Embodiment Construction

[0012] like figure 1 As shown in the figure, a ceramized silicon rubber insulated fireproof cable according to the present invention includes a cable core, the cable core is formed by twisting a plurality of insulated wire cores, the gaps in the cable core are filled with flame retardant filler 3, and the cable core is filled with flame retardant filler 3 The core is extruded with an armor layer 4, and the outermost layer is extruded with a low-smoke and non-toxic plastic material outer sheath 5. The insulated wire core is composed of a conductor 1 and a ceramic silicon rubber insulating layer 2 wrapped around the conductor 1 .

[0013] Raw material selection and production process of the present invention:

[0014] 1) Cable conductor:

[0015] It is formed by twisting multiple strands of copper wires to the opposite stranded conductor structure. After twisting, the outer diameter is close, the twisting rate is the same, and the twisting direction is opposite, so this struct...

Abstract

The invention discloses a vitrified silicon rubber insulation fireproof cable which comprises a cable core, wherein the cable core is formed by stranding a plurality of insulation wire cores; a flame resistance filler is filled in a gap in the cable core; an armor layer is extruded on the cable core; and an outer sheath is extruded on the outermost layer. Each insulation wire core consists of a middle conductor and a vitrified silicon rubber insulation layer wrapping the conductor. Large-length and high-specification production is realized; a product is soft and convenient to assemble and lay; the number of middle joints is small; and the performance can completely meet the standard requirement of ore insulation cables.

Description

[0001] technical field [0002] The invention belongs to the field of power cables, in particular to a ceramicized silicon rubber insulated fireproof cable. Background technique [0003] At present, the most commonly used fireproof cables on the market are mineral insulated cables. The copper conductive core, copper outer sheath and insulating layer of the traditional mineral insulated cable are densely integrated. It has a history of nearly 80 years in foreign production and use, and nearly 20 years in domestic production and use. It has been widely used in many large projects, and the effect is very good; but because the production process of mineral insulated cables is more complicated, the price is higher, the hardness is higher, and it is not easy to bend during construction, so both in terms of cost reduction and construction technology, it is The length of the order must be required to be fairly accurate. At the same time, since the cross-sectional area of ​​the cab...
