Preventing Oxidation in Electrical Accessory Manufacturing: Humidity Standards & DeAir Solutions

The "Invisible Enemy" of the Electrical Accessory Industry

For manufacturers of electrical accessories (sockets, switches, cables, circuit breakers...), the two most critical materials are Copper (Cu) and Silver (Ag). However, these are also metals extremely sensitive to humidity. Once environmental humidity exceeds 60%, the oxidation process accelerates exponentially, turning shiny copper bars into tarnished, rusted metal overnight.

So how can you protect raw materials and finished products to meet export standards? This article analyzes international standards and specialized humidity control solutions from DeAir.

1. Why Control Humidity in Electrical Factories?

The presence of water vapor in the air is a powerful catalyst for oxidation reactions. The consequences of uncontrolled humidity in electrical equipment manufacturing plants are severe:

• Increased Contact Resistance: Oxidized copper/silver contacts create an insulating oxide film, causing equipment to overheat during operation, potentially leading to short circuits or fire.
• Surface Tracking Failure: Moisture on insulating plastic surfaces (Bakelite, PC) reduces insulation resistance, causing high-voltage leakage.
• Packaging Damage: Cardboard boxes containing finished products become soft and moldy, losing the aesthetic value of the product.

2. Recommended Humidity Standards (ISO & IPC)

To prevent metal corrosion, factories need to adhere to safe humidity thresholds based on reputable international standards:

DeAir recommends the following humidity levels for specific areas in electrical accessory factories:

• 🏢 Raw Material Warehouse (Copper, Steel, Plastic Granules): 45% - 50% RH.
• 🏭 Stamping/Molding/Assembly Area: 50% - 55% RH.
• 📦 Finished Goods Warehouse (Carton Packaging): 50% - 60% RH.

4. DeAir Solution: Comprehensive Protection from Warehouse to Workshop

DeAir provides industrial dehumidifiers with Heat-Pump technology, helping to save 40-60% of electricity compared to older technologies, optimizing operating costs for electrical equipment factories.

Application 1: Humidity Treatment for Material & Finished Goods Warehouses (DeAir.RE-Series)

The large capacity DeAir.RE Series (from 100L to 1200L/day) is the most economical choice for controlling humidity in the range of 45% - 60%.
