Asl 1.5mm Single Cable Green-Roll

Asl 1.5mm Single Cable Green: Dedicated Earthing Conductor

Single-core cables are fundamental building blocks in electrical installation, used extensively for internal wiring within buildings, control panels, and equipment. This 1.5mm² single cable features a stranded copper conductor insulated with high-quality green PVC, specifically intended for protective earthing applications.

The green insulation colour provides immediate visual identification of the conductor’s function as a protective earth, ensuring compliance with wiring regulations and enhancing safety during installation and maintenance . The “Asl” designation identifies this specific product range, manufactured to meet relevant British and international standards for electrical cables.

Asl 1.5mm Single Cable Green: Key Specifications

Asl 1.5mm Single Cable Green: Conductor Construction

The conductor is manufactured from plain annealed copper, chosen for its excellent electrical conductivity and ductility . The stranded construction consists of multiple fine copper wires twisted together, typically around 7 or 16 strands depending on the specific manufacturer.

This stranding offers several advantages:

• Flexibility: Easier to bend and route through conduit and trunking compared to solid conductors

• Vibration Resistance: Less prone to work-hardening and breaking in applications subject to movement

• Termination: Provides better contact area in screw terminals

• Handling: Easier to strip and prepare for connection

Asl 1.5mm Single Cable Green: PVC Insulation

The green PVC insulation serves multiple critical functions:

Electrical Insulation: Provides excellent dielectric strength, preventing electrical leakage and ensuring safe isolation of the protective conductor where required.

Mechanical Protection: Protects the copper conductor from abrasion, impact, and damage during installation and service.

Colour Identification: The green insulation provides clear visual identification as a dedicated protective earth conductor . This is distinct from green/yellow striped cable which is also used for earthing, but plain green is specified in some applications.

Environmental Resistance: PVC offers good resistance to moisture, chemicals, and UV exposure (when installed within appropriate containment).

Temperature Rating: Rated for continuous operation up to 70°C, suitable for normal operating conditions in buildings.

Asl 1.5mm Single Cable Green: Applications

This versatile single-core cable is suitable for numerous applications, particularly where protective earthing is required:

Earthing Conductors: Used as protective earth conductors in lighting circuits, power circuits, and final sub-circuits where a separate earth wire is required.

Supplementary Bonding: Ideal for supplementary bonding connections in bathrooms, kitchens, and other locations requiring additional protection.

Control Panels: Used for internal wiring of control panels, distribution boards, and electrical enclosures where earth connections are needed.

Lighting Circuits: Suitable for switch drops and wiring where an earth conductor is required for Class I lighting fittings.

Conduit Wiring: Ideal for drawing into conduit systems where individual insulated earth conductors are required.

Switch Wiring: Provides earth connections between switches, outlets, and accessories.

Extension Wiring: Suitable for extending circuits where an earth conductor is required within appropriate mechanical protection.

Asl 1.5mm Single Cable Green: Importance of Correct Earthing

The green insulation colour is internationally recognised for protective earthing conductors. Using correctly identified cables is essential for:

Safety: Ensures that anyone working on the installation can immediately identify earth conductors, reducing the risk of accidental disconnection or incorrect termination.

Compliance: Wiring regulations require protective conductors to be identified by the colour green or green/yellow.

Testing and Inspection: Makes testing and verification of earthing systems straightforward and reliable.

Maintenance: Facilitates future modifications and fault-finding by providing clear visual identification.

Asl 1.5mm Single Cable Green: Current Ratings

The current-carrying capacity depends on installation method:

These ratings are typical and may vary based on ambient temperature, grouping with other cables, and specific installation conditions. Reference should be made to the current edition of wiring regulations for final sizing.

Asl 1.5mm Single Cable Green: Installation Considerations

Conduit and Trunking: This cable is designed for installation within conduit, trunking, or other approved containment systems that provide mechanical protection. It is not suitable for direct burial or outdoor use without additional protection.

Bending Radius: The minimum bending radius should be observed to prevent damage to the conductor or insulation. Typically 3 times the cable diameter.

Stripping: Use appropriate cable stripping tools to remove insulation without nicking or damaging the copper conductor strands.

Termination: Ensure conductors are correctly terminated in suitable terminals, with no stray strands exposed. The correct torque should be applied for the terminal type.

Derating: When multiple cables are bunched together, derating factors apply to the current-carrying capacity. Consult wiring regulations for guidance.

Colour Identification: Green insulation is used specifically for protective earth conductors. Do not use green for live or neutral connections.

Asl 1.5mm Single Cable Green: Voltage Rating

The 450/750V voltage rating indicates:

• 450V: Voltage to earth (phase to neutral/earth)

• 750V: Voltage between phases

This makes the cable suitable for standard single-phase and three-phase installations up to 750V, covering all normal domestic and commercial applications.

Asl 1.5mm Single Cable Green: Quality and Compliance

This cable is manufactured to meet rigorous international standards:

• BS 6004: British Standard for PVC-insulated cables for electric power and lighting

• HD 21: Harmonised European standard for PVC-insulated cables

• CE Marking: Indicates compliance with relevant European directives

• RoHS Compliance: Free from hazardous substances

• KS 453-2: Complies with applicable national standards where relevant

Asl 1.5mm Single Cable Green: Storage and Handling

Store the cable in a clean, dry environment away from direct sunlight and chemicals that could degrade the PVC insulation. Coils should be stored flat to prevent distortion. When handling, avoid sharp bends and ensure the cable is not kinked or twisted, which could damage the insulation or conductor.

Asl 1.5mm Single Cable Green: Availability

This cable is typically available in various lengths:

• Per metre: Cut to your exact requirements for small projects

• 100m coils: Standard reel size for regular use

• 500m drums: For contractors and larger installations

When ordering cut lengths, you will receive one continuous piece of cable, not multiple sections.

When installed correctly within appropriate containment and in accordance with current wiring regulations, Asl 1.5mm Single Cable Green provides a safe, reliable, and clearly identifiable earthing solution for residential, commercial, and industrial electrical installations.
