318-B LSZH flexible cable is manufactured to harmonised standard H05Z1Z1-F and rated at 300/500V. It features fine stranded copper conductors with low smoke zero halogen (LSZH) insulation and sheath, providing improved fire performance compared to standard PVC flexible cable.

In this designation:

  • 318 identifies the flexible cable construction series

  • B denotes LSZH insulation and sheath

  • The core count appears in the middle (e.g. 3182B, 3183B, 3184B, 3185B)

LSZH flexible cable is commonly specified for public buildings, commercial premises, enclosed spaces and areas where smoke reduction and low corrosive gas emission are important safety considerations.

Available in multiple core counts, conductor sizes and drum lengths to meet trade and project requirements.

For standard indoor applications, view our PVC Flexible Cable – 318-Y (H05VV-F) range.

Next Day Delivery

Cut-Off Time and Order Information
To ensure your order qualifies for next day delivery, please place your order by 3:00 PM. This is subject to all items being available on the shelf at the time of your order. For orders where the total value exceeds £200 + VAT (double our standard carriage-paid order value of £100 + VAT), we are happy to split the delivery into two shipments if some items are needed urgently and others are not immediately available. If you have any questions or need further assistance, feel free to reach out to us via WhatsApp for live support. We’re here to help!

In Stock Delivery Policy

Free Next-Day Delivery Over £100 + VAT:
Orders above £100 + VAT qualify for free next-day delivery via DPD for in-stock items. While we strive for timely dispatch, we recommend placing orders early to avoid potential delays. Once dispatched, unexpected issues may arise despite the courier’s efforts.

Orders Below £200 + VAT:
To keep costs manageable, we dispatch your order once all items are ready, including products with longer lead times.

Need items faster? You can pay for an additional delivery service to receive in-stock items sooner. Simply email us with your order details, and we’ll send you a payment link for the extra delivery cost.

Orders Above £200 + VAT:
For larger orders, we can split delivery at no extra cost. In-stock items will be sent immediately, with the remaining items dispatched once available.

Supplier Lead Time & Availability

This item may be sourced from our supplier before dispatch.
The lead time shown is an estimate only and is based on the usual supplier timeframe. It is subject to supplier availability and is not a guaranteed delivery date.
We do not have a live supplier stock feed, so supplier stock can change without notice.
Delivery timers and courier estimates apply once the item is available for dispatch.
If the item is unavailable, we will contact you with the available options, including waiting for stock, choosing an alternative product, cancellation, or a refund for the unavailable item.
This does not affect your statutory rights.
