Frequently Asked Questions
Q: What is the difference between indoor and outdoor medium voltage switchgear?
A: Outdoor medium voltage products are designed for installation in open air,meaning they must withstand solar radiation,wind,rain,snow,dirt deposits,condensation,and ice.Indoor products are designed for installation within buildings or other housing where they are protected from these environmental factors .Outdoor switchgear features weatherproof enclosures (NEMA 3R/IP54 or higher),corrosion-resistant finishes,heaters to prevent condensation,and wider temperature operating ranges .
Q: How is outdoor switchgear maintained?
A: Maintenance includes annual visual inspection of enclosure integrity,verifying door seals and gaskets,checking heaters for condensation control,and testing protection relays.Sealed gas-insulated units require no internal maintenance on primary components .Access to compartments is designed for safe,all-weather servicing .
Q: What's the typical lead time?
A: Standard pad-mounted and pole-mounted configurations typically ship within 6-10 weeks.Custom-engineered solutions or walk-in substations may require 12-16 weeks.
