AC90 cable is one of the most trusted armored cable types. It's known for its strength, flexibility, and ability to protect conductors without the need for additional conduit.
if not installed or maintained properly. Dents, kinks, abrasion, and crushing forces can all shorten its lifespan and compromise safety.
So-how do you prevent mechanical damage to AC90 cable and ensure long-term reliability? Let's explore.
Understanding AC90 Cable
AC90 cable (Armored Cable 90℃) that provides mechanical protection and flexibility. Inside, insulated copper or aluminum conductors are wrapped with moisture-resistant barriers to ensure stability under various operating conditions.
- 90℃ rated thermoplastic insulation for heat resistance
Compared with other types, AC90 stands out for its balance of durability, cost-efficiency, and ease of installation.

Common types and causes of mechanical damage to AC90 cables
Even with its armored design, AC90 cable can still face challenges in harsh conditions. Typical forms of
- Dropped tools, heavy equipment, or foot traffic on unprotected runs.
- Over-tight cable pulls or small bend radii during installation.
- Cable rubbing against sharp metal edges or vibrating surfaces.
- Heat, corrosion, or vibration in industrial environments.
- Coils dropped, twisted, or bent before installation.
Understanding these causes is the first step toward prevention.
Key measures to prevent mechanical damage to AC90 cable
CSA/UL-approved AC90 cable with suitable conductor size and armor thickness for the environment.
ACWU90 instead.
- recommended by the manufacturer.
- Avoid excessive pulling tension-use pulling grips or wire baskets.
- Support the cable at appropriate intervals per NEC/CSA standards.
- Protect exposed cable sections using metal trays or PVC sleeves in high-risk zones.
- in areas prone to physical impact.
- Clearly mark high-voltage or critical power circuits with warning labels.
- to detect early signs of armor wear or loosening.
Use High-Quality Connectors and Fittings
- CSA-approved strain relief connectors to prevent cable pullout.
- Ensure continuous grounding through armored connections.
- For vibration-heavy installations, use anti-loosening locknuts or clamps.
Typical Applications and Best Practices to AC90 cable
In a manufacturing facility, AC90 cables were used to power production equipment. By installing the cable within protective steel trays and securing every 1.2 meters, the maintenance team reduced cable failure incidents by over 80% within a year.
