Fibre ratio eases enclosure customization

To protect installed components, the ARCA IEC cabinets can be easily and inexpensively machined, says Fibox.

Up to IK10 impact resistance is ensured by the enclosure design with reinforced corners and doors, combined with the special glass-fibre-reinforced polycarbonate (FRP) material. By reducing the fibre ratio to 10 per cent, the company claims it has eliminated the disadvantages occurring with other materials.

The polycarbonate enclosures can be customised with conventional tools, and with negligible wear, says the company. Chips and debris material do not need to be suctioned off while working. In other enclosure materials, threaded holes can lose their function under strain, but these enclosures enable long-time, durable threads up to M25 and M32, providing a permanently strong hold for cable gland fittings. They do not suffer from blooming, i.e. the effect of decreasing surface quality in FRP polyester cabinets after a few years in the open air, which is also associated with the release of glass dust. According to the company, the polycarbonate enclosures have a long-lasting, smooth surface with excellent UV resistance.
