300/500V
Class 5 flexible stranded copper conductor, with Low Smoke Zero Halogen (LSZH) insulation and outer sheath
Commonly referred to as “318xB”
5, 6, 7 Core also available to A05Z1Z1 specification – DALI Lighting core colours
H05Z1Z1 cable is a low smoke zero halogen (LSZH) flexible cable designed for use in environments where fire safety, low smoke emission, and reduced toxicity are critical. At Qing Cables, we supply high-quality H05Z1Z1 cables suitable for internal wiring applications in commercial, residential, and public buildings.
These cables provide a safer alternative to standard PVC cables, making them ideal for installations where fire performance and safety compliance are essential.
H05Z1Z1 is a harmonised flexible LSZH cable designed for light-duty applications.
The designation means:
H – Harmonised cable
05 – Rated voltage 300/500V
Z1 – LSZH insulation
Z1 – LSZH outer sheath
Unlike traditional PVC cables, H05Z1Z1 cables emit low smoke and no halogen gases when exposed to fire, reducing risks to people and equipment.

When specifying cables for modern building installations, compliance, fire performance, and reliability are critical. At Qing Cables, we supply a comprehensive range of CPR Cca and CPR B2ca cables, engineered to meet the requirements of BS6701 and European CPR regulations.
The Construction Products Regulation (CPR) defines how cables perform in the event of fire, particularly in terms of flame spread, smoke production, and heat release.
BS6701 sets the standard for telecommunications and data cabling installations in the UK, requiring minimum CPR Cca ratings in many environments.
CPR Cca and B2ca cables: Higher fire performance cables with reduced flame propagation and lower smoke emission—ideal for high-risk or densely populated environments.
Both classifications are widely used in structured cabling, control systems, and building infrastructure to ensure safety and compliance.
Our range is designed specifically for:
– Office and commercial buildings
– Data centres and server rooms
– Smart building systems
– Industrial automation
– Airports and transport hubs
– Public infrastructure
By choosing CPR-rated cables, you ensure your installation meets legal compliance and insurance requirements, while improving overall fire safety performance.
