Specification

Belden 3074F 18 AWG 1 Pair Foil Shielded DataTray Twinaxial Cable

Applications:

The Belden audio cable is an electrical wire used in rough industrial environments for low-voltage audio signal control (i.e., voice communication, analog signals, line level audio, panel wiring). This audio wire prevents noise interference, provides better constant signal transmission, and is flexible for simple installation. The operating temperatures and voltage ratings of this electrical wire differ according to the product family.

Construction:

Conductors:

Belden wire may have different numbers of conductors that are drawn and annealed by the company and made of either solid or stranded copper.

Insulation:

Insulation is very important in any electrical cable since it prevents the electrocution of cable handlers. Belden cable’s insulation is made by the company, therefore offering a wide range of options, including Polyethylene, Polyvinyl Chloride (PVC), and Polypropylene insulation. Datalene and Teflon® Insulated Plenum insulation is also available.

Jacket:

The range of Belden wire jackets is quite wide and includes the following materials: Polyvinyl Chloride, Polyethylene, Polyurethane, Teflon®, Tefzel®, Neoprene, EPDM, Silicone rubber, and Natural rubber.

Shield:

Belden wire shields utilize techniques and innovations developed by the company and include the following variety: Foil shields (Beldfoil®, Duofoil®), Braid shields, Spiral/Serve shields, and Combination shields.

Armor:

Belden wire armor protects the cable and is made of aluminum or interlocking steel.
