Intral’s aluminum clad steel wire ("Alumoweld") is used by the world’s leading manufacturers of overhead fibre-optic ground wire (OPGW). It is also widely used for preformed cable attachments.
Intral’s wire consists of a central steel core with a layer of high-conductivity aluminum extruded over it. The aluminum layer thickness is at least 10% of the wire radius and approximately 25% of the cross-sectional area. Conductivity being proportional to the aluminum layer thickness Intral manufactures a complete line of aluminum-clad steel wire with various conductivity levels. Conductivities ranging from 20% to 40 % I.A.C.S are available.
Single wire is sold onto wooden reels carrying weights up to 2 tons.
