1.5mm² 6701B Cable (H07Z-K) LSZH Pink Class 5 Flexible 450-750V LSZH-1.5-PINK-1

The LSZH-1.5-PINK-1 is a 1.5mm² 6701B LSZH single core cable, also designated H07Z-K, supplied in pink with a 450/750V voltage rating in a 100m length. This flexible, Class 5 copper conductor panel wiring cable is designed for applications where low smoke zero halogen properties are critical to safety.

This 6701B LSZH cable is ideal for wiring switchgear, instrument panels, metering equipment and appliances, particularly in environments where smoke and toxic fumes arising in a fire could threaten life or damage sensitive equipment. Its cross-linked LSZH insulation provides excellent fire safety performance while maintaining the flexibility needed for neat, efficient installation in confined panel spaces.

Key Features

• Low Smoke Zero Halogen Insulation: Cross-linked LSZH (Type EI5) insulation minimises toxic fume and smoke emission during fire, protecting personnel and equipment in enclosed spaces.
• Class 5 Flexible Conductor: Plain annealed copper with 30/0.25mm stranding offers superior flexibility, making cable routing and termination within control panels significantly easier.
• 450/750V Voltage Rating: H07Z-K rated for reliable performance in higher voltage panel wiring and equipment applications.
• Wide Temperature Range: Operates from -15°C to +90°C, suitable for demanding industrial environments.
• Compact 3.4mm Diameter: With 0.7mm radial insulation thickness, the cable maintains a small footprint for trunking and conduit runs.
• Pink Identification: Distinct colour coding aids circuit identification and compliance with wiring schedules.
• 100m Supply Length: Convenient drum length for panel building and project work, reducing waste and cable joints.
• BASEC Certified: Independent third-party certification provides assurance of quality and compliance.

Applications

This 1.5mm² 6701B LSZH cable is suitable for internal wiring of appliances, switchgear panels, instrument panels and metering equipment. It is particularly specified for installations in public buildings, hospitals, transport infrastructure and data centres where fire safety regulations demand low smoke and halogen-free cable types. The approximate AWG equivalent of 16 AWG also makes it suitable for specifiers working to international standards. The minimum bending radius is 3 times the overall diameter.

Frequently Asked Questions

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

The conductor comprises 30 strands of 0.25mm plain annealed copper, giving it Class 5 flexibility.

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

The key difference is the voltage rating: H07Z-K (6701B) is rated 450/750V while H05Z-K (2491B) is rated 300/500V. Both share the same LSZH construction but the 6701B is specified where higher voltage ratings are required.

What is the overall diameter and minimum bending radius?

The approximate overall diameter is 3.4mm, giving a minimum bending radius of 10.2mm (3 × overall diameter).

Can this cable be used in fire-critical environments?

Yes — its LSZH insulation is tested to BS EN/IEC 60332-1-2 for flame propagation, BS EN 50267-2-1 for halogen content, and BS EN/IEC 61034-1 for smoke density.
