1.5mm² 6701B Cable (H07Z-K) LSZH Green/Yellow Class 5 Flexible 450-750V LSZH-1.5-GRN-YEL-1

The LSZH-1.5-GRN-YEL-1 is a 1.5mm² 6701B LSZH cable (H07Z-K) with green/yellow identification, supplied in a 100m length — a Class 5 flexible single-core panel wiring cable rated at 450/750V.

This 1.5mm² 6701B LSZH cable is designed for internal wiring of appliances, switchgear, instrument panels, and metering equipment where low smoke zero halogen properties are essential. Its green/yellow colour makes it ideal for earth conductor identification. The cross-linked LSZH insulation ensures that in a fire situation, smoke and toxic fume emissions are minimised, helping to protect life and sensitive equipment.

Key Features

• 1.5mm² Class 5 Flexible Conductor: Plain annealed copper with 30/0.25mm stranding provides excellent flexibility for routing through panels and tight enclosures.
• LSZH Cross-Linked Insulation (Type EI5): Produces minimal smoke and zero halogen gases during a fire, critical in enclosed or occupied spaces.
• 450/750V Voltage Rating (H07Z-K): Suitable for higher voltage equipment wiring applications compared to H05Z-K alternatives.
• Temperature Range -15°C to +90°C: Performs reliably across a wide operating range, suitable for demanding industrial environments.
• Approx. 3.4mm Overall Diameter: Compact profile with 0.7mm radial insulation thickness, allowing efficient cable management in dense installations.
• Green/Yellow Identification: Standard earth/protective conductor colour coding to BS EN 50525-3-41.
• 100m Reel: Convenient supply length for panel building and equipment wiring projects.
• Approximate 16 AWG Equivalent: Useful cross-reference for internationally specified projects.

Applications

This 6701B LSZH cable is suited for wiring within control panels, switchgear enclosures, instrument panels, and metering equipment. Its green/yellow colour coding makes it the standard choice for protective earth conductors. The LSZH properties make it particularly important in environments where smoke and toxic fumes arising in a fire could threaten life or damage sensitive equipment — such as public buildings, transport infrastructure, data centres, and industrial control rooms. The Class 5 flexible construction eases installation in congested panels and equipment.

Frequently Asked Questions

What is the conductor stranding of 1.5mm² 6701B LSZH cable?

The conductor comprises 30 strands of 0.25mm plain annealed copper (30/0.25mm), giving it Class 5 flexible characteristics.

What is the difference between 6701B (H07Z-K) and 2491B (H05Z-K) cable?

Both share the same LSZH construction and standards, but the 6701B (H07Z-K) is rated at 450/750V whereas the 2491B (H05Z-K) is rated at 300/500V, making the 6701B suitable for higher voltage equipment wiring.

What is the minimum bending radius for this cable?

The minimum bending radius is 3 times the overall diameter — approximately 10.2mm for this 1.5mm² size.

Can this cable be used outdoors?

This cable is designed for internal panel and equipment wiring applications. It is not intended for outdoor or direct burial use.
