Trayer Switchgear ALTA Series Overhead Distribution Switch Engineered to Withstand Hurricane Conditions
Press release date: January 31, 2014
SAN FRANCISCO -- Trayer Engineering Corporation, a premier manufacturer of high-performance, distribution switchgear for electric utility and industrial applications, announces the ALTA Series of storm-hardened overhead vacuum switches for medium-voltage distribution systems. Designed for mounting on steel-reinforced, concrete poles, Alta Series switchgear are equipped to withstand Category 5 hurricane strength winds, heavy rain, dust and debris.
The ALTA System is made up of two pole-mounted units: a liquid-insulated, motor-operated vacuum switch and control cabinet designed to meet IP68 standards. The vacuum switch unit is equipped with field-replaceable porcelain bushings with provision for lightning arrestors and visual indication of switch position. The linear actuator can be decoupled from the switch handle to allow for manual operation. The heated control cabinet is designed to remain operational under storm flood conditions. The unit features pendant control access for field operation, battery backup and easy access to SEL relay control panel and SCADA hardware.
According to John Trayer, President and CEO of Trayer Engineering, "The ALTA Series was developed in response to the requirements of a coastal utility that suffered tremendous losses to its distribution equipment due to hurricanes. Our storm-hardened switchgear design and manufacturing techniques were essential elements in producing this remarkable product."
ALTA Series units are offered with 5kV, 15kV and 25kV ratings. All feature Trayer's signature welded 304 stainless steel, storm-hardened construction and SEL relay controls.
