KG 380
Design elements:
- The conducting vein twisted from copper (KG, KG-HL) or copper tinned (KG-t) a provolok (class 5);
- Layer from a polietilentereftalatny film of the PET-E brand;
- Isolation from rubber of the RTI-1 or RTI-1-HL type on the basis of natural and butadiene rubbers. Marking of the isolated veins:
• digital: 1, 2, 3, 4, 5, a grounding vein - 0,
• color: blue, black, brown, a grounding vein - greenish-yellow; - Layer from a polietilentereftalatny film of the PET-E brand (over the twisted isolated veins);
- Cover from rubber of the RShT-2, RShTM-2-HL type on the basis of isoprene and butadiene rubbers; an insulating and protective cover of single-conductor cables from rubber like RTIShM, RTISh-HL on the basis of isoprene and butadiene rubbers.
Scope:
Cables are intended for connection of mobile mechanisms to electric networks on a rated alternating voltage of 380 V of frequency to 400 Hz or the constant rated voltage of 660 Century.
Type of a climatic modification of cables U, HL, T of categories of placement 1, 2, 3 in accordance with GOST 15150. Cables are steady against influence of sunlight. In tropical execution of a rack to defeat by mold mushrooms.
Service life - not less than 4 years.
Repeated excesses of a cable through system of rollers:
Diameter of rollers | The stretching loading | Section of the main veins | Number of cycles of excesses |
120 mm | 15 N | 2,5 sq. mm | 30 000 |
200 mm | 20 N | 4,0 sq. mm | 30 000 |
Repeated bends of a cable on a corner ±П/2 I am glad at the stretching effort 49 N:
Diameter of rollers | Section of the main veins | Number of cycles of bends |
200 mm | from 6,0 to 16 sq. mm | 90 000 |
200 mm | from 25 to 50 sq. mm | 60 000 |
400 * mm | from 70 to 120 sq. mm | 40 000 |
-----------------------------------------
* for single-conductor cables diameter of a roller has to be no more than 200 mm.
