Every enclosure is only as reliable as its entry points. Wiska Cable Glands safeguard those entries with sealing and strain relief that survive weather, vibration, and maintenance. Whether you’re terminating flex, T&E, or SWA, Wiska glands uphold IP ratings and help you satisfy BS 7671.
Wiska Cable Glands At a Glance
- IP68 sealing options to resist dust and prolonged water exposure.
- Metric and PG thread sizes with clear cable‑O.D. windows.
- Plastic for general use; brass for SWA armour clamping and continuity.
- UV‑stable materials for long‑term outdoor reliability.
Plastic vs Brass: Choosing the Right Gland
Plastic glands are quick to fit, corrosion‑proof, and excellent for flex and T&E in outdoor lighting, CCTV, and signage. Brass glands are essential for SWA: they clamp the armour, deliver earth continuity, and resist impact and heat better in heavy‑duty settings.
BS 7671: The Regulations in Play
- Reg. 522.8.5 – Mechanical protection of conductors: glands provide clamping and strain relief so terminations aren’t stressed.
- Reg. 522.3.2 – Environmental influences: sealing stops water ingress and extends equipment life.
- Reg. 526.5 – Durability of connections: stable clamping maintains long‑term integrity.
- Reg. 134.1.1 – Good workmanship and materials: matched components are a compliance basic.
Installer Workflow That Stays Compliant
- Size matters: match cable O.D. to gland range; don’t oversize.
- Torque with feel: overtightening crushes insulation and degrades seals.
- Use brass for SWA, bond with tags, and verify continuity using appropriate earthing accessories.
- Inside the enclosure, keep tests quick with Wago 221 or Ideal push‑ins.
- For exposed runs, select outdoor‑rated cable and route to reduce UV and water pooling.
Case Study: Mixed‑Media Garden Install
A contractor ran SWA to a Combi 407 near the boundary, then flex to luminaires. Brass glands handled the SWA armour; plastic glands took the flex. Inside, Wago 221 made ring continuity and IR testing painless. After a year outdoors, the seals looked new and Zs values remained stable.
Common Mistakes (and Easy Fixes)
- Mixing thread types: keep M20 with M20 entries; avoid wobbly adaptors unless specified.
- Reusing glands: seals fatigue; new glands are cheap insurance.
- Cable ties instead of glands: fails compliance and invites ingress.
- No banjo on SWA: always maintain earth continuity on armour terminations.
