- In the Russian Federation, most of the outdoor electrical wiring boards are made in metal cases.
- The main disadvantage of such cases is corrosion, and therefore they need to be coated annually with a protective paint layer.
- Frequent adverse weather conditions in Russia only exacerbate the situation and dramatically reduce service life.
- Depending on climatic conditions, this period is, on average, 5 years.
- The degree of dust protection of metal IP enclosures initially declared by the manufacturer often decreases with time due to drying and chipping of the rubber bands of the seals.
- These factors adversely affect the state of equipment installed in such housings, which are often expensive, and contribute to its speedy failure.
- Less than half a century ago, housings made of composite SMC materials were developed in Europe.
This development has a number of advantages compared with its metal counterparts from steel and aluminum.
