Equipment for the production of wires and cords PVA SHVVP

Production of PVA wires and cords SHVVP in Russia is made in accordance with GOST 7399-97. PUGNP wires in RF discredited themselves completely - it's like a red rag to the supervisory authorities - manufacturer produces non-compliant products. To release them, you can, but it is worth thinking about another title or writing specifications on this product in strict accordance suppose with GOST 31947-2012.

The main materials for the manufacture of these products are copper rod and PVC compound. Set the process equipment will be different for different PPC issue volume.

Below we consider two options.

1. A full cycle of production of wires and cords PVA SHVVP

The complete cycle includes the following operations:

  • rough drawing of copper;
  • mean drawing copper (ONE WAY or multi-way);
  • twist TPG (conductor);
  • isolation TPG;
  • twist isolated TPG;
  • of the outer coating sheath;
  • 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 chosen technology and manufacturing capacity.

If extrusion and twisting TPG and TPG isolated all more or less clear, the rude and mean drawing allows multiple options - combined with the process of drawing a joke - a joke a single wire (in muffle furnaces or furnaces with a hydraulic lock).

2.

truncated cycle of production of wires and cords PVA SHVVP
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;
  • average copper wire drawing - you can buy on the market ready-made copper wire;
  • twist TPG (conductor) - you can buy on the market ready-curled TPG;
  • isolation TPG;
  • twist isolated TPG;
  • the application of the outer shell, combined with the unwinding (buhtovkoy)
  • packaging of finished products;
  • acceptance tests;
  • Accessories (coils, reels, welding devices, extrusion tools, drawing tools - dies)
  • .

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 of wire or cord PVA SHVVP

The range will look like this:

  1. The machine is a rough drawing with integrated annealing to pass;
  2. Vosmihodovaya line drawing medium with integrated annealing to pass;
  3. Two cars double twist to a receiver 630 and a set of pay-off reel under 630;
  4. The machine double twist with a receiver 1000 and a set of pay-off reel under 630;
  5. 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);
  6. oshlangovaniya line based on the extruder with a screw diameter of 100 mm (and can be 90);
  7. The line of automatic unwinding and packaging;
  8. Cable drums of different diameters, accessories, test equipment, extrusion tools, drawing tools, engineering systems.
