Bare Rope-Lay Bunch Stranded Conductors

1X Technologies manufactures custom bare copper rope-lay-stranded conductors having bunch-stranded members from round copper wires, either un-coated or coated with tin, lead, or lead-alloy for use in electrical conductors.

Rope-lay-stranded conductors having bunch-stranded members are classified as Class I, Class K, and Class M. Necessary joints in wires or in groups of wires shall be made in accordance with accepted commercial practice, taking into account the size of the wire or group of wires as related to the size of the entire conductor. Conductors of the same size and description furnished on one order shall have the same lay.

Extra Flexible Rope-Lay Bunch Strand

In very flexible conductors, such as welding conductor, the direction of lay of the stranded members forming rope-lay-stranded conductor may be in the same, rather than in reversed. For the purpose of calculating the mass, cross sections, etc., the density of copper shall be taken. The mass and electrical resistance of a unit length of stranded conductor as a function of the length of lay shall be measured.     

Extra Large sizes on Rope Lay Bunch Strand Conductors –  Water Cooled Cables for Steel Melting

We manufacture Bare Rope-Lay Bunch Stranded Conductors  in extra large sizes used for many applications, often for ARC furnaces and as the conductors for water cooled cables. Although they have found use in other industries, the large water cooled cable is primarily used in electric steel melting using the Electric Arc Furnace (EAF) and Ladle Furnace processes. When combined within a water cooled cable this can be as large as 20,000 MCM or KCMIL.
