Uninsulated aluminium wires

Uninsulated aluminium wires are used for electrical supply lines (networks). They are fastened on insulators during their exploitation.

JSC “JAUDA” produces aluminum wires using German equipment whom appropriate technical service is provided.

The enterprise produces two types of uninsulated aluminium wire – "A" and "AC". "A" type wire is made from 7 separate aluminium wires of definite diameter and number. "AC" type core is made from special iron wires or definite number of wire coils around which 6 aluminium wires are spooled.
