Control Cables | Connection Cables

Control cables & connection cables are used for power supply for all electric motors. In general, control cables have a green/yellow earth conductor in the outer layer of the twisted unit.

To avoid the spread of existing electromagnetic fields, we often manufacture control cables with tinned copper braiding. Furthermore, we manufacture cables with PUR outer sheaths that are suitable for an application in harsh environmental conditions such as in glass manufacturing or in metal chipping industries.

    Questions & Answers

    • What are PUR cables and what are their advantages?

      Polyurethane (PUR) – Thermoplastic Elastomer (TPE)
      PUR stands for ‘polyurethane’. The insulation and sheathing material “PUR” is a thermoplastic elastomer (TPE) and has become increasingly important in the cable industry due to its special properties and advantages.

      This material exhibits mechanical properties similar to rubber at certain temperatures. The combination of thermoplastic and elastic properties has led to the description TPE thermoplastic elastomer. Here at SAB Bröckskes GmbH & Co KG we use PUR on a polyether base as a sheathing material. In addition to standard polyurethane, thanks to continuous development between SAB Bröckskes and the plastics industry, the following types of PUR are also available:

      PUR types from SAB Bröckskes:

      – PUR semi-mat (low adhesion)
      – PUR mat (raw surface, low adhesion)
      – PUR flame retardant
      – PUR halogen-free and flame retardant

      Mechanical properties of PUR cables
      The insulation material of the cables is usually not subject to high mechanical stresses. Slides, on the other hand, are widely used. This is especially true for flexible control and connection cables that are often routed over sharp corners and rough surfaces. This can lead to cuts that are accentuated when the cable is stretched during flexible use. Compressive stresses caused by crushing and impacts from tools and machinery may also occur.
