I found it quite tight. 10mm 3core SWA has an o/d of 19mm approx, best advise is to order a pair of both 20mm and 25mm, at the price you can get them for on Amazon, then you decide which is is easier for you. Don't forget to fit everything onto the cable (shroud, nut, ring, etc) before fitting cables through gland body. **Q: what is the overall diameter please? thanks** A: The dia of the cable is 15.5mm **Q: can this be chewed through** A: I’m sure a rat could chew through it but ours is buried underground **Q: Is this cable suitable for driving on overground** A: No cable is designed for driving over. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great quality shielded cable. *by on Reviewed in the United Kingdom 4 October 2021* I bought 30 metres of this 3 Core 6 mm (SWA) Steel Wire Armoured Cable so I could have power in my shed at the bottom of my garden. I buried it in a thigh-deep trench and laid yellow warning tape above it, available from the same retailer. The cable came tightly coiled and was easy to uncoil and handle on my own. Judging by some of the comments / questions, people seem to be unsure of the external diameter of the cable, which is important when buying wall clips (see photo), and glands for connections at either end of the cable. Well I've just measured the external diameter of this 6mm cable with a digital calliper and it is 14.5mm.In conclusion, this is great quality cable and I'd buy it again. ### ⭐⭐⭐⭐⭐ Very sturdy. *by on Reviewed in the United Kingdom 1 April 2026* Very heavy duty cable , great for garages etc. ### ⭐⭐⭐⭐ Cable *by on Reviewed in the United Kingdom 28 December 2025* Good quality wire ## Frequently Bought Together - Ali's DIY 3 Core 2.5 mm (SWA) Steel Wire Armoured Cable - 1 Metre Custom Cut Length - BG Electrical Outdoor Double Switched Power Wall Plug Socket, Weatherproof, Nexus Storm, Grey, 13A, IP66 Rated, WP22 - SWA Pack of 2 CW20S PACK-ALT Gland Packs Suitable for Outdoor Use, SWA Armoured Cables, Brass Cable Glands --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/390370259-alis-diy-3-core-2-5-mm-swa-steel-wire](https://www.desertcart.pt/products/390370259-alis-diy-3-core-2-5-mm-swa-steel-wire) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-22*
