MKH Enclosed Conductor System

Powerail MKH is a totally enclosed conductor system for indoor and outdoor use. The insulated housing can accommodate different copper sections such as: MKHD, MKHF, and MKHS.

A compact design, corrosion resistance and easy installation are the main characteristics. The MKH complies with VDE, European and International standards as well as accident prevention regulations. It is protected to IP 23 standards.

Powerail MKH Applications

  • Mobile power feeding of overhead cranes
  • Monorail systems
  • Electric hoists
  • Automated storage and retrieval systems
  • Assembly and test lines
  • Studio & station lighting systems and many others
