PrometHighly Flexible E-Cu Ground and Power Straps

SHARE

Promet AG offers highly flexible grounding and power straps engineered from E-Cu flat braids, designed to effectively handle mechanical movements and bridge electrical contacts. These components are pivotal in diverse applications such as electrical engineering, plant construction, energy supply, and power transmission. The high adaptability of these connections is enabled by distinct braid structures combined with varied cross-sections and wire diameters between 0.05 mm and 0.20 mm. The EMK ground straps, a notable line of their products, utilize press-welding technology underwater to ensure top-tier quality and secure electrical connections. Available in both bare and tinned forms, these straps can be customized to meet specific needs, offering choices in dimensions, cross-sections, and even insulated varieties upon request. This versatility renders them suitable for low-resistance grounding and power transmission in various industrial and renewable energy sectors.

Highly Flexible Ground Straps Power Straps

Flexible. Powerful. Safe.

Our ground straps, power straps, and connections made of E-Cu flat braids are used wherever electrical contacts need to be flexibly bridged and mechanical movements compensated. They are ideally suited for use in electrical engineering, plant construction, energy supply, as well as grounding and power transmission applications.

The high flexibility of our power connections is determined by the structure of the braids, the cross-section, and the individual wire diameter (0.05 mm to 0.20 mm). We offer a variety of connection types, including:

  • Tin-dipped ends
  • Crimped copper or brass sleeves
  • Cable lugs
  • Custom special terminations

EMK Ground Straps – Patented Quality with Press-Welding

Our EMK type ground straps set standards: The connections are press-welded underwater in a special process – ensuring the highest quality and a permanently secure electrical contact. These straps are available in both bare and tinned versions.

As a manufacturer, we offer not only standard solutions but also customized ground straps and power straps, including special dimensions outside our listed products.

Your Advantages at a Glance:

  • No solder required
  • No contact sleeves needed (available upon request)
  • Minimal contact resistance = low heat generation
  • High current-carrying capacity
  • Low impedance for optimal performance
  • No mechanical weakening at the connection point
  • Homogeneous transition thanks to innovative manufacturing technology

Our power and ground straps made of E-Cu flat braids (individual wires Ø 0.15 mm, tinned as standard) impress with maximum conductivity and mechanical flexibility. They are universally applicable – as grounding strap, ground connection, or highly flexible power transmission element, especially where the lowest transition and connection resistances are required.

All cross-sections are also available by the meter as well as in aluminum version. Upon request, we supply insulated variants and special sizes – precisely tailored to your requirements.
