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

The LSZH-1.5-WHITE-1 is a 1.5mm² 6701B LSZH cable (H07Z-K) rated 450/750V, supplied in white as a 100m length — a single-core, Class 5 flexible panel wiring cable ideal for environments where fire safety is critical.

This 1.5mm² H07Z-K LSZH cable is designed for wiring appliances, switchgear, instrument panels, and metering equipment. Its low smoke zero halogen (LSZH) cross-linked insulation dramatically reduces the release of toxic fumes and dense smoke in a fire, protecting both personnel and sensitive equipment. The flexible Class 5 stranded copper conductor makes installation in tight enclosures and control panels straightforward.

Key Features

• Low Smoke Zero Halogen Insulation (EI5): Minimises toxic fume and smoke emission during fire, safeguarding life and equipment in enclosed or public spaces.
• Class 5 Flexible Conductor: Plain annealed copper with 30/0.25mm stranding provides excellent flexibility for routing through panels and confined areas.
• 450/750V Voltage Rating: H07Z-K rated, suitable for a wide range of industrial and commercial low-voltage wiring applications.
• Wide Temperature Range (-15°C to +90°C): Performs reliably across demanding thermal environments without insulation degradation.
• Approx. 3.4mm Overall Diameter: Compact profile with 0.7mm radial insulation thickness, saving space in cable trays and trunking.
• BASEC Certified: Independent third-party certification provides assurance of quality and compliance.
• 100m Supply Length: Convenient reel length for project use, reducing waste and simplifying stock management.
• Approximate AWG Equivalent: 16 AWG: Useful reference for international specifications and cross-referencing.

Applications

This 6701B LSZH cable is suitable for internal wiring of appliances, switchgear panels, instrument panels, and metering equipment. It is particularly specified where smoke and toxic fumes arising in a fire situation may threaten life or equipment — such as hospitals, schools, transport infrastructure, data centres, and high-rise buildings. Its flexibility and compact diameter make it well suited to control panel construction and equipment wiring in industrial and commercial environments.

Frequently Asked Questions

What is the overall diameter and insulation thickness of 1.5mm² 6701B LSZH cable?

The approximate overall diameter is 3.4mm with a radial insulation thickness of 0.7mm.

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

Both are LSZH panel wiring cables, but the 6701B designation corresponds to the H07Z-K type rated at 450/750V, whereas the 2491B corresponds to H05Z-K rated at 300/500V — the key difference is the higher voltage rating of the 6701B.

What is the minimum bending radius for this cable?

The minimum bending radius is 3 times the overall diameter, which equates to approximately 10.2mm for this 1.5mm² cable.

Can this LSZH cable be used in public buildings and transport applications?

Yes — its low smoke zero halogen properties and compliance with fire performance standards BS EN/IEC 60332-1-2 and BS EN/IEC 61034-1 make it specifically suited to these environments.
