Included with the RBK is engineering support in. Working with Southern California Edison, INWESCO has helped redesign a platform to better withstand wind and seismic loads. The system is shipped as a kit that incorporates retrofit-style anchor brackets and rod stiffener clamps.

Transformer platforms can be designed to better withstand wind loads and seismic loads and better protect your investment in transformers. This manual is required to be on the job site. It can be bolted or welded to the equipment, and is. What is High Quality Cable Tray Bi-Directional Seismic Brackets Longitudinal Seismic Brackets Seismic Brackets for Electrical Bridges, Anti-seismic. The photo has been rotated from vertical to horizontal for easier viewing. Model KSMS seismic and wind restraint brackets are used to solid-mount equipment to the building structure.

Lineman taking pictures from a bucket reported the normal ½ inch gap between the bottom bolt and the top of the slot in the frame had closed, and the bottom of the bracket had gouged into the pole approximately 3/8 to ½ inch.Įxisting Heavy Transformer Bracket Design - Splitting of the pole was observed, potentially related to overstressing of the bolts.Įxisting Heavy Transformer Bracket Design - Perspective of areas of stress described in previous slides. Lineman taking pictures from a bucket reported gaps between the top of the heavy framing member and the pole of approximately ½ inch. Break-off bolt heads provide visual verification of proper torque and installation to the structure and attachment to the seismic brace component. Below are four pictures to illustrate a problem with excessive stress on utility poles caused by design inadequacies in existing transformer cluster brackets. Let's look at field data from Southern California Edison.Ī lineman identified a problem pertaining to the common transformer cluster bracket.
