Tips For Protecting Your Substation
Substations play a critical role in ensuring a stable and controlled electricity supply in homes, businesses, and industries. They (step down) transform high-voltage electricity to low-voltage, making it safe for use. Due to the critical nature of their functions, substations need to have regular maintenance to ensure a sufficient and safe power supply. One of the most important maintenance services you should conduct on your substation is painting and repainting surfaces.
Why should you paint your substation?
Substations surfaces such as transformers are made of galvanized steel, which rusts over time. Rust poses severe fire and electrical risks, hence the need for painting. Paint covers the substation surfaces, therefore protecting them from moisture that could lead to rust. Substation painting involves using protective coatings that control corrosion, ensuring longevity and effectiveness.
How can you protect your substation after painting?
The following are some of the techniques you can use to protect the paint on a substation:
1. Temperature regulation
One of the factors that lead to erosion of paint in substations is thermo-cycling. That is when machinery and equipment are exposed to high temperatures over a short time. When this happens to substation surfaces, galvanized steel expands then contracts when cooling, affecting the paint. To protect the color, you need to regulate the temperature levels in the substation. You should install insulator coatings that can handle high voltage and temperature.
2. Cleaning off dust
Another way of ensuring the paint in your substations lasts longer is through dusting. Dust particles lead to abrasion when they contact steel surfaces. It is hard to recognize the abrasion since it happens over time. When the dust accumulates, the abrasion continues, and the paint on the steel surfaces starts to fade. Regular cleaning of the substation removes dust from the steel, reducing the abrasion rate and ensuring the paint's durability in the long run.
3. Use UV Absorbers
Ultra-violet (UV) lights from the sun are one of the factors that severely destroy paint. Exposure of the steel to excess UV lights damages paint and results in rust to the steel. Unfortunately, you cannot regulate the amount of light the sun produces. But, the painting company can use UV absorbers for coatings during painting, which helps minimize sunlight effects. The absorbers do not block UV rays but release radiation to protect the paint.
Protecting the paint in your substation is essential for promoting smooth electrical operations, preventing rust, and enhancing its visual appeal. However, you have to ensure you get the correct paint.
