PVA wire (PUGNP, PUGSP): technical parameters and interpretation of abbreviations
Electricity, numerous electrical appliances and mechanisms for various purposes in all spheres of human life and… wires, wires, wires! Wires and network cables are an industry today. They differ in brands, appointment, current conductivity and technical characteristics.
Alphanumeric marking of PVA
Today the range of these products is presented on the market in a wide range. At the buyer's choice - products with different design of cores and insulation coatings. All cables and wires are marked, which can determine the technical characteristics of these products and select the desired product for the desired purpose.
PVA wire, construction
PVA is a connecting wire in vinyl insulation . It consists of two or more copper, twisted and isolated multi-wire cores, dressed in a protective shell of polyvinyl chloride. Depending on the brand, PVA cable has a different cross-sectional shape and a different set and structure of conductive cores. The amount of copper (or aluminum) lived from 2 to 5, intersection in the range from 0,5 to 25 mm2, shell - rubber (rubberized) or traditional PVC. The color of the PVA insulation shell is white, black or gray. Insulation colors lived by the standard: brown, black and red-phase, blue - zero, yellow-green color - grounding.
Where PVA wire is used
Copper multicore PVA cable is used to transmit low signal voltage of low power devices. In everyday life, it is used to connect to the network of almost all electrical appliances and machines, providing voltage to 220/380 V, in the frequency range up to 50 Hz. It can be used for internal wiring of living quarters and for the work of specialized equipment in the garden.
PVA is widely used at some stages in industrial production. Thanks to that, that the PVA cable is well deformable and can withstand the maximum possible number of bends, it is very widely used for the manufacture of extension cords (transfer) of different lengths, as well as the installation of outdoor lighting and illuminated advertising.
PVA wire with aluminum core is designed for voltage transmission in urban electric lighting networks. Such wires are electrical equipment and wiring in modern residential buildings and factories, where high power is required: large metallurgical plants, enterprises of different specialization, power plant…
Features and benefits of PVA cable
The main characteristics of PVA:
-
The temperature of the environment of use from -40 to +40 degrees
- The maximum heating temperature of the conductor +70 degrees in the working phase
- Resource of trouble-free operation of a wire - 5000 hours, service life - 6 years
- PVA is resistant to corrosion, mold, fungus
- Not toxic, non-flammable
- The length of the construction cable is 50 meters
- Operating electrical resistance in the range 1 km is approximately equal to 270 Ohm
- At nominal stress, the resistance to variable deformation in bending is approximately from 30000 to 60000 cycles
PVA with copper cores has a number of advantages:
- Strength
- Plasticity
- High coefficient of resistance
- High conductivity
- High percentage of thermal expansion
- Anti-corrosion
- Easy repair
- Compatibility with regulating rheostats and insulators
Features of PVA with aluminum cores:
- Aluminum PVA cores are not heated, and this has a positive effect on the speed of electric current and its power
- Unlike copper, aluminum filaments are oxidized by oxides, which prolongs their service life and makes it possible to use them in chemical production, production of rolled metal
- PVA cable with aluminum core is more economical, as it weighs an order of magnitude less than copper. As a result, it has found its application in power transmission masts, as it allows to stretch lines without additional supports
- Aluminum wire is cheaper than copper, it is flexible and quite durable. The resource of wire use is minimal 5 years
Deciphering of PVA marking
All conductors, offered on the market of electrical equipment, have a marking certificate and must comply with the system of the State Standard of Russia. Distinguish these products by the abbreviation PVA, which represents the technical characteristics of the wire, purpose and scope of its use.
