Technical description

obudowy

In response to customers’ needs in the area of delivery of high quality cable cubicles made of thermoset fibre glass reinforced polyester SMC, the ZPUE S.A. company manufactures the best quality SKRD and SKRF type thermosetting cubicles thanks to a modern machine park and excellent human capital. Taking careful note of the customers’ opinion of already existing technical solutions and suggestions for their potential modifications, we have manufactured a range of cable-distribution cubicles “SKR”, adapted to the national power distribution companies’ requirements. Our company, as a leading manufacturer, constantly develops production technology, which results in the highest quality products. All products offered have the necessary certificates.

Production technology

A very important element, which guarantees the highest construction quality and the long life of the cubicle is its material. ZPUE S.A. uses its long-standing contacts with industrial chemical manufacturers in Europe, and the knowledge and experience of people who deal with SMC material treatment technology. The materials used in the cubicle production process consist of a range of components fulfilling the requirements of mechanical, thermal and UV resistance, which guarantees the long life of our cubicles.

Field of application

Thermosetting cubicles, thanks to their universality, can be widely used in the energy and telecommunication industry. They are made of isolating and self-extinguishing material and flame retardant composite: (polyester +fibre glass – SMC) and they are characterized by high weather conditions resistance (UV). Its modular construction allows any combination of the cubicle with the foundation, extension or cable pocket, and for connecting cubicles in a horizontal or vertical arrangement. Various dimensions allow selecting the cubicle according to the customer’s needs or equipment used. The specially developed internal construction of the cubicle with additional elements integration allows quick and convenient equipment and apparatus installation inside the cubicle. The cubicles are powder-painted in the standard colour: RAL 7035. Upon customer’s request, they can be covered with a special coating of plastic in any colour from the RAL palette.

Characteristics and advantages of “SKR” cubicles

Made of the highest quality, self-extinguishing SMC material. Excellent durability and high aesthetic finish for many years to come. UV and changing weather conditions resistance. Very high mechanical strength. Ventilation sufficient to drain excess humidity. Modular construction allows replacement of faulty elements and vertical or horizontal cubicle separation. Possibility to configure any box or to develop the existing one. Possibility to equip with slat switch disconnectors (320 mm type allows parking ). Three-point door lock made of plastic or metal. Possibility of quick and easy door and cover removal from the foundation without using tools makes maintenance easy for technicians. The external surface of the cubicle is ribbed which improves the aesthetics and prevents posting.
