- shape;
- condition of surface finish;
- chemical composition;
- mechnical properties and other traits.
According to GOST 2333-74
the wire is classified by:
- uncoated or zinc-coated steel wire per GOST
7372-79 ;
- organic or metal core. Organic cores are made of cotton and polymer thread bast fiber (hemp, sisal, abaca) and cord.

- ËÊ -ÐÎ – cables for operation in hostile environments.
Depending on its designation, the wire is made from different steel grades: commercial wire per
GOST 3282 - from rod and from low-carbon steel per
GOST 1050-74
; spring wire per
GOST 9389-75 - from carbon steel with 0.4 –
1.0% carbon content, alloyed spring wire per
GOST
14963-78 60Ñ2À, 65Ñ2ÂÀ, quality grade wire –
from such steel grades as: 08êï, Ñò10, Ñò10ïñ, Ñò15êï, Ñò20, Ñò35, Ñò40 & Ñò50 etc.
Cable is a product composed of the following materials:
Cable lines are subdivided by several characteristic features including:
