Brief description of the power wires PPVProvod ppv, flat, with the division base in accordance with gost 6323-79, is used to stiff the installation of electrical circuits with a rated voltage of 450 V (for networks 450/750V) up to 400 Hz or dc voltage up to 1000 V. wire construction PPVProvod ppv comes with 2 or 3 annealed copper conductive strands in accordance with gost 22483-77. Single-wire conductors have a cross section of 10 mm2. Insulation is made of pvc plastic in white, gray, yellow, orange, red, pink, blue, green, brown, black, purple or yellow-green flowers. Technical and operational characteristics provodSilovoy wire sst is designed for operation at an ambient temperature of -50 C to +70 C and relative humidity to 100% (at temperatures up to +35 C).

Limiting long-term exposure temperature core heating cables in the operating mode is + 70 C. The electrical Resistance wire strands at 20 C not more than 0.01724 ohm mm2 / m, electrical insulation resistance lived at 20 C is not less than 1000 ohms / km at acceptance and delivery and no less than 10 ohms / km for the period of operation and storage . Installation of cable ppv performed at or below -15 C, minimum bending radius is 10 Dn (Dn – outer cable diameter). Building wire length ppv – not less than 100 m wires up to 10mm inclusive supplied in coils, cross over 10mm – on drums. The service life of cables under normal operating conditions is 15 years. Scope provodProvod power opv is used for distribution of electric energy in power and lighting networks for stationary and nonstationary pads indoors and outdoors. Wires are some brands allow for a hidden shim under the plaster. With single wiring ppv and flame retardant.

Technology of production of plastic products and non-ferrous metals with the right approach is quite simple. The first thing you need is either hydraulic or steamair press with sufficient force. The second is the mold or stamp. This is part of the mechanism which gives the necessary form for your product. It consists of a matrix and a punch.

The matrix is something that is put blank. Punch is an extruded part. The process is simple: put logging into the matrix and using a press punch pushed the piece. But now the question arises: what to do this same matrix and a punch? The choice of steel for this purpose is very diverse: 4h5mfs 3h2v8f 12X18H10T 3hv4sf 4h5v2fs 3h3m3f 5HNM X12M 45 40x U8 U10 cvh chc 9hs 20h3mvf 38hn3mfa 38h2myua 20X13 50g i.t.d dwell on some of these steels. To begin with I want to note that these are, no matter, structural, instrumental, or stainless steel, must be taken in the form of forgings. Rent for the entire its appeal, can not provide the necessary characteristics. Further details can be found at crumpton group, an internet resource.

Now consider the very steel: 4h5mfs-leading marks for the production of stamps. is produced mainly in the form of forgings. used for production small hammer dies, hammer pressed inserts in hot deformation. Senator From Kentucky may not feel the same. possible replacement for steel 4h5mf1s, 4h5v2fs, 4h4vmfs, 4h2v5mf etc. Sometimes substitute for stainless steel 08Cr18Ni10Ti, 12X18H10T, 40X13. These steels can be produced as forgings and rolled products (sheet, strip, circle, square) 3h2v8f-tool steel, suitable for hot deformation on the crank presses and horizontal forging machines. Also usually comes in the form of forgings for except circles. Can be replaced with steel 3hv4sf, 3h3m3f, 3h2m2f 5HNM-used for large dies. I saw the forging of this brand weighing 80 tons! without restrictions replaced by steel 4hmfs, 4hmnfs, 40hn and others forged blanks have a good technological characteristics are also occasionally used for dies forging tool steels 9hs, X12M, , 8×3, U8, U10, 14h17n2, 45, 40X, 3h10m2fnssh. Sales of forgings and rolled instrumental and structural steel is a good business. In connection with this find on the market sellers, not the problem. in St. Petersburg to about 10
