Self-retaining cables 6 It is a string or six-wire cable that is used in low voltage power distribution lines in Iran. Market demand has led to significant production and sales of this type of overhead cable in the statistics.
The design and production of power cables is in accordance with several principles. Standards and technical requirements set by standard authorities and related organizations and the needs of users and the conditions governing the electricity network are the most important principles for the production of these cables.. Low voltage self-supporting cables are also produced and supplied based on the same criteria.
Self-retaining cables 6 field
Low voltage self-supporting cables are made with a number of different strands or wires. In the three-phase type of these cables, there are two groups 5 The area was 6 Wires are common in Iranian electricity networks. Self-supporting cable structure 6 The wire is like this :
- Three strings for phases : They are detected by thorns or longitudinal protrusions on the insulation. Phases have one, two and three spines.
- A string for the pass phase (Illustrated) : This string has no thorns.
- A string for zero : The insulation surface of this string is full of thorns, for which the term thousand thorns is used.
- A string holder (Messenger) : It is smooth and without spines, and often the cable specifications are inserted on this string.
Material of self-supporting cable components
- The conductor for phase and neutral filaments is made of aluminum.
- Retaining wire in self-supporting cable 6 The string is made of galvanized steel.
- The insulation used in this product is mostly crosslinked polyethylene (XLPE) Is.
Self-supporting wires and cables crosslink after being extruded in the steam room under high steam temperature and pressure. Crosslink action has a great effect on improving the electrical, mechanical and UV resistance properties of cable. In self-supporting cable, the retaining string is responsible for withstanding all mechanical forces.
Self-supporting cable sizes 6 field
In accordance with the criteria Tavanir Companyسای The size of the strands of low pressure self-supporting cables (0.6/1 KV) This is it :
- ١٦+١٦+٢٥+٢٥*٣
- ٢٥+٢٥+٣٥+٣٥*٣
- ٢٥+٢٥+٥٠+٥٠*٣
- ٢٥+٢٥+٧٠+٧٠*٣
- ٢٥+٢٥+٩٥+٩٥*٣
- ٢٥+٢٥+١٢٠+١٢٠*٣
Supply of low voltage self-supporting cables
Selling all kinds of low voltage self-supporting cables, including :
- Weak single-phase three-wire pressure
- Low voltage three-phase five-wire
- Weak three-phase pressure 6 Area
It is done with a variety of sizes and quality categories. Simkan self-supporting cables are produced in accordance with the standards and are provided according to customers' requests from Tavanir certified samples or power distribution companies..
