Equipment for the production of cables of VVGng (A) -LS and VVGng (A) -FRLS

Production of cables of VVGng (A) -LS and VVGng (A) -FRLS in Russia is made in accordance with GOST 31996-2012. Currently, almost all of GOST standards in the Russian Federation have the kind of "General specifications". For the production of cables and wires on the basis of the requirements of GOST manufacturers develop their own technical specifications.

The main materials for the manufacture of these products are copper rods, PVC-PLASTIC low flammability, low smoke and gas emission and mica tape. Set the process equipment will be different for different PPC issue volume.

Below we consider two options.

1. Full production cycle VVGng cable (A) -LS and VVGng (A) -FRLS

The complete cycle includes the following operations:

  • rough drawing of copper;
  • winding TPG mica tape for cables with index «FR»;
  • isolation TPG;
  • twist isolated TPG;
  • overcladding while filling;
  • unwinding and packing of finished products;
  • acceptance tests;
  • Accessories (coils, reels, welding devices, extrusion tools, drawing tools - dies)
  • .

Accordingly, at each process step requires a separate piece of equipment. Number of process equipment will depend on the production volume.

To meet the requirements of GOST, smoke and presence of the inner lining of gassing necessarily, respectively operation "overcladding" should be combined with the operation of "filling" and performed on a tandem extruder.

2. Truncated cable production cycle VVGng (A) -LS and VVGng (A) -FRLS

Truncated cycle implies a refusal to comply with a number of technological operations.

  • rough drawing of copper - you can buy on the market ready-made copper wire;
  • winding TPG mica tape for cables with index «FR»;
  • isolation TPG;
  • twist isolated TPG;
  • the application of the outer shell while filling, combined with the unwinding (buhtovkoy)
  • packaging of finished products;
  • acceptance tests;
  • Accessories (coils, reels, welding devices, extrusion tools).

Pros and Cons of truncated cycles are clear: savings on investment in equipment and production areas, energy savings (receiving power allocation), savings on maintenance staff, but also obvious loss of added value is not manufactured operations, complete dependence on suppliers of components and as a set of data ( especially strongly can affect in high season - April - November), damage components during transportation and handling operations.

A typical set of equipment for the production VVGng(A)-LS and VVGng(A)-FRLS

The range will look like this:

  1. The machine is a rough drawing with integrated annealing to pass;
  2. taping machines;
  3. The machine double twist with a receiver 1000 and a set of pay-off reel under 630;.
  4. The line isolation on the basis of the two extruders 80 (versions 70 and 90) 45 (one for surface color and two-color manufacturing wire - yellow-green);
  5. The tandem line oshlangovaniya based extruders with a screw diameter of 100 mm (can be 90);
  6. The line of automatic unwinding and packaging;
  7. Cable drums of different diameters, accessories, test equipment, extrusion tools, drawing tools, engineering systems.
