Armored low voltage cables are characterized by a reinforced mechanical protection, a better resistance to external constraints and one increased structural stability, enabling reliable installation in more demanding operating conditions.
ZMS expert council
Armored low voltage cables are recommended for buried installations, THE exposed industrial environments or poses presenting a high mechanical risk.
When mechanical constraints are limited and the installation is protected, the use of unarmored low voltage cables allows for simpler implementation ; in case of specific thermal or fire safety requirements, low voltage cables Xlpe you lszh may be preferred depending on the project conditions.
Flexible Low Voltage Cable
The flexible low voltage cable is made of copper or aluminum conductors, generally with multi-strand structure, associated with insulation and a sheath designed to support mechanical deformations.
This design gives the low voltage flexible cable a great flexibility, a increased resistance to repeated bending and reliable aptitude for dynamic configurations. It facilitates installation in complex paths while ensuring stable electrical continuity, even in the presence of frequent movements or moderate mechanical stress.
ZMS expert council
When the installation involves regular movements, frequent maintenance operations or reduced curvature radius constraints, the flexible low voltage cable is a more relevant choice than a rigid cable.
For systems where long-term reliability depends on the cable's ability to absorb mechanical stress without premature degradation, the use of a flexible low-voltage cable optimizes the durability and safety of the installation.
Rigid Low Voltage Cable
The rigid low voltage cable is made of copper or aluminum conductors, with massive or weakly stranded structure, associated with insulation and, if applicable, an outer sheath intended to ensure lasting mechanical stability.
