Product Information

Specification

777 MCM Polyrad XT Flexible Rapid Transit Wire 600V

Application:

• Ideally suited for use where environmental factors require cable characteristics to perform with a high degree of flame retardancy and excellent moisturestable electrical values. Where reliability is the major concern and where maximum performance will be demanded
• Engineered and manufactured for both original equipment and retrofit use in power and control circuits and in motor leads
• Extensively found on all types of heavy- and light-rail cars, rapid transit cars, diesel-electric locomotives, freight cars, wayside equipment and off-road vehicles
