MKL Enclosed Conductor System

Vahle Inc. offers our MKL Conductor Line as replacement/spare parts only, not new systems.
Our MKL line has been replaced by our MKH line.

MKL Enclosed Conductor SystemMKL is a totally enclosed conductor system with 6 - 10 conductors, for indoor and outdoor use. The gray coloured housing can be supplied with different copper sections for ratings from 40 - 200 Amp. After installation of the PVC housing the flat copper bars, supplied in coils, are to be pulled into the housing, using factory-supplied tools. MKL requires a minimum of space, is easy to install and cannot corrode. Typical applications are overhead cranes, monorails, hoists, storage and retrieval systems, power tools, lighting systems and many others.
