Corrosion-Free Peace of Mind for Switchgear, JB, and MTB Export
April 12, 2024
The question of how to get switchgear, junction boxes (JBs), or main terminal boxes (MTBs) from point A to point B requires more than just hiring space on a truck or container ship. When shipping to international customers, manufacturers must find ways to protect sensitive electricals from hot, humid, salt-spray conditions that could cause corrosion during export or storage. Cortec® shares three simple ways to keep equipment corrosion-free until commissioning.
Step One: Protect Metal Contacts#
Workers can spray terminals, copper breakers, and other uncoated metals with ElectriCorr™ VpCI®-239. This can be used as a cleaner/degreaser to remove dust or grime from manufacturing, and it can be left to dry as a very thin film that inhibits corrosion in aggressive conditions.
Step Two: Add VpCI® Emitters#
VpCI® Emitters are perfect for protecting multi-metal types inside an enclosed space. These devices come in a variety of forms and release Vapor phase Corrosion Inhibitors that adsorb on metal surfaces, creating a molecular protective layer. They can be dosed based on enclosure volume:• VpCI®-101 Device – Protects 1 ft³ (28 L)
• VpCI®-105 Emitter – Protects 5 ft³ (0.14 m³)
• VpCI®-111 Emitter – Protects 11 ft³ (0.31 m³)
• VpCI®-308 Pouch – Protects 35.3 ft³ (1 m³)
Step Three: Shrink Wrap#
The outside of switchgear cabinets and JBs or MTBs can and should also be protected by wrapping the entire cabinet in VpCI®-126 HP UV Shrink Film. This not only provides a physical barrier but also contains corrosion inhibitors that work in both the contact and vapor phase, actively protecting the metal exteriors of the boxes from corrosion.
Get Ready for Export#
Export is an important phase in the industrial supply chain. By following the steps above, manufacturers can ship electrical enclosures through a variety of unpredictable conditions, get them to customers in like-new condition, and keep them that way until installation time.
