PMA LL-29S Гибкий провод

ABB Series LL Conduit, 32mm Nominal Diameter, Grey - LL-29S

This conduit provides flexible cable protection for industrial installations, designed for use in machinery, apparatus and general installation work. Manufactured from modified polypropylene, it offers a light-wall construction suited to pre-assembly and simple fitting in automated and electrical systems.

Features & Benefits

• Operates across temperatures from -20°C to 90°C for broad environments
  Resistant to strong acids to protect cable jackets in corrosive areas
  Minimum bend radius 55mm enables tight routing in confined spaces
  IP68 IP66 IP54 ratings allow deployment in wet and dusty conditions
  Compatible with M32 threaded fittings for secure terminations

**Applications**

• Suitable for cable routing within machine frames and control cabinets
  Ideal for installations requiring acid-resistant routing in plants
  Used with conduit glands and PMAFIX accessories in automation systems
  Can be used for fixed wiring runs in harsh factory environments

What material properties influence its insulating behaviour?

It is produced from specially modified polypropylene with a density around 0.90–0.92 g/cm3, giving very good electrical insulation and impact resistance.

How does it perform under repeated flexing?

The conduit withstands over 100,000 reverse bending cycles in standard tests, demonstrating long-term cyclic flexibility for moving or reconfigured assemblies.

Which approvals and test methods back its use in industrial settings?

It has been assessed against applicable EN/IEC and UL test criteria, with specific PMA test methods used for impact and pull-out performance.

What mechanical loads can connectors resist?

Pull-out resistance for conduit-to-connector assemblies exceeds 100 N under the referenced test procedure, supporting secure terminations during handling.
