The brennenstuhl® BREMAXX®-PUR (BQ cable) is designed for demanding conditions. The cable jacket is made of polyurethane (PUR), making the cable especially robust and durable. This makes the BQ cable particularly suitable for continuous outdoor use as well as for construction sites and commercial applications.
What are the advantages of a polyurethane cable jacket?
Polyurethane combines high mechanical durability with good resistance to various environmental influences. The BREMAXX®-PUR BQ cable offers the following features, among others:
- extremely mechanically durable and abrasion-resistant
- weather-resistant
- acid-resistant
- microbe-resistant
- cold-resistant down to −40 °C
- suitable for construction sites and demanding commercial applications
This makes the BQ cable especially advantageous where a cable is frequently moved, routed over rough surfaces, or exposed to weather and other environmental influences.
Why is a BQ cable less flexible?
The high robustness of the PUR cable jacket also affects handling: Compared to particularly flexible rubber/neoprene cables, a BQ cable can feel stiffer or less flexible.
This is not a defect in quality but a practical consequence of the cable jacket designed for high durability and abrasion resistance. For example, brennenstuhl explicitly describes RN cables with rubber-neoprene jackets as flexible, whereas the BREMAXX®-PUR BQ cable emphasizes extreme mechanical durability and abrasion resistance.
In short: When robustness, weather resistance, and durability are especially important, the brennenstuhl® BREMAXX®-PUR (BQ cable) offers clear advantages. However, if maximum flexibility is primarily needed, the type of cable and intended area of use should also be considered when making a selection.
