Low Voltage Switchgear for Oversized Armoured Cables
We design and manufacture low-voltage switchgear that handles the challenges of large armoured cables. Standard enclosures often fall short when installers bring in oversized SWA cables. The minimum bending radius for these cables demands extra space inside the enclosure. Without it, teams face difficult choices on site.
Our team at A&T Enclosures works with contractors who need solutions that fit first time. We build floor-standing electrical enclosures in the UK that give cables the room they need. This approach keeps installations safe and compliant.
The Cable Radius Problem
Armoured cables like SWA types carry significant power in low-voltage systems. Manufacturers specify a minimum bending radius to protect the insulation and conductors. For larger cables, this radius can reach several times the cable diameter.
Standard enclosures leave little margin for these curves. Installers sometimes try to force the cable into tight spaces. We know this creates stress points that reduce the cable's working life. In low-voltage switchgear assemblies, proper cable routing also supports clear separation and maintenance access.
Common Installation Mistakes We Help Avoid
Teams often underestimate the space large cables require. They select an enclosure based solely on the switchgear components. Then the cables arrive, and the fit proves impossible without modification.
Some crews cut gland plates on site. Others bend cables sharper than recommended. Both actions risk voiding warranties and failing inspections. We have supported projects where such changes delayed handover by weeks.
Our process starts with full cable schedules. We review incoming and outgoing armoured cables early. This lets us position entries correctly and size the enclosure accordingly. Contractors tell us this early input saves time and reduces risk.
Gland Plate Considerations
Gland plates take heavy use in enclosures with large armoured cables. We design reinforced plates that support multiple large glands without distortion. Positioning matters too. We place plates to allow natural cable entry paths that respect bending radii.
In many cases, we supply removable gland plates for easier installation. Our fabricators create precise cut-outs that match the exact gland schedule. This level of preparation reduces on-site drilling and fitting time.
We also consider material thickness and sealing methods. Proper IP ratings remain intact even with multiple large entries. Our floor-standing electrical enclosures in the UK maintain structural strength around these openings.
How We Accommodate Oversized Cable Entries
At A&T Enclosures, we build bespoke solutions for these requirements. We increase enclosure depth or width where needed. Our team can extend the base or create dedicated cable compartments. This gives armoured cables the sweep they need without crowding the switchgear.
We integrate cable support systems inside the enclosure. These brackets and trays hold cables at the correct radius during and after installation. We also design entry points at optimal heights for floor-standing units.
Our manufacturing control lets us adjust dimensions, add internal frameworks, and fit custom gland arrangements as the design evolves. We work to BS EN 61439-2 and other relevant standards throughout.
Clients in power distribution, renewables, and industrial sectors choose us for this flexibility. We deliver low voltage switchgear that matches their cable specifications exactly. No unsafe modifications. No delays waiting for changes.
Our engineers bring over 30 years of combined experience to these projects. We understand how cable management affects overall system performance and safety. That knowledge shapes every enclosure we produce.
Benefits for UK Installations
Properly designed enclosures reduce installation time. Teams connect cables cleanly without rework. This leads to smoother commissioning and fewer inspection issues.
Maintenance also improves. Clear cable routes make fault finding and upgrades simpler. Our designs support the form separation and barriers that low voltage switchgear often requires.
We produce low-voltage switchgear that solves real installation challenges. Our approach keeps projects on track and systems reliable.
