Abstract
The utility model discloses a fire-proof wire composed of a conductor core wire and a polyvinyl chloride (PVC) sleeve sleeved outside the core wire, wherein the core wire is a copper wire, and a mica layer is arranged between the PVC sleeve and the core wire. The fire-proof wire is provided with good fire resistance performance and can bear much great mechanical impact; and the insulating property of the wire cannot be affected at a high temperature.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, is specifically related to a kind of flame-proof wire.
Background technology
Electric wire is the lead of conduction current; Be mainly used in electric power, communication and correlated current transmission field; It mainly is made up of conductor core wire and the outer insulating case of heart yearn, and heart yearn is made up of copper cash, aluminum steel etc., and this electric wire does not have fire-proof function; Insulating case is prone to melt after running into naked light or high temperature, and security performance is had a greatly reduced quality.
The utility model content
The purpose of the utility model provides a kind of electric wire that possesses fire-proof function.
The utility model solves the technical scheme that its technical problem adopted: a kind of flame-proof wire, and comprise conductor core wire and be placed in the outer PVC cover of heart yearn, be provided with mica layer between described PVC cover and the heart yearn.
Wherein, described heart yearn is a copper cash.
The beneficial effect of the utility model is: be provided with mica layer between PVC cover and the heart yearn, electric wire has just possessed the good fire resistance ability like this, and can also bear sizable mechanical impact, and the insulation property of electric wire can not be affected yet when running into high temperature.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
With reference to shown in Figure 1; The utility model discloses a kind of flame-proof wire, comprise conductor core wire 1 and be placed in heart yearn 1 outer PVC and overlap 3, described heart yearn 1 is a copper cash; Be provided with mica layer 2 between described PVC cover 3 and the heart yearn 1; Electric wire has just possessed the good fire resistance ability like this, and can also bear sizable mechanical impact, and the insulation property of electric wire can not be affected yet when running into high temperature.
The foregoing description is the principle and the effect thereof of illustrative the utility model only; And the embodiment of part utilization; For the person of ordinary skill of the art; Under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection range of the utility model.
