Which Common Armoured Cable Gland Buying and Installation Pitfalls Should Electrical Buyers Skip?

2026-08-07

Numerous electrical contractors encounter preventable gland‑related failures caused by overlooked BW‑2 Armoured Cable Gland purchasing and assembly traps.

Avoidable mistakes trigger water ingress, broken earthing continuity and costly on‑site cable‑rework labour expenses.

We break down the most‑frequent pitfalls and share actionable fixes for every BW‑2 armoured cable‑gland end‑user.

Every warning point draws from years‑long wholesale‑client feedback and field‑failure case records.

Pitfall 1: Buying Glands Without Confirming Cable Outer Diameter Range
Many bulk purchasers select BW‑2 Armoured Cable Gland units only checking thread specifications.
A mismatched clamping‑diameter range will never properly fasten your thick or slim armoured power cables.
Solution
Measure both cable outer sheath diameter and exposed‑armour dimension before you finalise your gland‑order list.

Pitfall 2: Purchasing Cheap Un‑Plated Brass Generic Replacements
Low‑cost raw‑brass Armoured Cable Glands quickly build up surface rust in damp, coastal and chemical‑exposed locations.
Corroded thread surfaces jam the BW‑2 Armoured Cable Gland and ruin armour‑earthing conductivity.
Solution
Always select nickel‑plated finished BW‑2 Armoured Cable Gland units for non‑dry indoor‑only projects.
Pitfall 3: Over‑Tightening the Compression Cone
Excessive spanner torque crushes steel‑wire armour strands and scratches the cable’s inner insulation layer.
Damaged insulation raises the risk of short‑circuit and earth‑leakage faults.
Solution
Tighten until armour strands stay fixed; stop applying force once the cable cannot slide manually.
Pitfall 4: Losing the Rubber Sealing Washer During Assembly
Workers frequently misplace the thin sealing gasket when assembling the BW‑2 armoured cable gland.
Missing washers completely destroy the IP68 dust‑proof and waterproof sealing capability.

FAQ
Q1: Why does my armoured cable gland keep getting loose under vibration?
A1: You might have skipped tightening the hexagonal lock nut or selected a BW‑2 armoured cable gland with poorly‑finished rough threads.
Our precision‑threaded nickel‑plated bodies deliver superior anti‑loosening performance.
Q2: Can I reuse a previously‑installed BW‑2 armoured cable gland?
A2: Re‑use is acceptable only when thread surfaces and sealing components remain scratch‑free and undamaged.
Replace worn rubber gaskets every single time you re‑assemble the cable gland.
Q3: What causes water leakage around my armoured cable gland?
A3: Common triggers are missing sealing washers, improperly stripped cable jackets, and insufficient compression from your BW‑2 armoured cable gland cone.
