Abstract

A fire-proof high-temperature resistant fluorescence radiation cable is disclosed. The cable contains a copper stranded wire conductor (1), a phlogopite tape (2), an insulating layer (3), a wire armoring layer (4), an inner sheath (5), a cooling fire-proof pipe (6), a fluorescence inducing luminous band (7) and a transparent sheath (8) which are successively arranged from inside to outside. The cable provided by the utility model can be automatically cooled, can also be normally used under the high-temperature condition, and can fluoresce when electrified through alternating current. According to the utility model, it can indicate that the cable is in a power-up state, and a certain illumination can also be provided in a dark environment.

Description

A kind of fireproof high-temperature resistant fluorescence radiation cable

Technical field

The utility model relates to the power cable technical field, specifically is to say a kind of fireproof high-temperature resistant fluorescence radiation cable.

Background technology

At present, living and producing used cable has plain conductor in generally all being, is made up of insulating barrier outward, under the help that does not have special equipment, is difficult to determine whether cable itself is charged, wants extreme care in operating process, otherwise is easy to the people is caused injury.In addition, under situations such as breaking out of fire, earthquake, it is dark that environment can become, if having luminous object can indicate people to escape this moment, will reduce a lot of loss of life or personal injury.

The utility model content

At the problems referred to above that prior art exists, the applicant provides a kind of fireproof high-temperature resistant fluorescence radiation cable.This cable can also can normally use under hot conditions from cooling, and can send fluorescence during by alternating current, not only can indicate cable to be in "on" position, and can also provide certain illumination under dark surrounds.

The technical solution of the utility model is as follows:

A kind of fireproof high-temperature resistant fluorescence radiation cable, described cable is followed successively by from inside to outside: copper stranded conductor conductor (1), phlogopite band (2), insulating barrier (3), wire armoring layer (4), inner sheath (5), cooling fire protection pipe (6), the inducing luminous band of fluorescence (7), transparent sheath (8).

Described cooling fire protection pipe (6) is divided into three layers, the inner cooling agent of filling, and both sides are heat release layer, the heat release layer of described both sides wraps the cooling agent of described inside.Described copper stranded conductor conductor (1) is regular stranded, and its lay ratio is from inside to outside deferred to " 7 add 2 " rule, is followed successively by 7,9,11 ...

The utility model beneficial technical effects is:

The cooling fire protection pipe periphery of this cable is heat release layer; the inner cooling agent of filling; to reach the effect of fire prevention cooling; can under hot conditions, lower the temperature to cable; and can have under the situation of fire cable generation protection; make cable body part especially insulation and the inner liner portion of cable do not produce thermokarst phenomenon, its conductive coefficient (normal temperature) is 0.012 kcal/ (mh ℃), bearing temperature is not less than 800 ℃.The heat that heat release layer is convenient to produce under cable self load distributes.In addition, the phlogopite band of cable also is flame retardant coating, has played the refractory protection effect equally.

Be the inducing luminous band of fluorescence outside the cooling fire protection pipe, wrapped with fluorescent belt, it is luminous to respond to generation magnetic during by crosslinked electric current, the energy long period is luminous in dark surrounds, for dark surrounds provides certain illumination indication, as run into contingency and can play emergent luminous indication escaping, effectively having reduced unnecessary loss, can also avoid in addition accidentally injuring cable and causing the accident at the environment of dim light.Be provided with transparent sheath outside the inducing luminous band of fluorescence, sheath is weather resistant, can prolong the useful life of cable, plays the effect of protection cable luminous element.

Description of drawings

Fig. 1 is the structural representation of this fireproof high-temperature resistant fluorescence radiation cable.

Embodiment

Below in conjunction with accompanying drawing, the utility model is specifically described.

This cable is provided with 8 layers from inside to outside altogether, is followed successively by: copper stranded conductor conductor 1, phlogopite band 2, insulating barrier 3, wire armoring layer 4, inner sheath 5, cooling fire protection pipe 6, fluorescence is inducing luminous is with 7, transparent sheath 8.

Described copper stranded conductor conductor 1 is regular stranded, and its lay ratio is from inside to outside deferred to " 7 add 2 " rule, is followed successively by 7,9,11 Described phlogopite band 2 is refractory material; Described insulating barrier 3 can be selected 125 ℃ of irradiated crosslinking low-smoke and halogen-free flame retardant oil resistant polyolefin for use; Described wire armoring layer 4 not only provides the rigidity of cable, and can prevent fires by fire insulation; Described cooling fire protection pipe 6 is divided into three layers, the inner cooling agent of filling, and both sides are heat release layer, and from the inside and outside cooling agent that coats described inside of clamping, cooling agent can be from cooling respectively for the heat release layer of described both sides, and heat release layer can be distributed the heat that the cable energising produces.
