits in commercial and industrial sites
• Fixed wiring in switchgear rooms and power panels
• Connection of transformers, motors and large loads requiring a single-core conductor
• Protected routing in cable trays, conduits and dedicated ducts

Key specifications

• Conductor cross-section: 120 mm² (single-core)
• Rated voltage: 450/750 V
• Sheath color: black
• Intended use: fixed installation and protected routing
• Application class: heavy-current / high current capacity

How to use

Install the LGYDY 1x120 mm² cable in accordance with local electrical codes and project wiring diagrams. Use appropriate lugging, crimping or bolted terminations rated for 120 mm² conductors, and ensure connections are tightened to specified torque values. Route the cable in trays, conduits or ducts designed for single-core power conductors and provide mechanical protection where exposure to damage is possible. Verify phase identification and perform insulation and continuity tests before energizing the circuit.

Usage recommendations

Choose installation accessories (lugs, heat-shrink, gland entries) sized for 120 mm² conductors and confirm compatibility with the cable sheath material. For long runs, check voltage drop and, where necessary, increase conductor cross-section or apply parallel runs per applicable standards. Follow local regulations for current rating, derating factors and ambient temperature corrections.
