VVG cable of various types and purposes
Distribution of electrical energy from suppliers' power lines through consumer substations is carried out using a wired circuit. It is calculated during engineering design and installed using consumables of the established (design type). A special power supply is used VVG cable, the design of which is as follows:
- Copper conductors with a certain cross-sectional area.
- Protective (insulating) sheath made of polyvinyl chloride plastic.
Standard technical parameters – operating voltage up to 1000 V, rated alternating voltage no more than 660 V, current frequency 50 Hz. Installation of this type of cable can be carried out by air or through channels, in heated or damp cold rooms. Taking into account the specifics of operation, the following types are distinguished:
Non-flammable cable
The designation generally accepted for engineering and technical reference books and supplier catalogs is VVGng cable is decrypted , as in “Vinyl-Vinyl-Naked-Non-Flammable.” The abbreviation means:
- “B” - each of the cores has polyvinyl chloride insulation.
- “B” - general external PVC insulation.
- “ng » - non-flammable plastic. When heated, it does not emit caustic smoke or toxic substances.
The product is recommended or required for installation of wired electrical networks in rooms (places) with a high fire hazard category.
Flat cable
Taking into account the specifics and technical capabilities of laying certain lines of electrical networks, a special flat cable is used. It is designated by the abbreviation VVG-P (flat). Dimensional parameters depend on the number and cross-sectional area of the cores. Indicated by the manufacturer in the technical data sheet and catalog description.
Classification by climatic version
When installing the VVG cable in an open space (outdoors), the climatic version of the product is taken into account. The designation is as follows:
- “T” - tropical.
- “UHL” - moderately cold.
Wide choice and help in selection
You can get acquainted with the types and technical characteristics of VVG high-voltage electrical cables using the company’s website “elektrikua.com.ua”. Each item presented on the pages of the catalog is accompanied by a detailed description. Consultation with interested clients is carried out by a full-time specialist by telephone or via Internet messengers.
The sale of cable products and consumables necessary for installation is carried out with the possibility of making a purchase in an online format. Guarantees of quality and affordable competitive prices from a direct supplier are provided.
