The document provides technical specifications for 33kV "V" cross arms, back clamps, and pole top brackets used in power distribution. It specifies that the
Cable tray is considered to be a system. It must provide continuous support for cables, and the electrical continuity of the cable tray system must be maintained.
The crossarm''s metal keepers maintain the proper bend radius for the slack cable. Cable straps (not provided) can be used to neatly group cable loops and secure them to keepers, if desired.
Vertical (V) Loadings ”Continuous” loading, normally the 60°F loadings, are those applied day in and day out for years at a time. This compares to the ”Intermittent” loadings or short term
When vertically stacking ladder trays always maintain adequate clearance above each tray run to allow for the installation of the cable and start with the narrowest (lightest) tray on top and work downwards
