In what scenario would MV (multi voltage) cable not be suitable for installation?

MV (multi voltage) cable is typically designed for specific installation environments and conditions. In the context of installation scenarios, there are certain areas where MV cable might not be the best fit.

When it comes to cable trays, they are generally intended for supporting and protecting electrical cables, especially those that may experience varying environmental conditions. Multi voltage cables, due to their construction and purpose, may not provide the necessary resistance to physical damage or environmental exposure that can occur in a cable tray setup.

Cable trays often have limited protection against external factors, such as moisture, dust, or physical impacts. Therefore, using MV cables in a cable tray without additional protective measures may lead to potential issues, such as insulation damage, short circuits, or even safety hazards.

In contrast, underground ducts, ceiling spaces, or exposed walls can often accommodate MV cables when appropriate measures are taken to shield them from moisture or other physical damage, making them more suitable environments for such installations. It is important to follow all local codes and standards when determining the most appropriate cable type and installation method for a specific context.
