Electrical Insulating Cardboard: For Patterns, For Furniture And Other Production

Electrical insulating cardboard: for patterns, for furniture and other production.

The working names of this material are " electrocarton ", " pressstamp ". Generally speaking, this topic is poorly illuminated at the present time, mainly the technical descriptions of products, no more than that. The main resources do not contain the necessary information, presented in a "readable" form, therefore, I consider it necessary to shed light on this area. More detailed description of all products and specific characteristics (the possibility of order is also present) can be found on the site bpkarton.ru.

So, the electrocard . The wide use of this material is determined by its quality, durability and increased density. It differs by brand: EV, EVTNP - basic, and also in thickness (it is determined by the scope of application), for example, for the garment industry , higher strength is required, with variable thickness, thin grades of cardboard will be used for electrical insulation, and for the production of products where it is required Increased strength of the material - thickened marks (up to 3 mm). For example, an electrocardboard can be used in the manufacture of furniture, namely: to strengthen the form of the backs and sides of sofas and armchairs. In addition, they make patterns for the cutting of tapestries (see also electrocardboard for patterns ), leather, kozhezama and other materials that go to the upholstery. According to the technical description, it appears as a compact, wear-resistant grade of cardboard, which is optimally suited for various branches of light industry. Let's consider the most popular directions of its application.

The electrocardboard is widely used in sewing and leather goods manufacture (working name - cardboard for patterns ) as a material for making patterns and stencils. In general, what is a pattern? The calico, in fact, a pattern made of paper or cardboard (in particular, the brand "EV") from 0.1 to 0.5 mm in thickness. Why him? Yes, because it has the necessary properties such as strength, durability, necessary for working with frequently used items, for example, the above-mentioned patterns for sewing companies who "do not like" the shabby edges of these products. This material is delivered, as a rule, in rolls or sheets of various formats (in more detail - cardboard for patterns), it differs by the manufacturer and the minimum batch for ordering.

Another area of application - electrical units, namely - the electrical insulation of individual parts in them. Electrical insulating cardboard is made of 100% sulphate coniferous unbleached cellulose and is intended for: insulation for electrical equipment (transformers and other devices) with oil filling and operating temperature up to 105 degrees, as well as for manufacturing the main insulation parts in devices up to 220 kV And glued parts of all classes of transformers. Again, the same question: "why exactly?", But because the peculiarity of this brand is that the EV cardboard thickness of 0.1 to 0.8 mm (or 0.8 to 2.5 mm) is an excellent electrical insulator, due to the production technology. There are no other materials having such characteristics at such a low price. The choice is obvious and tested for years. For suppliers - this grade of cardboard can be purchased in rolls of width 1100 mm or sheets of various formats (see electrical insulating cardboard).

Generally speaking, this branch of industry is very highly specialized and does not need special advertising, because supplyers know what they need, and work with trusted suppliers, "not bothering" to find new ones. But sometimes it is necessary to highlight an alternative - the same material of high quality, but at a lower price. This is typical of suppliers who have recently been to the market. Their task is to declare themselves, through such a price policy and other bonuses, such as free shipping and the like. Sometimes it should be looked at, perhaps this is the beginning of a long, productive cooperation?
