Which installation parameters are important when installing cables into conduits or cable trays?

When installing cables into conduits or cable trays, clearance and jamming are crucial parameters to consider. Clearance ensures that there is enough space for the cables to be installed without causing damage or excessive pressure on the cables. This is essential because cables must not be tightly packed together, which could lead to overheating or mechanical damage.

Jamming refers to the risk of cables becoming stuck or trapped during the installation process, particularly if the conduit or tray is too small or if the layout is not properly planned. If cables are jammed, it can complicate future maintenance or replacement and may lead to increased wear and tear over time.

In sum, considering both clearance to avoid crowding and jamming helps ensure a safe, efficient, and reliable installation process that minimizes risks associated with cable handling and operation in the system. Other parameters like environmental factors also play a role but are not as directly related to the physical aspects of installation as clearance and jamming.
