About this file
This document is a technical specification section (33 72 23.13) for Bus Support Insulators, likely for Knoxville Utilities Board (KUB) in Tennessee. The specification details requirements for station post and pedestal post insulators with various voltage ratings including 15kV, 69kV, and 161kV. The document provides comprehensive catalog numbers from multiple suppliers like Victor, Lapp, Newell, Locke, PPC, Hubbell, and TE Connectivity for specific insulator types and configurations.
The specification outlines technical requirements including Basic Impulse Level (BIL) Impulse Withstand ratings ranging from 110kV to 750kV and specifies that the insulator glaze shall be light gray (ANSI Z55.1, Color No. 70). The document appears to be part of a broader procurement process for electrical infrastructure components, with a revision date of 03/29/24 and a planned future revision on 12/18/2024 to update catalog numbers and add pedestal post details. The specification is intended to provide precise technical guidance for procuring standardized bus support insulators that meet specific electrical infrastructure requirements.
