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

The LSZH-1.5-GREY-1 is a 1.5mm² 6701B LSZH single core cable (H07Z-K) in grey, supplied on a 100m reel. This Class 5 flexible panel wiring cable is rated 450–750V and designed for use in environments where low smoke and zero halogen properties are critical to safety. It is ideal for switchgear, instrument panels, metering equipment, and appliance wiring where toxic fume reduction during a fire is essential.

Key Features

• LSZH Insulation (Type EI5): Cross-linked low smoke zero halogen insulation minimises toxic fume and smoke emission in fire situations, protecting personnel and sensitive equipment.
• Class 5 Flexible Conductor: Plain annealed copper with 30/0.25mm stranding provides excellent flexibility, making installation in tight panel enclosures easier.
• 450/750V Voltage Rating: H07Z-K rated for robust performance in higher-voltage panel wiring and equipment applications.
• Wide Temperature Range: Suitable for operating temperatures from –15°C to +90°C, allowing use across diverse industrial environments.
• Compact 3.4mm Diameter: Approximately 3.4mm overall diameter with 0.7mm radial insulation thickness, keeping cable routing manageable in dense wiring configurations.
• BASEC Certified: Independently certified for quality and compliance, giving confidence in cable performance and traceability.
• 100m Supply Length: Supplied on a 100m reel at approximately 2.1kg, convenient for panel building and project-based requirements.

Applications

This 1.5mm² 6701B LSZH cable is specifically suited for internal wiring of appliances, switchgear, instrument panels, and metering equipment. It is widely used in control panel building, industrial automation enclosures, and any installation where smoke and toxic fumes arising in a fire could threaten life or damage sensitive equipment — including public buildings, transport infrastructure, and data centres. The approximate AWG equivalent is 16 AWG, with a bending radius of 3 × overall diameter (approximately 10.2mm).
