Description

Mounting wire

The invention relates to the field of cable products, namely to the construction of assembly wires with combined insulation in a braid of glass fibers and can be used for movable and fixed installation inside equipment with control equipment for nuclear power plants, at an operating voltage of up to 400 V AC at a frequency of 50 Hz or DC voltage: up to 560 V.

Mounting wires are known, containing conductors; copper wires insulated with rubber like RTI-2. On top of twisted insulated Ш1Л and wrapped in cloth tape, is a cotton braid or rubber sheath (DS Bachelis et al. Electrical cables, cables and cords. M., Gosenergoizdat, 1963, p. 495).

However, these wires are designed to operate at temperatures no higher than -65 ° 0.

The task was to develop a construct of mokta;

wires characterized by high heat resistance and service life

combined thermoradiation resistance.

The technical result is achieved in that in a woHTajffiOM wire containing a conductive core, on top of which a four-layer winding of impregnated glass filaments and a braid of glass filaments varnished with organosilicon varnish are applied sequentially, the conductive 1-core is made of nickel-plated copper wires, and the four-layer winding filaments in layers and surface impregnated with organoilicate composition.

A more useful model is illustrated by a drawing on which the declared wire is cut in section.

The MONTE1 wire contains conductive wire: 1 slurry of nickel-plated copper wires, 4-layer winding 2 of impregnated glass filaments, 3 braid varnished with organosilicon varnish.

From the delivery drum, the bare wire (conductive core 1) enters the first bath with an organosilicate coating, in which an adhesive layer of the composition is applied to the wire. Then, in the first wrapper, the wire is wrapped in a first layer of glass filaments, which is impregnated in the second Vshn with an organosilicate composition and wrapped in a second wrapper with a second layer of glass ores in the reverse direction of the winding. Next, the wire enters the traction device, and from it into the third bath with the organosilicate composition, where the second layer of glass fibers is impregnated, after which the wire passes through the drying oven and is completely dried and fed to the receiving drum. Then a wire with two windings of glass filaments is wound on a delivery drum. From the feed drum, the wire enters the first bath with an organosilicate composition, then in the first winding, the wire is wrapped with a third layer of glass fibers, which is impregnated

in the second bath with an organosilicate composition and wrapped in the second wrapper with a fourth layer of glass fibers in the opposite direction

windings. Next, the wire enters the traction device, and from it into the third one with the organoilicate composition, where the fourth layer of insulation from glass fibers is impregnated, after which the wire passes through the drying oven and is completely dried and fed to the receiving drum.

braids on the wire, after which this wire enters the receiving drum

Braiding 3 wires is varnished on a horizontal glass winding machine. The braided wire from the transfer device enters the traction device, and from it into the third bath with an organosilicon varnish, where the braid of glass filaments is varnished, after which the wire passes through the drying oven and is completely dried and fed to the receiving drum.

The declared montalshy wire passed the tests for resistance to the influence of special factors (traditional; resistance) established by GOST V. 20. 39. 404-31. The electrical insulation resistance of the wire when exposed to special factors is 1 x 1U Ohm. m

In the technical conditions for the MGST brand wire, the above tests are not provided.

Service life: 7 S of the inventive wire is at least 30 years, 3 including 1200 hours at a temperature of 250 C, and the service life of the MGST brand wire is 5 years at a temperature of 200 C.
