A rubber pad is installed in the mounting position to prevent cable tray burrs from scraping cable
sheathings.
The cables are long. Assign sufficient people and ladders to carry the cables onto the cable
tray.
Before mounting cables on the cable tray, understand the installation precautions and the
regulations for working at heights, and put on necessary protective equipment such as
safety helmets and gloves.
After mounting cables on the cable tray, lay out the cables horizontally without twists and
bind the cables in proper positions with cable ties.
Reserve sufficient cable length and bending space when turning an armored power cable.
If possible, place armored cables and thick cables on the outside and lower layer of the
cable tray.
The cable bend radius must meet requirements.
Fire control cables and monitoring cables must be placed in the inside on the upper layer
of cable trays.
Armored cables and power cables must be placed in the outside and bottom layer of cable
trays.
Cables must be level, without unevenness and deflection.
