Problems solved by technology
[0002] Modern urban buildings have higher and higher requirements for fire protection. With the continuous development of material technology, traditional wires can no longer meet the strict requirements of buildings for fire protection performance. However, ordinary fire-resistant wires are difficult to be popularized and applied in large areas due to their high prices; Existing fireproof cables are not resistant to extrusion and easy to break, and do not have the function of self-temperature measurement

Embodiment Construction
[0009] The present invention will be further described below in conjunction with accompanying drawing.
[0010] Such as figure 1 As shown, a kind of capacity-increasing fireproof wire according to the present invention includes a conductor 1, which is extruded outside the conductor 1 by 0.25-0.55mm 2 Insulation layer 2, extruded 0.25~0.55mm on the outermost layer of the cable 2 Outer sheath 3; said conductor is provided with an elastic reinforcing core 4, under the action of elasticity, the cable core is not easy to be broken; said outer sheath is provided with a symmetrical through hole 5, and said through hole is provided with The temperature measuring chip 6 can detect the temperature change of the cable; there are also multiple diamond-shaped grooves 7 on the outer sheath, which can prevent the cable from being squeezed by the outside, and play a certain buffer, and it is not easy to deform the wire layer inside the cable and squeeze.
[0011] The conductor is extruded ...

The invention discloses a capacity increasing fireproof wire, comprising a conductor, wherein an insulating layer of 0.25-0.55 mm<2> is extruded outside the conductor, and an outer sheath of 0.25-0.55 mm<2> is extruded on the outermost layer of the cable; an elastic reinforcing core is arranged in the conductor; the outer sheath is provided with a symmetrical through hole, and a temperature measuring chip is arranged in the through hole; and the outer sheath is further provided with a plurality of anti-extrusion rhombic grooves. The ceramic silicon rubber insulating layer extruded outside the conductor is foamed and sintered within short time at a high temperature or after catching fire to form a hard shell, the shell has the characteristics of no turndown and no re-ignition, and the material can improve the normal running temperature of the wire by 20 DEG C and improve the carrying capacity by 20-30%; the low-smoke halogen-free polyolefin material is extruded outside the insulating layer, so that the wire has the environment-friendly properties of flame retarding, low smoke amount during burning and the like; and compared with a wire completely made of ceramic silicon rubber, the material cost can be greatly reduced and the wire is beneficial to large-area promotion in the market.
Description
technical field [0001] The invention relates to the field of electric wire manufacturing, in particular to a capacity-enhancing fireproof electric wire. Background technique [0002] Modern urban buildings have higher and higher requirements for fire protection. With the continuous development of material technology, traditional wires can no longer meet the strict requirements of buildings for fire protection performance. However, ordinary fire-resistant wires are difficult to be popularized and applied in large areas due to their high prices; Existing fireproof cables are not resistant to extrusion and are easy to break, and do not have the function of self-measurement of temperature. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention provides a wire that meets the technical requirements of fire prevention and environmental protection of wires, increases the ampacity of wires, and at the same time, the manufa...
