Abstract
The utility model discloses a special silicon rubber cable, which is characterized in that the core wire adopts flexible conductors, and the periphery of the flexible conductor is provided with a composite silicone rubber insulating layer. Each core wire covered with the composite silicone rubber insulating layer is inserted in high temperature resistance fillers whose periphery is provided with a high temperature resistance nonwoven winding layer, and the outermost layer is provided with a composite silicone rubber protective sheath. The utility model has the advantages of high temperature resistance, corrosion resistance, acid and alkaline resistant and soft structure. The special silicon rubber cables which can be used in oil water for long time is suitable for serving as a power supply cable or an electric connection under 1 kv alternate current rated voltage.
Description
Technical field:
The utility model relates to the cable that can be used as the power supply or be electrically connected usefulness.
Background technology:
At present, being applied in the cable in the metallurgical engineering project, is to be insulation and sheath material with the vinylsiloxane rubber, but because the limitation of the performance of material own, the thermal endurance class of its finished product is only at 180 ℃, and tensile strength only is 4-5N/mm
2, can not satisfy various application scenario.
Summary of the invention:
The utility model is for solving the problem that above-mentioned prior art exists, and provides a kind of have good heat resistance, special silicone rubber cable that tensile strength is high, to adapt to various application scenario.
The technical scheme that the utility model technical solution problem is adopted is:
Design feature of the present utility model is that heart yearn adopts flexible conductor, periphery at flexible conductor is the composite silicone rubber insulating barrier, the heart yearn that each root is coated with the composite silicone rubber insulating barrier is embedded in high temperature resistant filler, the periphery of filler is high temperature resistant nonwoven fabrics lapping layer, and at outermost layer the composite silicone rubber sheath is set.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utlity model has excellent properties such as high temperature resistant, corrosion-resistant, acid and alkali-resistance, structurally flexible, can in profit, use for a long time.Be applicable to and make service cable below the ac rated voltage 1KV or be electrically connected usefulness.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Number in the figure: 1 flexible conductor, 2 insulating barriers, 3 fillers, 4 lapping layers, 5 sheaths.
Embodiment:
Referring to accompanying drawing, in the present embodiment, heart yearn adopts flexible conductor 1, periphery at flexible conductor 1 is a composite silicone rubber insulating barrier 2, the heart yearn that each root is coated with composite silicone rubber insulating barrier 2 is embedded in high temperature resistant filler 3, the periphery of filler 3 is high temperature resistant nonwoven fabrics lapping layer 4, and at outermost layer composite silicone rubber sheath 5 is set.
In concrete the enforcement, flexible conductor 1 is the oxygen-free copper tow, and composite silicone rubber insulating barrier 2 is the anti-silk of an existing height composite silicone rubber.Composite silicone rubber insulating barrier 2 is a continuously extruding and molding, and composite silicone rubber sheath 5 also is a continuously extruding and molding.
